我们正尝试在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，在build.gradle中:
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
build.gradle 时出现了问题。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
我们遇到了错误

即使Travis显示已下载并安装了Android Support Library修订版21，但仍出现上述错误。
更新：
我们尝试在travis提供的VM上运行测试。
- 当最初在机器上运行时，测试以相同的错误失败。
- 通过手动复制
support-v4aar文件中找到的internal_impl-21.0.0.jar到我们的libs/目录中进行尝试，测试通过了。 - 在VM上手动安装
Android SDK工具23.0.5后，测试通过。
我们的项目.travis.yml中有以下几行：
- 工具
- 平台工具
- 构建工具21.1.1
- Android-21
- extra-android-support
- extra-android-m2repository
- extra-google-m2repository
即使如此，测试仍在Travis上失败。
