Answer 1

For anyone still looking around. I generated a timestamp and used it as the id.

import java.util.Date;
import java.util.Locale;

public int createID(){
   Date now = new Date();
   int id = Integer.parseInt(new SimpleDateFormat("ddHHmmss",  Locale.US).format(now));
   return id;
}

Use it like so

int id = createID();
mNotifyManager.notify(id, mBuilder.build());
