Gradle项目-可以构建但无法运行

Question

My Android project consist of 3 build.gradle files:

Projects 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')
}

and 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' 
}

I am able to build the project but not to run it. The exception is:

Something is duplicated but I don't know what. Have you got any ideas why it does not run?

The problem seems to be that first 2 modules are included TWICE in my DEX

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

and then

¸¸dependencies { compile project(':facebookSDK') compile project(':androidImageCachemaster')

Here is the screen shot

Answer 1

Is there a function called DiskCache in the file: com.android.dx.command.Main.main

This seems to be conflicting with a function in the facebook sdk. Try to rename your funciton

UPDATED-------

Try this instead in your build.grade. This should compile the dependency but exclude it from the final build:

android {
    compileSdkVersion x
    buildToolsVersion "x"

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

Answer 2

Top 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. Download the Facebook for Android Gradle library here: https://developers.facebook.com/docs/android .

2. Import it as a module to your own project.

3. It will add it as a module. So add to your own build.gradle , compile project(':facebook-android-sdk-4.0.1') as a dependency.

app/build.gradle :

Download the Facebook for Android Gradle library here: 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

The answer to the problem was this: My project included these 2 modules twice:
'androidImageCachemaster'
'facebookSDK'

after I removed references from the project everything run smooth.
