 ### Android: Note for switching between v<=v2.0.2 and >=v2.0.3 if you use notification channels with custom sounds
 With versions prior to 2.0.3 of this module, FirebaseCloudMessaging.createNotificationChannel would create the notification sound uri using the resource id of the sound file in the `res/raw` directory. However, as described in this [android issue](https://issuetracker.google.com/issues/131303134), those resource ids can change to reference different files (or no file) between app versions, and  that happens the notification channel may play a different or no sound than originally intended.
