Question

所以我遇到了一个问题，我需要能够确定HTC设备上的重启。我可以确定ShutDown，但检测完全重启似乎更具挑战性。在包含所有可能的Android权限和意图过滤器之后，我可以想到我已经得出结论，我必须遗漏HTC中的某些内容。我是否需要从HTC直接确定手机重启的权限？

<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />

...

 <!-- RECEIVERS -->
 <receiver android:name="com.smashingboxes.speed.BootReceiver"
    android:enabled="true" >
    <intent-filter>
         <action android:name="android.intent.action.BOOT_COMPLETED" />
         <action android:name="com.htc.intent.action.QUICKBOOT_POWERON" />
         <!-- Just adding this to show that I have tried everything :P -->
         <action android:name="android.intent.action.ACTION_BOOT_COMPLETED" />
    </intent-filter>
 </receiver>
 <receiver android:name="com.smashingboxes.speed.ShutdownReceiver" >
    <intent-filter>
        <action android:name="android.intent.action.ACTION_SHUTDOWN" />
        <action android:name="com.htc.intent.action.QUICKBOOT_POWEROFF" />
    </intent-filter>
</receiver>

同样，ShutdownReceiver无论是重启还是完全硬停电/上电都可以做到这一点。但BootReceiver只检测硬启动而不是HTC的重启。因此，当我重新启动时，我可以告诉我关闭，但它从未检测到BOOT_COMPLETED ...任何想法？

Answer 1

如果您可以告诉关闭事件发生，并且因为您可以订阅"ON-BOOT-COMPLETED"事件 - 为什么不将它们结合起来呢？最后一次“关闭”事件发生时，在您的应用程序SharedPrefernces上保存日期 - 在“启动完成”事件之后将日期与保存的日期进行比较 - 如果时差低于（每个说）5分钟就可以了“重启“行动。

我添加了一个适用于我的代码示例（运行android 4.3的galaxy S4）我没有主要的活动，但这些对于你的例子来说并不是必需的（只需抛出空白或将服务和引导程序复制到你的... ） -
