升级长者preSSO到第2版没有我的单元测试将运行在pre-棒棒糖设备之后。请参阅下面的跟踪：

After upgrading Espresso to version 2 none of my unit tests will run on pre-lollipop devices. See the trace below:

15:07:07.627 [WARN] [org.gradle.api.Project] Tests on Samsung Galaxy S3 - 4.3 - API 18 - 720x1280 - 4.3 failed: Instrumentation run failed due to 'java.lang.IllegalAccessError'

堆栈跟踪同样是无益的。

The stack trace is equally unhelpful

有什么奇怪的是它在5.0的设备没有问题的工作。

What's strange is it work on 5.0 devices no problem.

推荐答案

旧设备在运行测试时，你有同样依赖于你的应用程序和测试应用程序的问题，仪器的应用程序。

Older devices have problems running tests when you have the same dependency in your app and test app that instruments the app.

要解决此问题，你必须弄清楚哪些依赖导致该问题。

To work around this issue, you will have to figure out which dependencies cause the problem.

在我的情况下，它是两个匕首和Es preSSO根据 javax.inject ，这是它如何可以固定：

In my case it was both Dagger and Espresso depending on javax.inject and this is how it can be "fixed":

androidTestCompile('com.android.support.test.espresso:espresso-core:2.0') {
    exclude group: 'javax.inject'
}

如果您有更多的或怪异的依赖，你可能有一个看的这个build.gradle 。

If you include more or weirder dependencies, you may have a look at this build.gradle.

在使用ES preSSO-的contrib，则可能需要这样做：

When using espresso-contrib, you may need to do this:

androidTestCompile('com.android.support.test.espresso:espresso-contrib:2.0') {
    exclude group: 'javax.inject'
    exclude group: 'com.android.support'
}
