Android LocalBroadcastManager提高应用安全性

• 官方文档解释：Helper to register for and send broadcasts of Intents to local objects within your process. This is has a number of advantages over sending global broadcasts with Context.sendBroadcast(android.content.Intent):

  • You know that the data you are broadcasting won‘t leave your app, so don‘t need to worry about leaking private data.
  • It is not possible for other applications to send these broadcasts to your app, so you don‘t need to worry about having security holes they can exploit.

  • It is more efficient than sending a global broadcast through the system.

  意义是：翻译下，1、你正在发送的数据不会超出你的应用，所以不用担心泄露应用私有数据。

• 2、其他应用发送的广播不会发送到你的APP，所以你不用担心有安全性的攻击。
• 3、本地广播比全局广播更高效

创建

    final LocalBroadcastManager localBroadcastManager=LocalBroadcastManager.getInstance(this);

注册：

    IntentFilter filter=new IntentFilter();
    filter.addAction("duanqing.test.localbroadcast.fly");
    localBroadcastManager.registerReceiver(new MyBroadCastReceiver(),filter);

发送代码：

    Intent intent=new Intent();
    intent.setAction("duanqing.test.localbroadcast.fly");
    localBroadcastManager.sendBroadcast(intent);
