repeating alarm not cancelling

I have a repeating alarm set, my problem is that after cancelling it doesn't cancel (I'm checking this with Log.v()

This is how I create the alarm (in an IntentService)

AlarmManager alarms = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
Intent intentToFire = new Intent(CAlarmReceiver.ACTION_CHECK_ALARM);
PendingIntent alarmIntent = PendingIntent.getBroadcast(this, 0, intentToFire, 0);

private void rescheduleAlarm() {
    Calendar calendar = Calendar.getInstance();
    calendar.setTimeInMillis(System.currentTimeMillis());
    calendar.add(Calendar.SECOND, TIME_TO_REFRESH);
    alarms.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), CHECK_TIME,   alarmIntent);

}

Then in an Activity I have a button on upon it's click it calls this code

private OnClickListener btnCloseApplicationListener = new OnClickListener() {
    public void onClick(View v) {
        intentToCancel = new Intent(CAlarmReceiver.ACTION_CHECK_ALARM);
        alarmIntent = P开发者_Python百科endingIntent.getBroadcast(v.getContext(), 0, intentToCancel, 0);
        alarm = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
        alarm.cancel(alarmIntent);
        finish();
    }
};

After the finish() is executed I keep seeing the logs I have in DDMS window. How can I cancel it? Thanks in advance!

try using same context for the intent. The intents have to match and I think your problem is that you are using different context when trying to cancel the alarm.

alarmIntent = PendingIntent.getBroadcast(this, 0, intentToCancel, 0);
