java - 任务 ':app:transformClassesWithJarMergingForDebug 执行失败

Question

我创建了一个 Android 应用程序并且运行在 API 级别 21 以上。但不能在 API 级别 21 以下运行。

这是错误日志:

错误:任务 ':app:transformClassesWithJarMergingForDebug' 执行失败。 com.android.build.api.transform.TransformException:java.util.zip.ZipException:重复条目:android/support/v4/accessibilityservice/AccessibilityServiceInfoCompat$AccessibilityServiceInfoVersionImpl.class帮助我度过难关

下面是我的gradle代码:

apply plugin: 'com.android.application'
android {
    compileSdkVersion 23
    buildToolsVersion "23.0.3"

    defaultConfig {
        applicationId "*******"
        minSdkVersion 16
        targetSdkVersion 23
        multiDexEnabled true
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            useProguard true
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
    dexOptions {
        javaMaxHeapSize "4g"
        preDexLibraries = false
    }
    packagingOptions {
        exclude 'META-INF/NOTICE.txt' // will not include NOTICE file
        exclude 'META-INF/LICENSE.txt' // will not include LICENSE file
    }
}

dependencies {
    compile fileTree(exclude: 'android-support-*.jar', dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    compile project(':simple-crop-image-lib')
    //    compile 'com.github.navasmdc:MaterialDesign:+'
    compile project(':material-login')
    compile 'com.android.support:multidex:1.0.1'
    compile ('com.android.support:appcompat-v7:23.4.0'){
        exclude module: 'support-v4'
    }
}

Answer 1

首先编译构建

compile 'com.android.support:multidex:1.0.1'

在你的 AndroidManifest.xml 添加这行 android:name

<application
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:supportsRtl="true"
    android:theme="@style/AppTheme"
    android:name="android.support.multidex.MultiDexApplication"
    >

并且在你的build.gradle中添加

dexOptions {
    //incremental = true;
    preDexLibraries = false
    javaMaxHeapSize "4g"
}


packagingOptions {
     exclude 'META-INF/NOTICE.txt' // will not include NOTICE file
    exclude 'META-INF/LICENSE.txt' // will not include LICENSE file
}
