I have the code :
public void AlarmStart() {
Calendar cal = Calendar.getInstance();
cal.add(Calendar.MINUTE, 5);
Intent intent = new Intent(MainN
I think that you don't need any reference to an Activity in the NotifierHelper. Use the Context (which Activity is a subclass of), eg:
public static void sendNotification(Context caller, ...
Such methods as getSystemService(), etc.. are actually exposed by Context.
And since you get passed a Context in AlarmReceiver.onReceive(), you can pass it on.
