How to check if alarm is set

Question

I'm trying to check if my alarm is active or not. The alarmIsSet method will return false before the alarm is set, true when the alarm is set. So far so good, however, after the alarm i canceled alarmIsSet will continue to return true until I reboot the device. How do I fix this?

public class Alarm extends Activity {
    private Intent intent = new Intent("PROPOSE_A_TOAST");

    private void alarm (boolean activate) {
        AlarmManager am = (AlarmManager)getSystemService(Context.ALARM_SERVICE);
        PendingIntent pi = PendingIntent.getBroadcast(this, 0, intent, 0);

        if(activate == true) {
            int type = AlarmManager.ELAPSED_REALTIME_WAKEUP;
            long interval = 3000;
            long triggerTime = SystemClock.elapsedRealtime();       
            am.setRepeating(type, triggerTime, interval, pi);       
        } else {
            am.cancel(pi);
        }
    }

    private boolean alarmIsSet() {
        return PendingIntent.getBroadcast(this, 0, intent, PendingIntent.FLAG_NO_CREATE) != null;
    }
}

You just have to add

pi.cancel();

after

am.cancel(pi);
