Travis模拟器在android-wait-for-emulator之后停止

Question

嗨，我有下一个 travis 配置：

语言：安卓

env:
  global:
  - JAVA8_HOME=/usr/lib/jvm/java-8-oracle
  - TERM=dumb

jdk:
  - oraclejdk8

android:
  components:
   - platform-tools
   - tools
   - build-tools-23.0.1
   - build-tools-22.0.1
   - android-23
   - android-22
   - extra
   - extra-android-support
   - extra-google-google_play_services
   - extra-google-m2repository
   - extra-android-m2repository
   - addon-google_apis-google-23
   - addon-google_apis-google-22

before_script:
  - echo no | android create avd --force --name test --target android-21 --abi armeabi-v7a
  - emulator -avd test -no-skin -no-audio -no-window -gpu off -no-boot-anim &
  - android-wait-for-emulator
  - adb shell input keyevent 82 &

script:
  - ./gradlew :projectcore:checkstyle
  - ./gradlew clean build -x lint
  - ./gradlew :project:connectedAndroidTest

好的，如果我运行这个，下载所有依赖项，但是当运行模拟器时停止它。

emulator -avd test -no-skin -no-audio -no-window -gpu off -no-boot-anim &
$ android-wait-for-emulator

Failed to Initialize backend EGL display
emulator: WARNING: Could not initialize OpenglES emulation, using software renderer.
No output has been received in the last 10m0s, this potentially indicates a stalled build or something wrong with the build itself.

我不知道这是什么问题：S，有人对这个问题有任何线索吗？如果我删除 android-wait-for-emulator 继续执行但测试失败，因为模拟器尚未连接（有道理）。想法？

Answer 1

我发现了问题：尝试安装时platform-tools，Travis 无法移动文件夹，因为文件夹存在并删除了文件夹内容，这个文件夹是platforms-tools，其中包含adb命令，这解释了为什么android-wait-for-emulator失败。

解决方案是从components部分中删除- platform-tools和，因为默认情况下已经提供了。- tools

修复这个问题很困难，我相信这对任何人都有用。
