setNotificationUri

Cursor c = qb.query(mTasksDb,
projection,
selection, selectionArgs,
null, null,
orderBy);

c.setNotificationUri(getContext().getContentResolver(), uri);

return c;
}

In above query implementation for content provider,
can I delete the line c.setNotificationUri(getContext().getContentResolver(),
uri) ??

You can certainly do that if you want to, but if you do, then you won't be
notified if someone goes and modifies the data.
