FATAL EXCEPTION: main on BT connection

Every time I start the car engine and car audio powers up I got "FATAL EXCEPTION: main".

```
E AndroidRuntime: FATAL EXCEPTION: main

I've already reported this multiple times using the app builtin method.
It's good that Google doesn't know about this since I'm using microg instead of gapps (:
