I have an existing Android APK that I’d like to customize and improve. The job is entirely about modding: de-compiling, adjusting the code or resources, then re-compiling and signing a clean, working build that can be installed right away. The scope is threefold. First, refine the current UI/UX so the screens feel modern and intuitive. Second, bolt on several new features that I will outline once we start; they touch both front-end layout and some basic background logic. Third, strip out every ad unit and any in-app purchase hooks, leaving nothing that calls external ad networks or paywalls. You must be comfortable with typical Android modding workflows—apktool, JADX, Smali, Android Studio, signing keys—and know how to keep the original app’s core functionality fully intact. Deliverables I expect: • Fully working, ad-free APK reflecting the new UI/UX and added features • All modified source or rebuild scripts so I can generate future builds myself • A short change-log describing what was altered and where Clear, concise communication is key; the sooner we iterate, the sooner we ship. If you have a solid track record modding Android apps, I’m ready to get started right away.

Your project is more than a UI refresh: the key challenge is modifying an existing APK while preserving its current behavior, removing ad/IAP code cleanly, and producing a reproducible signed build. I’d first inspect the APK with JADX/apktool, map the UI, resources and background flows, and identify ad/IAP SDKs and their call paths. Then I’d make the UI and feature changes, remove the monetization components without breaking dependencies, rebuild, sign, and test the resulting APK. I’d also document the modified areas and provide the rebuild setup requested. One important point before estimating: do you own or have authorization to modify and redistribute this APK, and do you have the original signing key/source if available? That affects what can be preserved and whether the result can be installed as an update versus a separate build. If you share the APK and the planned feature list, I can assess the current structure and give you a realistic implementation plan. Best, Jenifer

Hello, I’m an Android/Flutter developer with strong experience in application debugging, UI improvements, API integration, and Android build/release workflows. I understand that this project requires working with an existing APK, analyzing its structure, modifying resources or code where appropriate, removing ad and purchase-related components, then rebuilding and signing a clean installable version. I can work on: * UI/UX improvements and resource modifications * APK analysis and code/resource inspection * Adding the requested features * Removing ad-related components and IAP hooks * Preserving the application’s existing functionality * Rebuilding and signing the final APK * Testing installation and core functionality * Providing modified project files/scripts and a clear change log My approach would be to first inspect the APK and identify its architecture, dependencies, permissions, ad/IAP integrations, and modification points before making changes. I’ll then test each change to avoid breaking existing functionality. I’m comfortable working with Android Studio, APK build/signing workflows, and debugging unfamiliar Android projects, and I can quickly adapt to the specific structure of the application. I’m available to start and can review the APK and requested feature list first, then provide a realistic timeline and fixed-price estimate. Best regards, Android / Flutter Developer

As an experienced mobile developer specializing in modern Android development, I can handle the entire scope—whether it involves decompiling and modifying Smali/resources for specific tweaks, or rebuilding and structuring features cleanly. However, since you mentioned modernizing the UI/UX and adding new features, I would strongly recommend a cleaner and much faster approach: rebuilding the necessary parts (or the core UI) from scratch using Kotlin and Jetpack Compose (Google's modern declarative UI toolkit and the successor to legacy Java/XML views). This ensures the app looks exceptionally modern, runs smoothly, has zero legacy technical debt, and makes adding new features and removing ads/paywalls much easier and more maintainable. Here is how I will approach your deliverables: Ad & Paywall Removal: Strip out all ad network SDKs, trackers, and in-app purchase hooks from the original package. Modern UI/UX & New Features: Implement the requested layout improvements, Material 3 design, Dark Mode, and new features natively in Kotlin and Jetpack Compose. Source & Build Scripts: Provide all source code, clean project files, and Gradle build scripts so you can easily generate future builds yourself. Change-Log: Include a detailed breakdown of all modifications, removed SDKs, and newly added features. Let's get started—feel free to share the APK file and the list of new features whenever you're ready.
