  android multithreading android-ndk jni
  My application makes multiple calls from native threads to java, i am seeing the memory usage of the application slowly creeping up. It looks like the calls to attach and detach cause JAVA to leak a thread. I can see this by running DDMS memory analyser.I have written a really simple test app that demonstrates my issue, start test is called from JAVA and kicks off the thread. It doesn’t do anything other then attach and then detach the worker thread.void detachFromThread(JavaVM *vm) {if(vm != NU

  android animation video text opengl-es
  We are trying to create a text animation like Transition and Zoom on the Video. We are not able to get Smooth transition and the effect is so jerky. Then we understood sub pixel rendering is not possible in android. What alternatives can we think of? Can we solve this problem in OpenGL?Ok… I would like to add more to my question….We are actually trying to implement text animations on top of a video which is played by a native player on a surface view. We tried to achieve the text animation

  android toast android-xml
  I know that I could do all of this easily with a custom toast layout, but in creating a custom layout, I would no longer be using the system’s default toast view.Example: Toasts of course look different in Android 2.2 vs Android 4.0. If I create a custom view for my toast, then it will look the exact same in both versions, but what I want is for it to retain its… “Androidiness” for lack of a better word. Basically, does anyone know of a default toast XML layout? Is that even possible?

  android resources android-widget appwidget
  I need to determine the screen density at runtime in an Android AppWidget. I’ve set up an HDPI emulator device (avd). If set up a regular executable project, and insert this code into the onCreate method:DisplayMetrics dm = getResources().getDisplayMetrics(); Log.d(“MyTag”, “screen density ” + dm.densityDpi);This outputs “screen density 240” as expected.However, if I set up an AppWidget project, and insert this code into the onUpdate method:DisplayMetrics dm = context.getResources().getDisplay

  android appwidget viewstub
  I wonder whether it’s possible to inflate a ViewStub using a layout with unsupported views inside an Android appwidget (for example, an ScrollView or WebView).I know that only views with the @RemoteView annotation in its declaration are available to the RemoteViews mechanism, but this restriction remains when inflating layouts at runtime?

  android android-widget screen-orientation appwidget
  I have code in an appwidget that I want to run when the phone’s orientation changes on the home screen, ie like when the keyboard flips out. I have an image that I want to change in an imageview in my appwidget. I can’t use different layouts linked to the orientation (ie “layout” and “layout-land”) because I don’t know the name of the image file until runtime, it is created at runtime. Is there anyway to trigger code to run only if the home screen is shown, my appwidget is active and the orienta

  java android resize appwidget
  I know that one cannot change the size of an app widget. But what to do if I need to? I know that there can be several receivers in AndroidManifest.xml, each with its own provider_info.xml, but users can switch between them only while adding widget on the homescreen. Is there any way to switch between different app widget providers at runtime?

  android appwidget
  Dear all, I am trying to set the position of a TextView within an appwidget. Basically, the direct access to properties af the TextView works:myRemoteView.setTextColor(R.id.myTextView, Color.WHITE); //worksAlso indirectly, I can access the TextView properties:myRemoteView.setInt(R.id.myTextView, “setTextColor”, Color.BLUE); // worksAnd setting float values also works:myRemoteView.setFloat(R.id.myTextView, “setTextSize”, 25); // worksNow I’m trying to shift the x position of the TextView by 5 p

  android service appwidget
  I have an android Activity extending AppWidgetProvider in which I’d like to keep a count of how many times onReceive() is called. The problem is, every once in a while there is an entry in Logcat saying “No longer want blah.foo.bar.baz” and shortly afterwards an entry saying “Scheduling restart of crashed service blah.foo.bar.baz”. Android kills and then restarts my process which causes all my variables to initialize to default values. Only way I can think of to maintain variable state is to wr

  android appwidget backlight screen-brightness
  I have created a simple Appwidget to control the brightness of the screen by this code:android.provider.Settings.System.putInt(context.getContentResolver(), android.provider.Settings.System.SCREEN_BRIGHTNESS, 50);When i click the widget, there is no change in the brightness of the backlight immediately. But when i lock and unlock the phone, it works. I read Changing screen brightness programmatically (as with the power widget) that using dummy activity will give the solution. So i created an act

  java android appwidget
  What am I doing?I am updating an AppWidget using an IntentService. What is the problem?Everything works perfectly well except for some rare times probably every 12-15 hours or I might say random, the widget updates don’t happen. After debugging through the situation here is the logcat message which appears to be the problem.05-27 20:21:13.122: WARN/ActivityManager(97): Scheduling restart of crashed service com.myapp.android/.myAppWidget$UpdateService in 5000msBelow are some more logcat messages
