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...

SurfaceFlinger removed my tabactivity.Will this can cause dialog remove?
Well well problem was with c code some file descriptor fd corrupt was causing this issue.once the issue was solved at c level the problem is not seen.pretty strange though.
