I am new to android development. I am creating an app with room persistent library. I already have a pre-populated .db file. I am able to insert and fetch my own data but I am not able to fetch already existing data from the database.

Room doesn't support pre-populated data by default.

but I created this library which helps you to use a pre-populated database from assets folder.

and you can use it like this 

final AppDatabase db = RoomAsset.databaseBuilder(
                getApplicationContext(), AppDatabase.class, "your_db_name.db").build();

see the sample for example.

see this qustion for more alternatives
