MultiDexApplication的使用会导致Robolectric测试应用程序类，打破

问题描述

添加多DEX支持，支持V4-R21采用摇篮DEF（https://plus.google.com/+IanLake/posts/JW9x4pcB1rj)

 应用插件：com.android.application

安卓{
compileSdkVersion 19
buildToolsVersion20.0.0

defaultConfig {
    的applicationIDinfo.osom.multidex
    的minSdkVersion 19
    targetSdkVersion 19
    版本code 1
    VERSIONNAME1.0
}
buildTypes {
    推出 {
        runProguard假
        proguardFiles getDefaultProguardFile（'ProGuard的-android.txt'），'proguard-rules.pro
    }
}

dexOptions {
    preDexLibraries = FALSE
}

afterEvaluate {
    tasks.matching {
    it.name.startsWith（DEX）
    } {。每个DX  - ＆GT;
    如果（dx.additionalParameters == NULL）{
        dx.additionalParameters = []
    }
    dx.additionalParameters + ='--multi-DEX
    dx.additionalParameters + = - 主-DEX-列表= $ PROJECTDIR / multidex.keep的ToString（）
}
 

现在这个工程的应用程序本身，我能够构建和部署，但是当我运行一个robolectric测试我的应用程序类，我从ZipUtils失败（这是陷入MultiDex.java）。其他的测试运行良好。下面是跟踪 -

解决方案

这是一个已知的错误，等待修复：的

Adding Multi dex support with the support v4-r21 using gradle def (https://plus.google.com/+IanLake/posts/JW9x4pcB1rj)

apply plugin: 'com.android.application'

android {
compileSdkVersion 19
buildToolsVersion "20.0.0"

defaultConfig {
    applicationId "info.osom.multidex"
    minSdkVersion 19
    targetSdkVersion 19
    versionCode 1
    versionName "1.0"
}
buildTypes {
    release {
        runProguard false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}

dexOptions {
    preDexLibraries = false
}

afterEvaluate {
    tasks.matching {
    it.name.startsWith('dex')
    }.each { dx ->
    if (dx.additionalParameters == null) {
        dx.additionalParameters = []
    }
    dx.additionalParameters += '--multi-dex'
    dx.additionalParameters += "--main-dex-list=$projectDir/multidex.keep".toString()
}

Now this works for the app itself and I'm able to build and deploy but when I run a robolectric test for my Application class, I get a failure from ZipUtils (which is caught in MultiDex.java). The other tests are running fine. Here is the trace -
