Desarrollo de Aplicaciones para Android Jobs

I have a batch of Android tablets that refuse to complete their normal software update because I can no longer sign in to start the process. I need a freelancer who can walk me through—or remotely carry out—a full software update so each device is running the latest version it supports and all security patches are applied. The work will be finished once every tablet can: • sign in without errors • download and install the current official system update • reboot and operate normally afterward If you have proven experience recovering locked-out devices and pushing OS or firmware updates, I’m ready to get started right away.

The mobile app is already well underway, but I now need a seasoned developer to take it across the finish line for both iOS and Android and, at the same time, give the iPad layout the attention it deserves. Here’s where things stand and what I expect next: – Core functionality is largely in place, yet a handful of screens and background services still need wiring up and thorough testing on iPhone, iPad, and the most common Android devices. – The iPad build runs, but the interface is still iPhone-sized; I’d like a clean, adaptive layout that feels native in both portrait and landscape modes, with smooth split-screen behaviour. – Once the last pieces are coded, I’ll need you to run a full QA pass, resolve any crashes or UI glitches, and prepare c...

I want to turn the quirky idea of a “Chicken Road Prediction Bot” into a fully working Android app. The concept is simple: feed the app either live video or pre-recorded movement data of chickens near a roadway and have it predict if, when, and where a bird will step onto the road. The platform is strictly mobile and Android is the only operating system I need supported. Here’s what I expect: • A lightweight Android application (Kotlin or Java) with a clean UI that shows a camera preview or data feed and overlays the real-time prediction. • An on-device model—TensorFlow Lite, PyTorch Mobile, or a comparable framework—that can run offline and outputs a confidence score plus an ETA for the crossing. • A simple stats panel logging every pr...

I need to modify my existing Android app by adding a new feature: a floating window to control the dice number. Ideal skills and experience: - Experience in Android app development - Proficiency in creating and integrating floating window features - Strong understanding of app modification and feature addition - UI/UX design skills would be a plus, to ensure the new feature is user-friendly Please ensure the new feature is seamlessly integrated and does not disrupt the current functionality of the app. Looking forward to your bids!

I need a mobile app developed for both iOS and Android platforms, designed to help users track their savings goals. The main feature should be goal tracking, but I also want the app to include: - Notifications/Reminders: To keep users on track with their savings. - Graphical Reports: Visual representations of their savings progress. - Integration with Bank Accounts: For automatic updates and a more seamless experience. Ideal skills and experience: - Experience in mobile app development for both iOS and Android. - Strong UI/UX design skills to create an intuitive and engaging user experience. - Familiarity with integrating bank APIs for real-time data updates. - Proficient in implementing notification systems within mobile applications. - Ability to create detailed and user-friendly graph...

I have an idea ready to move from concept to the hands of users on both iOS and Android. The scope covers everything from the first line of code to store submission, so I need a developer who can handle design, front-end and back-end work, testing, and deployment in one rapid cycle. Speed is critical—ASAP really does mean as soon as humanly possible—so you should already be comfortable with an accelerated workflow, quick iterations, and clear progress updates. You are free to pick the tool-set you trust most (Swift + Kotlin natively, or a framework such as Flutter or React Native) as long as the finished product feels fully native on each platform. Essential deliverables • Complete, well-structured source code • Builds ready for TestFlight and internal Android...

I want a single, fully-automated application that lets customers in multiple cities book our on-site services—painting, home cleaning, plumbing, and electrician work—while also letting them purchase industrial safety goods that ship from our main warehouse. The build must ship on iOS, Android, and the Web and recognise three clear user roles: Admin, Customer, and Gig Worker. Customers will browse services or products, lock in a slot or place an order, pay online, and receive an invoice generated automatically in Zoho Books. As soon as a job is confirmed it should flow to the nearest available Gig Worker, who will see it in real time, accept or reject, navigate to the address, update job stages, add photos, and close the task. Throughout the process the system must provide: ...

I need an app that sends messages to the user at species times. Also has some readings or videos to watch. Motivational, calming, sharable moments. Time zone matters. Scalable to a paid version

I need a lightweight Android application that keeps my customers instantly informed about their purchase progress. The core task is to build a stable push-notification system that fires whenever an order moves to a new status in our back-end. Each notification must be clear, timely, and triggered exactly once per status change so users never miss an update or receive duplicates. My API team will expose a simple REST endpoint returning the current order state; you can poll it or use webhooks—whichever gives the most reliable result on Android. Feel free to integrate Firebase Cloud Messaging if it speeds things up; I just need the service to scale and to handle basic fail-over scenarios. At this stage I am not asking for full real-time map tracking or a user-login module, but I would...

I want to create an Android application that works much like the Superfone IVR app, but tailored to my organisation’s customer-support workflow. The core goal is to make it effortless for callers to reach the right information or person without waiting on a human operator. Key functions I need built in: • Automatic IVR flow that greets callers and routes them through spoken menu options. • Branches that allow callers to:  – get answers to common questions,  – record and escalate complaints,  – request detailed information that will be sent to them by SMS or email. • An intuitive dashboard where I can update the menu prompts and review call analytics. • Secure cloud storage for recordings plus the ability to download ...

I need an Android application that allows people to join real-time voice chat rooms, exchange short voice messages, and build public or private groups around shared interests. Every user should have a rich profile (avatar, bio, follower count, etc.) that is visible inside and outside rooms. Access & security Sign-in must happen exclusively through Gmail-based email login, using Google OAuth so the flow stays familiar and frictionless. No phone or other social options are required at launch, though the architecture should leave room for them later. Core feature set • Live group voice chat rooms with push-to-talk and host-controlled mic permissions • One-to-one or one-to-many voice messages that can be played back inside the room or in direct chats • Persistent u...

I am looking for an experienced full-stack developer to build a simple MVP website for an Android device software-support business. I have a reference website for understanding the general workflow and type of platform I need. The developer should create a new, original website, including original code, UI implementation, branding and assets. Website Pages * Home * Services * Supported Brands * About * FAQ * Contact * Login * Registration Initial Supported Brands * Xiaomi * Vivo * Oppo User Dashboard After registration/login, users should be able to: * View available services * Select a brand * Select a device/model * Select a service * Submit a service request * See processing status * View request history * View request/result information * Contact support Demo Service Function ...

Android Device Service Demo APK – Xiaomi, Vivo & Oppo Description I am looking for an experienced Android developer to create a simple demo/testing APK for a mobile-device software-support business. The application will be used as a UI/workflow demonstration only. It must not perform real FRP bypass, security-lock removal, IMEI modification, or unauthorized device access. Main Requirements The APK should have a professional tool-style interface with: * Xiaomi * Vivo * Oppo * Device/service selection * Device model field * Service selection * Order/request button * Processing animation * Demo result/status * Success/failure status * Order/reference ID * Simple activity/history screen * About/support section Demo Workflow Example: Brand: Xiaomi Model: Redmi Note 13 Service...

I’m looking for a developer who can build a lean, production-ready Android shopping app that does one thing exceptionally well: move users from “Add to Cart” straight through a secure checkout and payment gateway. Scope • Native Android build (Java or Kotlin) that runs smoothly on the current OS versions. • Core screens: simple product view (fed by my existing API), cart summary, shipping details, payment screen, and order confirmation. • Integrated payment gateway—Stripe is preferred, but I’m open to your recommendation as long as it supports major cards and works worldwide. • Guest checkout only; no user sign-up or login flows. • Clear error handling, validation, and success/fail callbacks so I can track each order’s...

Saya membutuhkan bantuan untuk membuat sebuah aplikasi bisnis khusus untuk platform Android. Inti proyek ini adalah menghadirkan integrasi pembayaran yang andal dan aman langsung di dalam aplikasi sehingga pengguna dapat bertransaksi tanpa harus meninggalkan ekosistem Android. Lingkup kerja: • Merancang dan membangun aplikasi native Android (Java / Kotlin dipersilakan). • Menghubungkan aplikasi ke gateway pembayaran populer sesuai standar keamanan terbaru. • Menyiapkan antarmuka sederhana yang memandu pengguna dari katalog produk hingga proses checkout. • Menguji seluruh alur pembayaran, termasuk skenario kegagalan dan refund. • Menyediakan dokumentasi singkat dan panduan build agar tim saya dapat memelihara aplikasi ke depannya.

I need a complete Android application that lets both riders and drivers schedule rides ahead of time. The scheduling flow is the highest priority: a rider should be able to choose pickup, destination, date, and time; a nearby driver receives the request, can accept or decline, and both parties get confirmation inside the app. Although real-time tracking and payment integration are off the critical path for this first version, the codebase should be clean and modular so those features can be bolted on later—or even ported to iOS or Web without a full rewrite. Deliverables • Production-ready Android app (APK + Play Store-ready bundle) • Full Kotlin/Java source code in a Git repo with README setup instructions • Simple backend (Firebase, Supabase, or similar) handli...

I have a fully-built mobile app in FlutterFlow that I’m now ready to take native. Your job is to reproduce the entire experience in Swift for iOS and Java for Android, matching the original design pixel-for-pixel, duplicating every feature, and retaining the same smooth performance—or improving it where possible. The current build works, but being tied to FlutterFlow limits my control over custom code and optimisation. I’ll provide the existing FlutterFlow project, Figma screens, backend endpoints, and a brief test plan so you can see what “identical” really means. Key expectations • UI/Design fidelity: layouts, colours, typography, animations, and any custom widgets must look and feel exactly the same on both native platforms. • Features &...

Inwant a image cum catalog of my real estate inventory to share to potential buyers

We operate as a software house and are delivering this project for one of our clients. The project is an Android application built in Flutter, designed to improve and extend the functionality of popular ride-hailing applications. We have been developing this project over the past several months, and the client is interested in continuing its development in the future. For this reason, we are looking for an individual developer or a team with whom we can establish long-term cooperation. Unfortunately, we currently do not have access to the application's original source code repository. The previous development team involved in the project has closed its business, so at this stage we only have access to the latest APK file. Based on this APK, it will be necessary to recreate the appl...

I want a complete Android chess app that feels modern and social. The board and pieces should be fully 3-D, rendered smoothly on mid-range phones, with intuitive pinch-zoom and rotate gestures so matches feel immersive rather than flat. Core gameplay centres on real-time online multiplayer. Players must be able to start a quick match against anyone worldwide or create a private room and invite friends. While a game is running, a lightweight in-app chat window should sit beneath the board so opponents can talk without switching screens. Around the games, I need a simple community layer: • Persistent friend list so users can add, remove, and directly challenge contacts. • Elo-style ranking system with leaderboards that update automatically after each rated match. Google, Faceboo...

I need testers to opt in to the closed testing track for 2 Android apps on Google Play, so I can meet Google's requirement of 12 opted-in testers per app before applying for production access. What I need from you: Click the opt-in link I provide (one per app) Join the closed testing program via your Google account Install the app from the Play Store closed-test link Open the app once and keep it installed for at least a few days (Google tracks active opt-ins, not just clicks) Confirm back to me once done (screenshot is fine) Requirements: A real, active Google account (Gmail) An Android phone (or Android emulator) Willingness to do this for 2 separate apps Details: This is a one-time task, takes about 10–15 minutes total per app No app usage or feedback required — j...

I need an experienced Android developer who can help me root my Android device safely. Requirements: * Identify the correct rooting method for my exact device/model * Bootloader unlocking guidance * Install/patch the correct boot image using Magisk * Root access setup and verification * Explain every step clearly * Ensure the process does not unnecessarily brick or damage the device * Provide recovery/unroot instructions if required I will provide the exact phone model, Android version, and other device details.

I’m adding a free-trial membership to my Android mobile app and need an experienced developer to wire everything up smoothly. The core goal is simple: a new user installs the app, taps “Start Free Trial,” and immediately gains access to premium features for a limited period before deciding whether to subscribe long-term. Here’s what I already have: the app is live on Android, built with standard Kotlin and Jetpack components. What I need from you is the full trial workflow—front-end prompts, Google Play Billing Library integration, trial duration settings, and automated conversion or expiration logic. A lightweight, well-documented back-end hook (Firebase, Node or similar) that records each trial’s status would also be helpful so I can track uptake and ...

I’m putting together a light-hearted 2-D brawler for Android that must stay small and completely offline. Scope is intentionally tiny: one playable hero, three distinct villains and only three short stages. The move-set is equally compact—punch, kick and a slapstick shoe-throw—so there’s no need for complex combo systems or elaborate physics. Visually I want classic pixel art with bright, cartoon flair. Each level should be backed by a single fast-paced, energetic Hindi track that loops cleanly. Two uncomplicated power-ups will drop in-game: a health boost to refill the life bar and a speed boost for brief bursts of agility. Please keep the codebase lean and readable; no heavy online features or giant frameworks—just a tidy project I can open, compile an...

### Project: Android App Closed Testing – 12 Testers for 14 Days I have developed an Android board game called **“Bagh Chal – Tigers & Goats”**, which is currently in Google Play Console Closed Testing. Due to Google Play requirements for my developer account, I need **at least 12 testers to opt in and remain opted in to the closed test for a minimum of 14 days** before I can request production access. ### What I need I am looking for a freelancer/team who can provide **12+ genuine Android testers** for the complete testing period. Each tester should: * Have a working Android smartphone * Join the closed testing program using the provided Google Play testing link * Install the application from Google Play * Keep the app/test participation active for at lea...

I already have production-ready iOS (.ipa) and Android (.aab) builds, icons, and a style guide. What I need now is someone who can take those assets and carry the release the rest of the way—right through Apple’s and Google’s review queues—without me having to chase any last-minute details. Your responsibilities • Set up or tidy the App Store Connect and Google Play Console entries, linking the correct bundle IDs and package names. • Populate every field in the store listings—title, subtitle, long description, keywords, privacy labels, age rating, content rating questionnaire, and policy declarations. • Prepare and upload device-specific screenshots and promo graphics; you can compose simple mock-ups yourself or resize the artwork I suppl...

I need a straightforward Android-only application that lets me record the daily status of each customer order while I’m on the go. The core flow is simple: open the app, pick or type an Order ID, choose a status (for example Pending, Shipped, Delivered, Cancelled), add an optional note, then hit Save. I should be able to review and edit past entries just as easily. Because this will be used every day, the interface has to load fast, work smoothly on recent Android versions, and stay usable even when the device is temporarily offline—queued entries can sync once a connection returns. Feel free to recommend a light, reliable backend (SQLite, Firebase, or another option you trust); I’m flexible as long as the data is stored safely and can be exported later. Deliverables ...

I’m building an Android-only app that lets customers browse our services, lock in an available time slot, and leave a deposit before the appointment is confirmed. I will supply the full set of business rules that define working hours, blackout dates, staff skill levels, and any custom availability logic—your job is to translate those rules into a smooth, error-free booking flow. Key functions I expect from day one: • Real-time availability based on my rules, with instant reservation once the deposit goes through. • Google Calendar two-way sync so new bookings appear on our shared calendar and any changes we make there update the app. • Push and email reminders for both the customer and our in-house team, plus automatic handling of reschedules and cancellati...

I’m building an Android-only application that lets customers book our home-service offerings in three quick steps: pick a service, choose an available time slot, and secure it with a PayPal deposit. I’ll supply the detailed business rules that govern which technicians are available when, along with all exception logic. The core build needs to cover: • Real-time slot calculation based on the rules I provide • Secure PayPal deposit collection and confirmation • Two-way calendar sync (Google Calendar preferred) so my team’s schedules update automatically • Push and/or SMS reminders for both customers and staff • A straightforward cancellation flow that triggers our refund policy logic • A lightweight dashboard where the team can view,...

I’m building an Android-only e-commerce application and want to nail the browsing experience first. The core task is to create a smooth, responsive product-listing and search module. Shoppers must be able to explore the catalogue, type a query, and instantly refine results by ratings and reviews—you can treat that filter as mandatory. If you have a clean way to layer in other filters or even lightweight recommendations later I’m open to it, but for this milestone I only need: • Search bar with real-time suggestions • Ratings & reviews slider or toggle to narrow results • Pagination or lazy-load list so large inventories feel fast Please implement in Kotlin (Android Studio), follow modern MVVM or similar architecture, and keep the codebase rea...

I need a focused, field-ready Android application that lets our security personnel capture incidents the instant they occur. The flow is straightforward: officers open the app, complete a structured incident form, attach photos or short video clips straight from the device camera or gallery, and submit. As soon as a report is logged, real-time push notifications must alert relevant team members so nothing slips through the cracks. Because this will be used exclusively by trained security staff, the interface has to be fast, uncluttered, and usable with one hand—think large buttons, offline caching in spotty coverage areas, and a minimal number of taps to completion. Deliverables • Android Studio project (Kotlin or Java) with clean, well-commented code • Signed APK...

I want to give my Reiki Healing clients a simple, fully-featured Android experience they can download straight from Google Play. After a quick login, users must be able to: • book a treatment in an available time slot, • chat with me in real time, • pay instantly through UPI, • browse all Reiki Healing services, • check their profile and past sessions, • receive push notifications for reminders and promotions. On the back end I need a straightforward admin panel where I can set or block appointment slots, reply to chat messages, track payments, and push notifications or content updates. A lightweight marketing website that mirrors the app (service list, contact form, Play Store link) should be included so new visitors can learn about us befo...

I need a lightweight Android browser built around permanent Incognito mode, so no history, cookies, or cache are ever stored. The overall look should stay clean and clutter-free; think a single address/search bar, slim toolbar, and nothing that distracts from the page content. Although the interface must stay minimalist, I still want users to be able to tweak it—simple theme or accent-color switches, the ability to move or hide the toolbar, and a setting to choose the default search engine will be enough. Please build on standard Android WebView (Kotlin or Java in Android Studio) and keep the codebase well-commented. I will need: • Release-ready APK • Full source code with build instructions • A short README outlining how the incognito implementation works ...

Google has warned me that my Play Console account will be closed for inactivity. I did try to trigger some activity on the account, yet the closure notice remains. What matters most right now is pushing an update for the existing app so data, reports, and overall access stay intact. I need someone who can: • Analyse the current state of the Play Console account and the warning notice • Prepare a minimal but compliant APK/AAB build (even a small version-code bump is fine) in Android Studio or a similar tool • Guide me through signing it with my original keystore and uploading it for review • Confirm the submission shows as “active” in the dashboard and that the account warning is lifted Acceptance criteria: 1. An updated release is successfully publis...

I sell a range of services and products and now want a straightforward way to enlist referral partners. I need two linked Android apps—one for the partner and one for me as the admin. Partner app • Login must be by mobile number (OTP flow is fine). • After logging in, the partner sees a single form to capture the referral’s name, address, phone, and email. • The same screen should let the partner attach supporting documents (images or PDFs). • A small dashboard listing every referral the partner has submitted would be helpful so they can check status. Admin app • I should be able to view each partner’s submissions, open the attached files, and mark a referral as approved, rejected, or pending. • Basic search / filter by partner ...

I need a straightforward Android application that lets users access the app through a secure username-and-password login screen. At this stage I am focusing only on Android, so you can use Android Studio with Java or Kotlin—whichever you are most comfortable with. Core scope • Clean, intuitive login interface • Secure credential handling (local encryption or a backend such as Firebase/Auth0—open to your best-practice suggestion) • Well-structured project files and clear comments so I can maintain the code later Optional next steps (not in this job but good to keep in mind) could include subscription flows or cloud integration, so please architect the code with scalability in mind. When you hand over the APK and full source code, I will test the build ...

I need an Android application that authenticates against a Pepperstone cTrader account through the official cTrader Open API using the Implicit Grant flow. After sign-in, the user must be able to: • securely fetch and display current account balances, open positions, and full account history • place, modify, and close trades from both demo and live accounts Push notifications are not required, so everything should happen in-app. Please follow cTrader’s recommended OAuth security practices, store tokens safely, and make sure the same codebase can be switched between demo and live environments with a simple build flag or configuration file. Deliverables must include: • a clean Android Studio project (Kotlin or Java) that compiles without external tweaks • doc...

I want to bring a straightforward ride-booking idea to life: users open the app, set pickup and drop-off points, and instantly secure an individual ride. Nothing fancy like car-pooling or luxury tiers—just reliable, on-demand transportation. I will launch on both iOS and Android at the same time, so a single codebase (Flutter, React Native, or similar) is preferred, though I’m open to fully native builds if you can justify the benefit. The flow should feel as frictionless as the big names: live map, real-time ETA, fare estimate before confirmation, in-app wallet or card payment, and a clean trip history. A lightweight driver interface and a small web-based admin dashboard will round out the ecosystem so I can manage drivers, rides, and payouts without extra tools. Deliverable...

I want to turn a single Android phone into a 24-hour ad-viewing machine that can reliably play through roughly 1,000 video ads every day and credit each completed view to my account so the revenue comes straight to me. Your job is to build the full workflow—from launching the ad source, through watching the videos in the foreground or background, to confirming each view and moving on to the next one without manual taps. Key needs • 100 % Android-only solution (no Windows, macOS, or Linux tools in the loop). • Works on a standard, non-rooted smartphone running the latest public Android release. • Handles the entire cycle automatically: open ad, let it run to completion, wait for the “Close” or “Next” prompt, then continue. • Stays u...

I’m preparing a round of deep-level AOSP changes and need an architect who already feels at home inside the framework layer. The focal point is refactoring Activity Manager Service, Window Manager Service and Package Manager Service so that new behaviour in System UI, the Launcher and the Android permissions/security model can sit cleanly on top. Your job is to help me translate a high-level product vision into concrete, review-ready patches and documentation. That means exploring design options, defining the right hooks in System UI, shaping launcher flow changes, and hardening or relaxing specific permission paths without breaking CTS. Please attach a detailed project proposal explaining: • how you would structure the AMS/WMS/PMS modifications • the strategy you use ...
