Android Security Standards

Priority: P0 (CRITICAL)

Implementation Guidelines

Data Storage

• Secrets: NEVER store API keys in code. Use EncryptedSharedPreferences for sensitive local data (Tokens).
• Keystore: Use Android Keystore System for cryptographic keys.

Network

• HTTPS: Enforce HTTPS via network_security_config.xml (cleartextTrafficPermitted="false").
• Pinning: Consider Certificate Pinning for high-security apps.

Component Export

• Exported: Explicitly set android:exported="false" for Activities/Receivers unless intended for external use.

Anti-Patterns

• No Sensitive Logs: Strip logs in Release builds.
• No Homebrew Root Detection: Use Play Integrity API instead.
• No Raw URL String Concatenation: Use Uri.Builder or HttpUrl (OkHttp) to prevent parameter injection.
