I need a full-featured utility app built for the latest Android releases. The core requirements are a modern, Material-inspired UI, social-media-based login, responsive performance on both mid-range and flagship devices, and impeccably organised, well-commented source code that I can review and extend later. Here’s what has to be in place: • A clean Android Studio project written in Kotlin (Java modules are fine if you have a strong reason). • Social media authentication implemented with the official SDKs (Google and Facebook at minimum). • Smooth navigation and state handling using Jetpack libraries; the app must remain stable through configuration changes. • Compact APK/AAB, ProGuard or R8 configured. • Clear separation of layers (e.g., MVVM with Hilt or your proven architecture). • All strings and dimensions externalised so I can localise easily. • Publishing readiness: signed release build, Play Console–compatible assets, plus a brief walkthrough so I can push the first release myself. Deliverables: 1. Production-ready APK/AAB and full Git repository with readable commit history. 2. One-page build & deploy guide. 3. Up to two rounds of bug-fix revisions post-handover. If you already have libraries or boilerplate that speed things up, that’s great—just keep licensing clean and add the notices where required.

Hi, I’ve worked on similar Android application projects where the focus was building scalable, maintainable apps with clean architecture and reliable user experiences. I understand that this utility app needs more than just functionality; it requires a strong foundation that can be reviewed, extended, and maintained easily. A common challenge is balancing modern UI, authentication, performance, and code organization across different Android devices. My approach is to use Kotlin with a structured architecture like MVVM, implement official authentication SDKs, optimize builds, and ensure smooth state handling with Jetpack components. I will deliver a production ready Android Studio project, clean source code with documentation, social login integration, optimized APK/AAB builds, deployment guidance, and complete handover through Git with post launch bug support.

Hi, I understand you need a clean Kotlin-based Android app with solid architecture, social auth, and deployment readiness. I’ve built a similar utility app using MVVM and Hilt where we kept the APK compact and the codebase easy to extend, though we had to spend extra time tuning ProGuard rules. I’d use Jetpack Compose for the UI because it keeps the layout responsive and maintainable while avoiding XML inflation headaches. The biggest win will come from strict layer separation so future changes don’t ripple through the whole project. I’ll keep the Git history clean and only touch what’s necessary, testing changes in a staging build before you see them. That way you can safely extend the app without unexpected regressions. The goal is a stable foundation you can hand off without digging through spaghetti code. Happy to jump straight into the existing setup if it matches your vision. I can start right now. Thanks, Denis.

Hello, hope you are doing well. Facebook Login is worth deciding before anything else, because Meta now requires a completed App Review and a Business Verification before it works outside the developer account, and that approval sits with Meta rather than with us. It typically takes a few days but has no guaranteed window, so I'd start that process on day 1. Google Sign-In through Credential Manager has no such gate, which is why I'd wire it first and treat Facebook as a parallel track rather than a blocker. Architecture-wise, MVVM with Hilt, Compose for the UI, and Navigation with a single activity. State survives configuration changes when it lives in the ViewModel with SavedStateHandle for anything that has to outlive process death, which is the part that usually gets missed and shows up as a crash when the system reclaims memory in the background. For R8, the thing that catches people is that shrinking runs fine in debug and then strips reflection-based models in release, so the app builds and crashes on first API response. Keep rules written for the auth SDKs and any serialised classes, tested against the actual release build rather than assumed. Strings and dimens externalised from the start, Git with readable commits, one-page build and deploy guide, and 2 rounds of bug fixes after handover. A few questions. What does the utility app actually do, since the brief covers the shell but not the function? Is there a design or should I follow Material 3 defaults? Do you have a Meta developer account with a verified business already? And is there a backend or API it talks to? Have a nice day

First thing I'll do is set up the MVVM architecture with Hilt dependency injection and Jetpack Navigation so the foundation is solid before adding any feature layers. That way every screen survives configuration changes without hacky workarounds. I'll deliver the Kotlin project with Google and Facebook sign-in via their official SDKs, R8 shrinking configured for a compact AAB, and all strings/dimens externalised for easy localisation. You'll get the full Git repo, signed release build with Play Console assets, and the one-page deploy guide. One thing worth planning early: Facebook's login SDK has been pushing toward their Limited Login mode on newer API levels, which changes the token flow. I'll make sure the integration accounts for that so it doesn't break on review. Best regards, Shayan

Treat the bid amount and timeline above as rough ballpark figures for now. We'll firm them up once we've had a quick chat about scope. You're looking for a clean, well-structured Android app built on modern Kotlin with social login, Jetpack components, and code that you can actually pick up and extend yourself after handover. Not just something that runs, but something that's readable and maintainable. That's a pretty specific ask, and we've built enough of these to know the difference between code that looks good in a demo and code that holds up when someone else opens the project months later. Here's how we'd approach this: - Architecture: MVVM with Hilt for dependency injection, ViewModel and StateFlow for state management so the app survives rotation and process death cleanly. Layers stay separate from the start, not as an afterthought. - Auth: Google Sign-In and Facebook Login via their official SDKs, token handling done properly so sessions don't break on edge cases. Easy to add more providers later if needed. - Navigation and UI: Jetpack Navigation Component for a single-activity setup, Material 3 components throughout. All strings and dimensions in XML resources so localisation is just a file swap. - Build config: R8 minification and shrinking enabled, ProGuard rules tuned to avoid stripping anything it shouldn't. Signed release AAB ready for Play Console, with the keystore setup documented. - Handover: Full Git history with readable commits, a one-page build and deploy guide so you can push the first release yourself without needing us on a call. After a short scope chat we'll put together a written proposal covering deliverables, timeline and a firm price. Want to jump on a quick call this week to walk through it? Best, 96 Studio

Hi. To build this utility Android app, I’d set up a clean Kotlin project in Android Studio with a Material 3 UI, Jetpack Navigation, ViewModel, LiveData/StateFlow, and Hilt for a stable MVVM structure. I’ll integrate Google and Facebook sign-in through the official SDKs, then harden lifecycle handling so the app stays smooth across rotations and background restores. I’ll keep the APK/AAB lean with R8/ProGuard, externalize strings and dimensions for easy localization, and organize the code so you can extend it without rewriting core layers. As a Senior Android Developer, I have mastered Kotlin, Jetpack, Hilt, MVVM, Firebase/Auth SDKs, and production release workflows, and have strong experience in modern Android app builds, authentication flows, and publishing-ready packaging. I also keep repositories clean with readable commits and add the licensing notices needed for any reusable boilerplate or libraries. I am sure I can deliver high-quality results within 10 days. Let’s get in touch and discuss more. Thanks.
