I am developing an android application that should fire an alarm five times a day:
- the times in each day is not constant
- after the alarm is fired I will schedule the next alarm.
My problem is : the alarm notification works for 1 day then it stops and also when the device is rebooted twice the notification doesn't work , I don't now if there is another way to do that , any help will be very appreciated!
Code: I have this function to call the broadcast reciever
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);
}
the code of 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();
}
The code of notify_me()
static void notify_me() {
hour =pTime.num1;
min =pTime.num2;
Start_Notifying(con);
}
In the 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 did the Alarm notification stop after system reboot
Because alarm schedules are cleared on a reboot. If you want to have your alarms pick up again after a reboot, you will need to implement a BroadcastReceiver
that responds to the RECEIVE_BOOT_COMPLETED
broadcast. The demo/
project in my WakefulIntentService
repo demonstrates this.
