我正在尝试在Android Studio的项目中使用Facebook SDK。我正在关注this教程的第3步。当我尝试运行应用程序时,我得到一个“Gradle:执行失败的任务':FacebookApp:dexDebug'。”错误。如果错误
,下面是输出Gradle: Execution failed for task ':FacebookApp:dexDebug'.
> Failed to run command:

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']
}
}
}
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
}
}
我做错了吗?

你要两次添加android支持库,导致dex合并冲突。您的主项目是指带有'com.android.support:support-v4:13.0.+'
的maven库,而您的Facebook项目使用files('libs/android-support-v4.jar')
引用它。 Gradle无法解决本地jar文件之间的冲突,因此您必须通过maven引用它们。
将Facebook build.gradle的dependencies
部分修改为:
dependencies {
compile 'com.android.support:support-v4:13.0.+'
}
一切都应该有效。

在android studio中,这就是我包含支持库和facebook SDK的方式。我支持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'
...
}

我有一个类似的问题,这只是我的疏忽。我在两个不同的gradle.build文件中有com.android.tools.build:gradle:1.1.2和1.1.1的冲突版本。
应用程序/ gradle.build
dependencies {
...
compile 'com.android.tools.build:gradle:1.1.2'
...
}
顶级gradle.build
dependencies {
classpath 'com.android.tools.build:gradle:1.1.0'
}
我在项目的gradle.build
文件中注释了该行,从命令行运行了gradlew clean
,重新启动了Android Studio,然后在Universe中恢复了订单。
