Can I add more than one period to perform a sync in Android syncAdapter? -

i'm implementing syncadapter , need synchronize few times in day need onperformsync trigger synchronization @ midnight.

contentresolver.setissyncable(account, uribuilder.authority, 1);  bundle extras = new bundle(); extras.putboolean(contentresolver.sync_extras_expedited, false); extras.putboolean(contentresolver.sync_extras_do_not_retry, false); extras.putboolean(contentresolver.sync_extras_manual, false);  contentresolver.addperiodicsync(account,     uribuilder.authority,     extras, 15000);  contentresolver.setsyncautomatically(account, uribuilder.authority, true); contentresolver.requestsync(account, uribuilder.authority, extras); 

yes can. using gcm; once server data changed server send push notification of has been changed. or can use alarmmanager;

    intent intent = new intent(context,             myboradcastreciever.class);      pendingintent sender = pendingintent.getbroadcast(context, uid, intent,             pendingintent.flag_update_current);      alarmmanager = (alarmmanager) context             .getsystemservice(activity.alarm_service);     am.set(alarmmanager.rtc_wakeup, time, sender);

in broadcastreceiver

new broadcastreceiver() {          @override         public void onreceive(context context, intent intent) {             triggerrefresh();           }     }; 

---

 public static void triggerrefresh() {     bundle b = new bundle();     // disable sync backoff , ignore sync preferences. in other     // words...perform sync now!     b.putboolean(contentresolver.sync_extras_manual, true);     b.putboolean(contentresolver.sync_extras_expedited, true);     contentresolver.requestsync(lntaccountservice.getaccount(), // sync                                                                 // account             content_authority, // content authority             b); // extras }
