android - java.util.zip.ZipException : duplicate entry: org/apache/commons/codec/binary/Base64. 类

Question

我遇到了这个错误。

Error:Execution failed for task ':app:packageAllDebugClassesForMultiDex'. java.util.zip.ZipException: duplicate entry: org/apache/commons/codec/binary/Base64.class

这是我的依赖项。我正在使用 OkHttp 进行网络操作。它在 5.0 及更高版本中完美运行。但在此之下它给出了这个错误。

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.google.code.gson:gson:2.3.1'
    compile files('libs/asmack-android-18-0.8.9.jar')
    compile files('libs/bugsense-3.6.1.jar')
    compile files('libs/commons-codec-1.4.jar')
    compile files('libs/eventbus-2.1.0-beta-1.jar')
    compile files('libs/glide-3.6.1.jar')
    compile 'com.facebook.android:facebook-android-sdk:4.+'
    compile 'com.google.android.gms:play-services:8.4.0'
    compile 'com.rockerhieu.emojicon:library:1.0'
    compile 'com.navercorp.pulltorefresh:library:3.2.0@aar'
    compile files('libs/okhttp-1.2.1-jar-with-dependencies.jar')
    compile files('libs/okio-1.0.1.jar')
    compile files('libs/universal-image-loader-1.9.3-SNAPSHOT.jar')
    compile files('libs/volley.jar')
    compile 'com.android.support:appcompat-v7:23.1.0'
    compile files('libs/org.apache.http.legacy.jar')
    }

整个网格如下。

apply plugin: 'com.android.application'

 android {
    compileSdkVersion 23
    buildToolsVersion "22.0.1"

    packagingOptions {
        exclude 'META-INF/license.txt'
        exclude 'META-INF/LICENSE.txt'
        exclude 'META-INF/notice.txt'
        exclude 'META-INF/NOTICE.txt'
    }

    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_7
        targetCompatibility JavaVersion.VERSION_1_7
    }

    defaultConfig {
        applicationId "com.onesnaps"
        minSdkVersion 15
        targetSdkVersion 23
        multiDexEnabled true
    }

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

gradle sync 没有报错。在运行时，它会为 Lollipop 下方的设备抛出此错误。

duplicate entry: org/apache/commons/codec/binary/Base64.class

...

It works perfect in 5.0 and above

听起来您可能遇到了这个问题:

https://developer.android.com/about/versions/pie/android-9.0-changes-28#apache-p

Note: The android:required="false" attribute is required for apps that have a minimum SDK of 23 or lower, because on devices with API levels lower than 24, the org.apache.http.legacy library is not available. (On those devices, the Apache HTTP classes are available on the bootclasspath.)

因此，你不需要依赖

     compile files('libs/org.apache.http.legacy.jar')

当您为较低版本的 Android 编译时。

或

app:packageAllDebugClassesForMultiDex

您可能超出了方法计数限制，需要启用 multidex
