Wiederholen Sie die alarm-Alltag genau (Alarm manager)

Ich ein alarm wiederhole jeden Tag.
aber es wird ein paar Sekunden oder Minuten Fehler.
Wie kann ich es genauer?

PendingIntent pendingIntent = PendingIntent.getBroadcast(getActivity(), notificationId, myIntent, PendingIntent.FLAG_UPDATE_CURRENT);
AlarmManager alarmManager = (AlarmManager)getActivity().getSystemService(Context.ALARM_SERVICE);
Calendar calendar = Calendar.getInstance();
calendar.set(Calendar.HOUR_OF_DAY, 12);
calendar.set(Calendar.MINUTE, 30);
long startUpTime = calendar.getTimeInMillis();
if (System.currentTimeMillis() > startUpTime) {
    startUpTime = startUpTime + 24*60*60*1000;
}
alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, startUpTime,  24*60*60*1000 , pendingIntent);
  • Tut myIntent zu einem Punkt WakefulBroadcastReceiver?

    versuchen Sie,

    calendar.set(Calendar.SECOND,00);

    und ändern

    alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, startUpTime,  24*60*60*1000 , pendingIntent);

    zu

    alarmManager.setRepeating(AlarmManager.RTC_WAKEUP,
            startUpTime, AlarmManager.INTERVAL_DAY, pendingIntent);
    • es funktioniert!! danke für Antwort =)
    • Sollte es reapeating everydays???
    • Ich bin neugierig, warum funktioniert das?

    1) , die Zeit die form timepicker Grundlage 

    calNow = Calendar.getInstance();
calSet = (Calendar) calNow.clone();
calSet.set(Calendar.HOUR_OF_DAY, hourOfDay);
calSet.set(Calendar.MINUTE, minute);
calSet.set(Calendar.SECOND, 0);
calSet.set(Calendar.MILLISECOND, 0);

if (calSet.compareTo(calNow) <= 0) {
    //Today Set time passed, count to tomorrow
    calSet.add(Calendar.DATE, 1);
}

    2) Set alarm für Täglich 

    Intent intent = new Intent(AddAlarmNewActivity.this, OnAlarmReceive.class);
intent.putExtra("alarmTitle", mTitle.getText().toString());
intent.putExtra("alarmId", insertedId + "");
PendingIntent pendingIntent = PendingIntent.getBroadcast(getBaseContext(), 
                                                         (int)insertedId,
                                                         intent,
                                                         PendingIntent.FLAG_UPDATE_CURRENT);

AlarmManager alarmManager = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
alarmManager.set(AlarmManager.RTC_WAKEUP, targetCal.getTimeInMillis(), pendingIntent);
alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, 
                          targetCal.getTimeInMillis(), 
                          24*60*60*1000, 
                          pendingIntent);
