I can help you convert your APK into a proper Android App Bundle and also build an iOS version of your app. With 11+ years of experience in Android and iOS development, I have handled similar cases where only APK was available and the app needed to be rebuilt and published. Important Note: Since you only have the APK (no source code), I will first decompile the APK to understand the app structure, features, and flow. Based on that, the app will be properly rebuilt to generate a clean, maintainable project and create the iOS version. My Approach: • Decompile APK to analyze logic, UI, and resources • Recreate the Android project in Android Studio (Java/Kotlin) • Generate a signed AAB ready for Play Store submission • Ensure compliance with Google Play policies • Develop an iOS version with similar UI/UX and functionality • Perform testing and provide deployment guidance What I will deliver: • Fully rebuilt Android app + signed AAB • iOS app with matching features • Clean source code for future updates • Guidance for Play Store and App Store submission Timeline: 5–7 days (depending on complexity) I have strong experience in APK decompiling, reverse engineering, and cross-platform development, ensuring accurate and efficient delivery. Let’s discuss your APK and proceed.

As an accomplished mobile app developer with a solid understanding of iOS and Android platforms, and UI/UX replication skills, I'm your best fit for this project. Over my 7-year professional journey, I've not only developed standalone apps from scratch but also performed tasks similar to yours. I have reverse engineered APKs and rebuilt lost projects, something I believe is crucial for your APK file without source code situation. This will ensure you obtain an organized and streamlined Android App Bundle (.AAB) file ready for Google Play Store submission. Furthermore, my experience in iOS development will come in handy as I create the iOS version of your application. I am aware of the meticulous scrutiny the Google Play Store has for submission and make it my priority to ensure the app complies with all their policies and requirements. As shown in my diverse portfolio, I've worked proficiently using technologies like Java, Kotlin, Android Studio (for Android development), Xcode (for iOS Development), along with the ability to get things done within timelines - a week in this case for delivery. On top of that, given my experience as a teacher, you can be sure that I'll provide you solid documentation to understand the changes made. Choose me!

Dear Client, I have read your requirements carefully, and I understand you need to turn an existing Android APK into a proper Play Store-ready .AAB and also create an iOS version with similar functionality. I have worked on similar mobile app migration, rebuild, store-readiness, and cross-platform replication tasks before. Since you currently only have the APK, the first step is to inspect it and confirm whether a full rebuild is required. In most real cases, if source code is unavailable, the correct approach is to recreate the project structure, reproduce the app behavior/UI, generate a signed .AAB, and then build the iOS version cleanly from that recovered/rebuilt logic. I can also help check Play Store requirements, basic testing, and submission readiness. I’m comfortable with Android Studio, Java/Kotlin, app analysis, UI replication, iOS development, and deployment guidance. If you own the app and the rights to rebuild it, I can help you move this forward in a practical way without wasting time. I’m new on Freelancer, but I bring rich experience and would love for this project to become my first approved project on the platform. budget:1000 INR/hr. timeline: within 3-4 days I would be happy to work with you on this project.

Hello, As I am an Android developer, I can convert your APK into an Android App Bundle in 1 day for $80. I understand the main pain point here is getting a clean AAB build that is accepted by Google Play without breaking signing, package config, native libraries, or app behavior. I have worked on Android apps in Java, Flutter, JNI-integrated projects, Play Store releases, and performance/stability fixes, so this kind of packaging and build adjustment is familiar work for me. I would first review the current APK/build source setup, restore or adjust the Gradle configuration, check keystore/signing, app manifest, ABI splits, and dependency compatibility, then generate a proper release AAB. If needed, I can also verify bundle output for Play Console readiness and fix versioning or bundle-related errors before delivery. I will keep it straightforward and deliver the working AAB fast. Thank you.

Hi, I can help with this, but I want to be direct from the start: if you only have the APK and no source code, then in most cases the safest and most reliable path is a **full rebuild** of the Android project, then creation of the iOS version from that rebuilt logic/UI. That gives you something maintainable, Play Store–ready, and usable for future updates instead of a fragile workaround. I can handle: rebuilding the Android project from the APK behavior/UI, generating a signed **.AAB** for Google Play, checking Play Store compliance, and building an iOS version with the same core flow and look. What matters most here is making sure the final app is not just publishable once, but something you actually control going forward. If this is your app and you have the rights/assets, I can review the APK first and quickly confirm what can be matched exactly, what needs rebuilding, and the fastest path for a 1-week delivery window. Send me the APK and I’ll tell you immediately whether the rebuild scope is light, medium, or full. Best regards. Ankit.

Hi there, I’ve handled similar cases before, and I want to be upfront since you only have the APK, a full rebuild is required. Converting APK directly to a proper, maintainable project and generating a clean .AAB isn’t reliable for production apps. My approach: * Analyze APK (UI flow, APIs, features) * Recreate Android app in Android Studio (Kotlin preferred) with clean structure * Generate signed .AAB compliant with Play Store policies * Replicate UI/UX closely with improvements where needed * Build iOS version (Flutter or React Native recommended for speed within timeline) I’ll also ensure: * Proper app signing & Play Store readiness * Basic testing and deployment guidance * Clean, reusable source code for future updates I have experience rebuilding apps from APK references and delivering cross-platform versions with consistent functionality. Availability: Immediate Cost: Can be fixed after reviewing APK size/features (happy to keep it within a reasonable range) Happy to review your APK and give a precise estimate. Best regards, Shuvadeep
