[android-developers] Re: How to add a ViewFlipper to the layout?
How can I make use of adb logcat, DDMS, or the DDMS perspective in Eclipse if I can't reproduce the error in the emulator? It doesn't crash there. Have I implemented the right aproach with the threads? I call on yield() on the 2d thread for every onResume() and onPause() call to the 2d activity. I call on yield() on the 3d thread for every onResume() and onPause() call to the 3d activity. I have set the priorities to MIN_PRIORITY. Is it better to implement the threading in some other way? I also call on finish() on the current activity after every call to startActivity. The app seems to run slower after starting the 3d activity several times. This did not happen when I used the view flipper. Is it possible that several instances of the 3d activity are on the activity stack? This is how I start the activities: Intent glIntent=new Intent(astral.worlds2.GLActivity); glIntent.setFlags(Intent.FLAG_ACTIVITY_REORDER_TO_FRONT); getContext().startActivity(glIntent); On Sep 22, 9:11 pm, Mark Murphy mmur...@commonsware.com wrote: Use adb logcat, DDMS, or the DDMS perspective in Eclipse to examine LogCat and figure out what the crashes are.

Thanks, it got stable when I removed the finish() calls and added this
code to the 2d view class:
@Override
public void onWindowFocusChanged(boolean hasWindowFocus) {
if (!hasWindowFocus) {
thread.setRunning(false);
thread.yield();
} else {
thread.setRunning(true);
thread.yield();
}
