使用Gradle的Travis-CI Android测试可以防止超时

Question

I'm trying to build & test my project on Travis CI. It keeps showing me same repetitive output every time on all my repositories.

Here is my travis.yml https://github.com/carts-uiet/cartsbusboarding/blob/master/.travis.yml

language: android
    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
    - build-tools-21.0.0
    # The SDK version used to compile your project
    - android-21
    # Additional components
    - add-on
    - extra
    # Specify at least one system image,
    # if you need to run emulator(s) during your tests
    - sys-img-armeabi-v7a-android-21
    # Emulator Management: Create, Start and Wait
    before_script:
    - echo no | android create avd --force -n test -t android-21 --abi armeabi-v7a
    - emulator -avd test -no-skin -no-audio -no-window &
    - android-wait-for-emulator
    - adb shell input keyevent 82 &

Here is one such build https://travis-ci.org/carts-uiet/cartsbusboarding/builds/39447907

$ javac -version
javac 1.7.0_60
before_script.1
3.53s$ echo no | android create avd --force -n test -t android-21 --abi armeabi-v7a
Android 5.0 is a basic Android platform.

with the following hardware config:

hw.ramSize=512
vm.heapSize=48
before_script.2
0.01s
$ emulator -avd test -no-skin -no-audio -no-window &
$ android-wait-for-emulator

All these builds time-out.

What am I doing wrong here?

Answer 1

Updated response: VM images already include fixed android-wait-for-emulator script and android SDK tools version 24.0.0 by default solving this issue. I deleted my outdated response and workaround.

Answer 2

This sounds like the best alternative to get the latest version of the script:

I added this to my before script:

# Emulator Management: Create, Start and Wait
before_script:
  - echo no | android create avd --force -n test -t android-21 --abi armeabi-v7a
  - emulator -avd test -no-skin -no-audio -no-window &
  - curl http://is.gd/android_wait_for_emulator > android-wait-for-emulator
  - chmod u+x android-wait-for-emulator
  - ./android-wait-for-emulator
  - adb shell input keyevent 82 &

The url points to the latest script available on github.

Hope that helps . . .

You need to instruct your travis build to actually run unit tests:

# run tests  against the emulator
- ./gradlew connectedAndroidTest
# run tests  against the JVM
- ./gradlew test
