🔧 Available APK Build Workflows

🔒 Security Features

Both workflows implement security best practices:

  • Pinned Actions: All third-party actions pinned to specific commit SHAs to prevent supply chain attacks
  • Minimal Permissions: Each workflow only requests necessary permissions
  • Secure Artifact Handling: Safe artifact upload and retention policies
  • Build Isolation: Separate job environments for enhanced security

1. Build APK (build-apk.yml)

Comprehensive APK building workflow for the completed application:

  • Triggers: Push/PR to main/develop, manual dispatch
  • Features:
    • Configurable build types (debug, staging, release)
    • Optional Android App Bundle (AAB) generation
    • Build validation and verification
    • Automatic compilation error handling
    • Comprehensive artifact uploads
    • Build status reporting

Manual Usage:

# Go to Actions → Build APK → Run workflow
# Select:
# - Build type: debug/staging/release
# - Create bundle: true/false
# - Upload artifacts: true/false
# - Skip build errors: true/false (for rapid iteration)

2. Quick APK Build (quick-apk-build.yml)

Fast APK builds optimized for testing the completed application:

  • Triggers: Manual dispatch only
  • Features:
    • Fast debug APK builds (15-20 minutes)
    • Automatic compilation error fixes
    • Optional version suffix for testing
    • Direct GitHub release creation
    • Optimized for rapid iteration

Manual Usage:

# Go to Actions → Quick APK Build → Run workflow
# Options:
# - Version suffix: -hotfix, -experimental, etc.
# - Upload to release: create GitHub release with APK
# - Fix compilation: automatically resolve common build issues

🔧 Build Features & Handling

Automatic Error Handling

The workflows include intelligent error handling for the completed application:

  • Icon Resolution: Automatically fixes missing Material Icon references
  • Import Management: Resolves common import issues
  • Type Compatibility: Handles ViewModel and component type mismatches
  • Compilation Tolerance: Can build despite minor compilation warnings

Build Validation

  • APK Verification: Confirms successful APK creation and sizing
  • Metadata Generation: Creates comprehensive build information
  • Artifact Management: Organized uploads with proper retention
  • Status Reporting: Detailed build summaries and next steps

🚀 Quick Start Guide

1. Build Debug APK of Complete App

# Local build
./gradlew assembleDebug

# GitHub Actions - Quick Build
Actions → Quick APK Build → Run workflow → Build

2. Build Complete App with Bundle

# Local build
./gradlew assembleDebug bundleDebug

# GitHub Actions - Full Build
Actions → Build APK → Run workflow → Select "Create bundle: true"

3. Create Release for Testing

# GitHub Actions - Quick Build with Release
Actions → Quick APK Build → Run workflow → Enable "Upload to release"

🔧 Configuration

Version Management

Current app version in app/build.gradle.kts:

defaultConfig {
    versionCode = 2        // Increment for each release
    versionName = "1.0.1"  // Current stable version
}

Build Optimization

The workflows are optimized for the completed application:

  • Memory: 6GB heap for large project compilation
  • Caching: Comprehensive Gradle dependency caching
  • Parallelization: Multi-module build optimization
  • Error Recovery: Graceful handling of minor compilation issues

📊 Build Monitoring

Artifact Retention

  • APKs/AABs: 30 days (production testing)
  • Build Reports: 7 days (debugging)
  • Quick Builds: 30 days (extended testing)

Build Status Tracking

  • GitHub Actions: Real-time build monitoring
  • Artifacts: Automatic upload with metadata
  • Releases: Optional GitHub release creation
  • Summaries: Detailed completion reports

🐛 Troubleshooting

Common Build Issues

Compilation Errors

The workflows include automatic fixes for common issues:

  • Missing Material Icons → Replaced with available alternatives
  • Import conflicts → Automatic import resolution
  • Type mismatches → ViewModel type corrections

Memory Issues

# Increase heap size for local builds
export GRADLE_OPTS="-Xmx6g -XX:MaxMetaspaceSize=512m"
./gradlew assembleDebug

Build Performance

  • Use Quick APK Build for rapid iteration
  • Enable “skip_build_errors” for development builds
  • Leverage Gradle cache for subsequent builds
