Can't configure travis to work on android project

Question

I have found several problems with Travis CI and I have been solving them but the last one I can't.

I'm getting the common error com.android.ddmlib.InstallException: Failed to establish session

This is my travis file:

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

And this is my travis output: https://travis-ci.org/GarceGon/SimpleLock/builds/139367600

Solution:

Delete -no-boot-anim option to wait for emulator ready and increase timeout to 10 minutes.

First issue:

Replace

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

By

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

Deleting -no-boot-anim option, android-wait-for-emulator script depends on boot animation to detect when the emulator is ready as I explain here.

I forked your project to confirm this on a develop branch and the Travis-CI build passed but...

Second issue:

Later I recreated the change using the master branch and the build failed...

Caused by: com.android.ddmlib.ShellCommandUnresponsiveException

You already fixed this version of the issue very well explained by Sean Barbeau:

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

and you also fixed another timeout issue explained here and here that needs more time, 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"
}

I increased the timeout from 1 to 10 minutes like Mark McDonald did, and the build passed:

Still not working for me :( https://travis-ci.org/GuilhE/SharedPrefsUtils/builds/449764851 using Gradle Plugin 3.2.1 — GuilhE, Nov 02 '18 at 10:45

Try few things

Make sure that Emulator is launched / Device is connected
Restart adb with $ adb kill-server
Check that emulator setting "Use Host GPU" is enabled
