三星GalaxyAndroid7.0及以上停止网络流量
三星GalaxyAndroid7.0及以上停止网络流量
提问于 2018-07-09 16:56:55
我正在开发一款三星GalaxyS8的应用程序，它运行着Oreo或Nougat，后台需要不断的网络访问。该应用程序需要发送UDP数据包和访问用户GPS位置在的所有时间在所有的时间，无论是应用-待机或打瞌睡模式。我知道这是不标准的，但这个应用程序不会出现在谷歌的游戏商店里，这个网络活动对我们的应用程序的功能至关重要。
为发展目的，我谨提及这份文件：
并通过使用startForegroundService和startForeground使我的应用程序Oreo兼容，视频如下所示：
我还添加了以下代码以选择退出电池优化：
Intent intent = new Intent();
String packageName = this.getPackageName();
PowerManager pm = (PowerManager) this.getSystemService(Context.POWER_SERVICE);
if (!pm.isIgnoringBatteryOptimizations(packageName)){
intent.setAction(Settings.ACTION_REQUEST_IGNORE_BATTERY_OPTIMIZATIONS);
intent.setData(Uri.parse("package:" + packageName));
this.startActivity(intent);
}此外，我已经关闭了所有电池优化和应用程序监控，并为我的应用程序检查允许背景数据使用和允许应用程序，而数据保存。我还把Wi设置为“睡觉时允许”。在使用亚行调试和测试app-备用/打瞌睡时，我看到了正确的行为，如本链接所述：
但是，当我实际拔掉设备并继续运行应用程序时，我看不到模拟拔出和打瞌睡/备用时所显示的行为。最终，对于运行在后台的应用程序，网络活动停止了，，尽管前台服务通知仍然显示发送UDP数据包的服务仍然处于活动状态。这使得调试变得非常困难，因为我不能强制任何状态导致这种情况，正如docs所建议的那样。这也让我怀疑这是三星的问题，而不是Android的问题，因为我觉得我已经按照我所知道的最好的Android后台执行标准。
当我能够在注意到网络中断后检查系统logcat时，我仍然找不到任何错误的迹象，而且当我将手机插入调试时，我可以确认我的服务流程仍然是活的。下面是logcat的一个片段，它包含了我的应用程序能够在它不再发送之前发送的最后一条UDP消息(在下面的跟踪中，07-09 12:10:17.206 23046-23107 )：

07-09 12:10:28.674 3702-3974/? D/SamsungAlarmManager: setExact Listener我的主要问题是：
- 为什么我在使用亚行调试时在测试打瞌睡/备用时没有发现任何问题，但在拔出电源后会看到问题和行为改变呢？
- 这个应用程序的功能正确，所有的背景网络活动持续为一个Nexus5X与努格特。当该应用程序在Nexus5X上按预期功能运行时，它不会在S8上运行，这有什么原因吗？
- 三星银河S8应用程序管理是否有一个清晰的定义来描述我所看到的行为？也许“三星体验”并没有真正扼杀服务，但它确实起到了其他一些神奇的作用，比如只要它想要的时候就简单地扼杀网络活动。如果是这样的话我就不知道了。
感谢您抽出时间阅读并提供任何帮助！如果我能提供任何其他细节，请在评论中告诉我。

转到“设置中的Device Maintainance”，然后点击Battery，如果您还没有在“”未监视的应用程序中添加应用程序，那么就添加它。
或者，点击3点菜单并关闭App Power monitor.也许这会让你的应用程序睡着。

不久前，我在一篇评论中发表了这篇文章，最近一位评论者提醒我，这个问题是开放的，我想我应该发帖并接受对我有用的答案：
为了解决我的问题，我不得不忽略电池优化，和将我的服务实现为前台服务，和保护CPU唤醒。
