Xamarin MediaPlugin和不同的Android版本 [英] Xamarin MediaPlugin and different Android version

问题描述

媒体插件有问题. 如果编译目标是Android 6.0，则在我的设备V.5.0.1中的调试模式下可以正常工作.问题是，当我在发布模式下编译时，会收到此错误:

I have a problem with Media Plugin. If the compilation target is Android 6.0 it works fine in debug mode in my device that is V. 5.0.1. The problem is that when I compile in Release mode I receive this error:

> Java.Interop.Tools.Diagnostics.XamarinAndroidException: error XA2006: Could not resolve reference to 'Android.Views.KeyboardShortcutGroup' (defined in assembly 'Xamarin.Android.Support.v7.AppCompat, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null') with scope 'Mono.Android, Version=0.0.0.0, Culture=neutral, PublicKeyToken=84e04ff9cfb79065'. When the scope is different from the defining assembly, it usually means that the type is forwarded. ---> Mono.Cecil.ResolutionException: Failed to resolve Android.Views.KeyboardShortcutGroup

我已阅读如果我将编译版本更新为Android 7(API 24)，就可以解决该问题，但是在此之后，我的操作按钮将无法正常工作.当我点击按钮打开相机时，我收到此错误:

I read that the problem is solved if I will update the compile version to Android 7 (API 24), but after this my action button doesn't work fine. When I tap the button to open the camera I receive this error:

Attempt to invoke virtual method 'android.content.res.XmlResourceParser android.content.pm.ProviderInfo.loadXmlMetaData(android.content.pm.PackageManager, java.lang.String)' on a null object reference

我能做什么?谢谢！

推荐答案

我想我找到了一个解决方案: 我打开AndroidManifest.xml文件，并删除了android target版本属性.

I think I found a solution: I opened AndroidManifest.xml file and I removed the android target version property.

现在我只有:

Android编译版本:7.1 Android最低版本:4.1

Android compilation version: 7.1 Android miminal version: 4.1
