多个dex文件定义Lcom/amazonaws/AmazonWebServiceClient；

Question

我正在尝试在我的 Android 应用程序中使用 Amazon AWS SDK。该应用程序已使用 C2Call SDK。该应用程序正在运行，但只要我添加 AWS gradle 库，它就会开始给我多个 Dex 文件异常。我搜索了它并了解到它与多次定义的单个库有关，但是我不确定它是哪个，从日志中。我尝试删除不同的 gradle 编译选项，每当我添加一个 AWS 库时，它都会给出多重 Dex 异常。

这是我应用程序的 gradle 文件 -

apply plugin: 'com.android.application'

android {
    compileSdkVersion 22
    buildToolsVersion "21.1.2"

    defaultConfig {
        applicationId "com.test.test"
        minSdkVersion 14
        targetSdkVersion 22
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}
repositories {
    flatDir {
        dirs 'libs'
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    /*compile 'com.android.support:appcompat-v7:22.2.0'*/
    compile(name: 'lib-c2callsdk', ext: 'aar')
    compile 'com.amazonaws:aws-android-sdk-cognito:2.2.3'
    compile 'com.amazonaws:aws-android-sdk-ses:2.2.3'
    compile 'com.amazonaws:aws-android-sdk-ddb:2.2.3'
}

我也尝试添加和删除 appcompact。

这是我收到的错误日志 -

如果我 select 只是 AWS 库之一，例如 cognito，它会给出相同的异常而没有那些长警告。

知道我在这里做错了什么吗？我怎样才能找到确切的问题？

更新：

我尝试将以下内容放入应用程序的 gradle -

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    /*compile 'com.android.support:appcompat-v7:22.2.0'*/
    compile(name: 'lib-c2callsdk', ext: 'aar'){
        exclude group:'gson'
        exclude group:'commons-logging'
    }
    compile ('com.amazonaws:aws-android-sdk-core:2.+'){
        exclude group:'gson'
        exclude group:'commons-logging'
    }
    /*compile 'com.amazonaws:aws-android-sdk-cognito:2.+'
    compile 'com.amazonaws:aws-android-sdk-ses:2.+'
    compile 'com.amazonaws:aws-android-sdk-ddb:2.+'*/
    /*compile 'com.google.code.gson:gson:2.3'*/
}

现在错误减少到这个 -

Answer 1

错误提示 com.amazonaws.AmazonWebServiceClient 被定义了多次。您的项目中可能引用了多个 AWS Android SDK 副本，其中一个显然来自 Maven。请您仔细检查一下 libs 文件夹下是否有其他文件？我不熟悉c2call。不确定其中是否有与 AWS SDK 冲突的内容。一种检查方法是解压缩 jar 并搜索特定的 class。这是一个例子：

unzip -l *.jar | grep AmazonWebServiceClient

至于警告，请忽略它。 AWS Android SDK 依赖于使用 JDK 1.5 编译的 apache-commons-logging 1.1.1。 Android 不喜欢但可以忍受。

Answer 2

这是我解决问题的方法（以帮助那些将来可能需要这些步骤的人）-

将 AAR 文件扩展名更改为 zip 并解压。
打开解压文件夹找到classes.jar
下载JarJar.jar

创建一个规则文件，您可以在其中提及需要重构的包或 class。这是我的规则文件 -

rule com.amazonaws.services.s3.a.* com.jarjar.@0
rule com.amazonaws.services.s3.model.a.* com.jarjar.@0
rule com.amazonaws.services.s3.model.* com.jarjar.@0
rule com.amazonaws.services.s3.* com.jarjar.@0
rule com.amazonaws.sdk.* com.jarjar.@0
rule com.amazonaws.regions.* com.jarjar.@0
rule com.amazonaws.javax.xml.stream.xerces.impl.msg.* com.jarjar.@0
rule com.amazonaws.http.* com.jarjar.@0
rule com.amazonaws.e.* com.jarjar.@0
rule com.amazonaws.d.* com.jarjar.@0
rule com.amazonaws.c.* com.jarjar.@0
rule com.amazonaws.b.* com.jarjar.@0
rule com.amazonaws.a.* com.jarjar.@0
rule com.amazonaws.auth.* com.jarjar.@0
rule com.amazonaws.* com.jarjar.@0
rule com.amazon.device.messaging.development.* com.jarjar.@0
rule com.amazon.device.messaging.* com.jarjar.@0
rule com.amazon.* com.jarjar.@0
rule com.google.gson.stream.* com.jarjar.@0
rule com.google.gson.reflect.* com.jarjar.@0
rule com.google.gson.internal.bind.* com.jarjar.@0
rule com.google.gson.internal.* com.jarjar.@0
rule com.google.gson.annotations.* com.jarjar.@0
rule com.google.gson.* com.jarjar.@0

运行 jarjar.jar。这是一个示例命令 -

java -jar "D:\Android\Dev Tools\jarjar-1.4.jar" process jarjarrules.txt lib-c2callsdk\classes.jar classes.jar

复制结果 classes.jar 并将副本转换为 zip。提取它以验证重构。
现在复制结果 classes.jar 并在提取的库文件夹中用它替换旧的 classes.jar。
将文件夹压缩成zip（记得在根目录上有classes.jar。
将 zip 重命名为 aar 扩展名。
在您的项目中使用新的 aar 库。

PS: 当然可以，感谢扬帆提供解决方案

Answer 3

我正在使用 AWS rekognition 库进行图像识别

我在使用

时遇到了同样的问题

implementation 'com.amazonaws:aws-java-sdk-rekognition:1.11.66
implementation 'com.amazonaws:aws-android-sdk-core:2.4.4

在android studio中，我已经通过替换依赖解决了 implementation 'com.amazonaws:aws-android-sdk-core:2.4.4 来自 jar file .

dependencies {
implementation 'com.android.support:appcompat-v7:26.1.0'
implementation 'com.android.support.constraint:constraint-layout:1.0.2'

implementation 'com.amazonaws:aws-android-sdk-core:2.2.+'
implementation files('yourJarFileLocation/AmazonRekognition/lib/aws-android-sdk-rekognition-2.6.9.jar')

}

接下来只需清理、重建，运行。有效

多个dex文件定义Lcom/amazonaws/AmazonWebServiceClient；

Multiple dex files define Lcom/amazonaws/AmazonWebServiceClient;
