Desenvolvimento de Aplicativos Android Jobs

Preciso de um desenvolvedor capaz de criar um launcher SA-MP totalmente funcional para a plataforma Android. A ideia é permitir que um jogador instale o jogo e entre diretamente em nosso servidor sem lidar com passos manuais ou arquivos soltos. Funcionalidades indispensáveis: • Instalação de data automática — o APK deve baixar e posicionar todos os arquivos necessários na pasta correta. • Configuração personalizada — quero poder definir opções básicas (gráficos, idioma, diretório) de forma descomplicada. • IP fixo — o launcher deve conectar-se sempre ao nosso endereço de servidor predefinido, sem que o usuário precise editá-lo. • Designer b&...

I need a full-featured ride-sharing and pooling application built for both iOS and Android. The service is designed around shared trips only, so every screen should guide users toward combining routes rather than booking a private cab. For riders I must see live vehicle locations on an interactive map, smooth in-app payments (card, wallet, Apple Pay/Google Pay, etc.), and the chance to rate and review every completed journey. Drivers, on the other hand, should receive pooled-ride requests in real time, view the optimal pick-up order, navigate turn-by-turn, and track daily earnings from an in-app dashboard. A separate administrator panel will let me onboard drivers, monitor live trips, settle disputes, push notifications, and export ride analytics. Deliverables • One codebase (...

I want a full-featured social networking app built exclusively for Android. The core experience must allow users to create and edit profiles, exchange real-time messages, and browse an engaging content feed. Each of these three functions—profile creation, messaging, and feed consumption—has equal priority for the first release. You will handle everything needed to get a production-ready APK into Google Play: clean, well-documented Android code (Kotlin or Java), integration with a lightweight yet scalable backend of your choice, and a simple but modern UI that follows current Material Design guidelines. Authentication may start with email/password; social sign-in can follow in a later milestone. At hand-off I need: • Compilable source code with clear build instructions ...

I already have the complete Android source code and now need it visually overhauled. The task is a pure reskin: swap in my new logo, colors, icons, splash screen, and any other branding assets I supply. No deep feature rewrites are planned, but you may adjust XML layouts or minor Java / Kotlin snippets if that’s what it takes for the new design to fit cleanly. The project is built in Android Studio, so please be comfortable working with its latest stable release, Gradle, and typical asset pipelines. When you hand the work back, I expect: • Updated source code compiling without errors • A signed AAB/APK ready for Google Play submission • A brief changelog so I can track exactly what was touched If you can turn this around quickly while keeping the codebase tidy, ...

I need a straightforward Android productivity app focused purely on task management. The idea is to give users a clean, lightweight way to create, edit, and track their tasks on the go, without the clutter of calendars or note-taking modules. Core scope • Users must be able to add tasks, group or prioritize them, mark them complete, and search or filter quickly. • Data should persist locally and sync smoothly whenever the device is online. • A simple, modern UI that feels native to the latest Android versions is essential. I’m open to your suggestions on the specific paradigm—whether classic to-do lists, a kanban-style flow, or smart reminders—as long as it stays intuitive and fast. Please build with current Android Studio, and structure the code so...

I need a straightforward Android application that lets my customers send money to me by bank transfer. After signing up or logging in with the classic username-and-password flow, a user should be able to choose an amount, see (or pre-fill) my banking details, and push the payment through an integrated bank-transfer API. Security is critical, so the credential flow must be encrypted end-to-end and the transfer requests signed or otherwise verified to prevent tampering. A lightweight backend—REST or Firebase Cloud Functions is fine—can manage authentication, session tokens, and payment-status webhooks. Please deliver: • Full Android Studio project (Java or Kotlin) • Secure username/password authentication flow • Bank-transfer API integration with success/...

I’m looking for an experienced mobile developer to build a brand-new Android application from the ground up. The core idea is defined and the UI flow is sketched, but I need you to turn those concepts into a fully functioning app that runs smoothly on current Android versions. You will handle everything from setting up the project in Android Studio, choosing the right architecture pattern, coding cleanly in Kotlin or Java, and integrating any required APIs or services. I’ll provide wireframes, branding assets, and a detailed feature list once we start; your role is to translate that into a polished, deployable APK and tidy, well-commented source code. Please factor in essential quality steps such as unit testing, responsive layouts for phones and tablets, and Play Store readi...

I need a complete Android-based point-of-sale application that can be rebranded for different clients. All source code must be handed over so my team can swap logos, splash screens, and basic colour accents without touching the underlying logic. Core workflow requirements are straightforward: process walk-in sales smoothly, keep real-time inventory counts accurate, store essential customer details for repeat business, and generate clear on-screen and printable bills. The interface should feel classic and simple—think tidy screens, large touch targets, and minimal ornamentation—yet leave room for our logo and a primary brand colour. The build has to expose at least one clean way to push daily summaries to external accounting software (REST, webhook, or a small middleware modul...

I have built an app using lovable and want it now turned into an app on ios and android. It doesn't need to go in the app store, it can be published via test flight for iOS packaged as an apk for android as it only needs to be used by about 100 users. Ideally we will be able to update code in github and the apps will update on the devices, but i understand if this is not possible. App will need permissions for GPS, using the camera, saving photos to the local library and push notifications. Frontend: React 18 + TypeScript, built with Vite, styled with Tailwind CSS and shadcn/ui (Radix UI components) Backend: Supabase (hosted PostgreSQL database, authentication, file storage, and Edge Functions written in Deno/TypeScript) Routing: React Router v6 (single-page app) State Manage...

I need a clean, fully-working React Native development environment configured on my Windows machine so I can build and test for both Android and iOS. The goal is to finish with everything installed, verified, and documented so I can open a terminal, type one command, and see a Hello World app running on an Android emulator and an iOS build artifact generated through a reliable workflow. Please handle every step—from installing the correct Node version, JDK, Android Studio, and SDKs, to configuring environment variables, Gradle, and the React Native CLI. Because iOS compilation cannot run natively on Windows, I also need you to set up (or clearly guide me through) a workable solution such as Expo, EAS Build, or another cloud-based build service that lets me produce an iOS binary with...

I have a production mobile app built in Flutter that now needs two things at once: a smooth migration to React Native and a fully-featured AI layer. The current codebase performs “average”—solid, but far from the speed, maintainability, and user delight I want to reach. Here’s what I need from you: • First, review the existing Flutter project and outline a clean, low-risk migration path that keeps both iOS and Android parity. • While migrating, weave in a new AI layer that boosts user experience, adds meaningful functionality, and sharpens overall performance. I’m interested in API-based models that support chat-style assistance and data-driven recommendations; prompt design and runtime optimisation will be part of the job. • Once the Reac...

My Android Studio Java app is still targeting API 34 and I need it fully brought up to API 36. Alongside the version bump, I want the codebase tightened so it runs more efficiently and the overall look refreshed with a modern theme. Scope • Update Gradle files, libraries and any deprecated calls so the project compiles cleanly against API 36, including new permission or foreground-service requirements. • Profile and refactor hotspots to shave unnecessary CPU / memory use and eliminate obvious jank. • Re-skin the app with a contemporary Material-based theme—colours, typography and styles—while preserving existing layouts and behaviours. Upgrade all the dependencies used in the project. Acceptance The upgraded project must build without warnings on the l...

Android CameraX & API Integration (We have 80% of the code logic ready - No R&D needed) We are looking for an experienced Android Developer to build a technical prototype (MVP) focused on real-time image processing for a Huawei P10 device. IMPORTANT: We are not reinventing the wheel. We have already completed the research phase. We will provide you with: 1. The Official SDKs and Documentation needed for the project. 2. Reference Code (80% of the logic): We have identified specific open-source samples (Google Samples) that already handle the image capture and API request logic. Your job is NOT research.

I need a small Android proof-of-concept that launches the UIDAI FaceRD app via an explicit Intent, waits for the capture flow to finish, then receives the returned PID XML (biometric) data and renders it on-screen or writes it to logcat. Here is exactly what I expect: • An Android Studio project (Java or Kotlin) that targets any current SDK version compatible with FaceRD. • A signed, installable APK so I can test immediately. • On tap of a single button the app should:  1. Invoke with the correct action, extras and flags.  2. Handle the result in onActivityResult / ActivityResult API, extract the PID block, and show it clearly (raw XML is fine for the demo). Once I confirm the APK works, I will need the full, clean source code together with a sho...

I need a developer who can build a clean, stable Android application that lets users sit for fully-timed mock exams. The core of the project is the timer: each session must start, pause, resume, and submit automatically when time runs out, mirroring a real-world exam environment. For this first release I am only targeting Android, so please use a modern, well-supported tech stack (Kotlin or latest Java with Android Jetpack components). The UI should be lightweight and responsive, leaving room for future additions such as a question bank or analytics—but those extras are not in scope right now. Acceptance criteria • Home screen listing available mock tests • Start screen that clearly shows remaining time once the test begins • Automatic submission when the c...

I have a media-streaming application concept that must run natively on Samsung Tizen, LG webOS and Amazon Fire TV. I need someone who already lives inside these ecosystems: you understand the quirks of each emulator, you know where the documentation falls short, and you can architect a smooth, performant build rather than simply wrap a web page. What I need built • A fully functional streaming app that plays HLS/DASH video with adaptive bitrate, pause, seek and resume on all three platforms. • Platform-specific navigation that feels natural with each remote. • Store-ready packages: Tizen (.wgt), webOS (.ipk) and Fire TV (.apk). • Guidance on the underlying architecture—player abstraction layer, DRM hooks, storage strategy, performance profiling and memory...

I want a true Bluebook-style application that lets students sign up with email verification, log in securely, and sit for timed SAT Math sections. The same codebase should compile cleanly for iOS and Android phones as well as native Windows and Mac desktops so students can practise on any device they own. Core flow • Student creates an account, verifies via emailed link, and lands on a simple dashboard. • From there they can launch a full-length math section that mimics official SAT timing, auto-advances after each question, and locks once time expires. • At the end of the session the app instantly scores the attempt, shows the correct answers with explanations, and saves the record for later review. I will supply the question bank in CSV; the app just needs an import rout...

I have a working prototype built in Google AI Studio and I now need to take it from “demo” to a secure, production-ready release on both web and Android. First, I want every credential locked down. Both the API keys and the code itself must be protected: secrets moved to environment variables or Secret Manager, no keys exposed in the client bundle, and the repository cleaned of sensitive commits. A brief security checklist or automated scan that proves the hardening is complete will form part of the hand-off. Next comes a functionality sweep. I’m not sure whether anyone has formally reviewed the code, so plan to step through each user flow, patch breakages, and make sure the app genuinely meets Minimum Viable Product standards. User sign-in must switch to Google Authen...

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’m launching a worldwide singles fraternity—“Grupo Honest Singles”—designed to connect genuine people while giving special visibility and support to carefully selected owner-operator businesses. To make this vision accessible everywhere, the community needs to live both on the web and on mobile. The build covers a responsive website plus companion apps for iOS and Android that mirror the same core experience. Members should be able to create rich profiles, search and interact with one another, and discover businesses we endorse through a dedicated support section. Security and ease of entry matter, so the platform must allow account creation and sign-in through standard email/password as well as popular social logins. Key deliverables • Fully branded...

My dating app is already coded, tested, and running smoothly; now I need it live on both the iOS App Store and Google Play. I hold active developer accounts for each storefront, so provisioning profiles, certificates, and console access are ready for you from day one. Your task is strictly the release process: create production-ready builds, prepare store listings, configure in-app settings (privacy, screenshots, icons, descriptions, age rating, policies), submit for review, and shepherd the submission through until both stores show the app as publicly available. I will supply all design assets and copy; please feel free to suggest improvements if you see any compliance or optimisation issues. Deliverables I will sign off on • Signed, versioned IPA and AAB/APK bundles successfully...

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: ...

Project Goal Build a mobile-first digital payments app that allows users to send, store, convert, and spend crypto-backed USD with extreme simplicity, comparable to Zelle or Venmo — while crypto remains largely invisible to the user. Core Principle: “It should feel like a normal money app, powered by crypto in the background.” ⸻ Target Platforms • iOS • Android • Backend server • Admin dashboard (web) ⸻ Core MVP Functionality 1. User Authentication Required: • Phone number signup • SMS verification • Optional email backup • PIN or Face ID login • Secure session management System must: • Prevent duplicate accounts • Securely encrypt user credentials ⸻ 2. Automatic Wallet Creation Upon signup, the...

I have two signed Android APKs that share the same brand: a Chinese-language build that already handles user registration smoothly, and an English-language build that currently lacks this flow. My goal is to extract every user-management API call from the Chinese APK—endpoints, headers, payload structures, encryption or signing logic—and transplant that functionality into the English APK so both variants register users in exactly the same way. What I can provide: • The release APKs for both language versions • Valid test accounts and server access for live registration checks • Any additional assets the Chinese build relies on (native libraries, certificates, config files) What I need from you: • Decompile, inspect and document the Chinese APK (jadx, a...

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...

My Flutter app is finished and tested on my end; what’s left is to get it live on both Google Play and the Apple App Store. I already have active developer accounts for each platform and all listing assets—screenshots, icons, long/short descriptions—are prepared. I simply need someone who knows the submission pipelines inside-out to take the project across the finish line. Here’s what I’m looking for: • Build & sign the final release packages (AAB for Google Play, IPA for iOS) or validate the ones I provide. • Upload everything through Play Console and App Store Connect, filling in required metadata, privacy labels, content ratings and policy declarations. • Set up closed/internal testing: Google now mandates tester access prior to pu...

I own a licensed copy of the Dooo Movie Streaming Android source code and now need it running live on Google Play. The current project refuses to compile because of dependency issues and an outdated SDK. Here’s what I need from you: • Open the project in Android Studio, upgrade it to the latest stable SDK/Gradle versions, and cleanly resolve every dependency conflict so the APK builds without warnings. • Configure package name, signing key, Firebase/Ad-mob (if present in the code), and any other runtime settings the template requires. • Run a full device/emulator test to confirm login, streaming, search, and push-notification flows all work exactly as in the template demo. • Generate release AAB/APK and guide me through—or directly handle—th...

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...

I already own a full, unmodified copy of the WoWonder PHP script plus the matching Android Timeline App (a release from within the past year). All I need is an expert who has done this exact job before to turn that code into a Play-Store-ready build. Here is what has to happen: 1. Connect the Android source to my live WoWonder PHP site, including any custom server tweaks the API needs. 2. Reskin: swap in the new app name, splash screen, logo (I will supply the artwork) and adjust the primary colours so the interface matches the brand. 3. Change the package name to a unique identifier. 4. Produce a signed APK and an AAB bundle I can upload straight to Google Play. 5. Send brief notes on anything I must replicate if I update the code later. The server runs a customised configurati...
