Question

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

我遇到了常见的错误 com.android.ddmlib.InstallException: Failed to establish session

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选项以等待仿真器就绪并将超时时间增加到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脚本取决于启动动画，以便在我解释here时检测仿真器何时准备就绪。

我分叉你的项目以在开发分支和Travis-CI构建passed上确认这个但是......

第二期：

后来我使用master分支和build failed ...

重新创建了更改

Caused by: com.android.ddmlib.ShellCommandUnresponsiveException

你已经解决了问题的this版本，Sean Barbeau非常好地解释了这个问题：

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

并且您还修复了另一个需要更多时间的here和here解决的超时问题，see：

Android Gradle Plugin的硬编码超时值太低了。

Google修复了它（版本2.0.0-beta3）：

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

那么我们在build.gradle中放置什么来设置这个超时值？

目前它全部附加到android.adbOptions.timeOutInMs。

示例：Google项目Increasing ADB timeout和adding Travis-ci support。它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"
}

我将超时从1分钟增加到10分钟，就像马克麦克唐纳那样，以及构建passed：

Answer 2

尝试一些事情

确保已启动Emulator /已连接设备
使用$ adb kill-server
检查仿真器设置＆＃34;使用主机GPU＆＃34;已启用

无法配置travis在android项目上工作
