this code in main activity

start.setonclicklistener(new onclicklistener() {         @override         public void onclick(view v) {             if (!cd.isconnectingtointernet()) {                 showdialog(nointernetdialog);             } else if (start.gettext().tostring().equalsignorecase(getresources().getstring(r.string.start_interval))) {                  countlimit.setenabled(false);                 timelimit.setenabled(false);                  start.settext(r.string.stop_interval);                 start.refreshdrawablestate();                  // save send configuration                 savesendconfiguration();                  // show sms send                 xmlparser read = new xmlparser();                 string numberofunsend = read.getxmlfromurl(baseurl + smscount);                 status.settext(numberofunsend);                  intent downloader = new intent(context, alarmreceiver.class);                 downloader.putextra("time", timelimit.getselecteditem()                         .tostring());                 downloader.putextra("count", countlimit.getselecteditem()                         .tostring());                 downloader.addflags(intent.flag_activity_new_task);                  pendingintent = pendingintent.getbroadcast(context, 0,                         downloader, pendingintent.flag_cancel_current);                  int delay = integer.parseint(countlimit.getselecteditem()                         .tostring());                 alarmmanager.setrepeating(alarmmanager.rtc_wakeup,                         10 * 1000, delay * 60000, pendingintent);                 log.i(tag, "call main activity");             } else {                 alarmmanager.cancel(pendingintent);                 start.settext(r.string.start_interval);                 start.refreshdrawablestate();                 countlimit.setenabled(true);                 timelimit.setenabled(true);                 log.i(tag, "alarm cancel");             }          }     }); 

this alarm receiver code

public class alarmreceiver extends broadcastreceiver {  private static string tag = "saeed";  @override public void onreceive(context context, intent intent) {     intent update = new intent(context, intervalservice.class);     string time = intent.getstringextra("time");     string count = intent.getstringextra("count");     update.putextra("time", time);     update.putextra("count", count);     log.i(tag, "call service alaram receiver," + time + "," + count);     context.startservice(update); }      } 

and service code

public class intervalservice extends intentservice {  private static final string tag = "saeed";   private string baseurl; private databasehandler db; private int time; private int count;  private sharedpreferences pref; connectiondetector cd;  public intervalservice() {     super("auto interval"); }  @override protected void onhandleintent(intent intent) {     log.i(tag, "interval service implementation run");     preferencemanager.setdefaultvalues(this, r.xml.settings, false);     pref = preferencemanager.getdefaultsharedpreferences(this);     baseurl = pref.getstring("baseurl","");     db = new databasehandler(this);     cd = new connectiondetector(getapplicationcontext());     time = integer.parseint(intent.getstringextra("time"));     count = integer.parseint(intent.getstringextra("count"));     new interval().execute(); //this async task class } 

how can stop service main activity?

you can use :

intent update = new intent(context, intervalservice.class); context.stopservice(update);
