将multidex添加到我的应用程序后，由于“ java.lang.NoClassDefFoundError”，检测运行失败 [英] Instrumentation run failed due to 'java.lang.NoClassDefFoundError' after adding multidex to my application

问题描述

这是此问题的延续：无法合并dex-如何排除适当的jar？

我没有典型的android项目，我只是在单独的模块上工作，该模块与活动无关清单中的，片段，UI等，我没有声明任何Android规范。这是我的清单：

I have not a typical android project, i am just working on the separate module, which is not connected with activies, fragments, UI etc. in my manifest i am not declaring any Android specifiacions. Here is my manifest:

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.moduleName.sampleName"
>
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION">
</uses-permission>

</manifest>

我有一个例外：

原因：com.android.dex.DexIndexOverflowException：方法ID不在[0，0xffff]中：65536

Caused by: com.android.dex.DexIndexOverflowException: method ID not in [0, 0xffff]: 65536

所以，这是我的build.gradle文件现在的样子：

So, here is what my build.gradle file looks like now:

apply plugin: 'com.android.library'
apply plugin: 'kotlin-android'
apply plugin: 'kotlin-kapt'

android {
compileSdkVersion 26
buildToolsVersion "26.0.2"


packagingOptions {
    exclude 'protobuf.meta'
}

testOptions {
    unitTests {
        includeAndroidResources = true
    }

}
sourceSets {
    test.java.srcDirs += ['build/generated/source/apt/test/debug']
}

defaultConfig {
    multiDexEnabled true
    minSdkVersion 15
    targetSdkVersion 26
    versionCode 1
    versionName "1.0"

    testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}

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

}

ext.daggerVersion = '2.11'
ext.roomVersion = '1.0.0-rc1'

dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])

implementation 'com.android.support:appcompat-v7:26.1.0'

implementation 'com.fasterxml.jackson.core:jackson-annotations:2.9.0'
implementation 'com.fasterxml.jackson.core:jackson-databind:2.9.1'

implementation 'com.android.support:multidex:1.0.2'

}

test包中的我的测试正常。

My tests that are in the package 'test' are working fine.

但是当我尝试在我的androidTest类包中运行一些测试时，我得到了：

But when i trying to run some test in my androidTest class package i get this:

开始运行测试
测试运行失败：由于'java.lang.NoClassDefFoundError'
空测试套件，使测试运行失败。

Started running tests Test running failed: Instrumentation run failed due to 'java.lang.NoClassDefFoundError' Empty test suite.

总结：

这个问题的开始在上面的链接中-添加杰克逊库后，我有大量方法，所以我添加了dex支持，这使我陷入了这个问题，我真的不知道该如何解决-试图排除一些依赖并只保留非常重要的内容，尝试清理项目，删除构建包。他们都没有工作。如果重要的是我在此模块中使用Kotlin

The beginning of this problem is in the link above - i was having large amount of methods after adding jackson library, so i added dex support and this got me to this problem, which i really don't know how to solve - trying to exclude some depenendencies and leave only really important, trying to clean the project, deleting build package. None of them worked. If it is important i am using Kotlin in this module

推荐答案

您可能必须在AndroidManifest中添加MultiDexApplication：

You may have to add MultiDexApplication in the AndroidManifest:

<?xml version="1.0" encoding="utf-8"?>
     <manifest xmlns:android="http://schemas.android.com/apk/res/android"
     package="com.example.myapp">
<application
     android:name="com.example.myapp.MyApplication" >
    ...
</application>

如果您覆盖应用程序类，将其更改为扩展MultiDexApplication（如果可能），如下所示：

If you do override the Application class, change it to extend MultiDexApplication (if possible) as follows:

public class MyApplication extends MultiDexApplication { ... }

在此处查看此Google官方博客以获取MultiDex支持
