  <p>EDIT: gradle file added</p>
  
  <p>this is my gradle:</p>
  
  <pre><code>buildscript {
      repositories {
          mavenCentral()
      }
      dependencies {
          classpath 'com.android.tools.build:gradle:0.7.+'
      }
  }
  apply plugin: 'android'
  
  android {
      compileSdkVersion 15
      buildToolsVersion '19.0.1'
  
      defaultConfig {
          minSdkVersion 15
          targetSdkVersion 19
          versionCode 1
          versionName "1.0"
      }
      buildTypes {
          release {
              runProguard false
              proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
          }
      }
  }
  
  dependencies {
      compile 'com.android.support:support-v4:+'
      compile 'com.google.android.gms:play-services:4.0.30'
      compile 'de.keyboardsurfer.android.widget:crouton-library:1.8.2'
      compile files('libs/ActiveAndroid.jar')
  }
  </code></pre>
  
  <p>if i use all three without "de.keyboardsurfer.android.widget:crouton-library:1.8.2"
  then it all works ok.</p>
