About the Pollingservice timed polling task in Android

1. Create a Pollingthread class and print "New message!" in log

class extends Thread {        @Override        publicvoid  run () {            log.i ("Zzf", "Polling ...") );        }    }

2. Create Pollingreceiver to receive service delivery information and re-execute Pollingservice

 Public class extends broadcastreceiver {    @Override    publicvoid  onreceive (context context, Intent Intent) {        //  TODO auto-generated method stub        log.i ("Zzf", "receive!" );         New Intent (context, Pollingservice.  Class);        Context.startservice (i);    }}

3. Create a Pollingservice timed poll task object

 Public classPollingserviceextendsService {@Override Publicibinder onbind (Intent Intent) {return NULL; } @Override Public voidonCreate () {} @Override Public intOnstartcommand (Intent Intent,intFlagsintStartid) {        //TODO auto-generated Method Stub//Create a Pollingthread child thread for performing tasks        NewPollingthread (). Start (); //Get Alarmmanager System ServicesAlarmmanager Manager =(Alarmmanager) Getsystemservice (Context.alarm_service); //packaging needs to perform service intentIntent i =NewIntent ( This, Pollingreceiver.class); Pendingintent pendingintent= Pendingintent.getbroadcast ( This, 0, I, 0); intAnseconds = 5 * 1000;//5 Seconds//Trigger Time        LongTriggerattime = Systemclock.elapsedrealtime () +Anseconds;        Manager.set (Alarmmanager.elapsed_realtime_wakeup, Triggerattime, pendingintent); return Super. Onstartcommand (I, Flags, startid); }
