Project description:
"I have an existing Android app that has been running reliably for a few years, but it lacks the modern security protections today’s users expect. I want to keep the current interface intact and instead focus on building brand-new features that strengthen the app’s security layer.

Here’s what I’m looking for: I’ll share the full source once we start, and I’d like you to review the current codebase, identify weak points, then implement new security-oriented functionality. Exactly which defences we add—biometric login, advanced encryption, secure networking, Play Integrity checks, obfuscation, or other best-practice techniques—is open for discussion; I’m happy to hear your recommendations as long as the end result is a demonstrable security upgrade.

Deliverables
• Updated Android Studio project with the agreed security features fully integrated
• A short change log explaining what was added or refactored
• A buildable release APK for testing, plus any required keystore updates
• Brief implementation notes so I can maintain the new modules going forward

If you’ve previously hardened Android apps or integrated advanced security libraries, your insight will be invaluable. Let’s make this app safer for every user." (client-provided description)
