Access a database from Broadcast receiver?

I cant access my SQlite database from my broadcast receiver. Is it even possible? I keep getting a NullPointerException. In the onReceive of the BroadcastReceiver I call

mDbHelper = new ResponderDbAdapter(context);

mDbHelper.open();

Is it something to do with the context? I want to pull database info that gets set in my MainActivity into the BroadCast Receiver.

Ideas?

EDIT: A Better Explanation

I have a separate activity that allows the user to add items to the database. I want to share this with the receiver so that the broadcast receiver knows what items are in the database. ResponderDbAdapter is a class that accesses the Db and performs fetches and inserts to the DB. What would the context be...if I have the broadcast receiver running even if the application is closed how can it access a database?

The Broadcast Receivers version of the context is probably not working for the DBHelper. Have the Receiver fire up a service and have the service access the DB
