title: Android Volley: Cannot resolve symbol Volley
body: <p>I want to use Volley to send requests from my Android app.</p>
  <p>I have included this in the build.gradle</p>
  <pre><code>dependencies {
      ...
     compile 'com.android.volley:volley:1.1.0'
  }
  </code></pre>
  <p>I want to use:</p>
  <pre><code>requestQueue queue = Volley.newRequestQueue(this);
  </code></pre>
  <p>But neither <code>requestQueue</code> nor <code>Volley</code> can be resolved.</p>
  <p>I have tried:</p>
  <pre><code>import com.android.volley;
  </code></pre>
  <p>But it also says that volley can't be resolved. I have done a gradle sync.</p>
  <p>I have not downloaded anything. My understanding is that adding Volley to build.gradle takes the place of actually downloading the library?</p>
