Gradle 项目 - 可以构建但不能运行

Question

我的 Android 项目包含 3 个build.gradle 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()
    }
}

MYAPPbuild.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：

有些东西是重复的，但我不知道是什么。你知道它为什么不运行吗？

问题似乎是我的 DEX 中包含 TWICE 的前 2 个模块

settings.gradle 包括 ':androidImageCachemaster' 包括 ':facebookSDK'

然后

¸¸依赖项{ 编译项目（'：facebookSDK'） 编译项目(':androidImageCachemaster')

这是屏幕截图

Answer 1

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

这似乎与 facebook sdk 中的功能冲突。尝试重命名您的功能

更新-------

在您的 build.grade 中尝试这个。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

顶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()
    }
}

Android 版 Facebook：

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. 它会将其添加为一个模块。所以添加到你自己的build.gradle、compile project(':facebook-android-sdk-4.0.1') 作为依赖项。

app/build.gradle:

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

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

android {
    compileSdkVersion 22 // <-- updated
    buildToolsVersion "22.0.1" // <-- updated

    defaultConfig {
        minSdkVersion 11 // <-- updated
        targetSdkVersion 22 // <-- updated
    }

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

dependencies {
    compile 'com.android.support:support-v4:22.0.0' // <-- updated
    compile files('libs/CWAC-AdapterWrapper.jar')
    // compile project(':facebook-android-sdk-4.0.1') // <-- something like this
}

Answer 3

问题的答案是这样的： 我的项目两次包含这两个模块：
'androidImageCachemaster'
'facebookSDK'

在我从项目中删除引用后，一切运行顺利。
