Question

Gradle 3.3，WireMock 2.6.0。我通过Gradle构建我的Android项目。我用Espresso，Mockito编写单元测试，一切正常。

这是我的build.gradle：

dependencies {
    // for folder "androidTest"
    androidTestCompile 'com.android.support.test.espresso:espresso-core:2.2.2'
    androidTestCompile "org.mockito:mockito-android:2.7.21"
    androidTestCompile "org.powermock:powermock-api-mockito:1.6.6"
    androidTestCompile 'org.powermock:powermock-module-junit4:1.6.6'

    // for folder "test"
    testCompile 'junit:junit:4.12'
    testCompile 'org.powermock:powermock-api-mockito:1.6.6'
    testCompile 'org.powermock:powermock-module-junit4:1.6.6'
    }

我的项目是成功构建和单元测试成功运行。好。现在我想添加WireMock单元测试。所以我改变了我的build.gradle（如显示此博客：http://handstandsam.com/2016/01/30/running-wiremock-on-android/）：

    dependencies {
// for folder "androidTest"
androidTestCompile 'com.android.support.test.espresso:espresso-core:2.2.2'
androidTestCompile "org.mockito:mockito-android:2.7.21"
androidTestCompile "org.powermock:powermock-api-mockito:1.6.6"
androidTestCompile 'org.powermock:powermock-module-junit4:1.6.6'

//WireMock
androidTestCompile("com.github.tomakehurst:wiremock:2.6.0") {
    //Using Android Version Instead
    exclude group: 'org.apache.httpcomponents', module: 'httpclient'

    //Version conflict with our app's slf4j version
    exclude group: 'org.slf4j', module: 'slf4j-api'

    //Was getting a classpath conflict for org.objectweb.asm.AnnotationVisitor which is a part of 'net.minidev:asm'
    exclude group: 'org.ow2.asm', module: 'asm'

    //Was getting this warning, so decided to ignore this version included by WireMock.
    //Warning:Dependency org.json:json:20090211 is ignored as it may be conflicting with the internal version provided by Android.
    //In case of problem, please repackage with jarjar to change the class packages
    exclude group: 'org.json', module: 'json'
}

// for folder "test"
testCompile 'junit:junit:4.12'
testCompile 'org.powermock:powermock-api-mockito:1.6.6'
testCompile 'org.powermock:powermock-module-junit4:1.6.6'
}

当我运行我的应用程序时，一切正常。但是当我尝试为Android启动我的仪器化单元测试时，我得到了下一个错误：

    :app:compileDevAndroidTestShaders
:app:generateDevAndroidTestAssets
:app:mergeDevAndroidTestAssets
:app:transformClassesWithDexForDevAndroidTest FAILED

FAILURE: Build failed with an exception.

What went wrong:
Execution failed for task ':app:transformClassesWithDexForDevAndroidTest'.
com.android.build.api.transform.TransformException: com.android.ide.common.process.ProcessException: java.util.concurrent.ExecutionException: com.android.dex.DexIndexOverflowException: method ID not in [0, 0xffff]: 65536

当访问索引大于64K（Dex方法计数限制）的方法时，会发生DexIndexOverFlowException。这意味着android项目中实际的方法计数（引用）数量大于64K，应用程序的最终.dex文件将被拆分为多个dex文件。在这种情况下，您应该通过以下方式使您的应用程序支持multidex：

1-添加multidex依赖项：

    compile 'com.android.support:multidex:1.0.1'

2-将以下配置添加到app / build.gradle：

    android {

      defaultConfig {

          multidexEnabled true
       }
    }

3-创建自定义应用程序类以扩展MultiDexApplication

public MyApplication extends MultiDexApplication

4-在AndroidManifest.xml：

中，将此自定义类设置为应用程序的入口点

    <application
    android:name=".MyApplication"

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