Crash on Android 6.0.1 Galaxy J3 Luna Pro

I: have a small (8 screen) app that runs out of the play store / app store fine on a variety of emulators and real phones and tablets. I have one phone that it crashes on startup just in the play store… It is a Galaxy J3 Luna Pro running Android 6.0.1.

Here is the Logcat *:F: Can anyone tell me why this is failing?
