I have a question regarding creating an android application for travel guide. I am creating it offline. I am familiar with the problem that we access the database on the real device. I want an external database file in which the data is already filled. I just want to include this database in my apk and just want to access that database in my phone offline. I am using SLQite database. I had imported db file from assets folder. It works on emulator but not on a real device due to no access to system files.
