Android room persistent: AppDatabase_Impl does not exist

Question

My app database class

@Database(entities = {Detail.class}, version = Constant.DATABASE_VERSION)
public abstract class AppDatabase extends RoomDatabase {

            


        

Answer 1

In my case, I was testing the connectivity for room database and I have put the testing class inside the directory which I have created inside the AndroidTest folder. I have moved it out of the custom directory, then it worked pretty well.
