Crash on Android 11 - Githubissues

Google Play library crashes on Android 11 while trying to call TelephonyManager.getNetworkType() without checking READ_PHONE_STATE permission:

The workaround is:

TelephonyManager tm = ...;
if (Build.VERSION.SDK_INT < Build.VERSION_CODES.R) {
    //noinspection MissingPermission
    ... = tm.getNetworkType(); // it's safe to call on pre-Android 11
} else if (ContextCompat.checkSelfPermission(context, Manifest.permission.READ_PHONE_STATE)
        == PackageManager.PERMISSION_GRANTED) {
    //noinspection MissingPermission
    ... = tm.getNetworkType(); // safe to use after the permission was checked
}

Without this fix every game with Google Play Services would crash on Android 11!
