Android Espresso Framework Resolved versions for app (25.3.1) and test app (23.1.1) 错误

Question

当我尝试通过 gradle 添加 espresso 库时收到此错误消息。我该如何解决？

Answer 1

问题是 espresso 使用的支持库版本比你的要旧。由于您的项目中已经有 then，因此请将它们从 espresso 中排除。因此，在您的 build.gradle 文件中，您应该替换：

androidTestCompile 'com.android.support.test.espresso:espresso-core:2.2.2'

与：

androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
    exclude group: 'com.android.support', module: 'support-annotations'
})

如果您有更多冲突，请尝试排除更多支持模块（如 appcompat、设计等）。

Answer 2

使用此代码测试像 recyclerview 这样的操作

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })
androidTestCompile('com.android.support.test.espresso:espresso-contrib:2.2', {

    exclude group: 'com.android.support', module: 'appcompact'
    exclude group: 'com.android.support', module: 'support-v4'
    exclude group: 'com.android.support', module: 'support-annotations'
    exclude module: 'recyclerview-v7'
})

否则使用

compile fileTree(dir: 'libs', include: ['*.jar'])
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
exclude group: 'com.android.support', module: 'appcompact'
        exclude group: 'com.android.support', module: 'support-v4'
        exclude group: 'com.android.support', module: 'support-annotations'
exclude module: 'recyclerview-v7'
    })
