Visual Studio 2017-Xamarin-文件``obj \ Debug \ android \ bin \ packaged_resources''不存在 [英] Visual Studio 2017 - Xamarin - The file "obj\Debug\android\bin\packaged_resources" does not exist

问题描述

我已经为该问题奋斗了2天，找不到任何解决方案.

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

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

   按照其他SO线程的建议，我尝试卸载最新的 Android SDK构建工具(25.0.2)，并安装了23.0.3版(我的所有项目都针对Android 6.0)，但是没有帮助，我仍然有相同的错误.

   也许值得一提的是，当我尝试在应用程序中阅读本教程，他们建议在SDK Manager中安装 Android 7.1.1(API 25).但是之后，我撤消了所有更改，甚至重新安装了VS2017 + Xamarin.

   您还有其他想法吗?我真的很感谢您的帮助.谢谢！

   Egh，我删除了VS2017，并使用全新的Android SDK安装了VS2015，并且仍然遇到了同样的问题:(

   解决方案

   我终于找到了问题所在.它与SDK Manager或VS版本中的任何组件都不相关.

   按照来自developer.xamarin.com的本地化教程，我播放了在我的Android项目中与 Strings.xml 一起使用.我也想从资源中获取我的活动标签"，因此在我定义的 ActivityAttribute 中:

     [活动(标签="@ string/peopleListTitle")] 

   并将此值添加到 Strings.xml 文件中:

    <?xml version ="1.0" encoding ="utf-8"?><资源><！-------其他资源值----->< string name ="peopleListTitle">人物列表</string></resources> 

   在这种情况下，我的构建因上述错误而失败:

   文件"obj \ Debug \ android \ bin \ packaged_resources"不存在

   当我将 ActivityAttribute 更改为直接使用字符串时:

     [活动(标签=人员列表")] 

   构建顺利进行，没有任何问题.

   我设法找到一个解决方案，但实际上我不知道为什么当我尝试使用在 Strings.xml 中定义的Label文本时.

   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 来找到问题所在为什么在输出"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 "obj\Debug\android\bin\packaged_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 "obj\Debug\android\bin\packaged_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.
