title: Android Gradle cannot find symbol class Gson
body: <p>So I added gson-2.2.4.jar to the libs dir (I'm using android studio). My project couldn't find the Gson stuff so I added it as a library dependency to my module in the &quot;Project Structure&quot;. When I try to run the project, the build is failing with the following errors:</p>
  <pre><code>Error:(12, 23) Gradle: package com.google.gson does not exist
  Error:(37, 3) Gradle: cannot find symbol class Gson
  Error:(37, 19) Gradle: cannot find symbol class Gson
  </code></pre>
  <p>Why can't I get this working? I read elsewhere that Gradle is supposed to handle everything automatically if it's put in the lib dir.</p>
