设备锁定时Altbeacon库不扫描

时间：2018-07-11 13:04:17

标签： android xamarin bluetooth beacon altbeacon

我知道关于altbeacon库存在很多问题，尤其是当它在后台运行时。但是，我找不到任何正在讨论的相同问题，因此我要提出一个新问题。

在我的android 7.1.1设备上，我正在使用版本2.7.0的altbeacon库的Xamarin绑定。当应用程序处于后台且手机未锁定时，应用程序将在配置的时间间隔后开始扫描，并找到正确的信标。但是，当手机锁定后，该应用程序将立即停止获取任何扫描结果。此外，altbeacon调试消息表明，当手机被锁定时，该库开始扫描，但是从未找到扫描结果。

该应用具有位置权限。 该问题可能源于altbeacon库的旧版本。另外，日志显示starting non-filtered scan in SCAN_MODE_LOW_LATENCY，扫描是否未过滤可能有问题吗？

请查看以下日志：

应用在后台运行但手机未锁定：
