Android – no intention to delete / replace

I set the alarm clock when I click the button

The alarm is triggered by intent

This intention gets an additional "int" passed to the broadcast receiver

The problem is that the extra intention is set at the first click of the button and will never change the other clicks:

Intent intent = new Intent(A.this, B.class);
intent.putExtra(WAKEUP_DURATION, wakeUpDuration);
PendingIntent sender = PendingIntent.getBroadcast(A.this, 0, intent, 0);

I tried to delete it in the broadcast receiver, but I had no luck:

intent.removeExtra(A.WAKEUP_DURATION);

resolvent:

Use flag when creating pendingintent_ UPDATE_ Current to update the additional content of the new intent
