AltBeacon 应用程序在几分钟后重新启动

我的应用程序遇到一些问题。我在禁用 RegionBootstrap 并通过 System.exit(0) 关闭应用程序后，我的应用程序在几分钟后（通常是 3-4 分钟）会自行重新启动。

这是我每次重新启动应用程序时发现的 Logcat 行：

可能是什么原因？ OnePlusSmartBoostManager 是问题的根源吗？如何避免我的应用程序以这种方式重新启动？

这些是重启前几分钟 logcat 中的其他行：

一旦您开始测距或监控，即使在后台甚至应用程序终止后，库也会尝试使其继续运行。该库这样做是因为当内存不足或用户在前台使用完应用程序时，操作系统或用户通常会终止应用程序。

自动重启是通过多种技术完成的，包括 5 分钟的 AlarmManager 计时器和 START_STICKY 服务标志 (Android 4.3-7.x) 以及 15 分钟的 JobService (Android 8+)。这允许在后台扫描信标，以便在发现时自动启动应用程序逻辑，并且默认情况下会使用最少的系统资源。

该应用程序自动重新启动，因为System.exit(0)有效地使您的应用程序崩溃，使库扫描保持启用状态。

如果您不想发生这种情况，则必须首先彻底关闭扫描。停止测距和/或监视，然后取消与 BeaconManager 的绑定（如果您绑定到它），或者在 RegionBootstrap 上调用disable()（如果您使用它来启动扫描）。
