Service timertask stop automatically android -

i have service running in background various timertask periodically interval of 10 mins.

the service works fine until application in foreground , moment app killed timertask behaves strangely example not getting called in every 10 mins.

i saw common issue , been through many answers nothing seems working me. here code snippets.please guide me wrong...

public class myservice extends service { @override public void oncreate() {     super.oncreate();     myservicerunningbackground();     service = myservice.this;     log.d(tag, "myservicemain");     myservicerunningbackground();     message msgobj = servicehandler.obtainmessage();     servicehandler.sendmessage(msgobj);     running = true; }  public final  handler servicehandler = new handler() {     public void handlemessage(message msg)     {         if(null != servicetimer)         {             servicetimer.cancel();             servicetimer.purge();             servicetimer = null;         }         servicetimer = new timer();          servicetimer.scheduleatfixedrate(new myservicemonitorpower(service, target), delay_timer_time, timer_start_time);         servicetimer.scheduleatfixedrate(new myservicemonitorlocation(service, target), delay_timer_time, timer_start_time);         /* if(target.equals(target.server))         {*/         servicetimer.scheduleatfixedrate(new myservicemonitortrafficstats(service, target), delay_timer_time, timer_start_time);         // }      } }; @override public int onstartcommand(intent intent, int flags, int startid) {     if(intent != null)     {               settimerinfo(intent.getstringextra("current"));         message msgobj = servicehandler.obtainmessage();         servicehandler.sendmessage(msgobj);     }     return start_sticky; } @override public ibinder onbind(intent intent) {     return null; } @override public boolean onunbind(intent intent) {     return super.onunbind(intent); } @override public void onrebind(intent intent) {     super.onrebind(intent); } @override public void ondestroy() {     super.ondestroy();     running = false; }  private void settimerinfo(string check) {     if(check != null)     {         log.d(tag, "check "+ check);         if (check.equals("enable"))         {         //    alarm.setalarm(service, 5000);             target = target.device;             delay_timer_time = 0;             timer_start_time = 5000;         }         if (check.equals("disable"))         {          //   alarm.setalarm(service, 600000);             myservicerunningbackground();             target = target.server;             delay_timer_time = 300000;             timer_start_time = 600000;         }     } }  private void myservicerunningbackground() {     log.d(tag,"esservcie  ");     final int restartalarminterval = 600000;     final int resetalarmtimer = 2*30*1000;     final intent restartintent = new intent(this, myservice.class);     restartintent.putextra("alarm_restart_service_died", true);     final alarmmanager alarmmgr = (alarmmanager)getsystemservice(context.alarm_service);     handler restartservicehandler = new handler()     {         @override public void handlemessage(message msg)         {             pendingintent pintent = pendingintent.getservice(getapplicationcontext(), 0, restartintent, 0);           //  alarmmgr.set(alarmmanager.elapsed_realtime, systemclock.elapsedrealtime() + restartalarminterval, pintent);             alarmmgr.setrepeating(alarmmanager.rtc_wakeup, system.currenttimemillis(), 1000 * 60 * 10, pintent);             sendemptymessagedelayed(0, resetalarmtimer);         }     };     restartservicehandler.sendemptymessagedelayed(0, 0);  }  public enum target {     server,     device } private static boolean running; public timer servicetimer; private static myservice service;  

static target target = null;

public  int delay_timer_time = 60000; public  int timer_start_time = 600000; private static final string tag = "myservice"; 

} using alarm manager well, not seems working. want 3 timertask should kept running when application in background has period of 10 mins.

to start , change mode of services 5 second 10 mins use below code activity

  private void startservices() {     log.d(tag, "startservices ");     intent intent = new intent(myactivity.this, myservice.class);     intent.putextra("current", "enable"); //disable 10 mins on ondestroy      startservice(intent); } 

thanks suggestions

you need initialize 3 timers different schedule. snippet:

servicetimer = new timer(); servicetimer.scheduleatfixedrate(new myservicemonitorpower(service, target), delay_timer_time, timer_start_time); servicetimer.scheduleatfixedrate(new myservicemonitorlocation(service, target), delay_timer_time, timer_start_time); servicetimer.scheduleatfixedrate(new myservicemonitortrafficstats(service, target), delay_timer_time, timer_start_time); 

we can know servicetimer confusing, timertask scheduled. solution is, make sure initialize 3 timers:

servicetimer = new timer(); timer2 = new timer(); timer3 = new timer();  servicetimer.scheduleatfixedrate(new myservicemonitorpower(service, target), delay_timer_time, timer_start_time); timer2.scheduleatfixedrate(new myservicemonitorlocation(service, target), delay_timer_time, timer_start_time); timer3.scheduleatfixedrate(new myservicemonitortrafficstats(service, target), delay_timer_time, timer_start_time); 

and cancel them once service destroyed:

@override public void ondestroy(){     running = false;     servicetimer.cancel();     timer2.cancel();     timer3.cancel();     super.ondestroy(); } 

using alarmmanager short time task may drains user's battery, use timer instead.
