Agent Skills: Android Security Standards

Secure Data Encryption, Network Security, and Permissions on Android. Use when handling API keys, auth tokens, cleartext traffic, android:exported, EncryptedSharedPreferences, certificate pinning, or root detection — even if the user just asks 'is this secure'. (triggers: network_security_config.xml, AndroidManifest.xml, EncryptedSharedPreferences, cleartextTrafficPermitted, intent-filter, api key, token storage, certificate pinning, root detection, secure storage)

Skill Metadata

Name

Description
Secure data encryption, network configuration, and permissions in Android apps. Use when handling API keys, auth tokens, certificate pinning, EncryptedSharedPreferences, or securing exported components.

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.
