发送有序广播

程序启动后，单击“发送有序广播”按钮，发出一条广播事件，此时观察LogCat窗口下的提示信息，输出什么？(见上图00)
若将广播接收者MyBroadcastReceiverTwo优先级同样设置为1000，并将MyBroadcastReceiverTwo注册在MyBroadcastReceiverOne前面，再来运行程序，观察结果（见上图01）
修改MyBroadcastReceiverTwo如下，观察结果（见上图02）
public class MyBroadcastReceiverTwo extends BroadcastReceiver {
public MyBroadcastReceiverTwo() {
}

@Override
public void onReceive(Context context, Intent intent) {
Log.i("MyBroadcastReceiverTwo", "two自定义的广播接受者,接受到了求救广播事件");
abortBroadcast（）;  //拦截有序广播
Log.i("MyBroadcastReceiverTwo", "我是two,广播被我终结了");

}
}
