Room database throwing error after reinstalling - Room cannot verify the data integrity

Question

I am in the project development phase. So, I basically do not need migrations at this point in time. I had FirstTable before and SecondTable is the newly added one. I already had prepackaged db also. Below is the code used.

@Database(
    entities = [
        FirstTable::class,
        SecondTable::class
    ],
    version = 1,
    exportSchema = true
)
abstract class MyDatabase : RoomDatabase() {

    companion object {
        private const val databaseName = "my-db"
        private const val prepackagedDB = "prepackaged-db"

        fun buildDatabase(context: Context): MyDatabase {
            return Room.databaseBuilder(context, MyDatabase::class.java, databaseName) 
                .createFromAsset(prepackagedDB) 
                .build()
        }
    }
}

I have also given android:allowBackup="false" in AndroidManifest.xml. I do not want to use fallbackToDestructiveMigration() which clears my prepackaged db too.

I uninstalled the app in the emulator(API Level 29) and ran the app. I am getting this error.

I am not able to understand why reinstalling is causing this issue. Could someone let me know what I went wrong?

Answer 1

Included the new table(an empty one) in the prepackaged DB and then it's working fine.
