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

I had this error when I missed

@Database(entity="{})

Ensure that the entity model specified in the annotation above refers to the particular model class and also ensure that the necessary annotation:

@Entity(tableName = "" ...)

is properly defined and you'd be good
