    Default A problem with return.

    String rows[] = new String[] {KEY_GAL_ID};   
    Cursor c = ourDatabase.query(GALLERY_TABLE, rows,KEY_ROWID + "=" + rowId,null, null, null, null);
    String result = "";
     
    if(c.moveToFirst())
    {
    	result = c.getString(0);
    	return result;
    }
    else{
    	return "null";
    }
    Why always null is returned even when c.moveToFirst() is true and the program start to execute this row:result = c.getString(0);

    Why always null is returned
    Is the value: null returned
    or is the String: "null" returned?

    There is a difference.
    If you don't understand my answer, don't ignore it, ask a question.

    Then either:
    the method: c.moveToFirst() is returning false
    or c.getString(0) is returning: "null"
    If you don't understand my answer, don't ignore it, ask a question.
