reading values from database of Sqlite

Question

I wanna read database which is already created by my Android application but in some other activity. Like one activity is creating database and other is reading it. But when i started reading thought other activity like this:

List<String> names = this.dh.selectJname();

then this showed "Null pointer Exception".
