This Docker image contains the Android SDK and most common packages necessary for building Android apps in a CI tool like GitLab CI. 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: jangrewe/gitlab-ci-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
