TaskStackBuilder stackBuilder = TaskStackBuilder.create(con);
stackBuilder.addParentStack(MainActivity.class);
stackBuilder.addNextIntent(resultIntent);
stackBuilder.getPendingIntent...

这样的模式为了创建完整的Activity队列，可能导致并不会调用已经存在的activity，而是重新创建，要想push消息等只调起已经存在的activity不要重新创建需要下面这样写：
PendingIntent resultPendingIntent = PendingIntent.getActivity(con, 0, resultIntent, PendingIntent.FLAG_UPDATE_CURRENT);
PendingIntent.FLAG_UPDATE_CURRENT比较关键，如果不设置此值，会导致Intent消息不会更新到当前activity
