android set zukünftige benachrichtigung alarmmanager ausgabe nicht feuer

Question

Meine anwendung erfordern zukünftige benachrichtigung zu unterschiedlichen zeitpunkten. Also habe ich unten Code mit Hilfe von this link implementiert.

Aber am Ende meiner Schlussfolgerung ist dieser Code nicht alle Benachrichtigungen ausgelöst, manchmal wird keiner der zukünftigen Benachrichtigung ausgelöst werden.

Anwendung ist Client-Server-Basis-App so Datum-Uhrzeit vom Server erhalten. Beispiel ist wie folgt.

SimpleDateFormat simpleDateFormatDateTime = new SimpleDateFormat("yyyy-MM-dd hh:mm:ss", Locale.US); 
Date eventAlertDateTime = simpleDateFormatDateTime.parse("2016-09-08 16:41:00.0"); 
Calendar calendar = Calendar.getInstance(); 
calendar.setTime(eventAlertDateTime); 
setInternalBroadcastNotification(eventAlertDateTime, "Your brunch is readyon 2nd floor."); 
eventAlertDateTime = simpleDateFormatDateTime.parse("2016-09-09 16:41:00.0"); 
calendar.setTime(eventAlertDateTime); 
setInternalBroadcastNotification(eventAlertDateTime, "Your brunch is readyon 2nd floor.");

public void setInternalBroadcastNotification(Date eventAlertDateTime, String eventNotificationMessage) { 
try { 
    Calendar calendar = Calendar.getInstance(); 
    calendar.setTime(eventAlertDateTime); 

    long timeDifference = calendar.getTimeInMillis() - Calendar.getInstance().getTimeInMillis(); 
    if (timeDifference > 0) { 
     Intent receiverServiceIntent = new Intent(mContext, InternalBroadcastReceiver.class); 
     receiverServiceIntent.putExtra("eventNotificationMessage", eventNotificationMessage); 

     PendingIntent pendingIntent = PendingIntent.getService(mContext, (int) eventAlertDateTime.getTime(), receiverServiceIntent, PendingIntent.FLAG_UPDATE_CURRENT); 

     AlarmManager alarmManager = (AlarmManager) mContext.getSystemService(Context.ALARM_SERVICE); 
     if (android.os.Build.VERSION.SDK_INT < Build.VERSION_CODES.KITKAT) { 
      alarmManager.set(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), pendingIntent); 
     } else { 
      alarmManager.setExact(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), pendingIntent); 
     } 
    } 
} catch (Exception exception) { 
    exception.printStackTrace(); 
} 
}

Answer 1

ändern

PendingIntent pendingIntent = PendingIntent.getService(mContext, (int) eventAlertDateTime.getTime(), receiverServiceIntent, PendingIntent.FLAG_UPDATE_CURRENT); 

Um

Random generator = new Random(); 
int n = 10000; 
n = generator.nextInt(n); 
PendingIntent pendingIntent = PendingIntent.getService(mContext, n , receiverServiceIntent, PendingIntent.FLAG_UPDATE_CURRENT); 

Und

Gehen Sie Ihre Zukunft Zeit wie folgt aus:

alarmManager.set(AlarmManager.RTC_WAKEUP, eventAlertDateTime.getTime(), pendingIntent);
