title: Resources directory error at build on xamarin
body: <p>I'm using the xamarin ide to build and output APK. 
  I need to store json configuration files, therefore i put them under Resources/config.</p>
  
  <p>The build action of the file is set to AndroidResource. When i try to build the project, i get the following error:</p>
  
  <pre><code>Invalid resource directory name "res config".
  </code></pre>
  
  <h1>Things that i tried:</h1>
  
  <ul>
  <li>Renaming the resources files involved</li>
  <li>Setting the build action of the files to None => build is working but the resources files disappear.</li>
  </ul>
  
  <p>The resources are not referenced in any way in Resource.designer.cs.</p>
  
  <p>Does anyone has an idea on how to solve this error? Thanks.</p>
