title: Android Studio java.lang.NoClassDefFoundError on Launch
body: <p>I added the module dependency in build.gradle and apparently Android Studio doesnt complain, no compilation errors. but when I hit "Run" to launch the app I get java.lang.NoClassDefFoundError.</p>
  
  <p>I'm using Android Studio's Gradle.</p>
  
  <p>I tried:
  gradle clean + gradle assemble and got successful build, but still failed on launch.</p>
  
  <p>my build.gradle</p>
  
  <pre><code>buildscript {
      repositories {
          mavenCentral()
      }
      dependencies {
          classpath 'com.android.tools.build:gradle:0.4'
      }
  }
  apply plugin: 'android'
  
  repositories {
      mavenLocal()
      mavenCentral()
  }
  
  dependencies {
      compile files('libs/android-support-v4.jar')
      compile group:'com.deebl', name:'deebl-client-core', version:'0.0.1-SNAPSHOT'
  }
  
  android {
      compileSdkVersion 17
      buildToolsVersion "17.0.0"
  
      defaultConfig {
          minSdkVersion 7
          targetSdkVersion 16
      }
  }
