Question

我正在开发针对运行 Oreo 或 牛轧糖的Samsung Galaxy S8的应用，该应用需要在后台持续访问网络。无论应用程序处于待机或打ze模式，该应用程序均需要按 ALL 时间定期发送UDP数据包并访问用户GPS位置。我知道这不是标准程序，但是此应用程序将不在Google Play商店中，并且此网络活动对于我们应用程序的功能至关重要。

出于开发目的，我引用此文档：

https://developer.android.com/training/monitoring-device-state/doze-standby#understand_doze

并通过使用startForegroundService和startForeground使我的应用程序与Oreo兼容，如以下视频所述：

https://www.youtube.com/watch?v=Pumf_4yjTMc

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，我已关闭了所有电池优化和应用程序监视功能，并为我的应用程序选中了允许后台数据使用并在打开数据保护程序的同时允许应用程序。我还将Wi-Fi设置为“睡觉时允许”。如以下链接所述，我已经在使用ADB调试和测试应用程序待机/打ze时看到了正确的行为：

https://developer.android.com/training/monitoring-device-state/doze-standby#testing_doze_and_app_standby

但是当我实际上拔出设备并继续运行应用程序时，我看不到模拟拔出和打do /待机时显示的行为。最终，对于在后台运行的应用程序，网络活动会停止，即使，前台服务通知仍显示发送UDP数据包的服务仍处于活动状态。这使调试变得非常困难，因为我无法像文档所建议的那样强制任何导致此adb的状态。这也使我怀疑这是三星的问题，而不是Android的问题，因为我认为我已尽我所能遵守Android后台执行标准。

当我发现网络中断后能够检查系统日志时，仍然找不到任何问题的迹象，然后将电话插回去调试，可以确认我的服务流程仍然有效。这是logcat的一个片段，其中包含我的应用程序可以发送的最后一条UDP消息，然后不再发送它（在下面的跟踪中为07-09 12：10：17.206 23046-23107）：

我的主要问题是：

有没有一个原因，为什么我在使用ADB进行调试时测试休眠/待机时没有问题，但是拔出插头后却发现问题和行为发生了变化？
此应用正常运行，并且所有具有 Nougat 的 Nexus 5X 的后台网络活动均持续存在。如果该应用程序可以在Nexus 5X上正常运行，是否有理由无法在带有Nougat的S8上运行？
是否在某些地方可以描述我所看到的行为的三星Galaxy S8应用管理的明确定义？也许“三星体验”实际上并没有杀死服务，但它确实起到了其他作用，例如只要需要就扼杀网络活动。如果是这种情况，那么我就不知道了。

感谢您抽出宝贵的时间阅读并提供任何帮助！如果我可以提供其他详细信息，请在评论中告诉我。

Answer 1

在“设置”中转到Device Maintainance，然后点击Battery，如果您尚未将应用添加到“不受监视的应用”中，请添加它。

或者，点击3点菜单，然后关闭App Power monitor。也许这会让您的应用进入休眠状态。

Answer 2

我前一段时间在评论中发布了此帖子，最近的评论者提醒我，这个问题尚待解决，我认为我应该发布并接受对我有用的答案作为答案：

要解决我的问题，我最终不得不忽略电池优化， AND 将我的服务实现为前台服务， AND 确保CPU唤醒锁。

三星Galaxy S8 Android 7.0及更高版本阻止网络流量
