This Docker image contains the Android SDK and most common packages necessary for building Android apps in a CI tool like GitLab CI.
This version is based on the awesome gitlab-ci-android and in addition to it, it installs fastlane.
Make sure your CI environment's caching works as expected, this greatly improves the build time, especially if you use multiple build jobs.
A .gitlab-ci.yml with caching of your project's dependencies would look like this:
image: vratislav/gitlab-ci-fastlane-android
stages:
- build
before_script:
- export GRADLE_USER_HOME=$(pwd)/.gradle
- chmod +x ./gradlew
cache:
key: ${CI_PROJECT_ID}
paths:
- .gradle/
build:
stage: build
script:
- ./gradlew assembleDebug
artifacts:
paths:
- app/build/outputs/apk/app-debug.apk
