android - Why can't I delete using a getContentResolver..? -

-

i can data no problem...but cannot delete data. suggestions..??

                cursor cu = getcontentresolver().query(content_uri, null, null, null, null);             if (cu.movetofirst())             {                 numberindb = cu.getstring(2);                 system.out.println("number in db = " + numberindb);             }              contentresolver c = getcontentresolver();

neither of these next 2 lines work

            c.delete(content_uri, "title ="+ numberindb, null);             getcontentresolver().delete(content_uri, "title ="+ numberindb, null);

if title string, suspect need quote in query:

getcontentresolver().delete(content_uri, "title ='" + numberindb + "'", null)

also, check logcat output , see if there sqlite errors.
