Visual Studio 2017 - Xamarin - 文件“objDebugandroidinpackaged_resources"不存在 [英] Visual Studio 2017 - Xamarin - The file "objDebugandroidinpackaged_resources" does not exist

问题描述

我已经与这个问题斗争了 2 天，但找不到任何解决方案.

我在 Visual Studio 2017 中有一个 Xamarin Android 应用，包含三个项目:

1. Xamarin.Android 项目(主要项目)
2. Android 特定的单元测试在设备上运行 - 使用

   正如其他 SO 线程所建议的那样，我尝试卸载最新的 Android SDK Build-tools (25.0.2) 并安装了 23.0.3 版本(我的所有项目都针对 Android 6.0)，但它也没有帮助，我仍然有同样的错误.

   也许值得补充的是，当我尝试在我的应用程序中实现 RecyclerView 阅读 this 教程，他们建议在 SDK 管理器中安装 Android 7.1.1 (API 25).但是，在那之后我撤消了所有更改，甚至重新安装了 VS2017 + Xamarin.

   你知道为什么会这样吗?我真的很感激任何帮助.谢谢！

   呃，我删除了 VS2017，使用全新的 Android SDK 安装了 VS2015，但仍然是同样的问题:(

   解决方案

   我终于找到了问题所在.它与 SDK Manager 或 VS 版本的任何组件无关.

   按照 来自 developer.xamarin.com 的本地化教程，我玩了一个在我的 Android 项目中使用 Strings.xml 位.我也想从资源中获取我的活动标签，所以在 ActivityAttribute 中我定义了:

   [Activity(Label = "@string/peopleListTitle")]

   并在 Strings.xml 文件中添加此值:

   在这种情况下，我的构建失败并出现上述错误:

   文件objDebugandroidinpackaged_resources"不存在

   当我将 ActivityAttribute 更改为直接使用字符串时:

   [Activity(Label = "People List")]

   构建顺利通过.

   我设法找到了一个解决方案，但实际上我不知道为什么当我尝试使用 Strings.xml 中定义的标签文本时它没有构建.

   顺便说一句，我设法通过在 Tools -> Options -> Projects and Solutions -> Build and Run 中将构建输出详细程度设置为 Diagnostic 来找到问题所在，这给出了输出窗口中构建失败的详细信息.

   I'm fighting with that issue for 2 days already and can't find any solution.

   I have an Xamarin Android app in Visual Studio 2017 consisting of three projects:

   1. Xamarin.Android project (main one)
   2. Android-specific unit tests run on the device - project of type NUnit 3 Test Project (Android) created using NUnit Templates for Visual Studio
   3. Platform-independent unit tests project (project of type Unit Test Project (.NET Framework))

   Everything worked just fine until now. When I selected my main project as the Startup one, my app was deployed to the device/emulator. When I selected my Android-specific unit tests project, the test project was deployed and unit tests executed by nUnit Xamarin Runners on the device/emulator.

   However few days ago I updated my Visual Studio 2017 with the newest available update and now, when trying to build this android-specific unit tests project I get the following error:

   The file "objDebugandroidinpackaged_resources" does not exist.

   I've searched everywhere, including this and this SO topics. I also totally reinstalled Visual Studio 2017 and Xamarin with Android SDK included. Nothing helped. From what I read I suspect there is something wrong with the versions of Android SDK Build-tools I have installed. Here's what I have currently installed in SDK Manager:

   As the other SO threads suggested, I tried uninstalling the newest Android SDK Build-tools (25.0.2) and installed version 23.0.3 (all my projects target Android 6.0), but it also doesn't help, I still have the same error.

   Maybe it's worth adding that this issue may have started to happen when I tried to implement RecyclerView in my app reading this tutorial, where they suggested to install Android 7.1.1 (API 25) in SDK Manager. However I undoed my all changes after that and even reintalled VS2017 + Xamarin.

   Do you have any other idea why this can be ? I'd really appreciate any help. Thanks!

   EDIT 2017-04-09:

   Egh, I removed VS2017, installed VS2015 with brand new Android SDK and still the same issue :(

   解决方案

   I've finally found what was the issue. It wasn't related to any component from SDK Manager or VS version.

   Following localization tutorial from developer.xamarin.com, I played a bit with Strings.xml in my Android project. I wanted to have my Activities Label taken from resources as well, so in the ActivityAttribute I defined:

   [Activity(Label = "@string/peopleListTitle")]
   

   and added this value in Strings.xml file:

   <?xml version="1.0" encoding="utf-8"?>
   <resources>
       <!-------Other resources values ----->
       <string name="peopleListTitle">People List</string>
   </resources>
   

   In that case my build is failing with above-mentioned error:

   The file "objDebugandroidinpackaged_resources" does not exist

   When I change ActivityAttribute to use a string directly:

   [Activity(Label = "People List")]
   

   the build is passing without any issues.

   I managed to find a solution, but actually I don't know why it's not building when I try to use Label text defined in Strings.xml.

   BTW, I managed to find what's the problem by setting build output verbosity to Diagnostic in Tools -> Options -> Projects and Solutions -> Build and Run which gives a detailed info why the build failed in the Output window.
