Android Back Key Issue

Question

I'm developing a game via Andengine for Android. I have big problem. When I open my game first time, it's opening well. And when I press back key button(which is on device, pyhsical button), the app is closing. But it mustn't be close. And here is the LogCat:

And when I try to open app again, it is opening black blank scene.

PLS help!

Answer 1

try to override onKeyDown and block BACK button

@Override
public boolean onKeyDown(int keyCode, KeyEvent event) 
{
    if(keyCode==KeyEvent.KEYCODE_BACK)
        return true;

    return super.onKeyDown(keyCode, event);
}

That should prevent user from exit App with Back button
