title: error: package com.android.volley does not exist
body: <p>I am trying to add Volley to my android project in Android Studio. 
  I downloaded Volley from git, and added it as a module using the Project Structure tool, as an android library. I fixed the errors regarding the build version an was able to compile with the new module added to my project. I started writing code and the Volley stuff even shows up in my auto complete and the packages were automatically added to my source file. </p>
  
  <p>But when I compile, i get <code>error: package com.android.volley does not exist</code></p>
  
  <p>Does anyone know what my problem is?</p>
  
  <p>here is my project structure:

  <p>here is my apps build.gradle: </p>
  
  <pre><code>    apply plugin: 'com.android.application'
  
  android {

          minSdkVersion 15
          targetSdkVersion 20
          versionCode 1

      }
      buildTypes {
          release {
              runProguard false
              proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
          }
      }
  }
  
  dependencies {
      compile fileTree(dir: 'libs', include: ['*.jar'])
