Developer Request: Reverse Engineering Existing Google Play App I am looking for an experienced developer who can help recover or reconstruct the source code of a mobile game that is currently published in my Google Play Console. Unfortunately, I no longer have access to the original editable source files. My understanding is that it may be possible to reverse engineer the published APK or app bundle from Google Play into a readable codebase (likely C++ or another compiled format), and then rebuild it into a usable project that can be edited again. The goal of this project is to: Extract or reconstruct the existing app’s code from the Google Play version Convert it into an editable development project (Android Studio or similar) Fix any issues within the recovered code Rebuild the app as a new updated version Replace assets and add new features If full reverse engineering is not possible, I’m also open to partial recovery solutions or rebuilding the project structure based on what can be extracted. Please contact me if you: Have experience reverse engineering Android APK/AAB files Understand code reconstruction workflows Can help recreate an editable version of the project Can assist with improving and relaunching the game as a new release , this job only pays 50 to a $100 as this is not a 100% necessity. I was just curious if it was able to be done. And if it is that's great, if not, I'm not stressing it. So please do not ask for more funds if you can't work within myolotted budget I’m looking to move forward as soon as possible with the right developer.

Hi, I’m Abhishek Rathore, a senior mobile engineer. You want to recover/reconstruct a published Google Play game into an editable project, even if partial recovery is the only viable path—I can handle that realistically. ? Approach - Extract APK/AAB using JADX + APKTool to recover Java/Kotlin layers and resources - Analyze native parts (if any) via Ghidra/NDK symbols for C++ reconstruction - Rebuild a clean Android Studio project (Gradle-based) with recovered assets - Refactor obfuscated code into maintainable modules where possible ✅ Core Features - Decompiled source recovery (Java/Kotlin + XML assets) - Resource extraction (images, sounds, configs) - Partial native logic reconstruction (if used) - Rebuild into Android Studio project - Fix compile/runtime issues - Prep for feature additions and updates ☁️ Reliability / Performance - Handle ProGuard/R8 obfuscation limits with mapping heuristics - Validate game loops, asset loading, and memory usage post-rebuild - Flag unrecoverable logic early to avoid wasted effort ? Deliverables - Working Android Studio project - Cleaned and structured codebase - Build-ready APK - Notes on recovered vs recreated components ? Why Me I’ve reconstructed and relaunched legacy Android games where source was lost, including partial native recovery. Can you confirm if the app uses Unity, Unreal, or native Android/NDK?

⭐⭐⭐⭐⭐ ✅Hi there, hope you are doing well! I have previously worked on recovering source code from published Android apps by decompiling APKs and reorganizing the code into editable Android Studio projects with minimal complications. The most important part for success is accurately reconstructing the project structure and dependencies to ensure smooth editing and rebuilding. Approach: ⭕ Analyze the provided APK/AAB to extract as much source code and resources as possible ⭕ Reconstruct an editable Android Studio project with recovered code ⭕ Identify and fix issues in the recovered code to ensure functionality ⭕ Help replace assets and implement new features per your requirements ⭕ Deliver a stable version ready for your updates and relaunch ❓ Could you please confirm whether you can provide the APK file or access to the Google Play Console to download it? ❓ Are there any specific new features you have in mind to prioritize after recovery? I am confident my experience with Android reverse engineering and rebuilding apps will help you recover or partially reconstruct your game source quickly and within your budget. Thank you and looking forward to working with you. Best regards, Nam

Hi, My name is Shivam, and I have over 10 years of experience in Android development, including working with APK analysis, decompilation, and partial code reconstruction. I want to be upfront—full recovery of the original source code from a published APK/AAB is usually not possible. Decompiled code (using tools like JADX or APKTool) can provide a readable structure, but it is often obfuscated, incomplete, and not directly usable as a clean development project. Games built with engines or C++ (NDK) are especially difficult to fully reconstruct. However, within your budget, I can help with a practical approach: • Extract available resources (images, assets, layouts, basic logic where possible) • Decompile and analyze the APK to understand app flow and structure • Recreate a clean Android Studio project based on the recovered logic • Fix issues and prepare the app for a fresh release • Assist with replacing assets and adding simple improvements This approach focuses on rebuilding rather than perfectly recovering, which is more reliable and maintainable long-term. I understand your budget constraints ($50–$100) and can offer a limited-scope recovery + analysis within that range, along with clear guidance on what can realistically be achieved. If you’d like, you can share the app link or APK, and I’ll quickly assess feasibility before we proceed. Looking forward to helping you move this forward. Sincerely, Shivam

Hello, I’ve reviewed your requirement and understand you’re looking to recover or reconstruct the source code of an Android game from an existing Google Play release, ideally by decompiling or reverse engineering the APK/AAB into a usable, editable project. I have 8+ years of experience working with Android app debugging, APK analysis, code recovery workflows, and rebuilding legacy projects when original source files are unavailable. My approach would be: • Extract and analyze the APK/AAB using standard reverse engineering tools (where legally and technically possible) • Reconstruct project structure into a readable Android Studio format • Recover Java/Kotlin logic and identify obfuscated or compiled components • Rebuild missing project configuration (Gradle, manifests, dependencies) • Restore assets and resources into a clean, runnable project structure • Test and fix runtime issues to ensure the rebuilt app launches correctly • Provide guidance on limitations (as some native/C++ or heavily obfuscated code may not be fully recoverable) I WILL DELIVER THE MAXIMUM POSSIBLE RECOVERY OF YOUR EXISTING APP INTO A USABLE AND EDITABLE ANDROID STUDIO PROJECT, WITH CLEAR NOTES ON WHAT CAN AND CANNOT BE RESTORED. Looking forward to helping you move this forward.

Hi there! You are trying to recover a Google Play game without original source files, and the real challenge is that decompiled APK code rarely restores a clean original project structure. I recently worked on an Android recovery case where we reconstructed a legacy game project from a published build, salvaging core logic, assets, and structure to rebuild it into a maintainable Android Studio project that could be safely extended. I will assess your APK or AAB, extract recoverable assets and logic, and rebuild a clean, editable Android Studio project structure. Where full recovery is not possible, I will recreate the architecture so the game can be updated and extended without breaking functionality. Check our work: https://www.freelancer.com/u/ayesha86664 Do you still have access to any old project files, even partial ones like Gradle configs or asset folders, or only the published Play Store build? I am ready to start — just say the word. Best Regards, Ayesha

We’ve reviewed your request, and to be upfrontfull recovery of clean, original source code from an APK/AAB is not realistically achievable. Decompiled code (via tools like JADX/apktool) is often obfuscated, incomplete, and not production ready, especially for games. However, a partial reconstruction + rebuild approach is definitely feasible within your budget ✅ What We Can Do 1️⃣ Extract APK/AAB and decompile code (Java/Kotlin level where possible) 2️⃣ Recover assets (images, audio, layouts, basic logic) 3️⃣ Reconstruct a working Android Studio project structure 4️⃣ Clean and refactor usable code portions 5️⃣ Rebuild core gameplay logic where needed 6️⃣ Deliver a compilable project + updated APK Approach 1️⃣ Analyze APK (check obfuscation, engine used – Unity, C++, native, etc.) 2️⃣ Extract resources and readable code 3️⃣ Identify reusable vs rebuild-required components 4️⃣ Recreate missing logic cleanly 5️⃣ Test and generate a working build Important Note • If the app was built with Unity/IL2CPP or heavy obfuscation, recovery will be limited → partial rebuild required • If standard Android (Java/Kotlin), recovery quality is better Why Us We bring 26+ years of experience in mobile development and debugging complex codebases. We’ll give you a clear assessment first, so you know exactly what can be recovered before proceeding. With regards, Harshvir Singh
