Android APK sanity check

Hi

I have had the same problem Using old and very new android devices, where
the program will give a blank/black screen on different versions of Android
with no ryme or reason.

Sometimes it works on and older version of android with older hardware and
fails on a phone or tablet with say  the oreo version although the program
only needs a minimum of 4.1. and the api is correct.

The  same android on different hardware might or might not work (black
screen no errors reported no "crash")

YMMV.
