我正在尝试在 Android Studio 的项目中使用 Facebook SDK。我正在遵循本教程的第 3 步。当我尝试运行该应用程序时，我收到“Gradle：任务'：FacebookApp：dexDebug'的执行失败”。错误。以下是错误时的输出

Gradle: Execution failed for task ':FacebookApp:dexDebug'.

这是 facebook 模块的 build.gradle：

buildscript {
    repositories {
        maven { url 'http://repo1.maven.org/maven2' }
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:0.5.+'
    }
}

apply plugin: 'android-library'

dependencies {
    compile files('libs/android-support-v4.jar')
}

android {
    compileSdkVersion 18
    buildToolsVersion "18.0.0"

    defaultConfig {
        minSdkVersion 7
        targetSdkVersion 16
    }

    sourceSets {
        main {
            manifest.srcFile 'AndroidManifest.xml'
            java.srcDirs = ['src']
            resources.srcDirs = ['src']
            res.srcDirs = ['res']
        }
    }
}

以及项目的 build.gradle：

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:0.5.+'
    }
}
apply plugin: 'android'

repositories {
    mavenCentral()
}

dependencies {
    compile 'com.android.support:support-v4:13.0.+'
    compile project(':libraries:facebook')
}

android {
    compileSdkVersion 18
    buildToolsVersion "18.0.0"

    defaultConfig {
        minSdkVersion 7
        targetSdkVersion 16
    }
}

难道我做错了什么？

您添加了两次 android 支持库，导致 dex 合并冲突。您的主项目使用 maven 库引用，'com.android.support:support-v4:13.0.+'而您的 Facebook 项目使用files('libs/android-support-v4.jar'). Gradle 无法解决本地 jar 文件之间的冲突，所以必须通过 maven 引用。

dependencies将 Facebook build.gradle 的部分修改为：

dependencies {
    compile 'com.android.support:support-v4:13.0.+'
}

and everything should work.

In android studio, this is how I include a support library and facebook SDK. I'm supporting API 15+.

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'fr.avianey:facebook-android-api:+@aar'
    compile 'com.android.support:support-v13:20.0.0'
    ...
}

I had a similiar issue and it was just plain oversight on my part. I had conflicting versions of com.android.tools.build:gradle:1.1.2 and 1.1.1 inside two different gradle.build files.

app/gradle.build

dependencies {
    ...
    compile 'com.android.tools.build:gradle:1.1.2'
    ...
}

top-level gradle.build

dependencies {
        classpath 'com.android.tools.build:gradle:1.1.0'
    }

I commented out the line in my project's gradle.build file, ran gradlew clean from the command line, restarted Android Studio and then order was restored in the universe.
