title: Android Studio can't find library classes after Gradle build
body: <p>I'm trying to add a <code>.jar</code> library to my project into the <code>/libs</code> folder. Here is my <code>grade.build</code>:</p>
  
  <pre><code>    buildscript {
          repositories {
              mavenCentral()
          }
          dependencies {
              classpath 'com.android.tools.build:gradle:0.4'
          }
      }
      apply plugin: 'android'
  
      dependencies {
          compile files('libs/android-support-v4.jar', 'libs/java-api-wrapper-1.2.0-all.jar')
      }
  
      android {
          compileSdkVersion 17
          buildToolsVersion "17.0.0"
  
          defaultConfig {
              minSdkVersion 15
              targetSdkVersion 16
          }
      }
  </code></pre>
  
  <p>After I add that, I build my project and there are no errors. But when I try to use the class in my code <code>private ApiWrapper wrapper</code>, I get an error:</p>
  
  <pre><code>Gradle: error: cannot find symbol class ApiWrapper
  </code></pre>
  
  <p>I can't quite find where the error is. Is my <code>grade.build</code> not ok, or am I supposed to build it some other way?</p>
