升级到Xamarin Forms 2.0后的Android资源问题

史蒂夫·查德伯恩

我最近将2台计算机从Xamarin Forms 1.x升级到了2.0。一台机器就可以了，并且Xamarin Forms项目可以在Android上正常运行。另一台机器存在严重问题。

我们尝试卸载并重新安装所有东西-Xamarin，Android SDK和所有NuGet软件包-很多-但得到相同的错误消息。

它似乎与Android应用程序兼容的东西有关。

复制步骤为：

创建新的Forms 1.3项目-编译并运行-一切正常
将项目从Forms 1.3升级到2.0-问题

错误如下：

亚当

删除Resource.Designer.cs文件中的所有内容（而不是文件本身），然后重新生成。它应该为您重新生成文件，错误将消失。

第一步

确保您的Google支持包均在23.0.1.3。那是XF 2.0的要求，但它们应该已经通过XF 2.0升级进行了更新。

当其他所有方法都失败时（复制自我对另一个问题的回答）

1. Clean solution
2. update-package -reinstall (can use -project just for your Android project)
3. Delete Resource.Designer.cs contents again
4. Restart Visual Studio
5. Rebuild once again

您可能还想在这些步骤中添加抽泣，祈祷或诅咒的内容：)

最后一件事，如果那不起作用，请再次尝试相同的操作，但是这次卸载所有NuGet软件包和组件，而不是重新安装。以前对我有用。

然后确保您的缓存是干净的（C：\ Users \ yourusername \ AppData \ Local \ Xamarin）。我通常会删除此处的所有内容，以便可以对其进行重建。

不幸的是，在让Resource.Designer.cs在以前的场合下工作之前，我不得不做上面列出的所有事情。
