java - 多个 Dex 文件定义 Landroid/support/v4

Question

几个小时以来，我一直在努力解决这个问题。我尝试导入 2bard 的 AndroidPianoView作为一个库项目(PianoView 和 PianoViewExample 都在里面)，它们都有一个 support-v4 jar在他们的libs目录。

我的项目在 Android Studio 中。

从一个或两个目录中删除 jar 对我没有好处，我尝试按照 this popular question 中的解决方案进行操作没有成功。

这是运行 gradle -q:app:dependencies 的依赖关系树:

compile - Classpath for compiling the main sources.
+--- com.android.support:appcompat-v7:22.2.1
|    \--- com.android.support:support-v4:22.2.1
|         \--- com.android.support:support-annotations:22.2.1
\--- project :PianoViewExample
     \--- project :PianoView

以下是 build.gradle 文件:

我的项目

buildscript {
    repositories {
        mavenCentral() // or jcenter()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:1.3.1'
    }
}

apply plugin: 'com.android.application'

android {
    compileSdkVersion 22
    buildToolsVersion "22.0.1"

    defaultConfig {
        applicationId "com.ajbowler.jamory"
        minSdkVersion 15
        targetSdkVersion 22
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    compile 'com.android.support:appcompat-v7:22.2.1'
    compile project(':PianoViewExample')
}

        // Move the build types to build-types/<type>

        debug.setRoot('build-types/debug')

    }
}

当我 exclude module: 'support-v4' 时会发生什么在主项目中

buildscript {
    repositories {
        mavenCentral() // or jcenter()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:1.3.1'
    }
}

apply plugin: 'com.android.application'

android {
    compileSdkVersion 22
    buildToolsVersion "22.0.1"

    defaultConfig {
        applicationId "com.ajbowler.jamory"
        minSdkVersion 15
        targetSdkVersion 22
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile project(':PianoViewExample')
    compile('com.android.support:appcompat-v7:23.0.1') {
        configurations {
            all*.exclude group: 'com.android.support', module: 'support-v4'
            all*.exclude group: 'com.google.android.gms', module: 'play-services'
        }
    }
}

我真的很感激这方面的一些帮助。我一直无法弄清楚问题来自过去 exclude - 从 PianoView 模块之一中获取支持 jar，但该模块不起作用。

Answer 1

是的，今天刚刚修好了。就我而言，这是 Maven 中支持 v4 和支持 v7 之间的冲突。我所做的只是在主项目的支持 v7 标记中添加支持 v4 的排除标志。
我不得不从 v7 中排除 v4，因为我已经在使用它(v4 的导入位于我的 pom 文件的上方 5 行)。
