broadcastreceiver activity:

 public void onreceive(context context, intent intent) {     toast.maketext(context, " alarm received !!! ", toast.length_long).show();  } public void cancelalarm(context context) {     intent intent = new intent(context, alarmreceiver.class);     pendingintent sender = pendingintent.getbroadcast(context, 0, intent, pendingintent.flag_update_current);     alarmmanager alarmmanager = (alarmmanager) context.getsystemservice(context.alarm_service);     alarmmanager.cancel(sender); } public void onemintalarm(context context) {     alarmmanager alarms = (alarmmanager) context.getsystemservice(context.alarm_service);     intent intent = new intent(context, alarmreceiver.class);     pendingintent recurringdownload = pendingintent.getbroadcast(context,             0, intent, pendingintent.flag_update_current);     alarms.setrepeating(alarmmanager.rtc_wakeup, system.currenttimemillis(),             1000 * 10, recurringdownload); } public void tenmintalarm(context context) {     alarmmanager alarms = (alarmmanager) context.getsystemservice(context.alarm_service);     intent intent = new intent(context, alarmreceiver.class);     pendingintent recurringdownload = pendingintent.getbroadcast(context,             0, intent, pendingintent.flag_update_current);     alarms.setrepeating(alarmmanager.rtc_wakeup, system.currenttimemillis(),             1000 * 600, recurringdownload); } public void fifteenmintalarm(context context) {     alarmmanager alarms = (alarmmanager) context.getsystemservice(context.alarm_service);     intent intent = new intent(context, alarmreceiver.class);     pendingintent recurringdownload = pendingintent.getbroadcast(context,             0, intent, pendingintent.flag_update_current);     alarms.setrepeating(alarmmanager.rtc_wakeup, system.currenttimemillis(),             1000 * 900, recurringdownload); }  public void nmintalarm(context context) {     }
