处理AndroidStudio中的重复条目:java.util.zip.ZipException

Question

编辑:解决方案来自错误:java.util.zip.ZipException:重复条目在这里不起作用,因为我没有support-v4模块的问题

我正在尝试构建一个使用SpongyCastle的Android项目,但不幸的是它需要javax.naming来自jndi库的包.我添加了jndi甚至javaEE来使它工作,但gradle仍然有运行项目的问题(构建成功)

我的gradle.build文件:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.2"

    defaultConfig {
        applicationId "grylls.cryptotexting"
        minSdkVersion 15
        targetSdkVersion 23
        versionCode 1
        versionName "1.0"
        multiDexEnabled true
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:23.1.1'
    compile 'com.android.support:design:23.1.1'
    compile 'javax:javaee-api:7.0'
    compile files('lib/jndi-1.2.1.jar')
}

Gradle抛出此错误:

Error:Execution failed for task ':app:transformClassesWithJarMergingForDebug'.> 
com.android.build.api.transform.TransformException:java.util.zip.ZipException: 
duplicate entry:javax/mail/AuthenticationFailedException.class

当我试图排除javax.mail来自javax:javaee-api:7.0我:

Error:Execution failed for task ':app:transformClassesWithDexForDebug'.
> com.android.build.api.transform.TransformException: 
com.android.ide.common.process.ProcessException: 
org.gradle.process.internal.ExecException: 
Process 'command 'C:\Program Files\Java\jdk1.8.0_40\bin\java.exe'' finished with non-zero exit value 1

哪里可以找到javax.mail的重复,顺便说一下我甚至不需要？

为了正确包含 SpongyCastle，我必须更改依赖项：

dependencies {
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:23.1.1'
    compile 'com.android.support:design:23.1.1'
    compile 'com.madgag.spongycastle:core:1.51.0.0'
    compile 'com.madgag.spongycastle:prov:1.51.0.0'
    compile 'com.madgag.spongycastle:pkix:1.51.0.0'
    compile 'com.madgag.spongycastle:pg:1.51.0.0'
}

创建一个插入 BouncyCastle Provider 的类

import android.app.Application;
import java.security.Security;
public class Dynks extends Application {
    static { Security.insertProviderAt(new org.spongycastle.jce.provider.BouncyCastleProvider(), 1); }
}

并将其包含在“application”标签下的 AndroidManifest.xml 中：

...
    <application
            android:name="Dynks"
...
