Mobile Auction Auto-Bidder App

I need a streamlined Android application that can jump into a Savage Survival in-game auction at the last possible moment, place my pre-set bid automatically, and confirm the win.

Here is what matters most to me:

• The app runs exclusively on Android and works smoothly on recent versions of the OS.
• I simply enter the item ID, my maximum bid, and the seconds-before-close I want the snipe to fire; the app handles the rest in the background.
• A concise activity log records each attempt, showing the exact time the bid was sent and the server response so I can verify performance.
• Authentication to the Savage Survival auction endpoint should be handled securely, storing tokens or credentials with proper encryption.
• If an auction ends early or a network issue blocks the bid, I want a clear on-screen alert so I know to act manually next time.

Deliverables:
• Production-ready APK and full source (Kotlin or Java) with build instructions.
• README that explains any required keys, endpoints, or config files so I can slot in my own credentials and recompile if the game updates.
• Brief test report showing at least three successful automated bids in a live or staging environment.

If you have prior experience with auction snipers, game APIs, or low-latency Android networking, tell me how you’ll tackle it and how soon you can ship a working prototype.
