NullPointerException

[sake]

Hello there. Sometimes it occurs that in BaseGameActivity this part here:

Code: Select all

@Override
   public void onResumeGame() {
      Debug.d(this.getClass().getSimpleName() + ".onResumeGame" + " @(Thread: '" + Thread.currentThread().getName() + "')");

      this.mEngine.start();

      this.mGamePaused = false;
   }


is being executed without mEngine being initialized (at game startup). Can that be because of the debugging process (Old Thread not being killed completely and for that reason onResumeGame being called?)

I think it's because the life cycle of the program (I copy following text from another post)?

I guess onResume occurs before onCreateGame, so mEngine hasn't been initialized yet. Maybe you should add conditional structure here:

1.       if (this.mEngine != null)
2.             this.mEngine.start();
3.  
4.       this.mGamePaused = false;

This is a bug in the whole repository. This is in the AndEngine class. So this should be fixed as fast as possible!
