  • Android Create Layered drawable in XML

    - by Lyubomyr Dutko
    Hello, I would like to create a drawable in XML that should include: image drawable color drawable The color drawable provides white transparent color. So, as a result we would have image with some white transparent layer on top. I have tried to use LayerDrawable, but it fails to be created during application launch: <LayerDrawable xmlns:android="http://schemas.android.com/apk/res/android"> <BitmapDrawable android:src="@drawable/button_play" /> <ColorDrawable android:color="#80FFFFFF"/> </LayerDrawable> Could you please advice what is wrong here?

  • How to install and use db4o for Android?

    - by Viet
    I have to admit that I'm new to Java and Android. db4o seems to be an excellent DB framework to replace SQLite http://developer.db4o.com/Platforms/Java/Android.aspx. I want to use it for my Android application. I don't know how to: Import/Install/Attach/Upload db4o to Android phone. Where should I put the JAR file db4o-7.12.132.14217-all-java5.jar so that it was uploaded to Android phone and it could be called from the application? Please kindly advise! Many thanks!!!

  • Instrumentation class in the Android API.

    - by Riyas
    Hi All, I have question on the Android API. Android API provides a class called "Instrumentation" class. What is the use of this class? Is the Instrumentation class be used only together with Junit for unit testing. Can Junit framework can be used to test the methods of the Android API without using the Instrumentation class. Since Junit package has been included in the Android package, I hope we dont need to use install separately for unit testing. I would appreciate if you could provide me the information as i can't find these clear information anywhere on the Web. If we use Junit test framework to test the Android API, can we have test results in the UI format rather than test format.? Thanks a lot. Apprecite your time. Regards, Riyas

  • Where is the Android Metamodel located?

    - by Dominik
    Hey, I would like to use Android for Model-Driven-Software-Development. For this, I need to locate the Android Model in the SDK. I already searched a while for it, but were not able to find it. Has anyone an idea where it could be? Is it possible, that it is the AndroidManifest.xml-File in the folder android-sdk-\platforms\android-x\android.jar? After unpacking this file, I am not able to open that file correctly on Windows XP, because a lot of characters have the wrong character set. Or is it also possible, that it is only located in the source code? Thanks in advance, Dominik

  • Changing API level Android Studio

    - by James B
    I want to change the minimum SDK version in Android Studio from API 12 to API 14. I have tried changing it in the manifest file, i.e., <uses-sdk android:minSdkVersion="14" android:targetSdkVersion="18" /> and rebuilding the project, but I still get the Android Studio IDE throwing up some errors. I presume I have to set the min SDK in 'project properties' or something similar so the IDE recognises the change, but I can't find where this is done in Android Studio. Pointers greatly appreciated. Thnx.

  • Interaction between Java and Android

    - by Grasper
    I am currently trying to research how to use Android with an existing java based system. Basically, I need to communicate to/from an Android application. The system currently passes object data from computer to computer using ActiveMQ as the JMS provider. On one of the computers is a display which shows object data to the user. What we want to do now is use a phone (running Android) as another option to show this object data to a user with wifi/network access. Ideally we would like to have a native application on the Android that would listen to the ActiveMQ topic and publish to another Topic and read/write/display the object data, but from some research I have done, I am not sure if this is possible. What are some other ways to approach this problem? The android Phone needs to be able to send/receive data. I have been using the AndroidEmulator for testing.

  • what's the story with the android XML namespace?

    - by Peter vdL
    When you first use a name from the android XML namespace, you have to say where to find it, with an attribute in XML like this: <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" However, that URL is a 404 - nothing found there. The android: namespace is actually included under the locally-installed SDK. So what's going on here? Why do I need to include a dead URL? Why doesn't the build system pick it up from the SDK like all the other libraries? Thanks, just looking for the back story on this. Peter

  • Android: making a custom ListView independent of adapters ?

    - by wei
    I am adding a local database as a cache to a remote web service in my android application to answer queries. I used ArrayAdapters before for list views to display the results from the web service. Now with a database cache, the result could be either a Cursor(from database) or a List(from web), which means the adapter can be CursorAdapter or ArrayAdapter too. Creating two adapters for one query doesn't seem to be a good idea. So I am wondering what would be the best way to refactor my current code to add this database feature? Thanks,

  • Android Source code download error

    - by user351850
    Hi all I have followed the instructions on the Android website on how to download the latest android source code files but it gives errors when i run this command: repo init -u git://android2.git.kernel.org/platform/manifest.git It gives the following error: Getting repo ... from git://android.git.kernel.org/tools/repo.git android.git.kernel.org[0: 199.6.1.176]: errno=Connection refused android.git.kernel.org[0: 130.239.17.12]: errno=Connection refused fatal: unable to connect a socket (Connection refused) On checking forums for its resolution, i was told that port 9418 was being blocked. I use Ubuntu 10.04 and ensured that the firewall wasnt blocking the port and also enabled the port and the above IP addresses. I also spoke to the networking peeps who ensured that no traffic from the internet is being blocked. I would be glad if i could get directions on how to proceed next. Many thanks as you respond.

  • SpeechRecognizer causes ANR... I need help with Android speech API.

    - by Dondo Chaka
    I'm trying to use Android's speech recognition package to record user speech and translate it to text. Unfortunately, when I attempt initiate listening, I get an ANR error that doesn't point to anything specific. As the SpeechRecognizer API indicates, a RuntimeException is thrown if you attempt to call it from the main thread. This would make me wonder if the processing was just too demanding... but I know that other applications use the Android API for this purpose and it is typically pretty snappy. java.lang.RuntimeException: SpeechRecognizer should be used only from the application's main thread Here is a (trimmed) sample of the code I'm trying to call from my service. Is this the proper approach? Thanks for taking the time to help. This has been a hurdle I haven't been able to get over yet. Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH); intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, RecognizerIntent.LANGUAGE_MODEL_FREE_FORM); intent.putExtra(RecognizerIntent.EXTRA_CALLING_PACKAGE, "com.domain.app"); SpeechRecognizer recognizer = SpeechRecognizer .createSpeechRecognizer(this.getApplicationContext()); RecognitionListener listener = new RecognitionListener() { @Override public void onResults(Bundle results) { ArrayList<String> voiceResults = results .getStringArrayList(RecognizerIntent.EXTRA_RESULTS); if (voiceResults == null) { Log.e(getString(R.string.log_label), "No voice results"); } else { Log.d(getString(R.string.log_label), "Printing matches: "); for (String match : voiceResults) { Log.d(getString(R.string.log_label), match); } } } @Override public void onReadyForSpeech(Bundle params) { Log.d(getString(R.string.log_label), "Ready for speech"); } @Override public void onError(int error) { Log.d(getString(R.string.log_label), "Error listening for speech: " + error); } @Override public void onBeginningOfSpeech() { Log.d(getString(R.string.log_label), "Speech starting"); } }; recognizer.setRecognitionListener(listener); recognizer.startListening(intent);

  • Android - doInBackground() error in AsyncTask

    - by AimanB
    What my app here basically does is it captures a photo or import from gallery, and when the Upload button is pressed, the image will be uploaded to a localhost server. Before I implemented AsyncTask into the process, it doesn't have any problem uploading whatsoever. Now that I've put AsyncTask, everything went wrong. I don't know which part that I do wrong in this phase. This is what logcat shows when I try to upload an image file: 10-28 17:23:25.989: E/AndroidRuntime(3356): FATAL EXCEPTION: AsyncTask #5 10-28 17:23:25.989: E/AndroidRuntime(3356): java.lang.RuntimeException: An error occured while executing doInBackground() 10-28 17:23:25.989: E/AndroidRuntime(3356): at android.os.AsyncTask$3.done(AsyncTask.java:299) 10-28 17:23:25.989: E/AndroidRuntime(3356): at java.util.concurrent.FutureTask.finishCompletion(FutureTask.java:352) 10-28 17:23:25.989: E/AndroidRuntime(3356): at java.util.concurrent.FutureTask.setException(FutureTask.java:219) 10-28 17:23:25.989: E/AndroidRuntime(3356): at java.util.concurrent.FutureTask.run(FutureTask.java:239) 10-28 17:23:25.989: E/AndroidRuntime(3356): at android.os.AsyncTask$SerialExecutor$1.run(AsyncTask.java:230) 10-28 17:23:25.989: E/AndroidRuntime(3356): at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1080) 10-28 17:23:25.989: E/AndroidRuntime(3356): at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:573) 10-28 17:23:25.989: E/AndroidRuntime(3356): at java.lang.Thread.run(Thread.java:856) 10-28 17:23:25.989: E/AndroidRuntime(3356): Caused by: java.lang.RuntimeException: Can't create handler inside thread that has not called Looper.prepare() 10-28 17:23:25.989: E/AndroidRuntime(3356): at android.os.Handler.<init>(Handler.java:197) 10-28 17:23:25.989: E/AndroidRuntime(3356): at android.os.Handler.<init>(Handler.java:111) 10-28 17:23:25.989: E/AndroidRuntime(3356): at android.widget.Toast$TN.<init>(Toast.java:324) 10-28 17:23:25.989: E/AndroidRuntime(3356): at android.widget.Toast.<init>(Toast.java:91) 10-28 17:23:25.989: E/AndroidRuntime(3356): at android.widget.Toast.makeText(Toast.java:238) 10-28 17:23:25.989: E/AndroidRuntime(3356): at com.aiman.webshopper.UploadImageActivity$1execMultiPostAsync.doInBackground(UploadImageActivity.java:268) 10-28 17:23:25.989: E/AndroidRuntime(3356): at com.aiman.webshopper.UploadImageActivity$1execMultiPostAsync.doInBackground(UploadImageActivity.java:1) 10-28 17:23:25.989: E/AndroidRuntime(3356): at android.os.AsyncTask$2.call(AsyncTask.java:287) 10-28 17:23:25.989: E/AndroidRuntime(3356): at java.util.concurrent.FutureTask.run(FutureTask.java:234) This is my code for the Upload activity: public class UploadImageActivity extends Activity implements OnItemSelectedListener { InputStream inputStream;

I think I've made a mistake somewhere.

  • 5 Ways Android Still Disappoints (Me)

    - by TStewartDev
    Let me make this clear: I'm annoyed with Apple. I don't like their current policies and I don't like where Steve Jobs is taking the company. In general, I don't like it when any one company gets too much control in a market. When that happens, the leading company dictates the game and as consumers, our options all but disappear. That said, I'm still going to buy a new iPhone next week. My Apple-hating friends seem to desperately want me to go Android instead, but frankly, it's not good enough for me, and here are the reasons why. The Modern WinMo One of the reasons that Microsoft has identified for Windows Mobile's rapid decline is the breadth of hardware. They exercised little control over manufacturer's implementations. In theory, that sounds great. We as consumers have lots of choice. In practice, though, it meant among other things that updates to the devices were left up to the manufacturers. As a result, that rarely happened. (I'm still bitter at Toshiba for leaving me hanging back in 2002.) And now, Google is doing the same thing with Android. Case in point: my wife has a Motorola Backflip that we bought in April. It was released in March. Motorola says it will get Android 2.1 "sometime in Q3". Great. Meanwhile, I pull down the latest version of iPhone OS (now iOS) and install it the same day it's released. You may say that I can't judge Android by one lazy manufacturer. Yup, I sure can. With Apple, my original iPhone has been supported perfectly for 3 years. With Android, I will have to wait for upgrades after Google releases them, possibly indefinitely. Not cool. AT&T We signed a new contract with AT&T in April to get my wife's phone. I've had a reasonable experience with them. I don't imagine my experience with Verizon would be any better, and I'm relatively confident that Sprint doesn't have the coverage it takes to work well for us. The fact is, AT&T, for whatever reason, doesn't have jack for Android phones. May not be Android's fault, but it's still a shortcoming that prevents me from having it just like the iPhone's exclusivity keeps some folks on other networks from having it. Innovation? What Innovation? Android has a nice dashboard and a great notification system and… nothing else original. I keep reading about how disappointing the iPhone is nowadays. "It has no innovation," people say. Who does? Android has modeled its behavior after the iPhone. That's fine, but if all you've got is a similar product and I'm invested both skill-wise and app-wise in my current platform, why should I change? Microsoft's new Windows Phone 7 looks somewhat innovative, and I'm pretty excited to see what they'll bring to the table, but that's another six months away, at least. I've got a 3 year old phone that has some annoying issues now (thanks to recent encounters with water). I need a new phone now. Is This Going to Work? There's no shortage of criticism of Apple over its App Store policies, and I've vented my own anger about it. However, I will give them credit: their screening of apps has done a great job of weeding out the crap and gives an excellent indication that the app will work on my device. How about Android? Nope. It might work on your phone. Maybe. You'll have to try it to see. Get burned by it? Well, write a nasty review to try to keep others from making the mistake you did. If you don't mind doing that stuff, then Android is the platform for you. Personally, I'd rather have a receptionist screening out the telemarketing and survey calls than hang up on them myself, but that's your call. Slow, Slowing, Slower All this yapping about multitasking. This is an area I've been on Apple's side from the beginning. Sorry folks, but this is the number one reason I hated Windows Mobile: the longer you use it, the slower it gets because it doesn't kill apps. I'm with Steve Jobs on this one: if you see a task manager, we're doing it wrong. I don't want to have to manually kill apps. I hate doing that on Windows let alone on a mobile device. To me, priority one should be keeping the device speedy. Waiting for your device to respond is unacceptable. Bonus! Taken from iPhone Letdown? 8 Things Apple Didn't Announce, here are my responses: 4G Yeah, let me know if your area actually has it. I live in Lincoln, Nebraska. No carrier is going to have 4G here for at least 3 years. Meanwhile, you still get to pay for it. Yay! Cloud iTunes/OTA Sync You got me here. Of course, whether or not your Android device will be able to do it is always a good question. 3G Video Chat You got me here, too. I'm sure you spent countless hours in front of your phone with video chat. Also, I can't wait for the "No Video Chat While Driving" laws. Mobile Hotspot This is a neat feature, but as the author points out, it's left up to the carrier whether to implement it or not. Pretty sure any Android phones that come to AT&T won't have this enabled in the foreseeable future. Is Verizon even allowing this? I just figured Sprint was because they're failing so hard at keeping customers. Free MobileMe I use Google's services with my iPhone. The only people I know who use MobileMe are Apple fanboys and fangirls. If you choose to pay for a service that you can get for free, that's your decision, not Apple's. Voice Input Voice input has been available on phones (even "dumb" phones) for years now. iPhone does have the ability, though limited. Why don't I hear people telling their phones what to do? Maybe because it's still easier to use your fingers than talk to it. Get back to me when this becomes an important feature. Free Navigation Maybe this will be a bigger deal to me now that I'm getting a phone with GPS, but when using my buddy's 3gs, Google maps has worked just fine. Maybe I just don't trust turn-by-turn navigation enough to want it. Dashboard The only legitimate complaint on this list, to me. iPhone's home screen is pathetic, doubly so for the iPad. What a waste of perfectly usable space. I also want to add notifications to this list. Android's notification panel is far superior to the iPhone's. I don't want to hunt all over my screen to find little red dots. Put 'em in one place, Apple.

  • Can checkboxes be removed from a .NET WinForms ListView at runtime?

    - by James
    Is it possible to remove the checkboxes from a .NET WinForms ListView control at runtime? The following code appears to have no effect when '.Checkboxes' has initially been set to 'true' and the control has rendered onto a form with checkboxes available for each list view item: // C#: testListView.BeginUpdate(); testListView.Checkboxes = false; testListView.EndUpdate(); Is there a method that must be called to enact this change? What is the use of providing the .Checkboxes property when it defaults to 'false' and only has an effect if set to 'true'?

  • How do I add/remove items to a ListView in virtual mode?

    - by Eric
    If I'm using a ListView in virtual mode then, as I understand it, the list view only keeps track of a small number of items in the list. As the user scrolls it dynamically retrieves items it needs to show from the virtual list. But what if an item is added or removed from the master list? If an item is added/removed outside of the range of indexes being shown by the list view then I would assume the list view would show the added/missing items when the user scrolls to that index. Is this correct? But what if an item is added/removed from the range of indexes the user is currently viewing? How do I trigger the list view to refresh the items it is currently viewing to show the new/missing items?

  • ASP.net Treeview/Listview combination or alternative: Tutorials? Help?

    - by jlrolin
    I need to create an ASP.net page that has a control on the page that has a five-level TreeView on the left side of the page, and accounting balances on the right side the coincide with each breakdown in the tree. Top level is company, next is group, next is program, etc... and the balances break down accordingly. I've seen that there are controls out there such as TreeView/ListView combination controls that can do this. Is there any tutorials or help out there on how to go about accomplishing this without paying for controls? Could a treeview do this alone by spanning data across the entire length of the columns since every level will have totals on it?

  • Winforms - How to allow user to increase font size of listview with hidden controls?

    - by John M
    I am creating an winform application that will run on a tablet PC. One form for this app will have a listview control. I would like to allow the user to change the font size based on preference (ie did they remember their glasses today). A few ways that I can think of would be a numeric-up-down or +/- button controls. Both of these ways require screen real estate that is very limited. Is there a control or technique that would allow font size changes with a hidden-when-not-used control?

  • Trying to implement fling events on an object

    I have a game object, well a bitmap, which I'd like to "fling".

  • "Parse Error : There is a problem parsing the package" while installing Android application

    - by Raghavendra
    I got this error while installing the android application (Parse Error : There is a problem parsing the package.). I did the following steps. First time I installed the application and it works fine. I made changes to the existing application and change the version no in Manifest file. <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="org.openintents.samples.BasicOpenARDemo" android:versionCode="2" android:versionName="1.0.1"> Then I export the application and finish the code signing process. For this, Right Click your Project node select Export. There you will see a wizard. Follow the steps and finish the code signing also. I got the ARDemo.apk file, Then I changed it’s name to ARDemo1.apk Then I shipped this apk file to mobiles SD Card and started the installation I got the above error. I googled, they say that problem with unpacking manifest file. Can anyone tell me what could be wrong with me?
