Android-本地廣播提高安全性

通常 我們大部分廣播接收器的作用是為了處理我們的應用業務,

在廣播機制中,Android提供了LocalBroadcastManager類來為我們應用安全保駕護航

1.創建LocalBroadcastManager:

		final LocalBroadcastManager localBroadcastManager=LocalBroadcastManager.getInstance(this);

2.通過LocalBroadcastManager發送廣播

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

3.動態注冊廣播接收器.(所有能接收該信息的接收器都必須為LocalBroadcastManager的實例)

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