android - 测试时的 64k 限制 - Android

Question

我正在尝试在我的 android 应用程序中的特定模块上运行一些测试，但由于某种原因，我不断收到这些构建错误消息:

Error:The number of method references in a .dex file cannot exceed 64K.

我读到了 android 中的 64k 限制，但我认为这对我来说没有意义。我的应用程序中没有 64k 方法引用，也没有依赖于具有 64k 方法引用的库(我认为)。

这是我的模块级 build.gradle:

    apply plugin: 'com.android.library'

    android {
        compileSdkVersion 25
        buildToolsVersion "25.0.2"

        defaultConfig {
            minSdkVersion 19
            targetSdkVersion 25
            versionCode 1
            versionName "1.0"

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

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

    dependencies {
        compile fileTree(include: ['*.jar'], dir: 'libs')
        androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
            exclude group: 'com.android.support', module: 'support-annotations'
        })
        compile 'com.android.support:appcompat-v7:25.1.0'
        compile 'com.tom_roush:pdfbox-android:1.8.9.1'
        compile 'org.parceler:parceler:1.1.8'
        testCompile 'junit:junit:4.12'
        testCompile 'org.mockito:mockito-core:2.8.9'
    }

项目级 build.gradle 文件:

// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {

    repositories {
        maven { url "http://dl.bintray.com/shivasurya/materialsteppers" }
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.3.3'
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        maven { url "http://dl.bintray.com/populov/maven" }
        maven { url "https://jitpack.io" }
        jcenter()
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

我正在尝试在 androidTest 中运行仪器测试目录，由于需要 Context的目标应用程序。

有人知道为什么我会收到此错误吗？

Answer 1

是因为runt测试需要用到其他依赖，比如JUnit , Mockito等。这些仅在您运行测试时使用，并且方法计数与您的项目方法计数一起添加。

在你的毕业典礼上添加这个

default config {
  ....
  multiDexEnabled true
}

如果 minSdkVersion < 20 你需要支持

dependencies {
   ....
   compile 'com.android.support:multidex:1.0.1'
}

创建应用程序类

public class MyApplication extends Application {
    @Override
    protected void attachBaseContext(Context base) {
        super.attachBaseContext(base);
        MultiDex.install(this);
        ....
    }
}

在您的 list 中，您需要声明它

<application
    android:name=".MyApplication" >
    ...
</application>
