Delete alarm from AlarmManager using cancel() - Android

Question

I'm trying to create and delete an alarm in two different methods which are both called at different moments in the application logic. However when I call AlarmManager's `cancel()` method, the alarm isn't deleted. Here's my `addAlarm()` Method : ``` AlarmManager alarmManager = (AlarmManager) mContext.getSystemService(Context.ALARM_SERVICE); Intent intent = new Intent(PROX_ALERT_INTENT); intent.putExtra("ALERT_TIME", alert.date); intent.putExtra("ID_ALERT", alert.idAlert); intent.putExtra("TITLE", alert.title); intent.putExtra("GEO_LOC", alert.isGeoLoc); PendingIntent pendingIntent = PendingIntent.getBroadcast(mContext, alert.idAlert, intent, PendingIntent.FLAG_CANCEL_CURRENT); Calendar calendar = Calendar.getInstance(); calendar.setTime(alert.date); alarmManager.set(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), pendingIntent); Log.e("ADD ALERT - WithoutGeoLoc - ",alert.toString()); ``` Here's my deleteAlarm() Method : ``` AlarmManager alarmManager = (AlarmManager) mContext.getS…

Accepted Answer

Try this flag:

```
PendingIntent.FLAG_UPDATE_CURRENT
```

Instead of:

```
PendingIntent.FLAG_CANCEL_CURRENT 
```

So the PendingIntent will look like this:

```
PendingIntent pendingIntent = PendingIntent.getBroadcast(mContext, 
        alert.idAlert, intent, PendingIntent.FLAG_UPDATE_CURRENT)  
```

(Make sure that you use same `alert` object and `mContext`!)

A side note: If you want one global AlarmManager, put the AlarmManager in a static variable (and initialize it only if it's `null`).
