OnPause make sure to clean up the dialog

[benzabill]

If i am running flip progress dialog, and pause the activity that it runs in, and then return back to it, app will crash with the following error (and stack trace doesn't point to anything within app).

java.lang.RuntimeException: Unable to resume activity: java.lang.NullPointerException: Attempt to invoke

 virtual method 'android.view.Window android.app.Dialog.getWindow()' on a null object reference

   at android.app.ActivityThread.performResumeActivity(ActivityThread.java:3429)

My solution:

@Override protected void onPause() {

    super.onPause();

    if(flipProgressButton!= null){

        flipProgressButton.dismiss();

    }

}

I don't know how you want to address this, but perhaps you should have a try{}catch{} in your code, or in readme tell that you need to dismiss
