Android APK sanity check

Thanks for the comments. I've actually seen the problem with initial 
startup on a few apps but in this case a relaunch still crashes. :(

Since you have a few older devices, it might help the team narrow down 
what's affected if you try out my test stack. Bug report is here:

I only have Android Marshmallow on my test phone(s) but I'm betting it 
will fail with any older OS. Or it may be the version of Java I 
installed, which I believe LC 9 required.
