Category Secure Mobile Coding (Android)

The code sits there, harmless at first glance. But Android’s component system doesn’t forgive careless mistakes. One developer’s oversight with a Broadcast Receiver turned into a security nightmare last month. Just like that. Now everyone’s scrambling to patch holes they…

Opening up an Android APK feels like cracking open a safe these days. ProGuard and R8 work overtime turning our neat, organized code into something that looks like a cat walked across the keyboard. They don’t just scramble things though.…

Use the right security tools and techniques to guard against tapjacking on Android. Apply touch filtering and window configuration to prevent malicious overlays. Keep both apps and users safe by staying alert to new threats and keeping everything updated. Key…

Use JavaScript in Android WebView only when it’s absolutely necessary, defaulting to disabled to shrink your attack surface. Always sanitize both user and external input, and never expose sensitive native APIs through JavaScript interfaces, especially for untrusted content. Stick with…

Use HTTPS certificate pinning to lock Android apps to trusted servers. Tie your app to a specific certificate or public key hash, then verify every connection against this pin. If the server’s certificate or key doesn’t match, cut the connection,…

Use parameterized queries and validate every input. Restrict which columns and data are accessible through projection maps and strict mode. Encrypt sensitive fields and keep your content providers unexported unless you have an airtight reason. Key Takeaways Best Practices for…

Use the Android permissions model to protect both your users and your codebase. Always declare needed permissions in your manifest, check and request them at runtime with clear explanations, and never assume previous consent holds. Handle every user response respectfully…

Use explicit intents whenever you can to keep your app’s data away from prying eyes. Limit intent filters in your AndroidManifest and never use wildcards unless it’s absolutely necessary. Only request essential permissions, and always validate where intents come from…

Use internal storage for anything sensitive. Encrypt files before writing to external or shared locations, even if they seem harmless. We always rely on Android’s Keystore for managing keys, and newer scoped storage rules keep nosy apps out of your…
