I have a subclass of android.support.v7.widget.RecyclerView. It works fine when I use the application and testing.

However, when I include espresso-contrib in my gradle app file I get an exception when I try to run the same tests. The app still works. The same problem occurs in both sdk versions 21 and 22, on armv emulator and device. Using an x86 emulator it segfaults instead.

Gradle

androidTestCompile 'com.android.support.test.espresso:espresso-contrib:2.0'

Exception

    It seems like onFailedToRecycleView(Landroid/support/v7/widget/RecyclerView$ViewHolder;) is the difference. My guess is that espresso-contrib is trying to replace a class or Interface but does not implement all the methods? I still don't know how to fix it. Commented Mar 23, 2015 at 17:29

Espresso dependency is out of date. Reported and will be fixed in the future. https://code.google.com/p/android-test-kit/issues/detail?id=139

@JohnShelley I was able to get around the issue by excluding the Recyclerview module that the espresso-contrib library tries to use. androidTestCompile ('com.android.support.test.espresso:espresso-contrib:2.2'){ exclude module: 'support-annotations' exclude module: 'recyclerview-v7' }
Can't edit above comment anymore, I put the wrong line above. The correct line would be: androidTestCompile ('com.android.support.test.espresso:espresso-contrib:2.2'){ exclude module: 'support-annotations' exclude module: 'support-v4' exclude module: 'support-v13' exclude module: 'recyclerview-v7' }

please use Newest Gradle Plugin (is not a stable version)

Starting with 2.0.0 of the Android Gradle Plugin, Gradle build will fail if the main APK and the test APK use the same library (e.g. Guava) but in different versions.

To make the build succeed, just add a dependency for the newer version to the build.gradle

for example:

androidTestCompile "com.android.support:recyclerview-v7:${supportLibVersion}"

You can try to add that at the bottom of your gradle file (after every char)

/*
Resolves dependency versions across test and production APKs, specifically, transitive
dependencies. This is required since Espresso internally has a dependency on support-annotations.
*/
configurations.all {
    resolutionStrategy.force "com.android.support:support-annotations:$rootProject.supportLibraryVersion"
}

/*
All direct/transitive dependencies shared between your test and production APKs need to be
excluded from the test APK! This is necessary because both APKs will contain the same classes. Not
excluding these dependencies from your test configuration will result in an dex pre-verifier error
at runtime. More info in this tools bug: (https://code.google.com/p/android/issues/detail?id=192497)
*/
configurations.compile.dependencies.each { compileDependency ->
    println "Excluding compile dependency: ${compileDependency.getName()}"
    configurations.androidTestCompile.dependencies.each { androidTestCompileDependency ->
        configurations.androidTestCompile.exclude module: "${compileDependency.getName()}"
    }
}

It's from the Android-testing project on github

Maybe you forgot to add testInstrumentationRunner android.support.test.runner.AndroidJUnitRunner" in a defaultConfig{}
