BroadcastReceiver 实现跨进通信（APP与APP

1：新建工程ReceiverPorject

 1）定义接收器：新建MyBroadcastReceiver类继承BroadcastReceiver

public class MyBroadcastReceiver extends BroadcastReceiver { 

    @Override 

 publicvoid onReceive(Context context, Intent intent) { 

      String action="发送广播哪里定义的action"

      if(action.equals(intent.getAction())){

             //定义接收到广播后的操作  

       }

     } 

} 

2)在清单文件中注册广播（也可以动态注册）

<receiver android:name=".MyBroadcastReceiver">

          <intent-filter> 

              <action android:name="发送广播哪里定义的action" /> 

          </intent-filter> 

</receiver>

2：新建工程SendPorject，在需要发送广播的地方

Intent intent =new Intent("发送广播定义的action"); 

sendBroadcast(intent);
