title: Visual Studio 2017 - Xamarin - The file "obj\Debug\android\bin\packaged_resources" does not exist
body: <p>I'm fighting with that issue for 2 days already and can't find any solution.</p>
  
  <p>I have an Xamarin Android app in Visual Studio 2017 consisting of three projects:</p>
  
  <ol>
  <li>Xamarin.Android project (main one)</li>
  <li>Android-specific unit tests run on the device - project of type <code>NUnit 3 Test Project (Android)</code> created using <a href="https://marketplace.visualstudio.com/items?itemName=NUnitDevelopers.NUnitTemplatesforVisualStudio" rel="noreferrer">NUnit Templates for Visual Studio</a></li>
  <li>Platform-independent unit tests project (project of type <code>Unit Test Project (.NET Framework)</code>)</li>
  </ol>
  
  <p>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.</p>
  
  <p>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 <strong>I get the following error</strong>:</p>
  
  <p><code>The file "obj\Debug\android\bin\packaged_resources" does not exist.</code></p>
  
  <p>I've searched everywhere, including <a href="https://stackoverflow.com/questions/32292577/android-app-compile-not-generating-package-resources">this</a> and <a href="https://stackoverflow.com/questions/38398188/xamarin-android-can-not-debug">this</a> 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 <em>Android SDK Build-tools</em> I have installed. Here's what I have currently installed in SDK Manager:

  <p>As the other SO threads suggested, I tried uninstalling the newest <em>Android SDK Build-tools (25.0.2)</em> 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.</p>
  
  <p>Maybe it's worth adding that this issue may have started to happen when I tried to implement RecyclerView in my app reading <a href="https://developer.xamarin.com/guides/android/user_interface/recyclerview/" rel="noreferrer">this</a> tutorial, where they suggested to install <em>Android 7.1.1 (API 25)</em> in SDK Manager. However I undoed my all changes after that and even reintalled VS2017 + Xamarin.</p>
  
  <p>Do you have any other idea why this can be ? I'd really appreciate any help. Thanks!</p>
  
  <p><strong>EDIT 2017-04-09:</strong></p>
  
  <p>Egh, I removed VS2017, installed VS2015 with brand new Android SDK and still the same issue :(</p>
