Android Studio Jobs

I need an experienced Android team to build two separate Play-Store-ready apps, starting with the Medicine Selling App. The ride-hailing platform will follow once the pharmacy solution is live. Medicine Selling App – phase one The core experience is a clean, secure mobile storefront where customers log in with phone-number verification, search medicines by name, browse existing product categories, upload a prescription when required, add items to cart, pay in-app, and track delivery in real time. An internal courier module should let my dispatchers assign, monitor and update order status from preparation through doorstep drop-off. Rider Booking App – phase two After the pharmacy app is published, I’ll move straight to the Uber-style solution: passenger and driver si...

I'm looking for immediate support to resolve the "Error 3 - Code Already Used" I receive when attempting to upload an AAB package to the Google Play Console. Current Situation • The app compiles and launches successfully locally. • When uploading the AAB release, the console blocks the publication, reporting Error 3 with the message "Code Already Used." What I Need 1. Quick analysis of the Gradle project to identify the cause (versionCode/versionName, signature, automatic increments, any pending artifacts). 2. Correction of the offending parameters and generation of a new signed AAB. 3. Successful upload of the release to the Google Play Console with my confirmation. I will accept the job when: • The corrected AAB is accepted without errors by the...

The REST APIs for my platform are already live and documented; what I now need is a skilled Flutter developer who can turn my rough sketches into a polished, custom-designed Android app. Material widgets alone won’t cut it—I’m aiming for a distinctive look and feel that reflects my brand, so you’ll be building bespoke components rather than relying on stock Material Design. Here’s how I picture the workflow: • You translate my hand-drawn screens and notes into clean, responsive Flutter layouts that look great across the Android device range. • Using Dart, Flutter 3.x and Android Studio (or VS Code if you prefer), you wire each screen to the existing REST endpoints, handling authentication, JSON parsing and state management smoothly. • Thro...

I already have the full source code for a working Satta Matka mobile app and backend. My goal is to turn it into a completely new, white-label product under a different name, logo, icon, and colour palette. Every trace of the old branding must disappear so the app feels as though it was built from scratch for my company. Scope of work • Re-skin: replace the app logo and name, app icon, and global colour scheme in both Android and iOS builds (Android Studio / Xcode). • White-label cleanup: update package IDs, splash screens, notifications, web views and admin panel so no original branding remains. • Server migration: deploy the existing backend on a fresh cloud instance of my choice, attach a new domain, configure SSL, and make sure the app connects flawlessly. &bull...

I’m building an Android-based equalizer app whose very first mission is solid, low-level I2C communication. The app must be able to discover and talk to an external audio-amplifier chip on the bus, read and write its registers in real time, and let a physical remote-control key trigger those same EQ changes inside the UI. I2S handling can follow later, but rock-steady I2C comes first. You may choose any practical route—GPIO lines available on an Android SBC, a USB-to-I2C bridge, or another proven method—so long as it runs on a stock Android build. I can supply the amplifier’s data-sheet and register map as soon as the project starts. Deliverables • Full Android Studio project (Kotlin or Java) with clean, well-commented source • Working APK that finds...

I already have a fully-built Android application and the complete source code is ready for you in Android Studio. Before I take it live again, I need a short round of polish: • Triage and resolve a handful of bugs that surfaced during my own testing. • Tweak or optimise existing features—nothing brand-new, just making what is already there work more smoothly and reliably. Once those fixes are in place, I also need hands-on help getting the app through the Google Play Console, including preparing the release build (AAB), completing the store listing assets, handling policy checks and guiding it all the way to an approved rollout. Please be comfortable with Play Console best practices, policy compliance and the most common rejection traps so that the submission sails...

My Android app is ready to go—code signed, fully tested, and sitting in its final AAB build. I already have a verified Google Play Console account; what I need now is a smooth, error-free deployment. Here’s the scope: • Create the production release in Play Console, upload the AAB, set up the release notes, and handle any bundle optimiser warnings. • Populate the store listing with the assets I provide (screenshots, icon, short and full descriptions, privacy policy URL). • Configure pricing, countries, content rating, Data safety form, and all policy declarations so the submission is 100 % compliant. • Walk me through the review and rollout steps so I understand how to push future updates myself. A successful hand-off means the app is live (or at l...

Six years ago I released a small Android billing application; today all I have left is the signed APK. The original source code is gone, so I need a developer who can either clean-decompile the APK or, if that proves impractical, rebuild the project from scratch in the latest Android Studio while matching the existing workflow. Core workflow to preserve – billing and invoicing, – customer management, and – reporting and analytics. On top of that I want to add inventory management and a secure user-authentication layer. I have not fixed a login method yet, so you are free to recommend email/password, biometric, social sign-in or any modern alternative that fits the current Google Play guidelines. I will provide the live APK and a short screen-capture showing how...

I will give you a working Android application that I own the rights to and need it rebuilt from the ground up. All screens, flows, wording, colours, animations and behind-the-scenes logic must match the reference exactly, so a user moving between the two apps notices no difference. You are free to use Kotlin or Java in Android Studio as long as the finished code is clean, well-commented and ready for future updates. If the original app relies on a simple server or local database, mirror that structure; if it calls external APIs, point the new build to the same endpoints. I will supply any keys or assets you need. Deliverables • Complete Android Studio project with source code • Release-ready APK (and, if possible, an App Bundle) • Brief build/run instructions so I can ...

My production Flutter app runs on both iOS and Android. Two elusive issues have slipped through testing and I need them eliminated: • On a completely fresh install the very first launch can stall on a blank screen intermittently. It never recovers until the user force-closes or restarts the app. • After the user completes OTP verification, the final signup submission sometimes fails and the flow hangs. The problem is random and difficult to reproduce on demand. Deliverables • Verified fixes for both issues on iOS and Android builds • Brief technical report summarising root cause, code changes, and test steps • Clean pull request ready for merge and release Once your patch survives my TestFlight and internal QA rounds, the job is done.

I want to turn my idea for a social-media-focused Android application into a working product. The core concept is a modern platform where users can create profiles, share posts, interact through comments or reactions, and receive real-time updates via push notifications. I already know this will be Android-only for now, so every design, interaction, and line of code should feel native to current Android UX patterns (Material 3, latest Jetpack libraries, Kotlin preferred). Here is what I need from you: • A complete, well-structured Android project with clean architecture that I can open in Android Studio. • A functional APK for hands-on testing, plus release-ready build settings. • Source code fully commented in English and delivered through a private Git repository. ...

I need a clean, lightweight Android utility focused purely on file management—specifically, moving files from one device to another. Think of it as a straightforward “send-receive” tool that a user can open, pick any file on local storage, and push it to another phone or tablet without fuss. Core requirements • It must excel at file transfer between devices. I’m open to the underlying transport method—Bluetooth, Wi-Fi Direct, nearby-share style over local network, or a combination—so long as transfers are reliable and fast. • The interface should follow current Material guidelines so the listing looks polished on Google Play. • No cloud backup, compression, or other extras are needed at this stage; keeping the scope tight is a prior...

I need an Android-only e-commerce application whose first release concentrates on a smooth shopping-cart flow and a secure, hassle-free checkout. Think of it as the purchasing core of a larger store: products are already stored in a backend API I provide, so your mission is to turn browsing items into confirmed orders with as few taps as possible. Key requirements • Kotlin (preferred) or Java inside Android Studio • Add-to-cart, quantity edits, promo-code handling, and real-time basket total updates • Multiple payment gateways (Stripe is mandatory; PayPal is a nice-to-have) with tokenised, PCI-compliant processing • Order confirmation screen + push/email receipt trigger • Clean MVVM architecture, Retrofit for API calls, and Firebase Crashlytics for basic...

I need a reliable Android specialist to build a lightweight mobile banking application focused on smooth bank-to-bank transfers. The core flow should let users view their current balance at a glance and then initiate a transfer in just a few taps, all safeguarded by biometric login (fingerprint or face ID only—no PIN fallback). Performance, stability, and security come first: the APK must run confidently on every current Android phone and handle sensitive data with proper encryption, secure networking, and up-to-date libraries. Pair that with a clean, contemporary Material 3 interface so users feel at home from the first screen. Deliverables • Full Android Studio project with 6readable, well-commented Kotlin or Java code • Modular architecture that keeps business ...

I’m looking to turn my concept, FIKRI NAHKLARAFI, into a fully functioning Android application. The core requirement is a solid user-authentication flow—sign-up, secure login, and session management—built with best-practice encryption and Google Play guidelines in mind. Scope • Build the Android app from scratch, including clean UI screens for onboarding, login, and a simple home dashboard. • Implement secure authentication (email/password or social sign-in—whichever you recommend for speed and security). • Structure the code so additional features—such as push notifications or in-app purchases—can be added later without major refactoring. Deliverables • APK and signed bundle ready for Google Play submission. • Well-comme...

I am creating SARAZ EASY POS, a lightweight point-of-sale application for Android that must run smoothly offline. The scope is focused and the budget is intentionally lean, so clean, uncomplicated code is essential. Core functions • Single-user login for the admin. • Product catalogue management—add, edit, delete. • Cash-only billing that instantly records each sale. • Automatic daily sales report saved locally for later export. • PIN-based authentication for quick entry while keeping data secure. • A strictly minimalist UI in English so any staff member can learn it in minutes. Timeline & workflow I would like the first working APK in about a week, refinement in the second week, and final hand-off by day twenty. Payments will be rele...
