Travis CI for Android

Question

Trying to get started with Travis CI for my Android projects. First I set up dummy project with Android Bootstrap, and added a the yml file from square's otto project - modified to have my username and repo name.

My build fails with the error "/home/travis/build.sh: line 94: android: command not found, even when square's project builds fine.

The error seems to indicate that the path isn't set properly, in spite of having these lines in my .travis.yml

• export ANDROID_HOME=~/builds/f2prateek/FoodBot/android-sdk-linux
• export PATH=${PATH}:${ANDROID_HOME}/tools:${ANDROID_HOME}/platform-tools

Is there something else I need to be setting up to get this right?

Update 2014/05: Travis CI now has official support for Android.

http://docs.travis-ci.com/user/languages/android/

The workarounds below are not required anymore, unless you want to use it on a non-Android VM.

The issue is most likely with the fact that Travis CI switched over to 64-bit virtual machines. You need to install ia32-libs for Android to run in a 64-bit environment. This can currently be achieved with:

sudo apt-get install -qq --force-yes libgd2-xpm ia32-libs ia32-libs-multiarch

I wrote a blog post on getting Android builds running on Travis, which covers this as well as other details: http://rkistner.github.com/android/2013/02/05/android-builds-on-travis-ci/

Travis might support Android-specific virtual machines in the future, which will simplify the configuration. Follow the conversation on issue #56 for updates on this issue and discussions on the Android-specific VM.

This reply covers up to Travis automatic testing. See the Medium article for the complete version: automatic testing and deployment.

Travis CI (@ API 26+)

Apparently from API 24 setting up the emulator is a pain on Travis is a pain[1][2][3][4].

Sean Barbeau, who's been digging through this for a lot more time than I have, has pretty much considered it impossible to emulate.

But there is a working and simpler alternative for API 26+, which is running the tests with gradlew instead of the adb emulator. It seems to have some limitations, but it should work. Credits to PocketHub.

Environment variables that you might have to adapt to your project ones:

Some information should be available either in the build.gradle or AndroidStudio -> Settings -> Android SDK -> SDK Tools

(if you're building a new project with an updated AndroidStudio you should just pick the latest versions in the following links)

ANDROID_BUILD_TOOLS: https://developer.android.com/studio/releases/build-tools.html

Example .travis.yml setup (with autodeploy to GitHub releases).
