文档只提到“该顺序仅适用于同步消息;异步消息将被忽略。” 这是否意味着 Android 仅查看“有序广播”的优先级?
<receiver android:name=".receivers.PhoneStateReceiver" >
<!-- TODO it's supposed to be an un-ordered broadcast -->
<intent-filter android:priority="99999999999" >
<action android:name="android.intent.action.PHONE_STATE" />
</intent-filter>
</receiver>
...使上述“优先级”无用?
