多个dex文件定义Lcom/amazonaws/AmazonWebServiceClient；

Question

我正试图在我的Android应用程序中使用Amazon。这个应用程序已经使用了C2Call SDK。该应用程序正在工作，但一旦我添加AWS级库，它就开始给我多个Dex文件异常。我搜索了它，并知道它与多次定义的单个库相关，但是我不确定日志中的是哪一个库。我尝试删除不同的gradle编译选项，每当我添加AWS库时，它就会给出多个Dex异常。

这是我的应用程序的分级文件-

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'
}

我也试着添加和删除appcompact。

这是我得到的错误日志-

如果我只选择一个AWS库，比如定位，它就会在没有长警告的情况下提供相同的异常。

你知不知道我在这里做错了什么，怎么才能找到确切的问题？

更新：

我试过把下面的内容放进应用程序的等级-

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-

Answer 1

错误说com.amazonaws.AmazonWebServiceClient是多次定义的。很可能在您的项目中引用了几个Android副本，其中一个显然来自Maven。请你再检查一遍，在libs文件夹下没有另一个？我不熟悉c2call。不确定其中是否存在与AWS冲突的内容。检查的一种方法是解压缩jars并搜索特定的类。下面是一个示例：

unzip -l *.jar | grep AmazonWebServiceClient

至于警告，你可以无视它。Android依赖1.1.1，它是用JDK1.5编译的。Android不喜欢它，但可以接受它。

Answer 2

我做了些什么来解决这个问题(帮助那些将来可能需要的人)-

1. 将AAR文件扩展名更改为zip并解压缩它。
2. 打开解压缩文件夹以查找classes.jar
3. 下载JarJar.jar
4. 创建一个规则文件，您可以在其中提到需要重构的包或类。这是我的规则文件- 规则com.amazonaws.services.s3.a.* com.jarjar.@0规则com.amazonaws.services.s3.model.a.* com.jarjar.@0规则com.amazonaws.services.s3.model.* com.jarjar.@0规则com.amazonaws.services.s3.s3.* com.jarjar.@0规则com.amazonaws.sdk.* com.jarjar.@0规则com.amazonaws.regions.* com.jarjar.@规则com.amazonaws.services.s3.model.*com.jarjar@0规则com.amazonaws.javax.xml.stream.xerces.impl.msg.* com@0规则com.amazonaws.d*com.jarjar@0规则com.amazonaws.c*com.jarjar@com.jarjar@0规则com.amazonaws.a*com.jarjar@0规则com.amazonaws.auth*com.amazonaws.auth。@0规则com.amazonaws.auth。@0规则com.amazonaws.c*com.amazonaws.b*com.jarjar。@ com.amazon.device规则.messaging.development.* com.jarjar.@0规则com.amazon.device.Message.* com.jarjar.@0规则com.amazon.* com.jarjar.@0规则com.google.gson.stream.* com.jarjar.@0规则com.google.gson.refl.* com.jarjar.@0规则com.google.gson.bind.* com.jarjar.@0规则com.google.gson.inside.* com.jarjar.@0规则com.google.gson.com.jarjar.* com.jarjar.@0规则com.google.gson*com.jarjar@0
5. 运行jarjar.jar。这是一个示例命令- java -jar“D：\Android\jarjar-1.4.jar”进程jarjarrules.txt lib-c2callsdk\classes.jar classes.jar
6. 复制生成的classes.jar并将副本转换为zip。提取它以验证重构。
7. 现在，复制生成的classes.jar，并在解压缩的库文件夹中替换旧的classes.jar。
8. 将文件夹压缩为zip(请记住根目录上有classes.jar )。
9. 将zip重命名为aar扩展。
10. 在项目中使用新的aar库。

当然，感谢杨帆提出的解决方案。

Answer 3

我正在使用AWS推理库进行图像识别。

我在使用

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

在android中，我通过用jar文件替换依赖项jar文件来解决问题。

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')

}

接下来就是打扫，重建，跑。啊，真灵
