Android Deployment & CI

Build Types

Debug Build

./gradlew assembleDebug
# Output: app/build/outputs/apk/debug/app-debug.apk

• Auto-signed with debug keystore
• Suitable for local testing and CI verification

Release Build

./gradlew assembleRelease
# Output: app/build/outputs/apk/release/app-release.apk

• Requires signing config in build.gradle.kts
• ProGuard/R8 enabled for minification
• Generate signed bundle: ./gradlew bundleRelease

AAB (Android App Bundle)

./gradlew bundleRelease
# Output: app/build/outputs/bundle/release/app-release.aab

• Preferred format for Play Store distribution
• ~40% smaller than universal APK

Code Signing

Keystore Setup

// signing.gradle.kts
android {
    signingConfigs {
        create("release") {
            storeFile = file("../keystore/release.keystore")
            storePassword = System.getenv("KEYSTORE_PASSWORD")
            keyAlias = System.getenv("KEY_ALIAS")
            keyPassword = System.getenv("KEY_PASSWORD")
        }
    }
}

Best Practices

• Store keystore encrypted in CI secrets, never in git
• Use different keystores for staging vs production
• Rotate keys annually, migrate gracefully via Play Console

CI/CD Pipeline (via Workflow)

The android-build-test-deploy workflow orchestrates:

1. Build → Gradle MCP assembles APK
2. Test → Unit + instrumented via Gradle + Mobile MCP
3. Deploy → Release build with signing, upload to Play Store

For full pipeline, run: /workflow android-build-test-deploy

Tauri Mobile Distribution

• Tauri generates Android project at src-tauri/gen/android/
• Build Tauri Android: cargo tauri android build
• The resulting APK is at src-tauri/gen/android/app/build/outputs/apk/
• Tauri bundles Rust binary inside the APK — no separate distribution needed
