android - Finalizing a Cursor that has not been deactivated or closed non-fatal error

Question

i'm getting a "Finalizing a Cursor that has not been deactivated or closed" error on this piece of code. The code is used to fill a listview.

Since it's a non-fatal error , there is no crash and all seems to works fine..but i don't like the error.

If i close the cursor at the end of this code..the listview stay's empty. if i close the cursor in onStop , i get the same error.

How do i fix this??

private void updateList() { 
        DBAdapter db = new DBAdapter(this); 
        db.open(); 
            //load all waiting alarm 
            mCursor=db.getTitles("state<2"); 
            setListAdapter(new MyCursorAdapter(this, mCursor)); 
            registerForContextMenu(getListView()); 
            db.close(); 
        } 


error :

Answer 1

You should not be getting that message if you close the Cursor in onStop() or onDestroy(). Please try that again. Or, call startManagingCursor() after you get the Cursor from your query, and Android will close the Cursor on its own.
