我有许多Espresso仪器测试。它们在Android 5.0上运行良好。
这是我的build.gradle:
buildscript {

classpath 'io.fabric.tools:gradle:1.+'
}

}

variant.setIgnore(true);
}
}

}
但如果我尝试在Android 4.3上启动Espresso测试,我会收到错误:
java.lang.NoClassDefFoundError: com/mycompany/activity/MainActivity$1
Caused by: java.lang.IllegalAccessError: Class ref in pre-verified class resolved to unexpected implementation

您可以尝试修改gradle文件的这一部分
androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2') {
exclude group: 'com.android.support', module: 'support-annotations'
exclude group: 'com.google.guava', module: 'guava'
exclude group: 'junit', module: 'junit'
}
并添加:
androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2') {
exclude group: 'com.android.support', module: 'support-annotations'
exclude group: 'com.google.guava', module: 'guava'
exclude group: 'junit', module: 'junit'
exclude group: 'com.android.support', module: 'appcompat'
exclude group: 'com.android.support', module: 'support-v4'
}

这是Google报道的已知错误: https://issuetracker.google.com/issues/37324038
总而言之,如果你的测试apk不适合单个文件,那么在API< 21上不完全支持multidex,这最终会包含在Android工具中,multidex 1.0.2已经有了这个支持但是正如谷歌开发者所说:
确实,1.0.2包含所有必要的支持,但缺少插件中的支持。我将尝试在接下来的几个预览版本中发布插件更改,但是当它发生时我无法提供任何硬性保证。
这仍然不是当前版本:android gradle 3.0.0 alpha8插件。
只是为了确保这与此问题无关: Android Espresso multidex fail
定义一个multidex keep proguard文件并在那里放入在.apk的主dex文件中找不到的每个类
debug {
applicationIdSuffix '.debug'
multiDexKeepProguard file('../proguardRules/multidex-proguard.pro')
}
你的multidex proguard文件应该包含在主dex文件中找不到的类,在我的例子中它是RxJavaPlugin,所以我的multidexproguard文件包含:
-keep class com.mycompany.activity.MainActivity.** { *; }
