解决方法:发生意外错误，正在初始化Android Designer. Xamarin在VS 2015中 [英] How to resolve : unexpected error occured Initializing Android Designer" in VS 2015 with Xamarin
问题描述
使用Xamarin和VS 2015 Pro启动新PC时，出现以下错误:
Bringing up a new PC with Xamarin and VS 2015 Pro I received the following error:
尝试初始化Android Designer时发生意外错误. 请验证Android SDK路径和Java Development Kit路径 在工具->选项-> Xamarin-> Android设置菜单上.请查看日志 有关更多详细信息.
An unexpected error occurred trying to initialize Android Designer. Please verify the Android SDK path and the Java Development Kit path on Tools->Options->Xamarin->Android Settings menu. Please see the logs for more details.
我已验证SDK的安装正确. VS没有生成任何类型的活动日志，因此我认为该日志必须位于其他位置.任何人都知道我在哪里可以找到此日志，以查找有关错误的更多信息?
I verified the SDK's are installed correctly. VS didn't generate any kind of Activity Log so I believe the log must lie elsewhere. Anyone know where I can find this log to find out more about what is wrong ?
推荐答案
我遇到了与上述问题完全相同的问题(在装有新Visual Studio的新PC上)，并且99.9％的人确定答案是如何应用更新.或者，更重要的是，当您认为它们是没有被应用时.
I had exactly the same problem described (on a new PC, with a new Visual Studio install) and am 99.9% sure the answer is in how updates are applied. Or, more importantly, how they aren't being applied when you think they are.

转到工具|选项| Xamarin |其他，在Xamarin下进行Visual Studio更新，现在检查STABLE更新.确保您至少运行4.2.0.680.当更新程序正在运行时，您将不得不在后台关闭Visual Studio，它会警告您. 从Visual Studio卸载和安装跨平台开发工具并没有为我应用此更新.我不得不强行解决这个问题.
现在，如前所述，转到工具"，Android SDK Manager.我注意到我的"Android SDK工具"和跨平台工具"已经过时，并且有可用的更新.我接受并将更新应用到版本24.4.1. 与我同在，这就是棘手的地方-仍然无法正常工作.
Now, as mentioned earlier, go to Tools, Android SDK Manager. I noticed my "Android SDK Tools" and "Cross Platform Tools" were out of date and updates were available. I accepted and applied the updates to version 24.4.1. BEAR WITH ME, THIS IS WHERE IT GETS TRICKY--it still didn't work.
返回到工具，Android SDK Manager .我立即注意到，即使我刚刚应用了"Android SDK工具"的最新更新(24.4.1)，现在仍然可以使用新版本(25.2.2)以及其他17个更新.我全部接受了.
Go back to Tools, Android SDK Manager. I immediately noticed that even though I'd just applied the latest update for "Android SDK Tools", (24.4.1), a new version (25.2.2) was now available, along with 17 other updates. I accepted them all.
宾果.在曾经有烦人的错误消息，空白的设计图面和带有悲伤的无可用控件"消息的工具箱的地方，现在有附加的屏幕快照-设计图面，可以在其中看到.axml的可视化表示形式，以及一个我可以从中拖放控件的工具箱，它们实际上会显示在我的Samsung平板电脑上.
Bingo. Where I once had the annoying error message and an empty design surface and an empty toolbox with the sad "no usable controls" message, I now have the attached screen snapshot--a design surface where I can see a visual representation of my .axml, and a toolbox from which I can drag and drop controls and they actually show up on my Samsung tablet.
抱歉，太冗长了.我在此问题上花费了数小时，并认为其他人可能会喜欢另一种可行的解决方案.
Sorry so verbose. I lost hours on this problem and thought others might appreciate another working solution.
