• Notes from AT&T ARO Session at Oredev 2013

  - by Geertjan

  The mobile internet is 12 times bigger than internet was 12 years ago. Explosive growth, faster networks, and more powerful devices. 85% of users prefer mobile apps, while 56% have problems. Almost 60% want less than 2 second mobile app startup. App with poor mobile experience results in not buying stuff, going to competitor, not liking your company. Battery life. Bad mobile app is worse than no app at all because it turns people away from brand, etc. Apps didn't exist 10 years ago, 72 billion dollars a year in 2013, 151 billion in 2017.Testing performance. Mobile is different than regular app. Need to fix issues before customers discover them. ARO is free and open source AT&T tool for identifying mobile app performance problems. Mobile data is different -- radio resource control state machine. Radio resource control -- radio from idle to continuous reception -- drains battery, sends data, packets coming through, after packets come through radio is still on which is tail time, after 10 seconds of no data coming through radio goes off. For example, YouTube, e.g., 10 to 15 seconds after every connection, can be huge drain on battery, app traffic triggers RRC state. Goal. Balance fast network connectivity against battery usage. ARO is free and open source and test any platform and won awards. How do I test my app? pcap or tcdump network. Native collector: Android and iOS. Android rooted device is needed. Test app on phone, background data, idle for ads and analytics. Graded against 25 best practices. See all the processes, all network traffic mapped to processes, stats about trace, can look just at your app, exlude Facebook, etc. Many tests conducted, e.g., file download, HTML (wrapped applications, e.g., cordova). Best Practices. Make stuff smaller. GZIP, smaller files, download faster, best for files larger than 800 bytes, minification -- remove tabs and commenting -- browser doesn't need that, just give processor what it needs remove wheat from chaff. Images -- make images smaller, 1024x1024 image for a checkmark, swish it, make it 33% smaller, ARO records the screen, probably could be 9 times smaller. Download less stuff. 17% of HTTP content on mobile is duplicate data because of caching, reloading from cache is 75% to 99% faster than downloading again, 75% possible savings which means app will start up faster because using cache -- everyone wants app starting up 2 seconds. Make fewer HTTP requests. Inline and combine CSS and JS when possible reduces the number of requests, spread images used often. Fewer connections. Faster and use less battery, for example, download an image every 60 secs, download an add every 60 seconds, send analytics every 60 seconds -- instead of that, use transaction manager, download everything at once, reduce amount of time connected to network by 40% also -- 80% of applications do NOT close connections when they are finished, e.g., download picture, 10 seconds later the radio turns off, if you do not explicitly close, eventually server closes, 38% more tail time, 40% less energy if you close connection right away, background data traffic is 27% of data and 55% of network time, this kills the battery. Look at redirection. Adds 200 to 600 ms on each connection, waterfall diagram to all the requests -- e.g., xyz.com redirect to www.xyz.com redirect to xyz.mobi to www.xyz.com, waterfall visualization of packets, minimize redirects but redirects are fine. HTML best practices. Order matters and hiding code (JS downloading blocks rendering, always do CSS before JS or JS asynchronously, CSS 'display:none' hides images from user but the browser downloads them which adds latency to application. Some apps turn on GPS for no reason. Tell network when down, but maybe some other app is using the radio at the same time. It's all about knowing best practices: everyone wins with ARO (carriers, e.g., AT&T, developers, customers). Faster apps, better battery usage, network traffic better, better app reviews, happier customers. MBTA app, referenced as an example.ARO is free, open source, can test all platforms.

• How to use onSensorChanged sensor data in combination with OpenGL

  - by Sponge

  I have written a TestSuite to find out how to calculate the rotation angles from the data you get in SensorEventListener.onSensorChanged(). I really hope you can complete my solution to help people who will have the same problems like me. Here is the code, i think you will understand it after reading it. Feel free to change it, the main idea was to implement several methods to send the orientation angles to the opengl view or any other target which would need it. method 1 to 4 are working, they are directly sending the rotationMatrix to the OpenGl view. all other methods are not working or buggy and i hope someone knows to get them working. i think the best method would be method 5 if it would work, because it would be the easiest to understand but i'm not sure how efficient it is. the complete code isn't optimized so i recommend to not use it as it is in your project. here it is: import java.nio.ByteBuffer;

• Android app crashes on emulator - logCat shows no errors

  - by David Miler

  I have just added the SherlockActionBar library to my android project. After some small changes (FragmentActivity - SherlockFragmentActivity, getActionBar() - getSupportActionBar(), imports) it all compiled nicely. After I run the app, however, the debugger stops, as though it had encountered an exception. However, there are no errors shown in the LogCat output. I just can't wrap my head around what's going on. Here is the logCat output after I terminate the app. 10-02 14:11:19.227: I/SystemUpdateService(174): UpdateTask at time 1349187079227 10-02 14:11:19.237: I/ActivityThread(328): Pub com.android.email.attachmentprovider: com.android.email.provider.AttachmentProvider 10-02 14:11:19.687: I/dalvikvm(81): Jit: resizing JitTable from 512 to 1024 10-02 14:11:19.809: D/MediaScannerService(150): start scanning volume internal: [/system/media] 10-02 14:11:20.047: V/AlarmClock(239): AlarmInitReceiver finished 10-02 14:11:20.087: I/ActivityManager(81): Start proc com.android.quicksearchbox for broadcast com.android.quicksearchbox/.SearchWidgetProvider: pid=346 uid=10012 gids={3003} 10-02 14:11:20.127: D/ExchangeService(320): !!!

• HTML5 Form: Page Is Reloading Instantly After Restyling (And It Shouldn't Be)

  - by user3689753

  I have a form. I have made it so that if your name is not put in, a red border is put on the name field. That works, BUT...it's for a split second, and then the page reloads. I want the red border to appear, and then stay there. For some reason it's for a split second. Can someone help me make it so the page doesn't reload after displaying the red border? Here's the script. window.onload = function() { document.getElementById("Hogwarts").onsubmit = function () { window.alert("Form submitted. Owl being sent..."); var fname = document.getElementById("fName"); if(!fName.value.match("^[A-Z][A-Za-z]+( [A-Z][A-Za-z]*)*$")) { window.alert("You must enter your name."); addClass(fName, "errorDisp"); document.getElementById("fName").focus(); } else return true; } } function addClass(element, classToAdd) { var currentClassValue = element.className; if (currentClassValue.indexOf(classToAdd) == -1) { if ((currentClassValue == null) || (currentClassValue === "")) { element.className = classToAdd; } else { element.className += " " + classToAdd; } } } function removeClass(element, classToRemove) { var currentClassValue = element.className; if (currentClassValue == classToRemove) { element.className = ""; return; } var classValues = currentClassValue.split(" "); var filteredList = []; for (var i = 0 ; i < classValues.length; i++) { if (classToRemove != classValues[i]) { filteredList.push(classValues[i]); } } element.className = filteredList.join(" "); } Here's the HTML. <!DOCTYPE HTML> <html lang="en"> <head> <meta charset="UTF-8" /> <meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1"> <title>Hogwarts School of Witchcraft And Wizardry Application Form</title> <link rel="stylesheet" type="text/css" href="main.css" media="screen"/> <script src="script.js" type="text/javascript"></script> </head> <body> <section> <header> <h1>Hogwarts School of Witchcraft And Wizardry</h1> <nav></nav> </header> <main> <form method="post" id="Hogwarts"> <!--<form action="showform.php" method="post" id="Hogwarts">--!> <fieldset id="aboutMe"> <legend id="aboutMeLeg">About Me</legend> <div class="fieldleading"> <label for="fName" class="labelstyle">First name:</label> <input type="text" id="fName" name="fName" autofocus maxlength="50" value="" placeholder="First Name" size="30"> <label for="lName" class="labelstyle">Last name:</label> <input type="text" id="lName" name="lName" required maxlength="50" value="" placeholder="Last Name" pattern="^[A-Za-z ]{3,}$" size="30"> <label for="age" class="labelstyle">Age:</label> <input type="number" id="age" name="age" required min="17" step="1" max="59" value="" placeholder="Age"> </div> <div class="fieldleading"> <label for="date" class="labelstyle">Date Of Birth:</label> <input type="date" name="date1" id="date" required autofocus value=""> </div> <div id="whitegender"> <div class="fieldleading"> <label class="labelstyle">Gender:</label> </div> <input type="radio" name="sex" value="male" class="gender" required="required">Male<br/> <input type="radio" name="sex" value="female" class="gender" required="required">Female<br/> <input type="radio" name="sex" value="other" class="gender" required="required">Other </div> </fieldset> <fieldset id="contactInfo"> <legend id="contactInfoLeg">Contact Information</legend> <div class="fieldleading"> <label for="street" class="labelstyle">Street Address:</label> <input type="text" id="street" name="street" required autofocus maxlength="50" value="" placeholder="Street Address" pattern="^[0-9A-Za-z\. ]+{5,}$" size="35"> <label for="city" class="labelstyle">City:</label> <input type="text" id="city" name="city" required autofocus maxlength="30" value="" placeholder="City" pattern="^[A-Za-z ]{3,}$" size="35"> <label for="State" class="labelstyle">State:</label> <select required id="State" name="State" > <option value="Select Your State">Select Your State</option> <option value="Delaware">Delaware</option> <option value="Pennsylvania">Pennsylvania</option> <option value="New Jersey">New Jersey</option> <option value="Georgia">Georgia</option> <option value="Connecticut">Connecticut</option> <option value="Massachusetts">Massachusetts</option> <option value="Maryland">Maryland</option> <option value="New Hampshire">New Hampshire</option> <option value="New York">New York</option> <option value="Virginia">Virginia</option> </select> </div> <div class="fieldleading"> <label for="zip" class="labelstyle">5-Digit Zip Code:</label> <input id="zip" name="zip" required autofocus maxlength="5" value="" placeholder="Your Zip Code" pattern="^\d{5}$"> <label for="usrtel" class="labelstyle">10-Digit Telephone Number:</label> <input type="tel" name="usrtel" id="usrtel" required autofocus value="" placeholder="123-456-7890" pattern="^\d{3}[\-]\d{3}[\-]\d{4}$"> </div> <div class="fieldleading"> <label for="email1" class="labelstyle">Email:</label> <input type="email" name="email1" id="email1" required autofocus value="" placeholder="[email protected]" pattern="^[a-z0-9._%+-]+@[a-z0-9.-]+\.[a-z]{2,4}$" size="35"> <label for="homepage1" class="labelstyle">Home Page:</label> <input type="url" name="homepage1" id="homepage1" required autofocus value="" placeholder="http://www.hp.com" pattern="https?://.+" size="35"> </div> </fieldset> <fieldset id="yourInterests"> <legend id="yourInterestsLeg">Your Interests</legend> <label for="Major" class="labelstyle">Major/Program Choice:</label> <select required id="Major" name="Major" > <option value="">Select Your Major</option> <option value="Magic1">Magic Horticulture</option> <option value="Magic2">Black Magic</option> <option value="White">White Magic</option> <option value="Blue">Blue Magic</option> <option value="Non">Non-Wizardry Studies</option> </select> </fieldset> <button type="submit" value="Submit" class="submitreset">Submit</button> <button type="reset" value="Reset" class="submitreset">Reset</button> </form> </main> <footer> &copy;

• GooglePlayServicesNotAvailable: GooglePlayServices not available due to error 1

  - by Mathias Lin

  I'm on Galaxy S III with Android 4.0.4, Google Play installed. In my app I try to get a token from the Google Play services, as described on https://developers.google.com/android/google-play-services/authentication. Since it's all quite new (the Google pages were last updated this week), there's not much documentation to be found, especially about each specific error code. final String token = GoogleAuthUtil.getToken(this, "[email protected]", "scope"); gives me an exception: 09-30 11:24:36.075: ERROR/GoogleAuthUtil(11984): GooglePlayServices not available due to error 1 09-30 11:24:36.105: ERROR/AuthTokenCheck_(11984): Error 1 com.google.android.gms.auth.GooglePlayServicesAvailabilityException: GooglePlayServicesNotAvailable at com.google.android.gms.auth.GoogleAuthUtil.f(Unknown Source) at com.google.android.gms.auth.GoogleAuthUtil.getToken(Unknown Source) at com.google.android.gms.auth.GoogleAuthUtil.getToken(Unknown Source) at mobi.app.activity.AuthTokenCheck.getAndUseAuthTokenBlocking(AuthTokenCheck.java:148) at mobi.app.activity.AuthTokenCheck$1.doInBackground(AuthTokenCheck.java:61) at android.os.AsyncTask$2.call(AsyncTask.java:264) at java.util.concurrent.FutureTask$Sync.innerRun(FutureTask.java:305) at java.util.concurrent.FutureTask.run(FutureTask.java:137) at android.os.AsyncTask$SerialExecutor$1.run(AsyncTask.java:208) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1076) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:569) at java.lang.Thread.run(Thread.java:856) https://developers.google.com/android/google-play-services/reference/com/google/android/gms/auth/package-summary tells me: GooglePlayServicesAvailabilityExceptions are special instances of UserRecoverableAuthExceptions which are thrown when the expected Google Play services app is not available for some reason. But what exactly does that mean? And how to resolve it? I've added the Google Play services extras in my SDK and the jar to my project, marked as 'exported'. I'm also wondering what the "Google Play services app" exactly is. Unfortunately it's all not very clearly described at https://developers.google.com/android/google-play-services/. The Google Play services component is delivered as an APK through the Google Play Store, so updates to Google Play services are not dependent on carrier or OEM system image updates. Newer devices will also have Google Play services as part of the device's system image, but updates are still pushed to these newer devices through the Google Play Store. Isn't "Google Play services" app the same as the "Google Play" app? Another question I have, due to lack of documentation: what is the scope parameter for? The documentation just says the following, but not defining what an 'authentication scope' exactly is: scope String representing the authentication scope.

• Flat File Connection Manager in SSIS package shows "Valid File Name Must be Selected"

  - by Traples

  (Flat File Location) Samba Share | Windows Share (SSIS) _______________________________ | | XP 32bit | Works | Works | | 2003 Serv 32bit | Works | Works | | Vista 64bit | ERROR | Works | | Win 7 64bit | ERROR | Works | | 2008 Serv 64bit | ERROR | Works I created an SSIS package in VS 2008 that parses a flat file from a shared folder and puts the records into a SQL Server db. I recently installed Windows 7 and VS 2008 on a new workstation. When I import the package from TFS and open it, I get the error Validation error. Parse and Import Catalog Flat File: MySSISPackage: The file name "\\shared\flatfile.txt" specified in the connection was not valid. When I open the Flat File Connection Manager Editor, there is an error stating: A valid file name must be selected I can browse to and select the file from inside the editor, but I cannot change any properties, or move away from the General tab because of this error. If I go back to my laptop (Windows XP), where the package was first created, there is no error. Both workstations are on the same domain, and I'm logging in using the same credentials. Any ideas as to why I would receive this error from one workstation and not another? UPDATE: If I take the .dtsx package from the running workstation and load it into SSIS on the server, I get the following errors when it tries to run: Error: The file name "\\shared\flatfile.txt" specified in the connection was not valid. and... Error: Connection "MySSISPackage" failed validation. and... Error: The file name property is not valid. The file name is a device or contains invalid characters. UPDATE 2: a) The Shared folder I'm trying to pull the flat file from is a Samba share on a Unix box. b) If I access the file using SSIS on any 64-bit platform (Windows 7 64-bit, Vista 64-bit, Windows Server 2008) I get the error "A valid file name must be selected." c) Accessing the file using SSIS from 32-bit environments (Windows XP 32-bit, Windows Server 2003 32-bit) there is no problem. d) If I move the file to a shared folder on a Windows server, 64-bit SSIS recognizes the file.

• [android] How to center buttons on screen horizontally and vertically plus equidistant apart?

  - by marc

  I've been racking my brain (android newbie here, so not hard to do) for awhile trying to figure out how to accomplish this: Desired Layout using a RelativeLayout or something other than AbsoluteLayout which is what this was created with. I'm coming from a Windows programming background where the device adjusts the 'absolute' positioning for you and GUI layout was a non-issue. The first layout works great in the emulator, but doesn't format for my Nexus One or any other screen that differs from the emulator size. I expected this because it's absolutely positioned, but haven't found a solution that will format correctly for different screen sizes. My goal is to have the layout work for different screen sizes and in portrait / landscape. Here's the Code that I'm currently using: [main.xml] <?xml version="1.0" encoding="utf-8"?> <AbsoluteLayout android:layout_width="fill_parent" android:layout_height="fill_parent" xmlns:android="http://schemas.android.com/apk/res/android" > <Button android:id="@+id/Button01" android:layout_width="188px" android:layout_height="100px" android:text="A" android:layout_y="50px" android:layout_x="65px" android:textSize="48sp"/> <Button android:id="@+id/Button02" android:layout_width="188px" android:layout_height="100px" android:text="B" android:layout_y="175px" android:layout_x="65px" android:textSize="48sp"/> <Button android:id="@+id/Button03" android:layout_width="188px" android:layout_height="100px" android:text="C" android:layout_y="300px" android:layout_x="65px" android:textSize="48sp"/> </AbsoluteLayout> Using tidbits from other questions here, I came up with this, it’s closer, but not there yet. <?xml version="1.0" encoding="utf-8"?> <TableLayout android:gravity="center" android:id="@+id/widget49" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical" xmlns:android="http://schemas.android.com/apk/res/android" > <Button android:id="@+id/Button01" android:layout_width="0dip" android:layout_weight="1" android:text="A" android:textSize="48sp"/> <Button android:id="@+id/Button02" android:layout_width="0dip" android:layout_weight="1" android:text="B" android:textSize="48sp"/> <Button android:id="@+id/Button03" android:layout_width="0dip" android:layout_weight="1" android:text="C" android:textSize="48sp"/> </TableLayout> Here’s a picture of the TableLayout: Another Attempt Any help / guidance would be greatly appreciated.

• [C#] Convert string to double with 2 digit after decimal separator

  - by st.stoqnov

  All began with these simple lines of code: string s = "16.9"; double d = Convert.ToDouble(s); d*=100; The result should be 1690.0, but it's not. d is equal to 1689.9999999999998. All I want to do is to round a double to value with 2 digit after decimal separator. Here is my function. private double RoundFloat(double Value) { float sign = (Value < 0) ? -0.01f : 0.01f; if (Math.Abs(Value) < 0.00001) Value = 0; string SVal = Value.ToString(); string DecimalSeparator = System.Globalization.CultureInfo.CurrentCulture.NumberFormat.CurrencyDecimalSeparator; int i = SVal.IndexOf(DecimalSeparator); if (i > 0) { int SRnd; try { // ????? ??????? ????? ???? ?????????? ?????????? SRnd = Convert.ToInt32(SVal.Substring(i + 3, 1)); } catch { SRnd = 0; } if (SVal.Length > i + 3) SVal = SVal.Substring(0, i + 3); //SVal += "00001"; try { double result = (SRnd >= 5) ? Convert.ToDouble(SVal) + sign : Convert.ToDouble(SVal); //result = Math.Round(result, 2); return result; } catch { return 0; } } else { return Value; } But again the same problem, converting from string to double is not working as I want. A workaround to this problem is to concatenate "00001" to the string and then use the Math.Round function (commented in the example above). This double value multiplied to 100 (as integer) is send to a device (cash register) and this values must be correct. I am using VS2005 + .NET CF 2.0 Is there another more "elegant" solution, I am not happy with this one.

• iPad application crash in Apple review - cannot replicate in simulator, have crash log

  - by Mike

  I am clearly missing something obvious here and would really appreciate some input. I have tried repeatedly to submit an application to Apple (iPad in this case) that is crashing on their end when testing but I cannot replicated the situation on my end (obviously I only have the damned simulator to work with at this point). The crash log is as follows: Date/Time: 2010-04-01 05:39:47.226 -0700 OS Version: iPhone OS 3.2 (7B367) Report Version: 104 Exception Type: EXC_CRASH (SIGABRT) Exception Codes: 0x00000000, 0x00000000 Crashed Thread: 0 Thread 0 Crashed: 0 libSystem.B.dylib 0x000790a0 __kill + 8 1 libSystem.B.dylib 0x00079090 kill + 4 2 libSystem.B.dylib 0x00079082 raise + 10 3 libSystem.B.dylib 0x0008d20a abort + 50 4 libstdc++.6.dylib 0x00044a1c __gnu_cxx::__verbose_terminate_handler() + 376 5 libobjc.A.dylib 0x000057c4 _objc_terminate + 104 6 libstdc++.6.dylib 0x00042dee __cxxabiv1::__terminate(void (*)()) + 46 7 libstdc++.6.dylib 0x00042e42 std::terminate() + 10 8 libstdc++.6.dylib 0x00042f12 __cxa_throw + 78 9 libobjc.A.dylib 0x000046a4 objc_exception_throw + 64 10 CoreFoundation 0x00090c6e +[NSException raise:format:arguments:] + 74 11 CoreFoundation 0x00090d38 +[NSException raise:format:] + 28 12 Foundation 0x00002600 -[NSCFDictionary setObject:forKey:] + 184 13 iPadMosaic 0x00003282 -[iPadMosaicViewController getAlbumThumbs] (iPadMosaicViewController.m:468) 14 Foundation 0x000728fe __NSFireDelayedPerform + 314 15 CoreFoundation 0x00022d1c CFRunLoopRunSpecific + 2092 16 CoreFoundation 0x000224da CFRunLoopRunInMode + 42 17 GraphicsServices 0x000030d4 GSEventRunModal + 108 18 GraphicsServices 0x00003180 GSEventRun + 56 19 UIKit 0x000034c2 -[UIApplication _run] + 374 20 UIKit 0x000019ec UIApplicationMain + 636 21 iPadMosaic 0x00002234 main (main.m:14) 22 iPadMosaic 0x00002204 start + 32 My understanding here is that I am botching the Dictionary add somehow. The relevant lines of code are: for (NSDictionary *album in self.albumList) { // Get image for each album cover UIImage *albumCover; // Loop through photos to get URL of cover based on photo ID match NSString *coverURL = @""; for (NSDictionary *photo in self.photoList) { if ([[photo objectForKey:@"pid"] isEqualToString:[album objectForKey:@"cover_pid"]]) { coverURL = [photo objectForKey:@"src"]; } } NSURL *albumCoverURL = [NSURL URLWithString:coverURL]; NSData *albumCoverData = [NSData dataWithContentsOfURL:albumCoverURL]; albumCover = [UIImage imageWithData:albumCoverData]; if (albumCover == nil || albumCover == NULL) { //NSLog(@"No album cover for some reason"); albumCover = [UIImage imageNamed:@"noImage.png"]; } [[self.albumList objectAtIndex:albumCurrent] setObject:albumCover forKey:@"coverThumb"]; } This is part of a loop that runs over the existing dictionaries stored in an array. If retrieving the album cover fails for some reason the object is filled with a default image and then added. The last line of the code is what's showing up in the crash log. It runs fine in the simulator but crashes 100% in testing on device apparently. Can anyone tell me what I am missing here?

• Sorting Android ListView

  - by aeoth

  I'm only starting with Android dev, and while the Milestone is a nice device Java is not my natural language and I'm struggling with both the Google docs on Android SDK, Eclipse and Java itself. Anyway... I'm writing a microblog client for Android to go along with my Windows client (MahTweets). At the moment I've got Tweets coming and going without fail, the problem is with the UI. The initial call will order items correctly (as in highest to lowest) 3 2 1 When a refresh is made 3 2 1 6 5 4 After the tweets are processed, I'm calling adapter.notifyDataSetChanged(); Initially I thought that getItem() on the Adapter needed to be sorted (and the code below is what I ended up with), but I'm still not having any luck. public class TweetAdapter extends BaseAdapter { private List<IStatusUpdate> elements; private Context c; public TweetAdapter(Context c, List<IStatusUpdate> Tweets) { this.elements = Tweets; this.c = c; } public int getCount() { return elements.size(); } public Object getItem(int position) { Collections.sort(elements, new IStatusUpdateComparator()); return elements.get(position); } public long getItemId(int id) { return id; } public void Remove(int id) { notifyDataSetChanged(); } public View getView(int position, View convertView, ViewGroup parent) { RelativeLayout rowLayout; IStatusUpdate t = elements.get(position); rowLayout = t.GetParent().GetUI(t, parent, c); return rowLayout; } class IStatusUpdateComparator implements Comparator { public int compare(Object obj1, Object obj2) { IStatusUpdate update1 = (IStatusUpdate)obj1; IStatusUpdate update2 = (IStatusUpdate)obj2; int result = update1.getID().compareTo(update2.getID()); if (result == -1) return 1; else if (result == 1) return 0; return result; } } } Is there a better way to go about sorting ListViews in Android, while still being able to use the LayoutInflater? (rowLayout = t.GetParent().GetUI(t, parent, c) expands the UI to the specific view which the microblog implementation can provide)

• Android: OutofMemoryError: bitmap size exceeds VM budget with no reason I can see.

  - by Meymann

  Hi. I am having an OutOfMemory exception with a gallery over 600x800 pixels JPEG's. The environment I've been using Gallery with JPG images around 600x800 pixels. Since my content may be a bit more complex than just images, I have set each view to be a RelativeLayout that wraps ImageView with the JPG. In order to "speed up" the user experience I have a simple cache of 4 slots that prefetches (in a looper) about 1 image left and 1 image right to the displayed image and keeps them in a 4 slot HashMap. The platform I am using AVD of 256 RAM and 128 Heap Size, with a 600x800 screen. It also happens on an Entourage Edge target, except that with the device it's harder to debug. The problem I have been getting an exception: OutofMemoryError: bitmap size exceeds VM budget And it happens when fetching the fifth image. I have tried to change the size of my image cache, and it is still the same. The strange thing: There should not be a memory problem In order to make sure the heap limit is very far away from what I need, I have defined a dummy 8MB array in the beginning, and left it unreferenced so it's immediately dispatched. It is a member of the activity thread and is defined as following static { @SuppressWarnings("unused") byte dummy[] = new byte[ 8*1024*1024 ]; } The result is that the heap size is nearly 11MB and it's all free. Note I have added that trick after it began to crash. It makes OutOfMemory less frequent. Now, I am using DDMS. Just before the crash (does not change much after the crash), DDMS shows: ID Heap Size Allocated Free %Used #Objects 1 11.195 MB 2.428 MB 8.767 MB 21.69% 47,156 And in the detail table it shows: Type Count Total Size Smallest Largest Median Average free 1,536 8.739MB 16B 7.750MB 24B 5.825KB The largest block is 7.7MB. And yet the LogCat says: ERROR/dalvikvm-heap(1923): 925200-byte external allocation too large for this process. If you mind the relation of the median and the average, it is plausible to assume that most of the available blocks are very small. However, there is a block large enough for the bitmap, it's 7.7M. How come it is still not enough? Note: I recorded a heap trace. When looking at the amount of data allocated, it does not feel like more than 2M is allocated. It does match the free memory report by DDMS. Could it be that I experience some problem like heap-fragmentation? How do I solve/workaround the problem? Is the heap shared to all threads? Could it be that I interpret the DDMS readout in a wrong way, and there is really no 900K block to allocate? If so, can anybody please tell me where I can see that? Thanks a lot Meymann

• UIScrollView image/photo viewer with paging enabled and zooming

  - by Mike Weller

  OK, I think it's time to make an official place on the internet for this problem: How to make a UIScrollView photoviewer with paging and zooming. Welcome my fellow UIScrollView hackers. I have a UIScrollView with paging enabled, and I'm displaying UIImageViews like the built-in photos app. (Does this sound familiar yet?) I found the following project on github: http://wiki.github.com/andreyvit/ScrollingMadness Which shows how to implement zooming in a scroll view while paging is enabled. If anyone else tries this out, I actually had to remove the UIScrollView subclass and use the native class otherwise it doesn't work. I think it's because of changes in the 3.0 SDK relating to how the scroll view intercepts touch events. So the the idea is to remove all the other views when you start zooming, and move the current view to (0, 0) in the scrollview, updating the contentsize etc. Then when you zoom back to 1.0f it adds the other views back and puts things all back in order. Anyway, that project works perfectly in the simulator, but on the device there is some nasty movement of the view you are resizing, which looks like it's caused by the fact we are changing the contentsize/offset etc. for the view being resized. You have to do this view moving otherwise you can pan left through the whitespace left by the other views. I found one interesting note in the "Known Issues" of the 3.0 SDK release notes: UIScrollView: After zooming, content inset is ignored and content is left in the wrong position. This kind of sounds like what is happening here. After zooming in, the view will shift offscreen because you have changed the offset etc. I've spent hours on this already and I'm slowing coming to the sad realization that this just isn't going to work. Three20's photo viewer is out of the question: it's too heavy weight and there is too much unnecessary UI and other behaviour. The built in Photo app seems to do some magic. If you zoom in on an image and pan to the far edges, the current photo moves independently of the photo next to it which isn't what you get when trying this with a standard UIScrollView. I've seen discussion about nesting the UIScrollView's but I really don't want to go there. Has anybody managed this with the standard UIScrollView (and works in the 2.2 and 3.0 SDK)? I don't fancy rolling my own zoom + bounce + pan + paging code.

• Android Packaging Problem: resources.ap_ does not exist

  - by Galip

  I am trying to fix a problem in Eclipse for like 3 hours and I haven't made any progress. Tomorrow is the customer coming to look at my app, and I have no time left. This is really frustrating! This morning when I was coding and I wanted to run my app on my device Eclipse crashed all of a sudden. 'aapt.exe has stopped working' After this Eclipse wasn't starting anymore. It froze at the splash image. I looked on the internet and tried different solutions like going back to Java SE 6 update 20, changing .ini file etc. in the end reinstalling Eclipse did the job. Shortly after that the 'aapt.exe has stopped working' returned. I found a solution by changing my projects target. 1.5, 1.6, 2.2 doesn't matter, as long as it's different than the one before. Now I get the Error generating final archive: java.io.FileNotFoundException: C:\xxx\bin\resources.ap_ does not exist error. I tried clean but that doesn't work. Deleting and automatically regenarting R.java also didn't work. I ran the same code in Netbeans with the Android plugin and there it gives me the 'aapt.exe has stopped working' again :( Please guys, how can I fix this? Edit: I think I may have found the reason. These are the error lines in the console: org.xmlpull.v1.XmlPullParserException: Binary XML file line #3: <bitmap> requires a valid src attribute at android.graphics.drawable.BitmapDrawable.inflate(BitmapDrawable.java:341) at android.graphics.drawable.Drawable.createFromXmlInner(Drawable.java:779) at android.graphics.drawable.Drawable.createFromXml(Drawable.java:720) at com.android.layoutlib.bridge.ResourceHelper.getDrawable(ResourceHelper.java:150) at com.android.layoutlib.bridge.BridgeTypedArray.getDrawable(BridgeTypedArray.java:668) at android.view.View.<init>(View.java:1846) at android.view.View.<init>(View.java:1795) at android.view.ViewGroup.<init>(ViewGroup.java:282) at java.lang.reflect.Method.invoke(Unknown Source) at org.eclipse.equinox.launcher.Main.invokeFramework(Main.java:619) at org.eclipse.equinox.launcher.Main.basicRun(Main.java:574) at org.eclipse.equinox.launcher.Main.run(Main.java:1407) at org.eclipse.equinox.launcher.Main.main(Main.java:1383) [2011-01-17 16:37:20 - gegevens.xml] Unable to resolve drawable "com.android.layoutlib.utils.ResourceValue@267e33de" in attribute "background" The file it's talking about is 'bg.png'.

• Android "Trying to use recycled bitmap" error?

  - by Mike

  Hi all, I am running into a problem with bitmaps on an Android application I am working on. What is suppose to happen is that the application downloads images from a website, saves them to the device, loads them into memory as bitmaps into an arraylist, and displays them to the user. This all works fine when the application is first started. However, I have added a refresh option for the user where the images are deleted, and the process outlined above starts all over. My problem: By using the refresh option the old images were still in memory and I would quickly get OutOfMemoryErrors. Thus, if the images are being refreshed, I had it run through the arraylist and recycle the old images. However, when the application goes to load the new images into the arraylist, it crashes with a "Trying to use recycled bitmap" error. As far as I understand it, recycling a bitmap destroys the bitmap and frees up its memory for other objects. If I want to use the bitmap again, it has to be reinitialized. I believe that I am doing this when the new files are loaded into the arraylist, but something is still wrong. Any help is greatly appreciated as this is very frustrating. The problem code is below. Thank you! public void fillUI(final int refresh) { // Recycle the images to avoid memory leaks if(refresh==1) { for(int x=0; x<images.size(); x++) images.get(x).recycle(); images.clear(); selImage=-1; // Reset the selected image variable } final ProgressDialog progressDialog = ProgressDialog.show(this, null, this.getString(R.string.loadingImages)); // Create the array with the image bitmaps in it new Thread(new Runnable() { public void run() { Looper.prepare(); File[] fileList = new File("/data/data/[package name]/files/").listFiles(); if(fileList!=null) { for(int x=0; x<fileList.length; x++) { try { images.add(BitmapFactory.decodeFile("/data/data/[package name]/files/" + fileList[x].getName())); } catch (OutOfMemoryError ome) { Log.i(LOG_FILE, "out of memory again :("); } } Collections.reverse(images); } fillUiHandler.sendEmptyMessage(0); } }).start(); fillUiHandler = new Handler() { public void handleMessage(Message msg) { progressDialog.dismiss(); } }; }

• Android Mediaplayer: setDataSource issue for downloaded media file

  - by Erik

  I have an application that will record and play audio files. Some of the audio files are downloaded using simple standard http downloads using httpclient. It worked like a charm for a long time. Now all of a sudden I cannot play the files I download. It fails with this stack. I store the files on the SDCard and I experience the problem both on a handset and a USB connected device. I have checked that the downloaded file is cool on the server, and I can play it without any issues. These are the code snippets I use ( I know that recordingFile is a valid path for the file). // inside the activity class private void playRecording() throws IOException{ File recordingFile = new File(recordingFileName); FileInputStream recordingInputStream = new FileInputStream(recordingFile); audioMediaPlayer.playAudio(recordingInputStream); } Here is the media player code: // inside my media player class which handles the recordings public void playAudio(FileInputStream audioInputStream) throws IOException { mediaPlayer.reset(); mediaPlayer.setDataSource(audioInputStream.getFD()); mediaPlayer.prepare(); mediaPlayer.start(); } Here is the exception: E/MediaPlayerService( 555): offset error E/MediaPlayer( 786): Unable to to create media player W/System.err( 786): java.io.IOException: setDataSourceFD failed.: status=0x80000000 W/System.err( 786): at android.media.MediaPlayer.setDataSource(Native Method) W/System.err( 786): at android.media.MediaPlayer.setDataSource(MediaPlayer.java:632) W/System.err( 786): at net.xxx.xxx.AudioMediaPlayer.playAudio(AudioMediaPlayer.java:69) W/System.err( 786): at net.xxx.xxx.Downloads.playRecording(Downloads.java:299) W/System.err( 786): at net.xxx.xxx.Downloads.access$0(Downloads.java:294) W/System.err( 786): at net.xxx.xxx.Downloads$1.onClick(Downloads.java:135) I have tried seeking some answer of the offset error, but not really clear what this issue might be.

• WIA Automation for scanner color intent is not working

  - by Mike Nicholson

  I cannot get my Canon Pixma MP150 to scan a color scan from c# code. The following code is resulting in a black and white image, or if I change the value of 6146 to 2 then a grayscale image is created. I would like to be able to have a color scan from code. I know the scanner does color images because I can do one through the xp wizard in "scanners and camera". Can anyone help me figure out what value I am not setting for a color scan. All documentation and examples I can find just say to change the value of 6146.

• GameKit: GKSession manual

  - by mongeta

  Hello, I want to connect two devices using the GKSession, starting one as a server and the other one as a client. Using this configuration I can't use the GKPeerPickerController. I'm having problems for connecting the two devices: Using only bluetooth: impossible using WiFi: at least there are some data exchange between the devices but no successfully conection. In the interface file I have the GKSessionDelegate GKSession *session; In the implementation, I start the server using this code: session = [[GKSession alloc] initWithSessionID:@"iFood" displayName:nil sessionMode:GKSessionModeClient]; session.delegate = self; session.available = YES; The client starts using this code: session = [[GKSession alloc] initWithSessionID:@"iFood" displayName:nil sessionMode:GKSessionModeServer]; session.delegate = self; session.available = YES; How I can force the use of Bluetooth instead of the WiFi ? Also I have implemented those calls: -(void)session:(GKSession *)session didReceiveConnectionRequestFromPeer:(NSString *)peerID { NSLog(@"Someone is trying to connect"); } - (BOOL)acceptConnectionFromPeer:(NSString *)peerID error:(NSError **)error { NSLog(@"acceptConnectionFromPeer"); } When I start, I get this into the debugger: Listening on port 50775 2010-02-19 14:55:02.547 iFood[3009:5103] handleEvents started (2) And when the other device starts to find, I get this: ~ DNSServiceBrowse callback: Ref=187f70, Flags=2, IFIndex=2 (name=[en0]), ErrorType=0 name=00eGs1R1A..Only by Audi regtype=_2c3mugr67ej6j7._udp. domain=local. ~ DNSServiceQueryRecord callback: Ref=17bd40, Flags=2, IFIndex=2 (name=[en0]), ErrorType=0 fullname=00eGs1R1A\.\.Only\032by\032Audi._2c3mugr67ej6j7._udp.local. rrtype=16 rrclass=1 rdlen=18 ttl=4500 ** peer 1527211048: oldbusy=0, newbusy=0 ~ DNSServiceBrowse callback: Ref=187f70, Flags=2, IFIndex=-3 (name=[]), ErrorType=0 name=00eGs1R1A..Only by Audi regtype=_2c3mugr67ej6j7._udp. domain=local.

• SSLException: Keystore does not support enabled cipher suites

  - by wurfkeks

  I want to implement a small android application, that works as SSL Server. After lot of problems with the right format of the keystore, I solved this and run into the next one. My keystore file is properly loaded by the KeyStore class. But when I try to open the server socket (socket.accept()) the following error is raised: javax.net.ssl.SSLException: Could not find any key store entries to support the enabled cipher suites. I generated my keystore with this command: keytool -genkey -keystore test.keystore -keyalg RSA -keypass ssltest -storepass ssltest -storetype BKS -provider org.bouncycastle.jce.provider.BouncyCastleProvider -providerpath bcprov.jar with the Unlimited Strength Jurisdiction Policy for Java SE6 applied to my jre6. I got a list of supported ciphers suites by calling socket.getSupportedCipherSuites() that prints a long list with very different combinations. But I don't know how to get a supported key. I also tried the android debug keystore after converting it to BKS format using portecle but get still the same error. Can anyone help and tell how I can generate a key that is compatible with one of the cipher suites? Version Information: targetSDK: 15 tested on emulator running 4.0.3 and real device running 2.3.3 BounceCastle 1.46 portecle 1.7 Code of my test application: public class SSLTestActivity extends Activity implements Runnable { SSLServerSocket mServerSocket; ToggleButton tglBtn; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); this.tglBtn = (ToggleButton)findViewById(R.id.toggleButton1); tglBtn.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() { @Override public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) { if (isChecked) { new Thread(SSLTestActivity.this).run(); } else { try { if (mServerSocket != null) mServerSocket.close(); } catch (IOException e) { Log.e("SSLTestActivity", e.toString()); } } } }); } @Override public void run() { try { KeyStore keyStore = KeyStore.getInstance(KeyStore.getDefaultType()); keyStore.load(getAssets().open("test.keystore"), "ssltest".toCharArray()); ServerSocketFactory socketFactory = SSLServerSocketFactory.getDefault(); mServerSocket = (SSLServerSocket) socketFactory.createServerSocket(8080); while (!mServerSocket.isClosed()) { Socket client = mServerSocket.accept(); PrintWriter output = new PrintWriter(client.getOutputStream(), true); output.println("So long, and thanks for all the fish!"); client.close(); } } catch (Exception e) { Log.e("SSLTestActivity", e.toString()); } } }

• availability of Win32_MountPoint and Win32_Volume on Windows XP?

  - by SteveC

  From the MSDN articles I've found -- http://msdn.microsoft.com/en-us/library/aa394515(v=VS.85).aspx -- Win32_Volume and Win32_MountPoint aren't available on Windows XP. However, I'm developing a C# app on Windows XP (64bit), and I can get to those WMI classes just fine. Users of my app will be on Windows XP sp2 with .Net 3.5 sp1. Googling around, I can't determine whether I can count on this or not. Am I successful on my system because of one or more of the following: - windows xp service pack 2? - visual studio 2008 sp1 was installed? - .Net 3.5 sp1? Should I use something other than WMI to get at the volume/mountpoint info? Below is sample code that's working... public static Dictionary<string, NameValueCollection> GetAllVolumeDeviceIDs() { Dictionary<string, NameValueCollection> ret = new Dictionary<string, NameValueCollection>(); // retrieve information from Win32_Volume try { using (ManagementClass volClass = new ManagementClass("Win32_Volume")) { using (ManagementObjectCollection mocVols = volClass.GetInstances()) { // iterate over every volume foreach (ManagementObject moVol in mocVols) { // get the volume's device ID (will be key into our dictionary) string devId = moVol.GetPropertyValue("DeviceID").ToString(); ret.Add(devId, new NameValueCollection()); //Console.WriteLine("Vol: {0}", devId); // for each non-null property on the Volume, add it to our NameValueCollection foreach (PropertyData p in moVol.Properties) { if (p.Value == null) continue; ret[devId].Add(p.Name, p.Value.ToString()); //Console.WriteLine("\t{0}: {1}", p.Name, p.Value); } // find the mountpoints of this volume using (ManagementObjectCollection mocMPs = moVol.GetRelationships("Win32_MountPoint")) { foreach (ManagementObject moMP in mocMPs) { // only care about adding directory // Directory prop will be something like "Win32_Directory.Name=\"C:\\\\\"" string dir = moMP["Directory"].ToString(); // find opening/closing quotes in order to get the substring we want int first = dir.IndexOf('"') + 1; int last = dir.LastIndexOf('"'); string dirSubstr = dir.Substring(first , last - first); // use GetFullPath to normalize/unescape any extra backslashes string fullpath = Path.GetFullPath(dirSubstr); ret[devId].Add(MOUNTPOINT_DIRS_KEY, fullpath); } } } } } } catch (Exception ex) { Console.WriteLine("Problem retrieving Volume information from WMI. {0} - \n{1}",ex.Message,ex.StackTrace); return ret; } return ret; }
