Apparently , I have found my solution. I misses a super.onStop() in an Activity, that was careless of me. Apologize and thanks for all of your times!
It might be the way you try call intent for Login Activity from your mainActivity or where ever you try create the intent I usually use
Intent i = new Intent(this, Page2.class); // Change to LoginActivity.class
i.putExtra("isNewUser","true"); // Optional
startActivity(i);
You might be doing this already, I'm not sure as your code to call this class isn't included.
Also you should add a default case to your switch statement it could prevent tricky bugs further down the road.
