Gradle项目 - 可以构建但不能运行它

Question

我的Android项目包含3个build.gradle个文件：

项目build.gradle：

// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
    repositories {
//        mavenLocal()
        jcenter()
    }
    dependencies {
//        classpath 'com.android.tools.build:gradle:1.1.0'
        classpath 'com.android.tools.build:gradle:1.1.3'
    }
}

allprojects {
    repositories {
        jcenter()
    }
}

MYAPP build.gradle

apply plugin: 'com.android.library'
android {
    dexOptions {
        preDexLibraries = false
    }

    compileSdkVersion 17
    buildToolsVersion "21.1.1"

    defaultConfig {
        minSdkVersion 8
        targetSdkVersion 17
    }

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
        }
    }
}

dependencies {
    compile 'com.android.support:support-v4:18.0.0'
    compile files('libs/CWAC-AdapterWrapper.jar')
}

和Facebook SDK：

apply plugin: 'com.android.library'

android {
    dexOptions {
        preDexLibraries = false
    }
    compileSdkVersion 8
    buildToolsVersion "21.1.1"

    defaultConfig {
        minSdkVersion 8
        targetSdkVersion 8
    }

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
        }
    } }

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

我能够构建项目但不能运行它。例外是：

有些东西是重复但我不知道是什么。你有什么想法没有运行吗？

问题似乎是前两个模块在我的DEX中包含TWICE

  

settings.gradle include'：androidImageCachemaster'include   '：facebookSDK'

然后

  

¸¸dependencies{       编译项目（'：facebookSDK'）       编译项目（'：androidImageCachemaster'）

这是屏幕截图

Answer 1

文件中是否有一个名为DiskCache的函数： com.android.dx.command.Main.main

这似乎与facebook sdk中的功能相冲突。尝试重命名您的功能

已更新-------

请在build.grade中尝试此操作。这应该编译依赖项，但将其从最终构建中排除：

android {
    compileSdkVersion x
    buildToolsVersion "x"

    packagingOptions {
        exclude 'support-v4'
    }
    ...
}

Answer 2

热门build.gradle：

// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
    repositories {
        jcenter()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:1.1.3'
    }
}

allprojects {
    repositories {
        jcenter()
    }
}

Facebook for Android：

1. 在此处下载Facebook for Android Gradle库：https://developers.facebook.com/docs/android。

2. 将其作为模块导入您自己的项目。

3. 它会将其添加为模块。因此，请添加到您自己的build.gradle，compile project(':facebook-android-sdk-4.0.1')作为依赖项。

app/build.gradle

apply plugin: 'com.android.application' // changed to application
