So I did get the crashes to stop, and I have a idea of why it works... anyways.. I updated the onWindowFocusChange set the backGroundDrawable to null when the app loses focus. I also do this on the onDestroy() and onPause() methods as well.
My guess is that the app goes into pause mode and when restarted since I was reattaching the same animation to the ImageView it was causing a leak. Note this ImageView and Animation were not static variables they were loaded only on the onWindowFocusChange event. I made the assumption since I was not letting my ImageView and Animation be created as static variables I wouldn't leak the Context, but apparently the recreation of the animation attachment to the ImageView was for some reason, this I'm not 100% sure on, but it seems to be the case.
