## Broadcast流程

注意：VA对client的xml中定义的receiver（静态广播接收器）做了处理，详细参考VAInstall流程图。

### 标准Broadcast发送/接收

### VA中Broadcast发送/接收

### VA中动态Broadcast注册

动态注册Broadcast，最终都会调用ActivityManagerNatvie#registerReceiver方法，因此VA中hook了这个方法然后改造IntentFilter的ACTION字段，具体改造方法与静态广播接收器的方式相同。然后创建一个新的`IIntentReceiver$Stub`对象，传递给AMS。也就是所谓静态代理方式。

代码：RegisterReceiver.java

请参考下面类结构图。
