Starting activity intent in AndEngine

I am trying to use the starting another activity intent in AndEngine as I use it in my original Android apps, it doesn't work.

Logcat:

code :

                startActivity(new Intent(StartingActivity.this, MainActivity.class));
                finish();

Note that sometimes it works and sometimes doesn't.

  1. your problem is mEngine is null, in onResumeGame method.
  2. finish(); is not needed.
  3. Do you extend from SimpleBaseGameActivity directly?
  4. Do you use emulator?

@Override
public synchronized void onResumeGame() {
    if (this.mEngine != null)
        super.onResumeGame();
}

solved it by using this code, referrence https://github.com/nicolasgramlich/AndEngine/issues/7
