Don’t Trust the Device: A Developer’s Guide to Secure Mobile Apps

Key Takeaways
1-Don’t trust the device — design your app assuming the environment is hostile.
2- Secure early — architecture & decisions made before coding matter the most.
3- Use platform security — Keystore, integrity checks, and server-side validation.
4- Protect app components — validate intents, deep links, and exposed surfaces.
5- Enable runtime defense — detect root, hooking, overlays, and abuse signals.
