public class customalarm extends activity {           alarmmanager am;           long timeinmilliseconds;          @override          public void oncreate(bundle savedinstancestate) {           super.oncreate(savedinstancestate);           setcontentview(r.layout.custom_alarm);           = (alarmmanager) getsystemservice(context.alarm_service);           setonetimealarm();           string date = new simpledateformat("yyyy-mm-dd").format(new date());           string givendatestring = date+" "+"09:34:00 gmt+05:30 2013";            simpledateformat sdf = new simpledateformat("yyyy-mm-dd hh:mm:ss z yyyy");           try {               date mdate = sdf.parse(givendatestring);                timeinmilliseconds = mdate.gettime();               system.out.println("date in milli :: " + timeinmilliseconds);           } catch (parseexception e) {                       e.printstacktrace();           }          }           public void setonetimealarm() {           intent intent = new intent(this, timealarm.class);           pendingintent pendingintent = pendingintent.getbroadcast(this, 0,             intent, pendingintent.flag_one_shot);           am.set(alarmmanager.rtc_wakeup,                   timeinmilliseconds, pendingintent);          }           public void setrepeatingalarm() {           intent intent = new intent(this, timealarm.class);           pendingintent pendingintent = pendingintent.getbroadcast(this, 0,             intent, pendingintent.flag_cancel_current);           am.setrepeating(alarmmanager.rtc_wakeup, system.currenttimemillis(),             (5 * 1000), pendingintent);          }          }
