My application is crashing out with the error Caused by: java.lang.NoSuchMethodException: f4.b.<init> [class android.bluetooth.BluetoothAdapter] when I run it in release mode. The app works fine if run in debug mode, or even release mode when installed via Android Studio. The problem is exclusively when running a release build which has been installed via our MDM solution. The stack trace doesn’t appear to me to be particularly helpful:

I have tried setting minifyEnabled false and shrinkResources false but this doesn’t seem to make any difference
