通常 我们大部分广播接收器的作用是为了处理我们的应用业务,

在广播机制中,Android提供了LocalBroadcastManager类来为我们应用安全保驾护航

1.创建LocalBroadcastManager:

		final LocalBroadcastManager localBroadcastManager=LocalBroadcastManager.getInstance(this);

2.通过LocalBroadcastManager发送广播

				Intent intent=new Intent();
				intent.setAction("org.lean.action.MyBroadCastReceiver");
				localBroadcastManager.sendBroadcast(intent);

3.动态注册广播接收器.(所有能接收该信息的接收器都必须为LocalBroadcastManager的实例)

		IntentFilter filter=new IntentFilter();
		filter.addAction("org.lean.action.MyBroadCastReceiver");
		localBroadcastManager.registerReceiver(new MyBroadCastReceiver(),filter);
