Android BroadcastReceiver

        <receiver
            android:name=".MyReceiver"
            android:enabled="true"
            android:exported="true">
            <!--<intent-filter android:priority="11">-->
            <intent-filter >
                <action android:name="com.grandkai.learnbroadcastreceiver.intent.action.MyReceiver" />
            </intent-filter>

        </receiver>

        <receiver
            android:name=".MyReceiver2"
            android:enabled="true"
            android:exported="true">
            <!--<intent-filter android:priority="10">-->
            <intent-filter >
                <action android:name="com.grandkai.learnbroadcastreceiver.intent.action.MyReceiver" />
            </intent-filter>
        </receiver>

不指定优先级的情况下，先注册的BroadcastReceiver先执行，不想继续向下执行其他BroadcastReceiver需要在onReceive中执行abortBroadcast()；同时启动广播时需要发送有序广播sendOrderedBroadcast(..);
