Xamarin 表單如何從圖庫中選擇圖像

Question

我創建了一個簡單的應用程序，我需要在內部圖庫中選擇一個圖像才能上傳它。 我用 XAm.plugin.media nuget 嘗試過，但它不起作用，它給出了錯誤存儲許可。 在Android Manifest中，沒有設置訪問內部存儲的字段，它只有外部存儲如何在Xamarin表單中訪問內部圖像

Answer 1

在Android項目中，打開Properties文件夾下的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)]
