Desarrollo de Aplicaciones para Android Jobs

Quiero lanzar una aplicación de chat sencilla que funcione tanto en iOS como en Android. El corazón del proyecto es la mensajería de texto en tiempo real, con la opción de que los usuarios envíen imágenes directamente dentro de cada conversación. Puntos clave del alcance: • Dos plataformas nativas o una sola base de código (multiplataforma es bienvenida) que compile para iOS y Android. • Pantallas básicas: registro / inicio de sesión, lista de chats, ventana de conversación, visualizador de imágenes. • Envío y recepción de mensajes de texto, con notificaciones push. • Carga y descarga de imágenes adjuntas, manteniendo compresión y vista previa. &b...

I maintain the “MediFind – Chemist App” on Google Play and have just received the policy notice that it must target the latest Android version ahead of the 31 Aug 2026 deadline. Right now the project still declares targetSdkVersion “API 36 or Higher”, yet Play Console is flagging the bundle because the compiled artefact is older. ****And Needs to add sound in one Place. Your task is to bring the entire codebase up to the current target API level accepted by Google Play, upgrade Gradle tooling, and resolve any breaking changes in code or third-party dependencies. The code is a standard Android Studio project (Java & a bit of Kotlin), published as an AAB; minSdkVersion must stay exactly as it is so existing users are not cut off. Key outcomes I need fro...

I need up to ten outdated product entries removed from the live catalogue in both the iOS and Android versions of my app. The items are no longer sold, so they must disappear from every user-facing screen, search index, and in-app notification feed without disturbing the rest of the inventory. You will have access to our Firebase-backed admin panel as well as the Git repositories for each platform. The task should include cleaning any linked images or metadata on the server to avoid orphaned assets and making a quick sanity check on the build after the change so the next App Store / Play Store release goes smoothly. Deliverables: • Removal of 1-10 specified listings from production databases • Verification that they no longer appear in either iOS or Android builds (simulator ...

My Android app has just been rejected by Google Play because it no longer targets the required API level, and I am also running into Google Cloud Storage failures in production. I need someone who can jump into the existing codebase, raise the targetSdkVersion to meet the latest Play Console requirements, resolve every compile or dependency conflict that appears, and then straighten out the cloud-storage layer so uploads and downloads work reliably again. The project will be complete when: • The app builds in Android Studio (Kotlin / Java) with the new API level and no deprecation or permission warnings that block release. • A release build is accepted by the Google Play Console without policy or API‐level errors. • All storage operations succeed against my current GC...

I’m planning a full-cycle mobile app build and I need an experienced developer or small team to take it from concept to launch. The core requirement is clear: this is a mobile app development project. I’m open to suggestions on whether the best route is native iOS, native Android, or a cross-platform framework—convince me with your preferred stack, past results, and the advantages you see. At this stage I’m still refining the exact feature set, so your ability to guide discovery, propose architecture, and flag potential pitfalls will be valuable. Expect to collaborate on wireframes, iterate through milestones, and hand over clean, well-documented source code along with basic test coverage. If you’re comfortable setting up an admin panel or analytics hooks, pl...

I need an Android-only application that can forecast the multiplier curve in 1xbet’s Crash game with convincing accuracy. Two core capabilities matter to me: • Real-time predictions that update before each round starts, giving the user a clear multiplier target or “safe cash-out” point. • A back-end layer that continuously absorbs past Crash rounds so the model can refine itself through historical data analysis. You are free to pick the stack—Kotlin, Java, or a cross-platform engine such as Flutter—so long as the final APK runs smoothly on current Android versions and the source code is clean, well-documented, and easy to extend. I will supply sample data streams; you handle everything else: data ingestion, model training, on-device inference,...

I'm looking to build an app similar to Astrosage, where users can connect with specialists via a calling feature. The call rate would be approximately 5 rupees per minute. Key functionalities include: - User registration and profile - Specialist directory - Payment processing The app should be developed for both iOS and Android platforms. Ideal Skills and Experience: - Proven experience in mobile app development for both iOS and Android - Strong background in integrating payment processing systems - Ability to design user-friendly registration and profile management features - Experience in creating comprehensive specialist directories Please include relevant past work in your application.

I need a seasoned Google Play Console expert to walk me through the entire process of launching my new game. I already have a personal Google account ready, but the developer account is not yet created, and none of the listing assets have been prepared. Here is what I’m after: • Create and fully verify the Google Play Developer account under my existing Google credentials, making sure all payment and tax profiles are correctly configured. • Prepare the Play Console for release: package signing, App Bundle upload, content rating, privacy-policy links, screenshots, feature graphic, and all mandatory store-listing text. • Submit the game for review, resolve any policy or compliance feedback from Google, and keep me updated until the title is live and searchable. A...

We currently have a Android App which has a interactive animation built in Java and Android XML, you can check what this animation looks like by clicking a topic in the app and then clicking any purple line. We want to add some panels on the homepage that displays each of the categories that we have and when these are panels are clicked we want these boxes to have a press animation. When the next page is loaded which has the topics for the chosen category that’s been selected we can split by latest etc. We may also want to change the page which lists all the topics into one topic per line and also animate the pressing of the topic in some way. I will share any further details required when we speak on chat. This may require you to add categories to our website database so that we ca...

I run a clothing retail shop and I’m ready to replace my paper spreadsheets with a single Android app that puts all of my numbers in one place. The cornerstone of the project is powerful analytics: I want to see trends, charts and drill-downs at a tap, so the data architecture needs to be built with future dashboards in mind. Core scope • Sales tracking – the app must record each sale on the spot and immediately feed two ready-made views: a daily sales report and product-wise sales breakdown. • Expense management – for now I only need to log and analyse utility bills, but the design should leave room to add inventory costs or salaries later without rewriting the database. • Simple form-based data entry – cashiers or I should be able to add a sa...

I’m creating “Crois moi c'est possible”, a brand-new social networking experience that will live exclusively on Android. The goal is to give users an intuitive space to connect, share photos and short videos, chat in real time, and receive instant push notifications—everything they expect from a modern community app, wrapped in a clean Material Design interface. You’ll take the lead on end-to-end Android development, so solid Kotlin or Java skills are essential. A cloud back-end (Firebase, Supabase, or a solution you recommend) will handle authentication, media storage, and real-time data. I’m keen on scalable architecture, readable code, and smooth UI/UX transitions; if you excel at Jetpack Compose, even better. Deliverables • Fully functi...

I’m planning an action-adventure title for Android where players can genuinely earn money by finishing missions or special challenges. The core loop is simple: explore, clear objectives, and receive a reward that can be cashed out or converted to vouchers—whatever technical route you suggest as most secure and compliant. Key gameplay idea A seamless, open-world map should invite exploration. Hidden paths, dynamic weather, and environmental puzzles will keep players busy between missions, but the primary incentive is that every completed quest credits their wallet. What I need from you • A fully playable Android build (Unity or Godot are fine—propose what suits the scope) • Source code with clean architecture so new levels and events can be slotted in lat...

I have already built a mobile app with the Kiro AI tool and now need a specialist to get it live on AWS, make sure every user flow works on Android, and iron out any bugs that appear along the way. Here is the flow I have in mind: • Set up the most suitable AWS hosting stack for a production-ready mobile backend (I am open to EC2, Elastic Beanstalk, Lambda or another AWS option you recommend). • Package and deploy the current Kiro AI build, including environment variables, storage and any required IAM roles. • Run thorough Functional testing on the Android version—covering login, navigation, API calls, offline handling, and push notifications. • Log defects, patch them, redeploy, and retest until the build is clean. Deliverables I will use for accep...

I need an Android app that sells my products and stays in perfect sync with a WordPress / WooCommerce website. The core flow is straightforward: shoppers should be able to browse, search, add to cart and check out—exactly as they would on a full-featured online store. Key capabilities I must have • Product reviews and star ratings displayed inside the app and written back to WooCommerce • Multiple payment gateways (at minimum PayPal and Stripe, with room to add more) • Push notifications for promotions, order updates and abandoned-cart reminders using Firebase or a comparable service How I picture the build coming together The app will pull catalogue data, inventory counts and order statuses in real time through the WooCommerce REST API, so anything I change on...

I’m preparing to launch a fintech mobile app that must run smoothly on both iOS and Android. I have the core product concept, wireframes, and a shortlist of third-party financial APIs, but I now need a full-stack developer who can carry the project from prototype right through to a store-ready release. The scope covers: • Building the cross-platform front-end with a clean, modern UI that mirrors the wireframes. • Designing and implementing a secure, scalable back-end (language and framework are flexible as long as they support rapid iteration, robust data protection, and easy deployment to cloud-based hosting). • Integrating payment rails, user KYC/AML flows, and real-time data feeds from the selected financial service providers. • Setting up an admin c...

Build a full-featured voice chat application that runs smoothly on Android and ships with the complete source code. Core features to implement • Phone-number verification as the only login method, followed by secure session handling. • User profiles that can be expanded later (start with photo, name, bio, interests). • Public chat rooms with high-quality, low-latency voice. • One-to-one private voice calls plus real-time text messaging. • Push notifications for invites, messages, follow requests, wallet events, and admin broadcasts. • In-app wallet able to hold balances, process top-ups, and trigger withdrawal requests; history must be visible to the user and editable from the back office. • Web-based admin panel to manage users, rooms, trans...

I need a complete chess platform built as both a responsive website and a native Android application. The core focus is real-time online multiplayer games, so smooth matchmaking, low-latency move synchronisation, and reliable game persistence are essential. Players will create accounts with a simple email-and-password flow; no social login or phone verification is required. During games, opponents should be able to communicate through text chat only—no voice or video. Please keep the chat lightweight, limited to the current match, yet protected against spam and abuse. To help me review your work easily, I would like separate deployable builds at each milestone: • Web front-end hosted on my server • Android APK ready for Play Store submission Both versions must...

The project involves building a native Android application from the ground up. I already clarified that the scope is specifically Mobile app development and, at this stage, I want to target Android only. Key needs • A clean, intuitive user interface that follows current Android design guidelines. • Robust, well-structured Kotlin or Java code (whichever you are most comfortable with) that is easy to maintain and extend. • All standard mobile essentials: responsive layouts for multiple screen sizes, offline handling where appropriate, and thoughtful permission management. • End-to-end support—planning, UI/UX, coding, testing, and a guided hand-off for Google Play deployment. Deliverables 1. Full Android Studio project with readable source code. 2. Sign...

I’m planning a clean, intuitive navigation app that runs natively on both iOS and Android. The core experience should be the familiar 2-D map interface with smooth pinch-zoom and tilt, focused on one key feature: reliable turn-by-turn directions. My priority is accuracy and speed. When a user selects a destination, the route should calculate quickly, announce upcoming turns clearly (voice + on-screen), and recalculate instantly if they deviate. I’m happy to leverage MapKit, Google Maps SDK, Mapbox, or another solid framework—whichever you feel will give the best licensing terms and performance on both platforms. While real-time traffic and fully offline map packs aren’t required for the first release, I’d like the architecture to leave room for those modul...

My latest build was rejected for “Unclear ads/offers: Ads or in-app purchase offers aren’t clearly different from your app’s content.” Google has already sent me detailed policy feedback with screenshots and exact paragraphs they believe I am violating. I need a specialist who can: • Analyse the Play Console report and the current APK/AAB to pinpoint every element Google flagged. • Modify the layouts, labels or flow so that banner, interstitial or native spots are unmistakably identified as ads/IAP and never mimic gameplay or menu assets. • Re-compile and test the updated build in Android Studio with the Google Mobile Ads SDK to be sure no new policy issues are introduced. • Prepare the final, signed AAB together with a short change log...

I am looking for an experienced mobile app developer or development team to build an MVP for a pet grooming services marketplace and booking platform for iOS and Android.

I’m looking for a results-oriented growth partner who can drive a steady, measurable increase in installations for my Android app. The app is already live on Google Play and tied directly to my website; what I need now is a well-planned mix of store optimisation and external promotion that translates into real user acquisition, not vanity metrics. Here’s what success looks like to me: a clear growth strategy, concise milestones, and transparent weekly reporting so we can double-down on what works and drop what doesn’t. I expect you to review the current Play-Store listing, refine keywords and visuals, set up and optimise Google Ads (or any other paid channel you recommend), and complement that with organic tactics—whether that’s social campaigns, influencers,...

I need a senior-level programmer to build a bootable Android virtual phone image that mirrors the experience of a physical device while running entirely inside a host system (similar in spirit to VMOS). Core requirements • The virtual environment must present itself as a standard Android handset. • Google Play Store has to work out of the box, and I must be able to install any additional APKs of my choice. Internet browsing is not critical; the focus is on app execution. • Instead of a live camera feed the system should expose a video carousel: a predefined folder of clips that loop automatically, appearing to any app as if they were coming from the camera. • The host environment must stay hidden so installed apps treat the image as genuine hardware—no...

I'm looking for an experienced mobile app developer to build TradeMate, a productivity app for tradespeople. The app aims to streamline job site operations for carpenters, welders, machinists, electricians, and builders. It should be available on both iOS and Android platforms.

I need our current link-based and QR-code donation experience reproduced directly on a Stripe Reader S710 or BBPOS WisePOS E. When a supporter approaches the terminal, the screen must show custom icons for the preset amounts £25, £50, £100 and £151, plus a “Custom” option that lets them key in any figure. After they tap their preferred icon, Apple Pay, Google Pay or contactless card payment should fire instantly, completing the charge through Stripe Terminal with the same back-end logic we already use for online links and QR codes. The scope includes: • Building the on-device interface with those four amount buttons and one user-defined field, matching our existing branding. • Wiring both link and QR code flows so the reader can present ei...

I need an Android-only application that works as a digital “health CV” for healthcare professionals. The core of the app is threefold: it must let users track key health metrics (vitals, lifestyle indicators, lab values), store and organise their personal medical records in a secure, searchable format, and schedule upcoming appointments with push reminders. All data has to live on the device first, with the option to sync to an encrypted cloud back-end for backup and multi-device access. The interface has to feel familiar to clinicians, so quick entry forms, barcode/QR code scanning for lab results, and tight permission controls are essential. A dashboard should surface trends over time with simple charts, and a separate “CV view” should export selected records and...

I’m building a real-time live-streaming social app that runs smoothly on both iOS and Android. Viewers must be able to watch a host go live, type comments that appear instantly, send virtual gifts that trigger on-screen animations, and play with fun AR filters or effects while broadcasting. All users should be able to create an account with whichever method suits them—classic email/password, one-tap social login, or phone number verification—then switch devices without losing data. A straightforward profile page, text chat outside the stream, push notifications for when favourite hosts go live, and a simple in-app wallet for gifts are also part of the plan. While I’m flexible on the tech stack, I do expect: • Mobile builds for iOS and Android, approved for A...

I need an Android-only matka application that lets players place bets, view live results, and manage their own profiles inside an intuitive interface. A built-in real-time chat room is essential so users can discuss draws and odds while they play. To keep the build straightforward, the core of the job is delivering a stable APK plus complete, well-commented source code. I will also need whatever lightweight backend or database structure you feel is best to store user accounts, betting records, and result history; feel free to suggest Firebase, Node, PHP-MySQL or any comparable stack you are comfortable with. Acceptance criteria: • Betting system: users choose markets, stake amounts, confirm wagers, and see history instantly. • Results display: winning numbers update without for...

I'm looking to develop a simple yet efficient Android application for printing lab certificates on card size using my printer. The application should be user-friendly and encompass essential features for seamless operation. Key Features: - Certificate Template Selection: The app should provide various templates for different types of certificates. - Database of Certificate Entries: A built-in database to keep track of all certificate entries, making it easy to print duplicates or track issued certificates. -Printing Preview: A feature that allows users to preview the print before actually printing, ensuring accuracy and saving resources. User Interaction: The application should be designed for manual data entry within the app. Users should be able to input data for the certificates ...

I need a single Android application that combines two core utilities: an efficient memory optimizer and an antivirus module. On the cleaning side, the app should intelligently free RAM, close unnecessary background processes, and provide clear before-and-after stats so users see how much memory was reclaimed. The process must be quick, unobtrusive, and light on battery. For safety, I want a built-in antivirus engine offering real-time scanning and automatic definition updates. As soon as a new file is downloaded, installed, or modified, it should be checked against the latest signatures and heuristics without noticeable lag. Updates to the virus database have to run silently in the background over Wi-Fi or mobile data, with fallback scheduling if the network is unavailable. I’d ...

I’m creating “Kings For Chess,” a web platform with a companion Android app where players can meet and play chess online in real time. The core of the project is an intuitive, lag-free chess board that works the same on desktop browsers and on the Android app, backed by a single user database so accounts stay in sync across both surfaces. Key functionality • Secure user registration and login (email, Google, or social sign-ins—whichever is quickest to implement while still safe). • Basic profile pages where players can upload an avatar, set a tagline, and see their game history. • Friend list so users can quickly challenge one another or track when friends are online. • Fast, server-validated move handling with illegal-move prevention, t...

I’m building a lively, cartoonish 3D endless-runner for Android where the hero sprints through Cityscape, Forest, and Desert tracks while hurling elemental attacks. A tap or swipe should let the player choose Water, Flame, Wind, or Thunder, then launch the chosen power straight down the current lane to clear oncoming enemies. Core gameplay • Continuous forward run with simple lane-switch controls. • Score counter that rises with distance and kills, and an adaptive difficulty curve that tightens spawn rates and speed over time. • Enemy types able to absorb damage and, if they reach the player, trigger a fail state with a quick restart. Monetisation & services AdMob is the ad network I need. Please wire in rewarded ads. All placements must respect Go...

I need a lightweight Android application that lets two users share one device’s screen in real time with crisp 1080p video and clear, low-latency audio. While the session is live, participants should also be able to exchange text messages in a small chat pane that can be shown or hidden without interrupting the stream. Core requirements • Runs smoothly on current Android versions, handling typical 30 fps desktop-class rendering without stutter • Uses efficient codecs (e.g., H.264 / AAC via WebRTC or a comparable stack) to keep bandwidth below 3 Mbps whenever possible • One-tap “Start session / Join session” workflow—no complicated log-ins or room creation needed • In-session text chat with message history retained only for that session (...

I’m ready to commission a mobile video editing app inspired by the core, non-AI editing experience of CapCut, built to run smoothly on both iOS and Android. The goal is to give users an intuitive editing workspace for importing, trimming, splitting, arranging and enhancing video clips and photos. Users should also be able to import photos or footage directly from supported social/media accounts where platform APIs permit it—import only, with no direct posting or publishing required. The app should focus on reliable, user-friendly editing tools rather than AI-powered functionality. AI features such as AI generation, AI effects, automatic editing, AI avatars, AI background removal, or similar AI capabilities are not required. Core Features * Video and photo import * Multi-cli...

Saya ingin merilis sebuah game petualangan single-player di Android yang memungkinkan pemain memperoleh uang atau hadiah nyata ketika mereka menuntaskan misi di dalam permainan. Genre sudah pasti petualangan; tidak ada kebutuhan untuk mode multiplayer, jadi semua alur, UI, dan logika cukup berfokus pada pengalaman satu orang pemain saja. Gambaran kerja: Saya butuh bantuan end-to-end—mulai dari merancang konsep level, membuat aset (atau memanfaatkan aset bebas royalti), sampai meng-compile APK siap rilis di Google Play. Sistem reward harus terintegrasi mulus dengan mekanisme pencapaian dalam game; apakah berbasis iklan, wallet koin in-game, atau model turn-in quest untuk voucher, saya terbuka didiskusikan selama tetap mematuhi kebijakan Play Store. Teknologi: Unity, Godot, atau en...

I want to recreate the Social App experience on both iOS and Android, keeping the focus tight on the two features my audience values most: rich user-generated reviews and an interactive map that lets them discover venues visually. For the initial release I do not need table-reservation mechanics; we can add that later once the core is rock-solid. The build has to be fully bilingual (English plus the ability to drop in additional language files easily), so please structure strings for effortless localisation. Users must be able to sign up and log in with either classic email+password or their preferred social account; a lightweight onboarding flow is essential. I’m open to your preferred stack—Swift/Kotlin, React Native, Flutter—all are fine as long as the final delivera...

I have a RecyclerView driven by a LinearLayoutManager. Card taps are currently picked up through an OnPress handler, and I already keep the underlying data in a ViewModel. The problem is simple: when a user opens a detail screen from any card and then presses the back button, the list always jumps back to the very top instead of revealing the card they originally tapped. I need the list to remember its exact scroll position so that returning feels seamless. You’re free to solve it however you feel is cleanest—saving and restoring the layout manager state, using the Navigation component’s back-stack handling, or any other proven method—as long as: • the previous scroll position is restored every time, • orientation changes don’t break the fi...

# Developer Needed – Flight Tracking Bot + Mobile App We are looking for an experienced developer to build a flight-tracking solution, initially focused on tracking aircraft associated with Formula 1 drivers, with the possibility of expanding the platform to other public figures and use cases in the future. ## Phase 1 – Twitter/X Flight Tracking Bot The first phase is to develop an automated Twitter/X bot that: * Tracks specific aircraft by registration/tail number. * Uses a reliable flight-tracking/data API. * Detects relevant events such as departures, arrivals, and potentially changes in destination/status. * Automatically publishes updates to a Twitter/X account. * Includes relevant flight information in a clean, consistent format. * Is designed so additional aircraft c...
