Question

我正在尝试在我的Android应用程序中对特定模块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，但我不认为这在我的情况下是有意义的。我的应用程序中没有64k方法引用，也没有依赖于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目录中运行检测测试，因为需要目标应用程序的Context。

有没有人知道为什么我会收到这个错误？

Answer 1

导致是因为当您进行测试时需要使用其他依赖项，例如JUnit，Mockito等。仅在运行测试时使用这些依赖项，并且在项目方法中添加方法计数计数。

在您的gradle中添加此

default config {
  ....
  multiDexEnabled true
}

如果minSdkVersion＆lt; 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);
        ....
    }
}

在你的清单中你需要声明它

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

测试时64k限制 - Android
