# Android Deployment Standards

## **Priority: P0**

## 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

- **Debug in Release**: `**No Debug Flags**: Ensure debuggable = false.`
- **Hardcoded Secrets**: `**No Secrets in Repo**: Use local.properties or Env Vars.`
