xamarin - Syncfusion 在 Xamarin Forms 上迁移到 AndroidX 后导致生成错误

问题描述

将我的 Xamarin Forms 项目迁移到 AndroidX 后，我遇到了构建错误。这些错误都是几个包中的依赖引用：

Can not resolve reference: `Xamarin.Android.Support.v7.RecyclerView`, referenced by `Syncfusion.SfAutoComplete.Android`. Please add a NuGet package or assembly reference for `Xamarin.Android.Support.v7.RecyclerView`, or remove the reference to `Syncfusion.SfAutoComplete.Android`.    Voltsec.Android         
Can not resolve reference: `Xamarin.Android.Support.Compat`, referenced by `Syncfusion.SfListView.XForms.Android`. Please add a NuGet package or assembly reference for `Xamarin.Android.Support.Compat`, or remove the reference to `Syncfusion.SfListView.XForms.Android`.    Voltsec.Android

Please add a NuGet package or assembly reference for `Xamarin.Android.Support.v7.AppCompat`, or remove the reference to `Syncfusion.Buttons.XForms.Android`.  Voltsec.Android

看起来违法者是 Syncfusion、XLabs 和 Sharpnado。

我不完全确定如何解决此问题。以下是我目前在我的 Android 项目中安装的软件包：

我的目标是 Android 10.0(Q)

有什么建议可以尝试吗？

解决方案

要解决与syncfusion控件相关的编译错误，您可以在android项目中添加以下包 

Xamarin.Android.Support.v7.RecyclerView 
Xamarin.Android.Support.Compat
Xamarin.Android.Support.SwipeRefreshLayout
Xamarin.Android.Support.v7.AppCompat
