title: Error when building Cordova app using Crosswalk WebView plugin
body: <p>When I try to build my Cordova app using Crosswalk WebView plugin I always get the following error:</p>
  
  <blockquote>
    <p>1>  :processArmv7DebugResources FAILED</p>
  </blockquote>
  
  <p>And also:</p>
  
  <blockquote>
    <p>You may not have the required environment or OS to build this project</p>
  </blockquote>
  
  <p>I've opened Android SDK manager and I've the following SDKs already installed in my system: API Level 14, 15, 19 and 21.</p>
  
  <p>Also, I've set minimum/target SDK version to 15.</p>
  
  <p>Sadly, I can't figure out what's not being installed to fix the issue. </p>
  
  <p>I'm using Cordova 5.1.1 and latest Crosswalk 1.2.0 plugin.</p>
  
  <p>Also, I've tried to run <code>cordova build android --debug</code> to get any clue about what's missing in my development environment with no luck.</p>
