I urgently need a seasoned Android engineer to take a brand-new idea from concept through to a fully working application. The exact feature set is still open for discussion, but whatever we build must run smoothly on both the latest devices and older phones and tablets without breaking UI or functionality. You will handle architecture, coding, testing, and deployment to Google Play, providing me with the full source code and a signed APK at each milestone so I can track progress. Expect to optimise for performance, follow modern Material guidelines, and implement solid backward-compatibility strategies—whether that means leveraging AndroidX, shrinking the APK with ProGuard/R8, or tailoring layouts with resource qualifiers. Clear, well-commented Kotlin or Java, Git-based version...

I am looking for a developer who can turn my idea for an Android-only social networking app into a polished, launch-ready product. The core experience should let users register quickly, build a profile, connect with others, share posts (text, photo, or video), react or comment, and chat in real time. A clean Material design, smooth performance on recent Android versions, and push notifications are essential. I plan to monetise later, so the codebase needs to be structured for easy integration of ads or in-app purchases. If you are comfortable working natively in Kotlin or Java and have handled cloud back ends such as Firebase, Supabase, or a comparable stack, your expertise is exactly what I need. Security best practices, scalable database design, and simple analytics hooks all matter to ...

I want to launch a non-custodial crypto wallet that covers the essentials from day one. Users must be able to send and receive coins or tokens, browse a complete transaction history, and restore access at any time through a secure backup flow (seed phrase or encrypted file). The first release targets Android and a browser-based version. Feel free to use Kotlin, Flutter, React Native, or similar for mobile, and React/ (or comparable) for the web client, so long as the codebase is clean and well-documented. Security should follow a solid “standard” approach: client-side key generation, AES-256 encrypted private keys, optional PIN/biometric unlock, HTTPS everywhere, and no server-side custody. Compliance with common audits or libraries (e.g., WalletConnect, ) is welcome but not...

I’m building a full-stack, fully secure money-exchange platform that spans Android, iOS, and a responsive website. The public landing screen must fetch and display up-to-the-second buy/sell rates even for guests, then invite them to sign in. Authentication will rely on Google Authenticator one-time codes; every sensitive endpoint must be locked behind this 2-factor flow. Once inside, customers need a clean dashboard where they can: • place buy orders • place sell orders • review a complete, filterable transaction history Behind the scenes I’ll need an admin console that lets me adjust spreads manually or, at the flip of a switch, pull live forex data from an API (feel free to recommend the most cost-effective feed). All price changes should propagate ...

I need an Android-only time management app whose core purpose is to keep users on schedule through smart notifications and reminders. The flow is simple: a user sets a task, defines a deadline or ideal start time, and the app nudges them at just the right moments. You are free to choose the framework (native Kotlin/Java or a cross-platform option that still compiles cleanly for Android) as long as the final build is stable, responsive, and Play-Store-ready. I’ll want both an installable APK and full, well-commented source so I can iterate later—potentially adding task scheduling or full time-tracking modules down the road. Key expectations • Clean, modern UI that feels intuitive on current Android versions • Reliable foreground and background notification ha...

I want a clean, lightweight Android application that my field sales team can open, log in with their company email and password, and capture secondary-sales orders on the spot. Two roles matter to me: • Salesman – enters demand, adjusts MRP-based discounts, and submits the order. • Manager – reviews or edits what the salesman submitted and can pull quick reports. The core flow is simple: after login the salesman selects the customer, adds products with quantities, sees the auto-calculated total, applies any discount by percentage or value, and taps “Generate Order”. The app must immediately create a branded PDF containing all line items, MRP, discounts, net values, date/time, and the salesman’s details. That PDF should save locally and be shareab...

I’m ready to turn my idea into a fully-functional Android application and need a developer who can guide the process from concept to Google Play release. At this stage I have the core concept and a handful of rough sketches; what I need now is help refining the user flow, designing an intuitive interface, building the backend logic, and packaging everything into a clean, well-tested APK. You’ll be working exclusively for the Android platform, so familiarity with current SDK versions, Kotlin or Java, Android Studio, and the play-store submission process is essential. If you can also advise on best-practice architecture (MVVM, Clean Architecture, Jetpack components) and integrate common services such as Firebase or in-app billing, that’s a plus. Please let me know: ...

I run a small personal-training gym and need a no-nonsense mobile app, published on both iOS and Android, that lets our members book one-on-one sessions with ease. The only core feature is personal-training booking, and after any slot is reserved the app must issue a session reminder. Members will create an account and log in before they can schedule, so a simple, secure registration flow is essential. Most of our clients are 60 + years old, so the interface has to be crystal-clear: large, high-contrast buttons, uncluttered screens, and navigation that never leaves them wondering what to tap next. Four or five screens total should cover it—welcome/login, calendar, confirmation, and settings—nothing more. I’m happy for you to work in Flutter, React Native, Kotlin Multipl...

I want to ship a lean Android + iOS application that can 1) establish a Bluetooth Low Energy link to my peripheral and move data back and forth, and 2) instantly push out a user-defined BLE packet the moment the phone detects an incoming call. The BLE work is classic data-transfer: discover the device, pair, subscribe to characteristics, then read/write packets on demand. Stability in the background is critical; the link must stay alive (or reconnect quickly) when the screen is off. When a call arrives the app should listen to the system broadcast (Android) or CallKit/VoIP push workaround (iOS), pull the string the user previously defined, and write it over the existing BLE connection without visible delay. Please send a concise, detailed project proposal outlining: • your ...

I’m ready to commission an Android-only audiobook application and need an experienced mobile developer to take it from concept to Google Play release. At its heart, the app must stream and locally cache audiobooks, let listeners drop unlimited bookmarks while they listen, and handle one-tap downloads for fully offline playback. Monetisation is essential: new titles will be sold individually, so please wire the catalogue to Google Play Billing for in-app purchases. Authentication will be straightforward email-and-password login—either a lightweight back-end you spin up or a Firebase Auth integration works for me so long as it’s secure and quick for the user. Core flow I have in mind • Launch ➜ user signs up or logs in • Library screen lists available au...

I want to bring a brand-new social networking idea to life on Android. The concept, user flows, and core screens are already sketched; now I need a developer who can turn them into a polished, production-ready app. Here’s the outline of what I’m after: • Full Android build in Kotlin (Java is acceptable if you have strong reasons). • Standard social features—secure sign-up/login, user profiles with photos, a simple post feed, likes/comments, and real-time chat or messaging. • Cloud-based back-end: I’m leaning toward Firebase for authentication, Firestore/Realtime Database, and push notifications, but I’m open to alternatives if you can justify them. • Clean architecture, modular code, and clear naming so another dev can jump in later if nee...

I’m ready to move forward with a project that pairs a full-featured Android app with a matching website. The core requirement both share is secure, reliable user authentication—think sign-up, login, password reset, and the usual account-management flows. Everything else about the product’s purpose, design language, and long-term roadmap is still flexible, so I’d like to refine those details together once you’re on board. I don’t have a fixed technology stack in mind; whether you prefer Kotlin in Android Studio, Flutter, React Native, or another modern framework on the mobile side—and Django, Laravel, Node.js, or something cloud-native on the web side—I’m open to your recommendations. What matters most is clean architecture, maintainabl...

Hi I will share the details with the shortlisted candidates. thanks

I need a very small Android application whose only job is to launch and immediately play a single MP4 video in full-screen. As soon as the user taps the app icon, the video should start on its own—no play, pause, seek bar, or any other controls visible. After the video finishes, the app can simply close or loop; I’m open to whichever is quickest to implement. The MP4 file will be provided. Please package it inside the APK, so the app works offline with no additional downloads. Android Studio, Kotlin or Java, and the built-in VideoView or ExoPlayer are all fine as long as start-to-finish playback is seamless on Android 8.0 and above. Deliverables: • Signed release APK for testing • Complete source code project that compiles in the latest stable Android Studio &bu...

I need an Android social-networking app built from scratch. The core idea is a clean, modern platform where users can register, create profiles, add or follow friends, share text-photo-video posts in a scrolling feed, chat in real time, and receive push notifications. A lightweight admin panel for content moderation is also required. Please deliver: • Full Android Studio project (Kotlin preferred, Java acceptable) with well-commented source code • REST or Firebase backend setup, documented and ready for deployment • Brief UX prototype early in the process and a functional MVP roughly six weeks from kickoff • Clear installation guide and API documentation so I can extend or port it to iOS later Material Design guidelines should steer the UI. I’m happy to su...

I have an existing Android app that is stable but still very lean on features. The immediate goal is two-fold: first, roll out a new “upload” capability inside the app (users need to be able to select a file—primarily images or PDFs—from local storage and send it securely to our backend); second, compile, sign, and publish the updated build to the Google Play Console so the change is live for all users. The current stack is Kotlin with standard Android Jetpack libraries; the backend is ready and exposes a REST endpoint for the upload, so the mobile side only needs to handle file selection, progress indication, and a simple success/fail response. If you prefer Java that’s fine—as long as the final APK/AAB plays nicely with our existing codebase. Deliver...

I need an Android app that lets my field-marketing reps see their entire day laid out on Google Maps, record every turn they take, and automatically total the distance they cover. Each sales call is flagged as a Meeting Point marker so the team can tap it, log arrival and departure time, and have the visit counted in their daily report. Core flow • Reps start a “shift”, the app begins GPS tracking in the background and draws the live route on the map. • Every time they reach a preset Meeting Point, the app recognises the stop, time-stamps it, and asks for a quick note or photo. • When they end the shift, the app stores a summary: full polyline of the route, total distance travelled, list of visited Meeting Points, and idle time between stops. A simple d...

I’m ready to move quickly on a native Android app focused on trading. The core idea is to give users a clean, fast interface where they can monitor real-time market data, place trades, and review their portfolio on the go. Here’s what I need from you: • A production-ready Android application written in Kotlin (Java is acceptable if you have a strong case). • Secure user authentication and encrypted storage of sensitive data. • Real-time price feeds pulled from a well-documented REST or WebSocket API that I’ll provide. • Trade execution workflows (place, modify, cancel) with robust error handling. • Responsive UI that follows current Material Design guidelines and looks solid on phones and small tablets. • A concise README and c...

I need a clean, native Android application that works as a focused productivity tool centred solely on task management. The core flow is simple: users create tasks, edit them, mark them complete, and view an always-updated list of what still needs attention. Fast load times, smooth transitions and a clutter-free Material-compliant UI matter more to me than a long feature checklist. Key features and behaviours • Add, edit, archive and delete tasks locally (Room or Realm preferred, but I’m open if you can justify another lightweight on-device store). • Optional grouping or tag system so users can sort their list quickly. • Swipe or long-press gestures for common actions. • Due-date picker with basic notifications. Push is not required at launch; local ale...

I’m ready to turn a simple game concept into a playable Android prototype and need a mobile-game developer who can move quickly from idea to on-device build. Here’s what I need at this stage: • A runnable Android APK plus complete source files set up in a common engine or native Android Studio project—your choice, so long as it’s easy for me to open and extend. • One short, self-contained level that shows the core gameplay loop with placeholder art and sounds. • Basic UI flow: splash screen, main menu, in-game HUD, pause/restart, and end-of-level summary. • Clean, well-commented code structured for easy future expansion. • Smooth performance on recent mid-range Android phones. I’m flexible on tools—Unity, Unreal, Go...

I need a small, self-contained Android application that runs only on my phone—no cloud, no remote server. The goal is to catalogue dancer profiles so I can show, search, and share them quickly during auditions. Core workflow • Create a new profile with name, age, height, full measurements, and the city the dancer is based in. • Attach multiple photos to each profile (photos are the priority), with the option to add a video clip later. • Browse or instantly search by city; that is my main way of organising the list. • From any profile, tap a button to share it straight to WhatsApp or Instagram without exposing the rest of the database. • Keep everything offline in an on-device database (Room or SQLite is fine). A simple “Backup / Restore&rdquo...

I want to bring a very focused Android app to life: its single goal is to help people relax by letting them browse and play short, soothing sound effects. Think of rain drops, crackling fire, or soft wind—nothing fancy beyond an intuitive catalogue and crisp, uninterrupted playback. Here’s what I need built: an Android application (Kotlin or Java, your choice) whose core functionality is sound playing. The user opens the app, taps a tile or button representing a specific sound effect, and the audio starts instantly. They can pause, stop, or switch sounds without lag. No social networking, e-commerce, or bulky productivity suites—just a clean, lightweight relaxation tool. Deliverables • Complete Android Studio project with well-commented source code • Signe...

I need a focused Android application that lets listeners stream my podcast episodes instantly—no forced downloads, just smooth, background-friendly playback straight from the feed. Engagement features I must have • User comments and 5-star ratings on every episode • One-tap social media sharing through the native share sheet (Facebook, X/Twitter, Instagram, etc.) • Push notifications when new episodes or announcements go live Deliverables • Complete Android Studio project (Kotlin or Java) with clear, inline comments • Release-ready APK/AAB plus a debug build for testing • README explaining how to swap in the podcast feed URL, configure notifications, and modify social links Acceptance criteria: streaming works reliably on Android 8-14,...

I need a full trio of mobile applications—customer, restaurant, and delivery—to replicate the seamless food-ordering flow you see in Swiggy or Zomato. The entire solution has to ship for both iOS and Android from a single code-base or parallel native builds; the choice of Flutter, React Native, Kotlin/Swift, or another modern stack is up to you as long as performance and store compliance are rock-solid. Core requirements for the customer-facing app: • Restaurant search and discovery with location awareness • Real-time order tracking from placement to doorstep • Secure, multi-provider payment gateway integration (cards, UPI, wallets) The restaurant app should let partners accept or decline orders instantly, update preparation status, and manage item availabi...

I want to boost awareness of my brand, Sangat bangus, through a dedicated Android mobile app. The core idea is a clean, engaging application that tells our story, showcases key products, and makes it simple for users to share content or offers with their friends. Scope • Design a modern, on-brand UI that feels intuitive on the latest Android phones and tablets. • Build core screens: home, product highlights, brand story, promo/offer section, and a share-with-friends feature. • Integrate push notifications so I can alert users to new campaigns or events. • Add basic analytics (Firebase or similar) to track installs, sessions, and share actions. Deliverables • Production-ready APK plus source code (Kotlin or Java). • All design assets and fonts in edit...

I’m planning to launch a brand-new social networking experience focused exclusively on Android users and I need a skilled developer—or team—to turn the concept into a fully functioning app. Scope of work The job covers everything from initial architecture through Play Store release. You’ll be responsible for designing the UI/UX, building the front-end in Kotlin or Java, creating the back-end (Firebase, Supabase, or another cloud backend you’re comfortable with), and integrating standard social features such as real-time chat, user profiles, newsfeed, push notifications, and media uploads. Clean, well-documented code and a modular structure are essential so the project can scale or later be ported to iOS. Deliverables • Interactive high-fidelity mock...

I need a full-function Android social networking application built from the ground up. The core idea is simple: let users create accounts, build a profile, connect with others, and share content in real time. I’m looking for a clean, modern UI that takes advantage of native Android components, built with Kotlin or Java in Android Studio, and underpinned by a solid, scalable backend (Firebase, Supabase, or your preferred equivalent). Key goals • Smooth onboarding: email, phone, or third-party sign-in • Personal profiles with editable photo, bio, and basic stats • Post feed supporting text, images, and short video • Real-time likes, comments, and push notifications • In-app messaging or chat to keep conversations flowing • Lightweight admin dash...

AI Assistant Feature Project Description: We are developing an AI Assistant Android app that currently works fine when it’s in the foreground, but stops responding in the background We need an experienced Android and Java developer who can implement a background service or foreground notification-based system so that: The AI assistant continues to run even when other apps are open. It can receive and execute commands from notifications or voice input while running in the background. The app should maintain minimal battery usage and comply with Android’s background execution limits (Android 10+). Key Requirements: Strong experience with Android Services (Foreground Service, WorkManager, BroadcastReceiver, etc.) Java-based Android app expertise (Kotlin is a plus) ...

I need a clean, performant Android e-commerce app built from the ground up. The core of the project revolves around a smooth product catalogue experience that lets shoppers browse, search, and filter items without lag. A secure, fully integrated payment gateway must be in place so buyers can complete purchases inside the app rather than being bounced to a browser. Shoppers should also be able to leave ratings and text reviews, both to boost trust and to help with product discovery. Sign-in will rely on social media credentials only—no traditional email/password flow. If you prefer Firebase Authentication, Facebook/Google SDKs, or another reliable SSO option, that works as long as setup is straightforward for end users and easy for me to manage. Because I will eventually submit the ...

I’m ready to bring my online store to Android and need a talented developer who can translate a straightforward e-commerce concept into a smooth, modern mobile experience. Because I’m starting with Android only, the build should be fully native (Java / Kotlin) or cross-platform so long as the Android release is polished and Play-Store-ready. Scope • End-to-end development of the Android app—from clean architecture and intuitive UI right through to final deployment. • Core e-commerce flow: product browsing, cart, checkout, and secure payment processing. (If you have proven plug-ins or gateway SDKs you prefer, let me know; I’m flexible as long as PCI-compliant options are in place.) • Admin-friendly integration so I can add or update inventory wi...

I’m building a lightweight yet polished video player for Android that feels as snappy as MX Player. The essentials are straightforward: it must play local MP4, AVI, and MKV files flawlessly and let the viewer load and switch subtitles without hiccups. A clean, modern look matters to me, so please wire in theme customization (at minimum light and dark, with room for future accents). I’m not asking for streaming, gesture navigation, or custom button layouts right now—those can stay on the wish-list until the core experience is rock-solid. I’m fine with ExoPlayer, Media3, or a comparable native library as long as you keep the codebase modular (Kotlin preferred, Java acceptable) and target the latest stable SDK. Smooth seeking, orientation changes that don’t...

My web application is already live, backed by Supabase and managed through a GitHub repository. The next milestone is a fully native mobile experience—Swift for iOS and Kotlin (or Java) for Android—mirroring the core web-app workflow without compromising performance or security.

I’m planning to launch a simple yet solid music-streaming application that runs natively on both Android and iOS. The core focus is a clean audio player that fetches and streams tracks from my back-end, with social-media login (Google, Facebook, or Apple) as the only authentication option—no email/password flow needed. I’m flexible on the tech stack: if you favour Flutter, React Native, Kotlin Multiplatform, or native Swift + Kotlin, that’s fine as long as the end result feels fast, modern, and stable on each platform. UI/UX assets, API endpoints, and sample tracks will be provided. Deliverables • Fully functioning Android and iOS apps compiled from a single codebase or two native projects • Social-media sign-in wired up and returning a valid user toke...

I want to turn “Wirna Mendrofa” into a polished mobile application and need a developer who can handle the full software-development cycle—from architecture and UI all the way to store submission. The finished product should run smoothly on both iOS and Android; how you reach that goal (native Swift / Kotlin, React Native, Flutter, or another framework) is up to you, so long as performance and maintainability stay top-tier. To be considered, send me a detailed project proposal. Walk me through your suggested tech stack, development milestones, testing process, and maintenance plan, and include links to any similar apps you’ve built so I can see your past work in action. Clear, well-commented code in Git, regular testable builds, and comprehensive deployment notes ...

I’m ready to turn my idea into a fully-functional Android application and need a developer who can guide the process from concept to Google Play release. At this stage I have the core concept and a handful of rough sketches; what I need now is help refining the user flow, designing an intuitive interface, building the backend logic, and packaging everything into a clean, well-tested APK. You’ll be working exclusively for the Android platform, so familiarity with current SDK versions, Kotlin or Java, Android Studio, and the play-store submission process is essential. If you can also advise on best-practice architecture (MVVM, Clean Architecture, Jetpack components) and integrate common services such as Firebase or in-app billing, that’s a plus. Please let me know: ...

I need the pin-to-keep behaviour added to my existing Android text-clip list. A user should be able to touch-and-hold any text clip in the RecyclerView; that gesture toggles a “pinned” state. Pinned clips remain in the local Room/SQLite store indefinitely, while every unpinned clip should be purged exactly one hour after its creation time. I’m fine with the standard Android UI conventions—think long-press selection, a pin icon in the contextual action bar, and a small pinned indicator inside each row. No custom assets are required beyond the built-in Material icons. The current codebase is Kotlin, minSdk 24, using ViewModel + LiveData. Please stay within that stack. If you see a cleaner Jetpack-recommended way to schedule the one-hour expiry (WorkManager or AlarmM...

I want to launch an Android-only application that showcases property listings and layers in practical AI assistance to make the experience smarter for both managers and renters. At its core the app must let a property manager add, edit, and remove listings (images, price, availability, basic details). The AI component should work behind the scenes—think auto-tagging amenities from photos, suggesting competitive pricing ranges, or surfacing the most relevant homes to a tenant based on their previous in-app behaviour. I’m open to the exact technique you use (TensorFlow Lite, ML Kit, embedded models, or a lightweight cloud call), so long as it stays responsive on typical mid-range Android devices. No third-party property-management or CRM integrations are required; the app should...

The current production build of my app is intermittently crashing, and I need a clean, targeted code update to eliminate these functionality-related bugs without introducing new issues. The crashes appear after recent OS updates and seem tied to memory handling inside two core screens; logs point to null pointer exceptions in the data-binding layer. You’ll receive: • Full Git repository access (Android, Kotlin + a small legacy Java module) • Current crash logs from Firebase Crashlytics and Logcat • A short video that reproduces the issue on two devices What I need from you: 1. Diagnose the root cause of the crashes. 2. Refactor or patch the affected classes so the app runs reliably across Android 8-14. 3. Commit code in a separate branch with clear co...

• Top-up wallet and recurring subscription system that gates premium episodes and tracks balance in real-time. • Smooth audio streaming with background play; buffering and bitrate handling should feel invisible to the listener. (Offline downloads are optional for a later sprint, so build with that future toggle in mind.) Design & tech notes The UX should echo popular audio apps—clean mini-player, intuitive queue, dark/light mode if practical. I am comfortable with Kotlin or modern Java and would like well-structured, maintainable code. If you rely on a backend (Firebase, custom REST, etc.) outline the stack and provide clear API documentation so future content ingestion is straightforward. Deliverables 1. Source code and compiled APK ready for Play Store submission. 2...

I’m building a focused social-networking experience exclusively for Android. The first release centres on one core interaction: creating and managing friend connections. Users must be able to discover new people, send and accept requests, organise their contacts, and browse basic profiles in a fluid, Material-design interface. Messaging and photo sharing are out of scope for now; the architecture, however, should keep future modules in mind. You’ll receive my wireframes and brand assets on day one. From there I need a clean Android Studio project, preferably in Kotlin, targeting API 26+. Please follow standard MVVM patterns, use Jetpack components where they add value, and keep third-party libraries lightweight and well-documented. Deliverables • Complete, well-comment...

I need a reliable Android developer to jump into my existing project and resolve a few lingering bugs. The code-base is stable overall, but a handful of issues are affecting the user experience and I’d like them cleaned up quickly so I can push the next release to Google Play. You will receive: • The current Android Studio project (Kotlin) • A concise list of the reproducible bugs with steps, expected vs. actual behaviour, and device logs where available I expect: • Clean, well-commented fixes that slot neatly into the existing architecture • No regressions elsewhere in the app—please test on at least two API levels • A pull request or zipped project, plus a signed APK so I can verify on real devices If this sounds straightforward for...
