Travis and Android

If you're looking to build your Android app on Travis CI, using SDK r22.3 and API 19 (Android 4.4), put this in configuration file .travis.yml :

language: java
before_install: 

  # install necessary x32-libs for Android SDK 

  - sudo apt-get update -qq

  - sudo apt-get install -qq libstdc++6:i386 lib32z1
  # download the latest android sdk and unzip 

  - wget http://dl.google.com/android/android-sdk_r22.3-linux.tgz

  - tar -zxf android-sdk_r22.3-linux.tgz
  - export ANDROID_HOME=`pwd`/android-sdk-linux

  - export PATH=${PATH}:${ANDROID_HOME}/tools:${ANDROID_HOME}/platform-tools
# only update the sdk for the tools and platform-tools and required api level
  # (run "android list sdk --extended" to get the full list)
  - echo "y" | android update sdk --filter tools,platform-tools,build-tools-19.0.0,android-19 --no-ui --force

Up to date version is here.

What it does (and why):

• The Travis virtual machines are running 64 bit kernels, but the Android SDK needs 32 bit, so packages libstdc++6:i386 and lib32z1 are needed.
• The Android SDK is not installed on the Travis instance, so you need to download and install it yourself.
• Update the tools and platform-tools and API (here API 19) related packages.
• There is no command line option to accept the license, so piping a "y" to the installer is necessary. Please note : if you have to accept multiple licences, this will not work.

Update (08Dec2013) : Only install required x32 packages, use names of SDK packages

Thanks to Levi Wilson and Ralf Kistner for inspiration to get it working.
