NOTE: I am using Room with LiveData. The
LiveData event is fired when database is replaced on some device (I assuming depending on Android version), but not all devices. I guess it would be best practice to restart the activity or app when the database file is replaced.
NOTE: I tested on Mashmallow, Nougat and ICS.
