Question

我创建了一个简单的应用，需要在内部图片库中选择一张图片才能上传。我用XAm.plugin.media nuget尝试了一下，但是它不起作用，它给出了错误的Storage pErmission。在Android Manifest中，没有字段可以设置对内部存储的访问，而只有外部存储。如何访问Xamarin表单中的内部图像

Answer 1

在Android项目中，打开Properties文件夹下的AssemblyInfo.cs文件，添加：

// Needed for Picking photo/video
[assembly: UsesPermission(Android.Manifest.Permission.ReadExternalStorage)]

// Needed for Taking photo/video
[assembly: UsesPermission(Android.Manifest.Permission.WriteExternalStorage)]
[assembly: UsesPermission(Android.Manifest.Permission.Camera)]

// Add these properties if you would like to filter out devices that do not have cameras, or set to false to make them optional
[assembly: UsesFeature("android.hardware.camera", Required = true)]
[assembly: UsesFeature("android.hardware.camera.autofocus", Required = true)]
