更新 xamarin.forms 和 xamarin.android答案

【问题标题】：updating xamarin.forms and xamarin.android更新 xamarin.forms 和 xamarin.android
【发布时间】：2016-07-11 21:21:16
【问题描述】：

我正在为 android 和 ios 开发 xamarin.forms

我已在 pcl 中升级到最新的 xamarin.forms 包 2.3.0.107，它工作正常 - 没有编译错误。

当我尝试将 xamarin.android 升级到相同版本时，我收到很多包错误。

我在一些帖子中看到不需要升级 xamarin.android，因为 xamarin.forms 知道采用最新/最合适的 amarin.android 包。是真的吗？

默认的 xamarin.android 来自 2016 年 1 月，这已经很老了...

这是我得到的错误列表...

您是否尝试过删除（首先将其备份到桌面或其他东西，以防万一）您的 AppData\Local\Xamarin 文件夹以及对您的项目进行清理/重建？

标签： xamarin.android xamarin.forms

【解决方案2】：

错误消息非常明确地告诉您错误是什么：

C:\Users\dev\AppData\Local\Xamarin\Android.Support.v4\21.0.3\android_m2repository_r10.zip 不是有效的 zip 文件如何修复它

请下载https://dl-ssl.google.com/android/repository/android_m2repository_r10.zip并解压到C:\Users\dev\AppData\Local\Xamarin\Android.Support.v4\21.0.3\content目录下。
