public static boolean deletecontact(context ctx, string phone) {          uri contacturi = uri.withappendedpath(contactscontract.phonelookup.content_filter_uri, uri.encode(phone));         cursor cur = ctx.getcontentresolver().query(contacturi, null, null, null, null);         try {             if (cur.movetofirst()) {                 {                     string lookupkey = cur.getstring(cur.getcolumnindex(contactscontract.contacts.lookup_key));                     uri uri = uri.withappendedpath(contactscontract.contacts.content_lookup_uri, lookupkey);                     ctx.getcontentresolver().delete(uri, null, null);                 } while (cur.movetonext());             }          } catch (exception e) {             system.out.println(e.getstacktrace());         }         return true;     }

try use code.

    contentresolver cr = getcontentresolver();     cursor cur = cr.query(contactscontract.contacts.content_uri,     null, null, null, null);     while (cur.movetonext()) {     try{         string lookupkey = cur.getstring(cur.getcolumnindex(             contactscontract.contacts.lookup_key));         uri uri = uri.withappendedpath(contactscontract.             contacts.content_lookup_uri, lookupkey);         system.out.println("the uri " + uri.tostring());         cr.delete(uri, null, null);     }     catch(exception e)     {       system.out.println(e.getstacktrace());     }     }

to delete specific contact modify query according needs.

cr.delete(uri, null, null);
