Android SQLite Null Pointer Exception

Question

I am getting this in LogCat:

05-20 17:16:34.721: E/AndroidRuntime(30461): FATAL EXCEPTION: main
05-20 17:16:34.721: E/AndroidRuntime(30461): java.lang.NullPo         


        

Answer 1

Looks like your trying to access the db when it's been closed. Perhaps placing datasource.open() at the beginning of onCreate and datasource.close() at the end of onCreate() and calling them each just once in your class would solve your problem.

If you are editing, creating and deleting items in your activity requiring multiple calls to your database, consider calling datasource.open() at the beginning of a method that accesses the database and then close() at the end of of that method.
