BroadcastReceiver的优先级

有多个BroadcastReceiver的时候设置优先级，可以在manifest文件中设置优先级，优先级越高，数字越大：
<receiver
android:name=".MyReceiver"
android:enabled="true"
android:exported="true">
<intent-filter android:priority="9">
<action android:name="com.chenshipeng.learnbroadcastreceiver.intent.action.MyReceiver" />
</intent-filter>
</receiver>
<receiver
android:name=".MyReceiver1"
android:enabled="true"
android:exported="true">
<intent-filter android:priority="8">
<action android:name="com.chenshipeng.learnbroadcastreceiver.intent.action.MyReceiver" />
</intent-filter>
</receiver>
在高优先级的BroadcastReceiver中可以中断后续的broadcastReceiver：
public class MyReceiver extends BroadcastReceiver {

public  static final  String ACTION = "com.chenshipeng.learnbroadcastreceiver.intent.action.MyReceiver";
@Override
public void onReceive(Context context, Intent intent) {


//        System.out.println("接收到了消息,消息的内容是："+intent.getStringExtra("data"));
    System.out.println("MyReceiver接收到了消息");
    abortBroadcast();
}

}
当然这只有当发送消息的时候使用的是：
sendOrderedBroadcast(i,null);
而不是
sendBroadcast(i);的时候。
