My Android game runs smoothly in the early stages but starts to slow down and eventually crash in several mid-game levels. The root of the problem appears to be performance-related bottlenecks that only surface in those specific areas. I need the crashes eliminated and the frame-rate stabilized so players can progress without interruptions. While you’re in the codebase, I also want to introduce a simple monetisation flow: a free trial build that lets new players experience the opening content, then offers an in-app purchase to unlock the full version. Google Play Billing integration, graceful trial limitations, and a clean “upgrade now” prompt are all part of the brief. Deliverables • Debug and optimise mid-game levels until no crashes occur on standard Android devices. • Create a trial version that locks content after the designated point. • Implement in-app purchase to unlock the full game, with purchase state persisting across reinstalls. • Supply a production-ready APK/AAB plus commented source code changes. If you’re comfortable profiling Android performance and wiring up Google Play Billing, I’d love to get this fix-and-upgrade published swiftly.

Hi there, I’ve reviewed your brief — mid-game slowdowns and crashes in specific levels, plus a request for a free-trial and Google Play Billing unlock. I’ll profile the problematic levels using Android Studio Profiler and Systrace, identify hotspots (GC spikes, allocation churn, heavy draw calls or physics bottlenecks), and apply targeted fixes: object pooling, texture/asset optimizations, level-specific memory fixes, and crash hardening. I’ll create a trial build that gracefully locks content at the chosen point, integrate Google Play Billing with durable purchase state (restore on reinstall), add a clean “upgrade now” prompt, and deliver a production-ready APK/AAB plus commented source changes. I can start immediately and aim to deliver an initial debugged test build within 7 days and the final integrated build shortly after. Best regards,

Hello Ibrahim, I hope you are doing well. I understand your Android game stalls and crashes in mid‑game, and you want a stable frame rate plus a monetization flow with a free trial and IAP to unlock the full game. I’ll profile the app with Android Profiler, memory monitors, and systrace to locate bottlenecks, then optimize the main loop, reduce allocations, improve asset streaming, and ensure consistent FPS across common devices. With 7+ years shipping Java Android games and integrating Google Play Billing, I’ll implement a clean trial flow: opening content is free, then players upgrade to unlock the rest, with purchase state persisting across reinstalls via the Billing Library. You’ll get a production-ready APK/AAB, commented source changes, and a robust test plan. Deliverables include crash-free mid‑game levels, a tested trial gating mechanism, seamless IAP integration, and release-ready assets. If you have a preferred test device set or Play Console configuration (test tracks, product IDs), I’ll align with it. I can start immediately and target 7–10 days depending on device coverage. Please feel free to contact me so we can discuss more details. I am looking forward to the chance of working together. Best regards,
