Unexpected Top-Level Exception in android-support-v4.jar

android, android-appcompat, android-studio, facebook-android-sdk, gradle

Solution

I found the problem :

AppProject/settings.gradle

include ':libraries:facebook', ':app'

AppProject/libraries/facebook/build.gradle

apply plugin: 'android-library'

dependencies {
    compile 'com.android.support:support-v4:18.0.0'
}

AppProject/app/build.gradle

apply plugin: 'android'

dependencies {
    compile 'com.android.support:support-v4:18.0.0'
    compile 'com.android.support:appcompat-v7:18.0.+'
    compile 'com.google.android.gms:play-services:3.1.36'

    compile project(':libraries:facebook')
    compile files('libs/android-async-http-1.4.3.jar')
    compile files('libs/gson-2.2.4.jar')
    compile files('libs/libGoogleAnalyticsV2.jar')
    compile files('libs/universal-image-loader-1.8.4.jar')
    compile files('libs/urbanairship-lib-3.0.0.jar')
}

Problem

I have a problem when I want to compile my app: UNEXPECTED TOP-LEVEL EXCEPTION: java.lang.IllegalArgumentException: already added` It seems to be a error with android-support-v4.jar. In my project I have 3 libraries: appcompat, facebook, google_play_services. My gradle files: AppProject/settings.gradle ``` include ':libraries:google_play_services', ':libraries:appcompat', ':libraries:facebook', ':app' ``` AppProject/build.gradle : ``` buildscript { repositories { mavenCentral() } dependencies { classpath 'com.android.tools.build:gradle:0.5.+' } } ``` AppProject/app/build.gradle: ``` apply plugin: 'android' dependencies { compile project(':libraries:appcompat') compile project(':libraries:facebook') compile project(':libraries:google_play_services') compile files('libs/android-async-http-1.4.3.jar') compile files('libs/gson-2.2.4.jar') compile files('libs/libGoogleAnalyticsV2.jar') compile files('libs/universal-image-loader-1.8.4.jar') compile files('libs/urbanairship-lib-3.0.0.jar') } ``` AppProject/libraries/appcompat/build.gradle: ``` apply plugin: 'android-library' dependencies { compile files('libs/android-support-v4.jar') compile files('libs/android-support-v7-appcompat.jar') } ``` AppProject/libraries/facebook/buidle.gradle: ``` apply plugin: 'android-library' dependencies { compile files('libs/android-support-v4.jar') } ``` AppProject/libraries/google_play_services/buidle.gradle: ``` apply plugin: 'android-library' dependencies { compile files('libs/google-play-services.jar') } ``` But when I compile it, this error appears: ``` Output: UNEXPECTED TOP-LEVEL EXCEPTION: java.lang.IllegalArgumentException: already added: Landroid/support/v4/app/NotificationCompatIceCreamSandwich; ``` Can you help me?
