I'm having trouble completing Lesson 4B. After making the changes required for the "Inserts with ContentProvider" quiz, the tests start to fail. >> android.database.sqlite.SQLiteReadOnlyDatabaseException: attempt to write a readonly database (code 1032) << After hours of trying different things, I decided to pull their code from GitHub (the 4.16 branch). I was surprised to see that code failed as well, in exactly the same way. Does this code work for you at all?
