Can't downgrade read-only database from version 2 to 1
Hello! Trying to create pre-populated database.
My Database
@Database(entities = {Series.class}, version = 2, exportSchema = false)
...
public static AppDatabase getDatabase(Context context) {
if (INSTANCE == null) {
synchronized (AppDatabase.class) {
if (INSTANCE == null) {
INSTANCE = RoomAsset.databaseBuilder(context,
AppDatabase.class, DB_NAME)
.allowMainThreadQueries()
.build();
}
}
}
return INSTANCE;
}
Problem is: `I/SQLiteAssetHelper: successfully opened database cymbalsbase.db
W/SQLiteAssetHelper: Can't downgrade read-only database from version 2 to 1:
Upgrading database cymbalsbase.db from version 2 to 1...
missing database upgrade script: databases/cymbalsbase.db_upgrade_0-1.sql
E/SQLiteAssetHelper: no upgrade script path from 2 to 1
D/AndroidRuntime: Shutting down VM
E/AndroidRuntime: FATAL EXCEPTION: main`
What can i do?
try to uninstall the current version and install a new one and see if the problem still exists.
I can't reproduce this error on my end, can you provide the steps leading to this exception?
I uninstall app on emulator and install it, then i get this error.
Can you tell me how i can provide steps?
I still can't reproduce your error. can you provide a minimum working example so I can work on fixing this problem.
W/SQLiteAssetHelper: Can't downgrade read-only database from version 2 to 1 I solve this problem by using read-write database instead or you can change database version to 1.
