小贝子编程

扫描作业在 15 分钟后继续正常调用，并在区域匹配时停止



根据我在 AltBeacon 库文档中的理解，ScanJob 应该在与应用程序最后一次交互 15 分钟后停止调用。

我已经开始监视和范围某些区域，并且已禁用所有信标， 因此没有检测到信标.启动应用程序后，我已经杀死了它，并且在日志中我看到即使在 15 分钟后也会连续调用 ScanJob。

如果我没有与手机交互并且没有任何与受监控区域匹配的信标，它不应该在 15 分钟后停止吗？

另外， 当我连接信标时， 它被检测到， 但随后扫描作业停止调用.

这是预期的行为吗？我可能配置错误了某些东西吗？

编辑以添加一些代码和信息

我正在尝试的是使连续后台扫描不绑定到活动。因此，我将开始测距和监视所需的所有代码放在MyApplication从Application扩展的类中。

}

监控似乎工作正常，因为我在打开信标时接到电话并首次检测到.但是在我唤醒手机之前不会调用范围。

很抱歉听到这个麻烦。 目前还不清楚是什么原因导致扫描以意外的间隔发生，但我怀疑这可能与双重绑定有关。

一些提示：

  • 如果使用区域引导程序，请不要手动绑定，因为它在内部执行此操作。 删除：

    beaconManager.bind(this);

  • 同时删除以下方法，将范围通知程序设置移动到 onCreate

    onBeaconServiceConnect

  • 在通过 RegionBootstrap 绑定之前，必须设置配置更改。 因此，请将这些行移到该行上方：

    beaconManager.setBackgroundScanPeriod(3000l);
beaconManager.setBackgroundBetweenScanPeriod(15000l);
beaconManager.setRegionStatePersistenceEnabled(false);

  • 了解，在后台的Android 8上无法遵守上述后台扫描周期，操作系统将把扫描周期限制为~15秒。 我会一次在后台扫描超过 3 秒。 请考虑保留默认值 10 秒。
