From 358,985 reviews, clients rate our Android Developers 4.9 out of 5 stars.I’m looking for a developer who can take my core idea—currently summarised only as “Aku inggin 100”—and turn it into a functioning Android application. The concept is clear to me, but I need your expertise to shape the user flow, design the screens, and code the complete app so it runs smoothly on recent Android versions. Here’s what I already know: • Platform is strictly Android (Java / Kotlin or a modern cross-platform stack that compiles natively for Android is fine). • The main goal is to deliver a stable, production-ready APK that can be uploaded to Google Play when we’re done. I’ll provide the detailed feature list, wireframes, and any required assets once we kick off. You’ll help me refine the technical approach, se...
I need an Android and iOS application that lets users quickly discover Telegram communities of interest. The core flow is simple: a user opens the app, types or browses a term, and receives results that include both groups and channels. From there they can tap once and be taken straight into the chosen Telegram space via the standard join link. Key user actions • Search across public groups and channels in a single unified result set. • Narrow results by Group/Channel category and by minimum or maximum member count. • Tap “Join” to open the Telegram deep-link and subscribe immediately. I am happy with either a native build (Kotlin + Swift) or a cross-platform stack such as Flutter or React Native—as long as the final APK and IPA meet current Google ...
I want my stock Galaxy Note 9 (and if all goes well my Note 10+) running Android 13 or higher. At the moment the phone is completely untouched—no custom recovery, although bootloader is unlocked but no work has been done yet. I'd do it but I can't find the rom to download among the sea of advertisements and garbage. This bit below is from the AI here. You do it as you want, as long as you don't brick the phones. Your first step will be to flash a current TWRP build (or an equally reliable recovery) and confirm it boots. Once recovery is in place, install a stable, Android-13-based ROM. I’m open to LineageOS 20, Pixel Experience, or any other well-maintained option you trust, as long as day-to-day features such as calls, Wi-Fi, camera, S Pen and basic bankin...
My Samsung Galaxy Note 8 (currently on Android 9) already has its bootloader unlocked and I’m ready for a complete wipe, so there’s no need to preserve any data or apps. I’d like it brought straight up to Android 13 — with LineageOS 20, or another stable Android 13-based ROM if that proves more reliable. What I need from you • A fully functional installation of the chosen ROM, booting cleanly with no force-closes or missing hardware features (S-Pen, camera, Wi-Fi, Bluetooth, fingerprint, etc.). • Core Google services (MindTheGapps or equivalent) working out of the box. • Root access optional but welcome if it doesn’t sacrifice stability. • A brief, clear set of steps or a short screen-sharing session so I can repeat or undo the p...
I need a fully functional AI agent that plugs seamlessly into my existing website while also powering a companion mobile experience for both iOS and Android users. The core requirements are conversational intelligence, smooth integration with my site’s current tech stack, and a shared back-end so the same knowledge base drives consistent answers across all devices. You’ll handle everything from designing the agent’s dialogue flow and intent recognition to deploying the models on a secure, scalable back-end. Once the web component is live, I want wrappers or native apps published to the App Store and Google Play that call the same APIs, ensuring feature parity no matter where the user starts the conversation. I will provide access to the site’s repository and any b...
I need an Android app that can take a Blu-ray ISO—or a disc mounted to the phone—and turn it into a single .mkv file at 100 % variable-bit-rate. The finished movie must keep the original Dolby Digital track exactly as it is; no other audio formats are necessary, and no subtitles should be copied over. The flow I have in mind is simple: 1. “Load ISO” lets me browse to an image file stored on the device. 2. “Load Disc” detects a Blu-ray inserted through an external USB drive. 3. Press “Rip It” and the app starts converting, showing progress and an estimated time remaining. 4. When done, the resulting .mkv is saved to a user-selectable folder, ready to play. Under the hood you’re free to use FFmpeg or any other open-source librar...

I run interstitial ads in both my Android and iOS apps through several ad networks, but the current build gives me no clear picture of which network or campaign is actually pulling its weight. I need a clean attribution layer that captures every impression, click and post-click action, tags the event with the right source, and funnels the data into a report I can read at a glance. You’ll be working inside the existing flutter to add whatever SDK hooks, callbacks or server-side endpoints are required so that I can open a dashboard and instantly see which runner is driving the highest engagement or revenue. Whether the final stack involves Firebase Analytics, AppsFlyer, Adjust, a custom back-end parser, or something else, I’m happy as long as: • Each interstitial impressio...

I need a New Junior Level Developer from Pakistan. I need at low budget work I need work for long term
I have an unreleased mobile game that runs exclusively on Android and I need a fresh set of eyes to stress-test every feature before launch. Your task is strictly functionality testing: install the current APK, play through all levels and menus, push every button and setting you can find, and tell me exactly where things break or behave unexpectedly. Here’s what I’ll be looking for in the hand-off: • A concise bug report (spreadsheet or PDF) with clear steps to reproduce each issue, device/OS details, and severity tags (critical, major, minor). • Screenshots or short screen recordings whenever a visual reference will speed up fixes. • A final summary highlighting any game-stoppers I must resolve before release. Multiple Android devices or emulators are ...
Hi, I’m looking for a skilled Flutter developer to fix issues in an existing iOS app. The ideal candidate should have strong experience with API integrations and Firebase Cloud Messaging (FCM) notifications. There is one screen that needs to be fixed, and the app will also need to be deployed to the App Store. I will provide the App Store account for deployment. Detailed documentation will be shared with the selected candidate. Thanks.
I’m building Bigshot GROW, a single mobile solution that lets verified farmers, suppliers, businesses and everyday customers trade fresh mushrooms, micro-greens, organic vegetables and pure dairy without the usual middle-men or delays. The goal is a clean, intuitive Android and iOS experience that keeps every step of the farm-to-table journey visible—from harvest to doorstep. Core workflow • Farmers/Suppliers need a dashboard where they can create and update product listings, monitor live inventory, follow each order through packing and dispatch, and receive payments once delivery is confirmed. • Businesses and retail customers should be able to search and filter products quickly, place and pay for orders in-app, then watch the status change in real time and revi...
I’m building a practical, no-frills utility app that must feel identical on iOS and Android. The project is green-field, so you’ll be responsible for architecture, clean code, and publishing-ready builds. Core scope • Platforms: the app has to ship on both iOS and Android from a single codebase. • Nature: it’s a straightforward Utility app—nothing flashy, but it must be rock solid and fast. • Must-have features: – Offline functionality so key screens and actions work without a connection. – Secure user authentication (email / social sign-in is fine, as long as it’s safe). – Silent data synchronization that catches up automatically when the device reconnects. I’m open to Flutter, React Native, or a wel...
Project: iOS & Android Keyboard App Integrated with GoHighLevel API We are looking for an experienced mobile app developer (or small team) to build a custom iOS and Android keyboard application that allows users to quickly share marketing content inside messaging apps (SMS, WhatsApp, Messenger, Instagram, etc.). The core functionality is a custom keyboard that visually displays content tiles and allows one-click insertion/sharing directly into the active messaging app. Core Requirements - Build custom keyboard extensions for: --i OS -- Android - Keyboard displays visual content tiles (title, thumbnail, CTA). - One-tap inserts or shares content into the active messaging app. - Content is dynamically pulled via the GoHighLevel (GHL) API. - Content consists primarily of: -- Campaign UR...
I have a couple issues I need fixed in my flutter app. Screen recording of issue: 1) Registration doesn't properly complete on last step after profile photo is completed it says (Unexpected end of form) - Although account still gets created in firebase, 2) My bottom android menu is getting in the way of elements on the app during certain registration steps. *Your interest* *tell us more* *Years Celibate* If you can fix these successfully I have more ongoing fixes I'll need afterwards. NO VIBE CODING ALLOWED. After completion I need to push updated code to the repository and generate a new .AAB file.
I want to bring a dedicated real-estate property-listing experience to the mobile stores, so the entire project centres on a clean, reliable application that runs smoothly on both iOS and Android. The key workflow is simple: owners or agents add a listing in an admin interface, and house-hunters scroll, filter, map-search, swipe through photos, save favourites and tap a contact button that fires their enquiry straight to the agent. Here is what I need you to handle from start to finish: • Design and build the iOS and Android apps with a modern, intuitive UI. • Set up the back-end (Firebase, Supabase or a lightweight Node/Postgres stack are all fine) to store listings, images and user favourites, and to push real-time updates when new properties go live. • Implement cor...
Project Title Full-Stack Developer/Agency for On-Demand Home Service Marketplace (iOS, Android & Web) Project Overview I am launching a new on-demand service platform that connects customers with skilled professionals for at-home services. The business model relies on a high degree of transparency and real-time coordination. I need a scalable, high-performance solution consisting of a Customer App, a Service Provider App, and a Central Admin Dashboard. Scope of Work 1. Customer App: User registration/login (OTP based). * Service catalog with dynamic pricing (fixed and time-based options). * Real-time booking system with calendar slots. * Secure payment gateway integration (UPI, Cards, Wallets). * Live GPS tracking of the service provider. * Post-service rating and review system. ...
Looking for an Android engineer to fix a bug where foot scanning starts before the foot is fully positioned in the outline and gait videos appear to record but fail to upload; the role will focus on correcting scan start/stability logic, improving upload reliability (timeouts, retries, file finalization), and adding clearer in‑app guidance and error handling so users can successfully complete scans and uploads.
I want my Android copy of GTA San Andreas to feature a fresh fleet of police cars. I’m open to either approach—feel free to swap out the default cruisers or inject completely new spawns so we can toggle between both styles in-game. I already know which real-life models I’d like to see, but I don’t yet have the assets, so part of the job is sourcing or creating the vehicle files for me. Here’s what I expect: • The finished .dff and .txd (or equivalent) files for each car, fully mapped, optimised for the mobile version and tested so they won’t crash during high-traffic pursuits. • An easy installation package or step-by-step instructions so I can drop everything into my Android device without root complications. • Handling lines, carco...

I am ready to turn an idea for a social-networking mobile app into a live product available on both iOS and Android. I need a developer (or small team) who can guide the project from an initial clickable prototype all the way to App Store and Google Play approval. The core focus is connection—profiles, real-time interactions, media sharing, and push notifications are all part of the planned MVP. I have a basic feature map and branding assets; what I’m missing is the technical muscle to design the architecture, build the front-end, stand up a secure back-end, and integrate everything seamlessly. Typical tools that fit the brief include Flutter, React Native, Swift/Kotlin for any native-only components, plus a cloud backend (Firebase, AWS Amplify, or similar). I’m open to...
I’m ready to commission a purpose-built conversational AI agent whose core job is to support my ongoing development work. Think of it as a smart teammate that can interpret technical questions, surface relevant code examples, and respond with the right tone based on how the user is feeling. Scope • Primary function: development-oriented conversation and assistance (this supersedes typical “support” or “sales” roles). • Platform: I plan to embed the agent wherever a conversational AI interface makes sense—initially in a general chat environment, with the flexibility to port it later to web, mobile, or social channels. • Required AI capabilities: strong Natural Language Understanding coupled with Sentiment Analysis so replies remain...

I'm looking for an experienced mobile app developer to create a Learning Management System (LMS) application for both Android and iOS platforms. Core Features Needed: - Course Management: Ability to create, update, and manage courses. - Student Tracking: Monitor student progress and engagement. User Roles: - Students: Access courses and track their progress. - Administrators: Manage the overall platform and user activities. Experience in developing similar educational apps and familiarity with both Android and iOS development is a plus. Please share your portfolio with your bids.
I already have a detailed blueprint that spells out every formula and screen of my personal work app; what I need now is the actual Android build. The sole purpose of the app is to run those calculations locally—no databases, cloud calls, or extra features—then present the results in the layout I have drawn. I’d like the code written in Python so I can extend it later. If you normally package Python for Android with Kivy, Chaquopy, BeeWare, or a similar toolchain, that fits perfectly. Clear, well-commented code and a straightforward build process are important because I’ll be maintaining the project myself after delivery. Deliverables • Install-ready APK that runs on recent Android phones and tablets • Complete, editable source code plus any build sc...
I need a Unity developer to build a single-player, turn-based political strategy game. Multiplayer is NOT needed (no servers, no Photon/PlayFab). Everything should run locally. Platform: Windows PC (Android later is optional). Core loop: 1 turn = 1 in-game “day”. Player makes decisions → clicks “End Turn” → simulation resolves → shows results/news. Screens/UI: - World map with regions/territories (Risk-style regions, not hex tiles). - Country menu: Economy / Diplomacy / War / News. MVP mechanics: 1) Map & regions: each region has an owner and simple stats (income/resources/population – simplified). 2) Economy: national budget, income/expenses, a few basic actions (taxes/invest/army spending – keep it simple for MVP). 3) Army & w...
I need a lightweight Android library that can continuously listen for a single wake-word in Spanish and trigger my own voice-assistant module when it is detected. The focus is on practical, real-time performance rather than research-grade perfection, so moderate accuracy—roughly in line with popular consumer phones set to Spanish—is acceptable. A model that sits inside an AAR or Maven package, starts with a simple API call, remains in low-power mode, and throws a callback when the phrase is recognised is exactly what I’m after. I’m flexible about the underlying engine: TensorFlow Lite Micro, PocketSphinx, Snowboy-style approaches, or a custom on-device neural net are all fine so long as they run fully offline and do not require cloud calls. The only hard requirem...
I need an experienced mobile developer to hunt down and resolve a series of stubborn bugs that are undermining the current release of my app on both iOS and Android. Users are reporting crashes and unpredictable behaviour in production, so reliability is the top priority. What I already know • The problems present as classic bug-level issues (no new features are required right now). • They occur on both platforms, though the exact triggers may differ. • Codebases are native: Swift for iOS and Kotlin on Android, with a shared REST-based backend (Laravel). What I’d like you to do 1. Reproduce the reported crashes or malfunctions on a range of devices and OS versions. 2. Trace the root cause in the existing code, whether it sits in networking, data persist...
I need an experienced developer to create an AI-driven event planning app. The app should streamline the event planning process with the following key features: - Event Scheduling - Guest Management - Vendor Coordination - Document Storage - Curated Plans Based on User Inputs Integration with external services is essential, including: - Payment Gateways - Social Media Platforms Ideal Skills and Experience: - Proficiency in AI and app development - Experience with payment gateway and social media integration - Strong background in UX/UI design for a seamless user experience - Ability to create custom algorithms for curated planning Please provide a portfolio showcasing similar projects and a detailed approach to this development.
I’m building a straightforward mobile experience where users earn points every time they tap the screen. The job is Android-only, and the focus is on a clean, lightweight build that tracks taps, stores the running balance safely in the cloud, and syncs it back to the device instantly after each session. Here’s what I need you to hand over: • Registration/login (email or Google) • Main tap interface that increments and displays the balance in real time • Secure, lightweight backend—Firebase is fine, but I’m open to another service if you prefer—to keep balances tamper-proof • Simple admin setting (panel or JSON) so I can adjust the tap-to-point ratio without releasing a new build • Minimal Material-style UI with an ad placehol...
I want a clean, reliable Android application that lets my users execute share trades directly from their phones. Fast, error-free order placement is the heart of the project, so the workflow—login, order entry, confirmation, and status tracking—must feel smooth and instantaneous. Alongside the trading flow, I need a basic stock-charting screen. Think interactive candlesticks where a user can pinch, zoom, and scroll through price history before they hit the buy or sell button. I do not need advanced indicators or news feeds right now; keeping the interface focused on execution speed and a single chart view is more important than packing everything in up-front. Security and compliance are non-negotiable. All credentials and trade data have to travel over encrypted connectio...
I have a fully-coded Flutter POS application built for a restaurant environment and now I’m ready for the very last mile: getting it live on the App Store and Google Play. The app already handles table management, real-time order tracking and flexible menu customization, and it ties into an existing inventory management system. All screens, assets and icons are in place; what I need is someone who can: • Review the current Flutter project, make sure it meets Apple and Google publication guidelines and resolve any SDK or policy warnings. • Generate production-ready iOS and Android builds, including proper signing, certificates and provisioning profiles. • Walk me through (or directly handle) the submission process so the listings pass review first time, covering sc...
I'm seeking an experienced mobile app developer to create a comprehensive property listings app for the real estate market. The app should include: - Property Listings as the primary function - Search Filters: Allow users to refine searches based on various criteria - Interactive Map: Provide a dynamic map view of properties - Property Comparison: Enable users to compare multiple properties side by side Ideal candidates should have: - Proven experience in mobile app development - Strong portfolio demonstrating past work, especially in real estate or similar domains - Familiarity with integrating interactive maps and search filters Please include detailed project proposals with your bids.

I’m ready to turn my store concept into a dedicated Android application and need a developer who can guide the build from first commit to Google Play release. This project is strictly for Android, not cross-platform, so deep knowledge of Android Studio, Kotlin/Java, and current Material Design guidelines is essential. The app’s core mission is straightforward: allow users to browse products, add them to a cart, and check out securely. I already have a basic product list and brand assets; you’ll help translate those into a smooth shopping experience with clean navigation, responsive layouts, and a payment flow that meets PCI standards. Key delivery points: • Functional Android app (APK + Play Console-ready bundle) • Source code with clear, maintainable struct...
I Novastar TB40 player that still needs bound to the Vnnox cloud through the Viplex Handy app by an iOS or Android device. I What I expect from you • Confirm the correct physical setup: power, Ethernet, Wi-Fi antennas, and any required screen cabling. • We will guide you (video or phone is fine) while you install, open, and sign in to Viplex Handy on your device iPhone/iPad. • Configure the TB40’s network parameters so it can reach the internet securely. • Complete the binding procedure in Viplex Handy and verify that the player registers in my Vnnox cloud account. • Run a quick content push to prove playback is functioning. Once the player shows online status in Vnnox and plays the test content without errors, I’ll consider the job done.
I’m looking for an Android developer who can turn my rough concept for a land-survey app into a working MVP within 30 days. The app must: • Use the device’s GPS to log points accurately. • Provide real-time distance and area measurement tools. • Sync every reading straight to Firebase—the project will stay online-only, so no offline caching is needed. • Let users export their collected data (CSV or a similarly easy format) directly from the app for further analysis. I already have a Firebase instance waiting; you’ll wire the authentication, real-time database / Firestore, and basic storage needed for the exports. Clean, readable Kotlin code, a straightforward UI, and full project files in Git are part of the expected hand-off, along with ...
I need my existing Base44 web app wrapped and released as fully-featured native builds for both iOS and Android. The current codebase and all design assets are ready to hand over, so you can focus on turning the site into installable apps, wiring up billing, and guiding me through the store approval process. Core scope • Wrap the Base44 front-end (Capacitor, Cordova, or any modern alternative you prefer) so it installs cleanly on iPhone, iPad, and the vast majority of Android devices. • Add in-app purchase flows that offer a monthly subscription using Apple In-App Purchases and Google Play Billing. A successful subscription must unlock the exclusive content access inside the app. • Configure bundle IDs, certificates, app icons, screenshots, privacy details, and all othe...

The game must support: Offline play Online multiplayer using join code No betting, no real money, no gambling This is a fun, family-friendly game, fully compliant with Google Play Store policies.
I want to release a fast-paced first-person action game exclusively for Android and have it monetised through Google AdMob from day one. The concept is deliberately simple—think quick matches, fluid controls, and instant replayability—because the real goal is to generate reliable ad revenue rather than build a sprawling AAA title. Here is what I need from you: • A complete Android build (APK + AAB) and full source code, created in a mainstream engine such as Unity or Unreal so I can iterate later. • Seamless AdMob integration for interstitial and rewarded ads, with clear instructions on how to swap ad-unit IDs before release. • Basic but polished UI/UX: start screen, settings, pause menu, and an in-game HUD that fits an action shooter. • Optimised per...
