3. Continuous integration
•Every developer keeps his work-in-progress continually integrated with every other developer
•Requires build to be automated and self- testing
•Makes results of the latest build visible

6. Travis CI: overview
•Hosted, open-source
•GitHub-only integration
•Free for public GitHub repositories, starting from $129/mo for private ones
•Easy to setup: always one .travis.yml file
•Officially supports Android platform since 2014
6

7. Travis CI: setup
•Hosted Travis Webapp setup, add your GitHub account
•.travis.yml configuration file
•Validate your configuration file http://lint.travis-ci.org/ [yaml syntax]
7

8. Travis CI: configuration options (1)
•Programming language your project uses
•Commands/scripts you want to be executed before each build (e.g. install dependencies)
•Command is used to run test suite
•Emails, Campfire and IRC rooms to notify about failures
8

9. Travis CI: configuration options (2)
•Code coverage (for Java/Android): external hosted tool Coveralls, uses JaCoCo reports, from $5/mo
•Limited functionality in uploading artifacts, but friendly with Amazon S3
•Scheduled builds only by external tool
9

10. Travis CI: configuration example
language: android android: components: # The BuildTools version used by your project - build-tools-19.1.0 # The SDK version used to compile your project - android-19 before_install: - chmod +x gradlew install: - ./gradlew assemble script: - ./gradlew test # For Robolectric tests
10

11. Circle CI: overview
•Hosted service
•GitHub-only integration
•Starts from $19/mo
•Easy to setup: 2 additional files for Android
•SSH access to build VM for 30 minutes after build
11

12. •What programming language your project uses
•What commands/scripts you want to be executed before each build (e.g. install dependencies)
•What command is used to run test suite
•Artifacts to collect
•Nightly builds (using extra script)
12
Circle CI: configuration options

13. Circle CI: configuration (1): circle.yml
13
machine: environment: ANDROID_HOME: /usr/local/android-sdk-linux dependencies: cache_directories: - ~/.android - ~/android override: - bash install-dependencies.sh test: override: - chmod +x gradlew - ./gradlew assemble test
Looks like Travis CI, doesn’t it?

14. Circle CI: configuration (2): dependencies script
export PATH="$ANDROID_HOME/platform- tools:$ANDROID_HOME/tools:$PATH" DEPS="$ANDROID_HOME/installed-dependencies" if [ ! -e $DEPS ]; then echo y | android update sdk -u -a -t android-19 && echo y | android update sdk -u -a -t platform-tools && echo y | android update sdk -u -a -t extra && echo y | android update sdk -u -a -t build-tools-19.1.0 && touch $DEPS fi

15. Jenkins: overview
•Hudson  Jenkins
•Open-Source
•Java WebApp in container
•Should be hosted on your private server
•Multiple users, matrix permissions
15

16. Jenkins: setup
•Network-enabled server
•Install Jenkins bundle with servlet container
•Install Android SDK and support repos
•Add Jenkins plugins for Git, Gradle etc.
•Add your Git keys
16

17. •Extremely flexible
•Hundreds of plugins
