NullPointer at OnDestroy

问题

I'm having an issue that only Crashlytics shown me and my team, I can't reproduce it on my tests devices. It seens that the method onDestroy() is throwing a "NullPointerException".

 @Override
protected void onDestroy() {
    UsersOnRoom.removeAll();
    try {
        audioManager.removeAudioFiles();
    } catch (Exception e) {
        super.onDestroy();
    }
    super.onDestroy();
}

RoomBaseActivity extends another Activity, that has no implementation of onDestroy().

I have no ideia what's is causing it.
