为什么没有调用广播接收器的onreceive（）方法？

Question

我是android开发的初学者。我正在尝试制作一个SMS计划程序。我的应用程序的广播接收器的onReceive（）方法没有被调用？下面给出了我的源代码。我看了一些其他的链接，像基本的Android报警应用程序，广播接收器的onReceive（）方法没有被调用请，我想知道我哪里做错了。提前谢谢。

问题是创建意图时,要这样做：

mesg_intent = new Intent(this, Alarmservice.class);
mest_intent.putExtras(bundle);
pending_intent = PendingIntent.getBroadcast(this, 0, mesg_intent, PendingIntent.FLAG_UPDATE_CURRENT);
