Yes it's null. You have to specify one: http://developer.android.com/reference/android/widget/CursorAdapter.html#setFilterQueryProvider(android.widget.FilterQueryProvider)
The FilterQueryProvider is a mechanism to let you filter the cursor without subclassing CursorAdapter. So either you extend CursorAdapter and override runQueryOnBackgroundThread() *or* you supply a FilterQueryProvider.
