Question

我在Xamarin表单应用程序中使用的GeoLocator也实现了Permissions插件。但是在Android locator.GetPositionAsync(TimeSpan.FromSeconds(10));上显示异常A geolocation error occurred: Unauthorized

Manifest.xml

<uses-sdk android:minSdkVersion="15" android:targetSdkVersion="27" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
<uses-permission android:name="android.permission.SEND_SMS" />
<uses-permission android:name="android.permission.READ_PHONE_STATE" />

<uses-permission android:name="android.permission.ACCESS_MOCK_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />

我实际上今天正在尝试解决相同的问题，可能已经找到了解决方法。

首先，请确保将权限和 Location 插件安装到所有项目（包括.NET Standard共享项目和平台项目）中。

我还使用了最新的Beta版本，但这似乎引起了问题，并抛出了off异常，即使直接检查导致了Unauthorized。安装稳定版本（4.5.0.6）后，它开始按预期运行。
