• Redirect Log output to sdcard on customer's phone

  - by Tom

  My customers are having a problem with my app, and I have been unable to reproduce the problem on my development phone. How to debug this problem? The android Log class is great, but my customers do not know how to use 'adb' or the USB debug cable. Is there some way to redirect Log output to a file on the phone's SD card? Then the customer could easily email the log file to me. Even if this redirection requires programming on my part, I could at least distribute a 'debug' version of the app. Thanks, Tom

• Save HashMap data into SQLite

  - by Matthew

  I'm Trying to save data from Json into SQLite. For now I keep the data from Json into HashMap. I already search it, and there's said use the ContentValues. But I still don't get it how to use it. I try looking at this question save data to SQLite from json object using Hashmap in Android, but it doesn't help a lot. Is there any option that I can use to save the data from HashMap into SQLite? Here's My code. MainHellobali.java // Hashmap for ListView ArrayList<HashMap<String, String>> all_itemList; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main_helloballi); all_itemList = new ArrayList<HashMap<String, String>>(); // Calling async task to get json new getAllItem().execute(); } private class getAllItem extends AsyncTask<Void, Void, Void> { @Override protected Void doInBackground(Void... arg0) { // Creating service handler class instance ServiceHandler sh = new ServiceHandler(); // Making a request to url and getting response String jsonStr = sh.makeServiceCall(url, ServiceHandler.GET); Log.d("Response: ", "> " + jsonStr); if (jsonStr != null) { try { all_item = new JSONArray(jsonStr); // looping through All Contacts for (int i = 0; i < all_item.length(); i++) { JSONObject c = all_item.getJSONObject(i); String item_id = c.getString(TAG_ITEM_ID); String category_name = c.getString(TAG_CATEGORY_NAME); String item_name = c.getString(TAG_ITEM_NAME); // tmp hashmap for single contact HashMap<String, String> allItem = new HashMap<String, String>(); // adding each child node to HashMap key => value allItem.put(TAG_ITEM_ID, item_id); allItem.put(TAG_CATEGORY_NAME, category_name); allItem.put(TAG_ITEM_NAME, item_name); // adding contact to contact list all_itemList.add(allItem); } } catch (JSONException e) { e.printStackTrace(); } } else { Log.e("ServiceHandler", "Couldn't get any data from the url"); } return null; } } I have DatabasehHandler.java and AllItem.java too. I can put it in here if its necessary. Thanks before ** Add Edited Code ** // looping through All Contacts for (int i = 0; i < all_item.length(); i++) { JSONObject c = all_item.getJSONObject(i); String item_id = c.getString(TAG_ITEM_ID); String category_name = c.getString(TAG_CATEGORY_NAME); String item_name = c.getString(TAG_ITEM_NAME); DatabaseHandler databaseHandler = new DatabaseHandler(this); //error here "The Constructor DatabaseHandler(MainHellobali.getAllItem) is undefined }

• Limit size of cache directory.

  - by M.A. Cape

  I have some questions about the cache directory in android. Does anyone knows the limit for each app's cache directory? Also what will happen if there is not enough disk space to cache data? All I know is when the device runs low on storage, the files here (cache directory)will be the ones that get deleted first and each app has its own cache directory. Now, are the files of other app's cache directory will be cleared to accommodate my app's request to add files in the cache dir when there is not enough storage?

• How can I update the version of an APK which I did not create myself

  - by sylvanaar

  I am new to Android development. I am using a x-platform development tool which builds and signs the APK for me. This tool has a bug and it does not generate APK's with the version number I specify, all APK's generated are version 1.0. I would like to unpack the APK, edit the version number, and then resign and repackage it. It was signed using my keystore originally, so I have the keys needed to sign it again. How can this be done?

• Trouble getting height of OverlayItem Drawable

  - by Bloudermilk

  Hey- I'm having some trouble getting a hold of the drawable a certain OverlayItem is using so I can calculate the height of it and properly offset the note that shows onTap. Here is my code to try to get that drawable: Drawable marker = item.getMarker(android.R.attr.state_focused); if (marker != null) int markerHeight = marker.getIntrinsicHeight(); marker ends up null. I'm using a drawable XML file with a selector for the different states of the OverlayItem's drawable. In it I'm specifying a drawable for the null state, state_focused, and state_pressed. Thanks for any help! -Nick

• IntentNotFoundException for TextToSpeech.Engine.ACTION_INSTALL_TTS_DATA

  - by Casebash

  I am trying to implement text to speech by following this article on the Android Developers Blog. It suggests the following code for installing text to speech data if it is not supported. Intent installIntent = new Intent(); installIntent.setAction(TextToSpeech.Engine.ACTION_INSTALL_TTS_DATA); startActivity(installIntent); This throws an Exception: ActivityNotFoundException: No activity found to handle Intent However, I am using the code here to determine the the intent is actually supported. Here is the list representation: [ResolveInfo{43cc5280 com.svox.pico.DownloadVoiceData p=0 o=0 m=0x108000}] Why doesn't this work?

• Implement subitem in SQLite

  - by Mohit Deshpande

  How could I implement a sub item where the item would have a parent to that of the same item. For example, I have a database that holds tasks/todos. Each todo has a title(TEXT), completed(INTEGER [1 if true, 0 if false]), and due date(TEXT) column. I would like to add functionality to have subtasks, where a task could possibly have a parent task. How would I implement this in SQLite for Android? NOT IN SQL! So no foreign keys (triggers are allow, though)! Could I just have a separate table (subtask) and have a foreign key trigger to link subtask(INTEGER parent) to task(INTEGER PRIMARY KEY AUTOINCREMENT _id)? Or should I add a column to my original task table(INTEGER parent)? How could I implement this?

• Making Eclipse behave like Visual Studio

  - by FlySwat

  I'm doing some Android dev, and I much prefer Visual Studio, but I'll have to use Eclipse for this. Has anyone made a tool that switches Eclipse to look and behave more like visual studio? I mainly can't stand its clippyesqe suggestions on how I should program (Yes, I know I have not yet used that private field! Thanks Eclipse!), or its incredibly lousy intellisense. For example, in eclipse, if I don't type "this" first, its intellisense won't realize I want to look for locally scoped members. Also, the TAB to complete VS convention is drilled into my head, and Eclipse is ENTER to complete, I could switch everything by hand but that would take hours, and I was hoping someone had some sort of theme or something that has already done it :)

• Show extra info for Preference screens when CheckboxPreference summary field is not enough long?

  - by Pentium10

  I have situation when you can enabled/disable modules for my Android application. For this I use a CheckboxPreference screen. This is all good, but the summary field gets cut off if longer descriptions are added than 2 lines. Suppose I have 4-5 lines of description available for each module, I would like to display this in a helper window. I tried to bind a click event to the CheckboxPreference, but that fires for the whole line, so not only when the checkbox is clicked, and more, where ever you click on the line the checkbox is toggled. So now I am wondering if this can be fixed. So if the user needs more info, just taps the text and the helper opens up, and if want to toggle the settings it taps the checkbox. How would you do it? I am open to other ideas too, if they do work.

• Notifying when screen is off

  - by Al

  I'm trying to generate a notification which vibrates the phone and plays a sound when the screen is off (cpu turned off). According to the Log messages, the notification is being sent, but the phone doesn't vibrate or play the sound until I turn the screen on again. I tried holding a 2 second temporary wakelock (PowerManager.PARTIAL_WAKE_LOCK), which I thought would be ample time for the notification to be played, but alas, it still doesn't. Any pointers to get the notification to run reliably? I'm testing this on an G1 running Android 1.6. Code I'm using: notif.vibrate = new long[] {100, 1000}; notif.defaults |= Notification.DEFAULT_SOUND; notif.ledARGB = Color.RED; notif.ledOnMS = 1; notif.ledOffMS = 0; notif.flags = Notification.FLAG_SHOW_LIGHTS; notif.flags |= NOTIF_FLAGS; //static var if (!screenOn) { //var which updates when screen turns off/on mWakeLock.acquire(2000); } manager.notify(NOTIF_ID, notif);

• Mobile Application Upgrade/Update Framework

  - by sharjeel

  I am developing a few mobile apps for different platforms including Blackberry, Windows Mobile, Android and Symbian S60. I want my mobile apps to have the capability of checking for updates before starting and in case a new version is available, prompt the user to upgrade. Moreover in certain cases (like security patches), the user must be forced to update or the app won't work. Surely I can cook some code to achieve the task but I was wondering if there are already existing framework to serve the purpose so that I don't have to re-invent the wheel and test all over?

• Typical text encoding and EOL behavior on mobile devices

  - by Dan W

  Typical things to worry about when dealing with text are the BOM/signature, encoding, and the end of line (EOL) char/chars. I know that Windows often favours \r\n (CR+LF) and Mac/Linux favours \n (LF), but how about popular mobile devices such as the iPhone and Android? Do typical apps on those platforms favour one or the other (or maybe even \r for iOS)? I'll supply both types to the user just in case, but I'd like to choose one as default. Also, which text encodings are mobiles most likely to use - UTF-8, iso-8859-1, Windows 1252 (or other default codepage) or maybe even UTF-16? And if they use UTF-8/16, are they likely to need (or require not having) a BOM/signature? What is the typical behavior here? Once again, I'll supply a range of encodings to the user just in case, but I'd like to prioritize or use certain encodings as default if it's appropriate.

• Keeping the application state - deploy/install apk

  - by Buffalo

  I'm trying to have my application minimized when paused and then when it's resumed, it should be restored to its previous state, not recreated. This works perfectly when deploying the application on a device/emulator from Eclipse. The problem occurs when I get the apk (either from bin\ or from Project - Android tools - Export signed application package) and install it on a device with a file browser (Astro): the application is destroyed when paused and then recreated. I can call moveTaskToBack(true); in my activity, yet it will still be recreated when launching it. All the discussions around this are based on achieving the opposite: closing the application when minimizing it. Is there any way of achieving what I want?

• Drawing random circles

  - by ViktorC

  I am trying to draw a cupola circles at random positions in an Android application. I draw them on a bitmap and then draw that bitmap on the canvas. This is the function where a draw the circles: private void drawRandomCircles(int numOfCircles) { Canvas c = new Canvas(b); Paint cPaint = new Paint; cPaitn.setColor(Color.RED); for(int i = 0; i < numOfCircles; i++) { int x = Math.Random % 100; int y = Math.Random % 100; c.drawCircle(x, y, 20, cPaint) } } The Bitmap b is global. And after calling this function I just draw the bitmap in the onDraw method. Now the problem is that I only get one circle drawn on the screen, no matter the size of numOfCircles. Any clue what is happening here?

• Is there a way to animate on a Home Widget?

  - by David

  Hi All, I want to use an animation on a Home page Widget, i.e. an AppWidgetProvider. I was hoping to use the "Frame Animation" technique: http://developer.android.com/guide/topics/graphics/2d-graphics.html#frame-animation which I've used successfully in an activity. But I can't translate that code to an AppWidgetProvider. Basically, in an AppWidgetProvider, I create and work with a RemoteViews object, which AFAIK doesn't provide me with a method to get a reference to an ImageView in the layout for me to call start() on the animation. There is also not a handler or a callback for when the widget displays so I can make the start() call. Is there another way this can be done? I suppose that I can probably do the animation on my own with very fast onUpdate() calls on the widget, but that seems awfully expensive.

• How to make a secure login using UDID or device token?

  - by Erik B

  So I'm making an app where I want the users to be able add, edit and rate content, but I do not want to force them to register. Instead I was planning on just using their device id or device token to identify them. I'm planning on making both an iPhone and Android version, so I'm looking for a general solution, but the iPhone version has higher priority, so an iPhone specific solution would also be welcome. The problem is that I don't want just anyone to be able to use my web service by sending a phony device id or someone else's device id. How would the client prove to the server that it is providing the correct device id?

• How to refresh an activity?

  - by poeschlorn

  Hi Guys, after implementing some Android Apps, including several Map activities, I try to refresh the activity when the GPS listener's onLocationChanged() mehtod is called. I have no Idea how to tell the map activity to refresh on its own and display the new coords... the coords to store will have to be in global values, so that the location listener will have access to it. In my sample GPS-class (see code below) I just changed the text of a text view....but how to do that in map view? private class MyLocationListener implements LocationListener { @Override public void onLocationChanged(Location loc) { final TextView tv = (TextView) findViewById(R.id.myTextView); if (loc != null) { tv.setText("Location changed : Lat: " + loc.getLatitude() + " Lng: " + loc.getLongitude()); } } I think the solution of this Problem won't be very difficult, but I just need the beginning ;-) This whole app shall work like a really simple navigation system. It would be great if someone could help me a little bit further :) nice greetings, Poeschlorn

• How to correctly size containing views

  - by Gerry

  I have an Activity that will display a custom view made up of 2 parts. I want one part to be 1/3 of visible screen height, the other part to be 2/3. I can override onMeasure and use display metrics to find the height of the display, but this does not account for the battery bar or view title sizes. DisplayMetrics dm = new DisplayMetrics(); ((WindowManager)contxt.getSystemService(Context.WINDOW_SERVICE)).getDefaultDisplay().getMetrics(dm); int height = dm.heightPixels; How can I tell the height of the displayable area? I'm prepared to override the layout or whatever. What is the Android best practices? I've seen other questions along this line, but they are inconclusive.

• Using an empty keystore password used to be possible?

  - by TomTasche

  When signing an apk after a long break from Android development I was surprised that I'm no longer able to enter an empty keystore password to unlock it. Is it just me or has this been possible before? If so, when did that change and how can I manage to unlock the keystore anyway? Some background: maybe I'm just crazy and didn't use an empty password for the keystore before, but the one and only possible password that I could have been using instead doesn't work either (I swear, there's no chance I'd have used another password!).

• Pass in the object a java class is embedded in as a parameter.

  - by Leif Andersen

  I'm building an android application, which has a list view, and in the list view, a click listener, containing an onItemClick method. So I have something like this: public class myList extends ListActivity { @Override public void onCreate(Bundle savedInstanceState) { getListView().setOnItemClickListener(new OnItemClickListener() { public void onItemClick(AdapterView<?> parent, View view, int position, long id) { /* Do something*/ } } } Normally, this works fine. However, many times I find myself needing too preform an application using the outer class as a context. thusfar, I've used: parent.getContext(); to do this, but I would like to know, is that a bad idea? I can't really call: super because it's not really a subclass, just an embedded one. So is there any better way, or is that considered cosure? Also, if it is the right way, what should I do if the embedded method doesn't have a parameter to get the outside class? Thank you.
