Android: why the alarm notification stopped after a system reboot

I am developing an Android application that should run an alarm five times a day:
- times are not constant every day
- after the alarm goes off, I plan the next alarm.

My problem: the alarm notification works for 1 day, then it stops, and when the device reboots twice, the notification does not work, I'm not right now, if there is another way to do this, any help would be greatly appreciated!

code: I have this function to call the broadcast receiver

public static void Start_Notifying(Context context){ Calendar cal = Calendar.getInstance(); cal.setTimeInMillis(System.currentTimeMillis()); cal.add(Calendar.HOUR_OF_DAY,hour); cal.add(Calendar.MINUTE, min); Intent intent = new Intent(context, OnetimeAlarmReceiver.class); intent.setAction("START_NOTIFYING"); PendingIntent pendingIntent = PendingIntent.getBroadcast(context, notify.REQUEST_CODE, intent,0); AlarmManager alarmManager = (AlarmManager) context.getSystemService(ALARM_SERVICE); alarmManager.set(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis() , pendingIntent); SaveAlarmManager(alarmManager, pendingIntent); }

code oneTimeAlarmReciever

 public void onReceive(Context context, Intent intent) { main_menu.con = context; Notification notifyDetails; NotificationManager nm = (NotificationManager)context.getSystemService(Context.NOTIFICATION_SERVICE); notifyDetails = new Notification(R.drawable.icon,s1,System.currentTimeMillis()); PendingIntent pendingIntent = PendingIntent.getActivity(context, REQUEST_CODE, new Intent(context, prayertimes.class), 0); notifyDetails.setLatestEventInfo(context,s2+ notify.prayName , s3, pendingIntent); notifyDetails.sound=Uri.parse(PlaySound()); nm.notify(NOTIFICATION_ID, notifyDetails); main_menu.notify_me(); }

Notify_me () code

 static void notify_me() { hour =pTime.num1; min =pTime.num2; Start_Notifying(con); }

In manifest file

 <uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED"></uses-permission> <receiver class =".OnetimeAlarmReceiver" android:name="OnetimeAlarmReceiver"> <intent-filter> <action android:name="START_NOTIFYING" /> <action android:name="android.intent.action.BOOT_COMPLETED"> </action> <data android:mimeType="audio/ogg" /> </intent-filter> </receiver>

why the alarm notification stopped after a system reboot

Because emergency schedules are cleared upon reboot. If you want your alarms to go up again after a reboot, you need to implement BroadcastReceiver , which responds to the RECEIVE_BOOT_COMPLETED broadcast. The demo/ project in my WakefulIntentService repo demonstrates this.
