When running the code from the room branch for the first time, it compiled and ran fine. However when I tried to save an item, it would crash. The logcat said the DB schema had changed and the version number needed to be updated. I went into ItemRoomDatabase.kt and updated version = 2 and the code worked as expected. FYI.
