Unity - Android 10 - BLE 蓝牙 - 后台位置
Unity - Android 10 - BLE Bluetooth - Background location
我正在开发一个使用蓝牙扫描服务的 Unity Android 项目。当我升级到 Android 10 (API 29) 时,蓝牙连接开始出现问题。我正在从这个 post(下面的 link)中寻求帮助,其中提到 Android 10 之后需要包含 BACKGROUND_LOCATION
权限。
Android 10 not working with BLE Bluetooth scanning
在 Unity 中,我使用权限实用工具编写了一些代码
if (AndroidRuntimePermissions.CheckPermission(Permission.CoarseLocation) != AndroidRuntimePermissions.Permission.Granted)
{
AndroidRuntimePermissions.RequestPermission(Permission.CoarseLocation);
}
Permission
class 是来自 UnityEngine.Android
的内部 class,它似乎没有后台位置权限。见下文,
using UnityEngine.Scripting;

如果您解决了这个问题,请告诉我。非常感谢您的帮助。谢谢。
这只是一个字符串,因此请将您想要的权限 class 传递给它。
Permission.RequestUserPermission( "android.permission.ACCESS_BACKGROUND_LOCATION" );
我用它来确保获得位置权限请求的所有三个选项(“始终”、“仅在打开时”、“从不”)
