android - 无法配置 travis 以在 android 项目上工作

Question

我发现了 Travis CI 的几个问题，我一直在解决它们，但最后一个我不能。

我遇到了常见错误 com.android.ddmlib.InstallException: 建立 session 失败

这是我的 travis 文件:

language: android

before_install:
 - chmod +x gradlew

android:
  components:
    # Uncomment the lines below if you want to
    # use the latest revision of Android SDK Tools
    # - platform-tools
    # - tools

    # The BuildTools version used by your project
    - tools
    - build-tools-23.0.3

    # Additional components
    - extra-google-m2repository
    - extra-android-m2repository

    # The SDK version used to compile your project
    - android-23

    # Specify at least one system image,
    # if you need to run emulator(s) during your tests
    - sys-img-armeabi-v7a-android-23
    #- sys-img-x86-android-17

env:
  global:
    # install timeout in minutes (2 minutes by default)
    - ADB_INSTALL_TIMEOUT=8

# Emulator Management: Create, Start and Wait
before_script:
  - echo no | android create avd --force --name test --target android-23 --abi armeabi-v7a
  - emulator -avd test -no-skin -no-audio -no-window -gpu off -no-boot-anim &
  - android-wait-for-emulator
  - adb devices
  - adb shell input keyevent 82 &

script:
  - echo $ADB_INSTALL_TIMEOUT
  - android list target
  - ./gradlew connectedAndroidTest

after_failure:
  # Customize this line, 'android' is the specific app module name of this project. Shows log.
  - export MY_MOD="SimpleLock"
  - export MY_LOG_DIR="$(pwd)/app/build/reports/androidTests/connected/"
  - pwd && cd "${MY_LOG_DIR:-.}" && pwd && ls -al
  - sudo apt-get install -qq lynx && lynx --dump index.html > myIndex.log
  - lynx --dump com.android.builder.testing.ConnectedDevice.html > myConnectedDevice.log
  - lynx --dump com.android.builder.testing.html > myTesting.log
  - for file in *.log; do echo "$file"; echo "====================="; cat "$file"; done || true

这是我的 travis 输出: https://travis-ci.org/GarceGon/SimpleLock/builds/139367600

解决方案:

删除 -no-boot-anim 选项以等待模拟器准备就绪并将超时增加到 10 分钟。

---

第一期:

替换

  - emulator -avd test -no-skin -no-audio -no-window -gpu off -no-boot-anim &

通过

  - emulator -avd test -no-skin -no-audio -no-window -gpu off &

删除 -no-boot-anim 选项，android-wait-for-emulator 脚本依赖于启动动画来检测模拟器何时准备就绪，正如我解释的 here 。

我 fork 了你的项目以在开发分支和 Travis-CI 构建 passed 上确认这一点，但是......

第二期:

后来我使用主分支和构建 failed 重新创建了更改 ...

Caused by: com.android.ddmlib.ShellCommandUnresponsiveException

Sean Barbeau 很好地解释了问题的 this 版本:

# install timeout in minutes (2 minutes by default)
- ADB_INSTALL_TIMEOUT=8

并且您还修复了另一个超时问题，解释为 here 和 here 需要更多时间，see:

Android Gradle Plugin had a hard coded timeout value that was too low.

Google fixed it (version 2.0.0-beta3):

https://code.google.com/p/android/issues/detail?id=189764

So what do we put in build.gradle to set this timeout value?

Currently it's all attached to android.adbOptions.timeOutInMs.

Sample: Google project Increasing ADB timeout and adding Travis-ci support. It works!

// This enables long timeouts required on slow environments, e.g. Travis
adbOptions {
    timeOutInMs 10 * 60 * 1000  // Set the timeout to 10 minutes
    installOptions "-d","-t"
}

我像 Mark McDonald 那样将超时从 1 分钟增加到 10 分钟，构建 passed :
