Android Deployment Standards

Priority: P0 (CRITICAL)

Implementation Guidelines

Build Configuration

• Minification: Always enable isMinifyEnabled = true and isShrinkResources = true for Release builds (R8).
• Format: Publish using App Bundles (.aab) for Play Store optimization.
• Signing: NEVER commit keystores or passwords. Use Environment Variables / Secrets.

Proguard / R8

• Rules: Keep rules minimal. Use annotations (@Keep) for reflection-heavy classes instead of broad wildcard rules.
• Mapping: Upload mapping.txt to Play Console for crash de-obfuscation.

Anti-Patterns

• No debuggable=true in Release: Breaks obfuscation and exposes internal logic.
• No Secrets in Repo: Use local.properties or CI environment variables.
