Android Studio：错误：任务＆＃39;：app：transformClassesWithJarMergingForRelease＆＃39;执行失败。 ＆GT;

Question

我需要帮助，我是Android Studio的新手，我得到了这个错误：

Error:Execution failed for task ':app:transformClassesWithJarMergingForRelease'.
com.android.build.api.transform.TransformException: java.util.zip.ZipException: duplicate entry: android/support/v4/database/DatabaseUtilsCompat.class

这是我的build.gradle文件，希望这可以提供帮助：

android {
    compileSdkVersion 25
    buildToolsVersion "25.0.2"

    defaultConfig {
        applicationId "com.app_name.vallic.hr"
        minSdkVersion 14
        targetSdkVersion 25
        multiDexEnabled true

        ndk {
            moduleName "player_shared"
        }
    }

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


    }

    configurations {
        all*.exclude group: 'com.android.support', module: 'support-v4'
        all*.exclude group: 'com.android.support', module: 'support-annotations'
    }

    sourceSets.main {
        jni.srcDirs = []// <-- disable automatic ndk-build call
    }
}

dependencies {
    compile('com.google.android.gms:play-services:+') {
        exclude module: 'support-v4'
        compile files('libs/dagger-1.2.2.jar')
        compile files('libs/javax.inject-1.jar')
        compile files('libs/nineoldandroids-2.4.0.jar')
        compile files('libs/support-v4-19.0.1.jar')
        compile('com.android.support:multidex:1.0.1')
    }
}

Answer 1

multidex也有support v4个库类，您已经单独包含了v4库。

因此，您必须从support v4库中排除multidex模块。

像这样更改mulitdex库初始化。

    compile ('com.android.support:multidex:1.0.1'){
            exclude module: 'support-v4'
        }

您的依赖关系初始化应该是这样的。

dependencies {
    compile('com.google.android.gms:play-services:+') {
        exclude module: 'support-v4'
    }
    compile files('libs/dagger-1.2.2.jar')
    compile files('libs/javax.inject-1.jar')
    compile files('libs/nineoldandroids-2.4.0.jar')
    compile files('libs/support-v4-19.0.1.jar')
    compile('com.android.support:multidex:1.0.1'){
    exclude module: 'support-v4'
    }
}
