Android Legacy Security Standards

Priority: P0 (CRITICAL)

1. Secure Intents and Components

  • Set android:exported="false" for all internal Activities/Services unless needed for deep links.
  • Verify resolveActivity before starting implicit intents.
  • Treat all incoming Intent extras as untrusted — validate all schema/data types.

See hardening examples for manifest and component restrictions.

2. Lock Down WebViews

  • Default to javaScriptEnabled = false. Use WebViewClient and WebChromeClient to restrict navigation.
  • Disable allowFileAccess and allowFileAccessFromFileURLs to prevent local file theft via XSS.
  • If using @JavascriptInterface (API 17+), strictly limit exposed API surface.

See hardening examples for WebView lockdown patterns.

3. Protect Storage and Files

  • NEVER expose file:// URIs. Use FileProvider to generate content:// URIs with temporary permissions.
  • Use EncryptedSharedPreferences for auth tokens and PII. Never use legacy public-read file modes.
  • Use NetworkSecurityConfig to disable cleartextTrafficPermitted and implement certificate pinning.

Anti-Patterns

  • No Implicit Intents Internally: Use explicit intents with component class name.
  • No Public Read Modes: Never expose SharedPreferences or files with global read access.
