我们正在尝试在 travis CI 上运行测试。我们有一个使用 android.support.v4.widget.DrawerLayout 的类。

当我们使用android支持v4库时
build.gradle->

targetSdkVersion: 19
`compile 'com.android.support:support-v4:20.0.0'`

.travis.yml

- build-tools-19.1.0
- android-19
- extra-android-support
- extra-google-google_play_services
- extra-google-m2repository

我们没有得到这个错误但是在使用

build.gradle ->

targetSdkVersion: 21
com.android.support:support-v4:21.0.+

.travis.yml

- build-tools-21.0.1
- android-21
- extra-android-support
- extra-google-google_play_services
- extra-google-m2repository

我们得到错误

Travis甚至显示已经下载并安装了Android Support Library revision 21，但是还是出现上面的错误。

更新:

我们尝试在 travis 人员设置的 VM 上运行测试。

• 最初在机器上运行时，测试失败并出现相同的错误。
• 尝试将 support-v4 aar 文件中的 internal_impl-21.0.0.jar 手动复制到我们的 libs/ 目录和测试通过。
• 在虚拟机上手动安装 Android SDK 工具 23.0.5 并通过测试。

我们的项目.travis.yml有以下几行:

- 工具 - 平台工具 - 构建工具 21.1.1 - android-21 - 额外的安卓支持 - 额外的 android-m2 存储库 - extra-google-m2repository travis 上的测试仍然失败。

最佳答案

这听起来像是 travis 中的错误。如果它不使用 Gradle 来构建所有内容，而是自己构建一些内容(这听起来像是，因为您有特殊的 YAML 文件列出依赖项)，它需要处理 AAR 文件依赖项，不仅包括 classes.jar，还包括 jars也在 libs/下。

关于android - 在 travis support-v4 21.0 上找不到 android.support.v4.widget.DrawerLayoutImpl 的类文件，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/26488015/
