Android Workflow Internal

Android Internal Track Workflows (Option D - Split)

Generates two separate GitHub Actions workflows following Option D architecture:

1. build.yml - CI only (build & test on every push/PR)
2. release-internal.yml - Manual releases with version management

Clear separation of concerns:

• CI validates code quality automatically
• Releases are always intentional (manual trigger)
• Version management integrated into release process
• No accidental deployments

Prerequisites

• Service account setup complete
• Package name known

Inputs

Process

Step 1: Verify Fastlane Setup

Ensure Fastlane is configured by running /devtools:android-fastlane-setup first.

Verify setup:

bundle exec fastlane lanes

Expected output should show deploy_internal lane.

Step 2: Verify Metadata Structure

Ensure Fastlane metadata exists:

ls fastlane/metadata/android/en-US/

If missing, run /devtools:android-fastlane-setup.

Step 3: Create Workflow Directory

mkdir -p .github/workflows

Step 4: Create Build Workflow (CI)

Create .github/workflows/build.yml:

name: Build & Test

on:
  push:
    branches: [main]
  pull_request:
    branches: [main]

jobs:
  build:
    runs-on: ubuntu-latest
    steps:
      - name: Checkout code
        uses: actions/checkout@11bd71901bbe5b1630ceea73d27597364c9af683  # v4.2.2

      - name: Set up JDK 17
        uses: actions/setup-java@c5195efecf7bdfc987ee8bae7a71cb8b11521c00  # v4.7.0
        with:
          java-version: '17'
          distribution: 'temurin'

      - name: Setup Gradle cache
        uses: actions/cache@1bd1e32a3bdc45362d1e726936510720a7c30a57  # v4.2.0
        with:
          path: |
            ~/.gradle/caches
            ~/.gradle/wrapper
            .gradle/configuration-cache
          key: gradle-${{ runner.os }}-${{ hashFiles('**/*.gradle*', '**/gradle-wrapper.properties') }}
          restore-keys: |
            gradle-${{ runner.os }}-

      - name: Setup Gradle
        uses: gradle/actions/setup-gradle@v4

      - name: Build
        run: ./gradlew assembleRelease

      - name: Run Unit Tests
        run: ./gradlew test

      - name: Upload Test Results
        if: always()
        uses: actions/upload-artifact@ea165f8d65b6e75b540449e92b4886f43607fa02  # v4.6.0
        with:
          name: test-results
          path: app/build/reports/tests/
          retention-days: 7

Purpose: CI only - validates code quality, no deployment.

Step 5: Create Release Workflow (Manual)

Create .github/workflows/release-internal.yml:

name: Release to Internal Track

on:
  workflow_dispatch:
    inputs:
      version_bump:
        description: 'Version bump type'
        required: true
        type: choice
        options:
          - patch
          - minor
          - major
        default: 'patch'

jobs:
  release:
    runs-on: ubuntu-latest
    permissions:
      contents: write  # For pushing commits and tags
    steps:
      - name: Checkout code
        uses: actions/checkout@11bd71901bbe5b1630ceea73d27597364c9af683  # v4.2.2
        with:
          fetch-depth: 0  # Full history for tags
          token: ${{ secrets.GITHUB_TOKEN }}

      - name: Set up JDK 17
        uses: actions/setup-java@c5195efecf7bdfc987ee8bae7a71cb8b11521c00  # v4.7.0
        with:
          java-version: '17'
          distribution: 'temurin'

      - name: Setup Gradle cache
        uses: actions/cache@1bd1e32a3bdc45362d1e726936510720a7c30a57  # v4.2.0
        with:
          path: |
            ~/.gradle/caches
            ~/.gradle/wrapper
            .gradle/configuration-cache
          key: gradle-${{ runner.os }}-${{ hashFiles('**/*.gradle*', '**/gradle-wrapper.properties') }}
          restore-keys: |
            gradle-${{ runner.os }}-

      - name: Setup Gradle
        uses: gradle/actions/setup-gradle@v4

      - name: Calculate Version
        id: version
        run: |
          chmod +x scripts/gradle-version.sh
          scripts/gradle-version.sh generate ${{ inputs.version_bump }}

      - name: Update version.properties
        run: |
          scripts/gradle-version.sh update ${{ steps.version.outputs.version }}

      - name: Commit Version Bump
        run: |
          git config user.name "github-actions[bot]"
          git config user.email "github-actions[bot]@users.noreply.github.com"
          git add version.properties
          git commit -m "chore: release v${{ steps.version.outputs.version }}"
          git push origin main

      - name: Decode Keystore
        env:
          ENCODED_KEYSTORE: ${{ secrets.SIGNING_KEY_STORE_BASE64 }}
        run: |

      - name: Upload Artifact
        uses: actions/upload-artifact@ea165f8d65b6e75b540449e92b4886f43607fa02  # v4.6.0
        with:
          name: release-${{ steps.version.outputs.tag }}
          path: app/build/outputs/bundle/release/app-release.aab
          retention-days: 90

      - name: Create Git Tag
        run: |
          git tag -a ${{ steps.version.outputs.tag }} -m "Release ${{ steps.version.outputs.version }}"
          git push origin ${{ steps.version.outputs.tag }}

          bundler-cache: true

        run: echo "${{ secrets.SERVICE_ACCOUNT_JSON_PLAINTEXT }}" > service-account.json

      - name: Deploy with Fastlane

        run: bundle exec fastlane deploy_internal

      - name: Cleanup
        if: always()
        run: |
          rm -f app/release.jks
          rm -f service-account.json

      - name: Release Summary
        run: |
          echo "## Release Complete" >> $GITHUB_STEP_SUMMARY
          echo "" >> $GITHUB_STEP_SUMMARY
          echo "| Property | Value |" >> $GITHUB_STEP_SUMMARY
          echo "|----------|-------|" >> $GITHUB_STEP_SUMMARY
          echo "| Version | ${{ steps.version.outputs.version }} |" >> $GITHUB_STEP_SUMMARY
          echo "| Tag | ${{ steps.version.outputs.tag }} |" >> $GITHUB_STEP_SUMMARY

          echo "3. Add internal testers if needed" >> $GITHUB_STEP_SUMMARY

Purpose: Manual releases with version management - always intentional, never automatic.

Key differences from combined approach:

• ✅ Clear separation: CI validates code, Release deploys
• ✅ Version management integrated into release workflow
• ✅ Commits version bump before building
• ✅ Creates git tags as part of release process
• ✅ Release is always manual (workflow_dispatch only)
• ✅ Build/test runs on every PR and push (no deployment)
• ✅ No accidental deployments on regular commits

Verification

MANDATORY: Validate both workflows:

# Validate YAML syntax
yamllint .github/workflows/build.yml
yamllint .github/workflows/release-internal.yml

# Verify workflows exist
test -f .github/workflows/build.yml && echo "✓ Build workflow created"
test -f .github/workflows/release-internal.yml && echo "✓ Release workflow created"

# Verify Fastlane commands
grep "fastlane deploy_internal" .github/workflows/release-internal.yml

Expected output:

• ✓ Build workflow created
• ✓ Release workflow created
• Fastlane deploy command found

Outputs

How to Use

Continuous Integration (Automatic)

Every push to main or PR triggers build.yml:

• Builds the app
• Runs unit tests
• Uploads test results

No deployment - just validation.

Release to Internal Track (Manual)

1. Go to Actions → Release to Internal Track
2. Click Run workflow
3. Select version bump type (patch/minor/major)
4. Click Run workflow

What happens:

1. Calculates next version from git tags
2. Updates version.properties
3. Commits version bump
4. Creates git tag
5. Builds release bundle
6. Deploys to Play Store internal track

Workflow Separation Benefits

✅ Clear intent: CI validates, releases deploy ✅ No accidents: Releases are always manual ✅ Version control: Version bumps committed before release ✅ Git tags: Automatic tag creation on release ✅ Fast CI: Build/test runs quickly without deployment overhead ✅ Audit trail: Clear history of releases vs. regular commits

Troubleshooting

"YAML syntax error"

Cause: Invalid YAML format Fix: Check indentation (use spaces, not tabs)

"Workflow not triggering"

Cause: Build workflow not running on push Fix: Verify branch name in workflow matches your main branch (main or master)

"Version calculation fails"

Cause: version-manager.sh script not found or not executable Fix: Run /devtools:version-management first to setup version scripts

Completion Criteria

• .github/workflows/build.yml exists and is valid
• .github/workflows/release-internal.yml exists and is valid
• Fastlane configured (bundle exec fastlane lanes works)
• Metadata exists in fastlane/metadata/android/en-US/
• Version management scripts available
• Build workflow runs on push/PR
• Release workflow available for manual trigger
