Android: Activity Dialog / Dialog disappears unexpectedly

Question

I have an application with TabActivity in which I am displaying a dialog each time I get a callback from my engine (NDK C code). I make sure dialog is displayed when app is in resume state.

Upon receiving the callback from the engine, I start the NetworkDownDialog activity, but this causes the dialog to stay for a second and then disappear. The same thing happens if I use Dialog or AlertDialog. Most strangely, the disappearance seems random (doesn't always happen).

This is an S3 device. What's going on?

Network Down Dialog Code

public class NetworkDownDialog extends Activity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.network_down);
        Logger.d("NetworkDownDialog", "----------onCreate-----------");
        registerReceiver(mNetworkDownReceiver, new IntentFilter("NetworkDown"));
    }
    @Override
    protected void onDestroy() {
        super.onDestroy();
        unregisterReceiver(mNetworkDownReceiver);
        Logger.d("NetworkDownDialog", "------onDestroy-------");
    }
    @Override
    protected void onResume() {
        super.onResume();
        Logger.d("NetworkDownDialog", "------onResume-------");
    }
    @Override
    protected void onRestart() {
        super.onRestart();
        Logger.d("NetworkDownDialog", "------onRestart-------");
    }
    @Override
    protected void onStart() {
        super.onStart();
        Logger.d("NetworkDownDialog", "------onStart-------");
    }
    @Override
    protected void onStop() {
        super.onStop();
        Logger.d("NetworkDownDialog", "------onStop-------");
    }
    @Override
    public void onBackPressed() {
        Logger.d("NetworkDownDialog", "------onBackPressed Do nothing-------");
    }
    private BroadcastReceiver mNetworkDownReceiver = new BroadcastReceiver() {
        @Override
        public void onReceive(Context context, Intent intent) {
            finish();
        }
    };
}

In the logs, this is what I see:

In this case, the ActivityDialog disappeared after the above.

Why is my dialog disappearing? Is it possible that memory corruption at my C level native code is causing this problem? Am I doing something wrong on the UI side? I'm totally stuck...

05-24 19:49:00.025 I/SurfaceFlinger( 1901): id=2147 Removed NainTabActivity idx=-2 MapSz=4

SurfaceFlinger removed my tabactivity.Will this can cause dialog remove?

Answer 1

1. Make Sure that the you are displaying the dialog with application context.
2. Make sure no two events come and hit the same part of code.i.e when you are about to display the dialog,one more event from c code to display the dialog.
3. Make Sure your application has enough memory to run smoothly.

Answer 2

After seeing your code, I would recommend that you remove finish() in your BroadcastReceiver and run your program (for testing purposes). The problem you're seeing may happen due to having your Activity starting and ending almost at the same time.

Answer 3

I think the problem is due to the surface not being locked. Here are some solution which I found at SO.

Hope they help.
