Question

我遇到了AltBeacon Android Beacon Library的问题，我已经设置了所有权限（BLUETOOTH, BLUETOOTH_ADMIN, ACCESS_FINE_LOCATION, ACCESS_COARSE_LOCATION），但由于某些原因我的应用程序无法检测到任何信标（尝试了几个不同的信号）。我正在使用三星Galaxy Tab与android 6.0.1。当我运行我的应用程序时，我收到以下消息：

    }

    beaconManager = BeaconManager.getInstanceForApplication(this);

    beaconManager.bind(this);

我遇到了同样的问题，看起来在这里我们可以找到解决方案：https://github.com/AltBeacon/android-beacon-library/issues/412 它声明应用程序需要配置为设置中的设置 - ＆gt;位置（高精度或省电模式）
