Android App Development Jobs

I’m opening a closed beta on Google Play for my new educational app and need 100 real users to join the tester program, download and install the current build, then exercise it for at least a couple of sessions. The insights I’m looking for focus on overall app functionality, so please keep an eye on how smoothly the navigation flows, how quickly each screen loads, and whether any errors or crashes appear. Because the target audience uses a mix of Android phones and larger-screen tablets, tests must be performed on both device types. To make it easy, I’ll share a private Play Store opt-in link. Once the quota of 100 installs is reached, I’ll close the listing and gather your findings in one structured report. Feel free to supplement written notes with screenshots, ...

I need a clean, native Android application that works as a focused productivity tool centred solely on task management. The core flow is simple: users create tasks, edit them, mark them complete, and view an always-updated list of what still needs attention. Fast load times, smooth transitions and a clutter-free Material-compliant UI matter more to me than a long feature checklist. Key features and behaviours • Add, edit, archive and delete tasks locally (Room or Realm preferred, but I’m open if you can justify another lightweight on-device store). • Optional grouping or tag system so users can sort their list quickly. • Swipe or long-press gestures for common actions. • Due-date picker with basic notifications. Push is not required at launch; local ale...

I have already wrapped up all product design, UX, and UI work for my new Android app and now I need the engineering muscle to bring it to life. Your main mission is two-fold: first, build system-level battery-optimization enforcement so the app behaves responsibly in the background without being killed by Doze or aggressive OEM policies; second, hook the project into Firebase. On the Firebase side, the app must support Authentication and Realtime Database right out of the gate, with Cloud Messaging for push notifications and Remote Config for on-the-fly feature tuning. For sign-in flows, I only need email-and-password and Google Sign-In. You will be working from a clean, well-commented repository that already contains the complete UI layer. I’ll provide the Figma files, current Gra...

I’m ready to turn a simple game concept into a playable Android prototype and need a mobile-game developer who can move quickly from idea to on-device build. Here’s what I need at this stage: • A runnable Android APK plus complete source files set up in a common engine or native Android Studio project—your choice, so long as it’s easy for me to open and extend. • One short, self-contained level that shows the core gameplay loop with placeholder art and sounds. • Basic UI flow: splash screen, main menu, in-game HUD, pause/restart, and end-of-level summary. • Clean, well-commented code structured for easy future expansion. • Smooth performance on recent mid-range Android phones. I’m flexible on tools—Unity, Unreal, Go...

I need a small, self-contained Android application that runs only on my phone—no cloud, no remote server. The goal is to catalogue dancer profiles so I can show, search, and share them quickly during auditions. Core workflow • Create a new profile with name, age, height, full measurements, and the city the dancer is based in. • Attach multiple photos to each profile (photos are the priority), with the option to add a video clip later. • Browse or instantly search by city; that is my main way of organising the list. • From any profile, tap a button to share it straight to WhatsApp or Instagram without exposing the rest of the database. • Keep everything offline in an on-device database (Room or SQLite is fine). A simple “Backup / Restore&rdquo...

I want to bring a very focused Android app to life: its single goal is to help people relax by letting them browse and play short, soothing sound effects. Think of rain drops, crackling fire, or soft wind—nothing fancy beyond an intuitive catalogue and crisp, uninterrupted playback. Here’s what I need built: an Android application (Kotlin or Java, your choice) whose core functionality is sound playing. The user opens the app, taps a tile or button representing a specific sound effect, and the audio starts instantly. They can pause, stop, or switch sounds without lag. No social networking, e-commerce, or bulky productivity suites—just a clean, lightweight relaxation tool. Deliverables • Complete Android Studio project with well-commented source code • Signe...

I want to launch a clean, user-friendly mobile application that lets customers in Saudi Arabia book limousine services directly from their phones. The app’s sole focus, for now, is booking rides. Users should be able to choose between two ride types—single trip or round trip—and confirm each reservation instantly within the app. A seamless, secure payment gateway is essential. Once a rider selects the trip type, the flow should proceed to fare display and in-app payment (credit/debit cards and common local wallets; advise me on the best SDKs). Real-time vehicle tracking, driver choice, and other advanced options can wait for later versions; I first need a rock-solid booking core. Deliverables • iOS and Android builds (store-ready) • Admin or dashboard pane...

Scope • Design a modern, on-brand UI that feels intuitive on the latest Android phones and tablets. • Build core screens: home, product highlights, brand story, promo/offer section, and a share-with-friends feature. • Integrate push notifications so I can alert users to new campaigns or events. • Add basic analytics (Firebase or similar) to track installs, sessions, and share actions. Deliverables • Production-ready APK plus source code (Kotlin or Java). • All design assets and fonts in edit...

I’m building a dedicated Android application that lets users browse, purchase, and instantly access digital products. Think of items such as e-books, audio files, software keys, or any downloadable content that can be delivered straight to the user’s device the moment a transaction is confirmed. What I’m looking for is an Android developer who can take this concept from clean architecture through to launch on Google Play. The core of the job is creating a smooth catalogue and checkout experience optimised for mobile, then handling the secure delivery of the purchased files. Clean code, reliable state management, and attention to UX details (progress indicators, purchase confirmation, download status, error handling) are all important to me because the product is intangib...

I’m planning to launch a brand-new social networking experience focused exclusively on Android users and I need a skilled developer—or team—to turn the concept into a fully functioning app. Scope of work The job covers everything from initial architecture through Play Store release. You’ll be responsible for designing the UI/UX, building the front-end in Kotlin or Java, creating the back-end (Firebase, Supabase, or another cloud backend you’re comfortable with), and integrating standard social features such as real-time chat, user profiles, newsfeed, push notifications, and media uploads. Clean, well-documented code and a modular structure are essential so the project can scale or later be ported to iOS. Deliverables • Interactive high-fidelity mock...

I need a full-function Android social networking application built from the ground up. The core idea is simple: let users create accounts, build a profile, connect with others, and share content in real time. I’m looking for a clean, modern UI that takes advantage of native Android components, built with Kotlin or Java in Android Studio, and underpinned by a solid, scalable backend (Firebase, Supabase, or your preferred equivalent). Key goals • Smooth onboarding: email, phone, or third-party sign-in • Personal profiles with editable photo, bio, and basic stats • Post feed supporting text, images, and short video • Real-time likes, comments, and push notifications • In-app messaging or chat to keep conversations flowing • Lightweight admin dash...

AI Assistant Feature Project Description: We are developing an AI Assistant Android app that currently works fine when it’s in the foreground, but stops responding in the background We need an experienced Android and Java developer who can implement a background service or foreground notification-based system so that: The AI assistant continues to run even when other apps are open. It can receive and execute commands from notifications or voice input while running in the background. The app should maintain minimal battery usage and comply with Android’s background execution limits (Android 10+). Key Requirements: Strong experience with Android Services (Foreground Service, WorkManager, BroadcastReceiver, etc.) Java-based Android app expertise (Kotlin is a plus) ...

I have an existing Android APK but no accessible source code. I need the app fully de-compiled, cleaned up, and re-assembled so I can continue development. Once the codebase is restored, I’ll want a few targeted edits—mostly refactoring and minor feature adjustments that we’ll clarify together after you review the decoded project. What I expect from you: • Produce a readable, gradle-based Android Studio project reconstructed from the current APK. • Implement the agreed code changes, then compile and deliver a fresh, working release APK plus signed debug build. • Document every modification so I can pick up future work without hand-holding. You’re free to use jadx, apktool, or any equivalent reverse-engineering toolchain as long as the final pr...

Referral Mobile App – CS Lawncare Overview CS Lawncare would like to develop a public, standalone native mobile application for both iOS and Android. The primary purpose of the app is to enable customer referrals through unique referral codes, while also serving as a simple service promotion tool.

I need a complete build that covers website, Android and iOS releases in one coherent code-base. The visual language is minimalist and clean, so every screen should feel light, fast and distraction-free. Core flow • Public landing page that briefly explains the service and funnels visitors to sign-up. • Email-and-password account creation and log-in. • Once authenticated, users land on a main dashboard that pulls tabular data from the integrated database, that I will fill from my external application. The table must be fully responsive, sortable and paginated to keep the UI snappy on mobile devices. • Stripe integration for subscription management: checkout, plan changes, proration, and a “Download invoice” link that fetches the PDF directly from S...

I need a clean, performant Android e-commerce app built from the ground up. The core of the project revolves around a smooth product catalogue experience that lets shoppers browse, search, and filter items without lag. A secure, fully integrated payment gateway must be in place so buyers can complete purchases inside the app rather than being bounced to a browser. Shoppers should also be able to leave ratings and text reviews, both to boost trust and to help with product discovery. Sign-in will rely on social media credentials only—no traditional email/password flow. If you prefer Firebase Authentication, Facebook/Google SDKs, or another reliable SSO option, that works as long as setup is straightforward for end users and easy for me to manage. Because I will eventually submit the ...

I’m ready to bring my online store to Android and need a talented developer who can translate a straightforward e-commerce concept into a smooth, modern mobile experience. Because I’m starting with Android only, the build should be fully native (Java / Kotlin) or cross-platform so long as the Android release is polished and Play-Store-ready. Scope • End-to-end development of the Android app—from clean architecture and intuitive UI right through to final deployment. • Core e-commerce flow: product browsing, cart, checkout, and secure payment processing. (If you have proven plug-ins or gateway SDKs you prefer, let me know; I’m flexible as long as PCI-compliant options are in place.) • Admin-friendly integration so I can add or update inventory wi...

I’m building a lightweight yet polished video player for Android that feels as snappy as MX Player. The essentials are straightforward: it must play local MP4, AVI, and MKV files flawlessly and let the viewer load and switch subtitles without hiccups. A clean, modern look matters to me, so please wire in theme customization (at minimum light and dark, with room for future accents). I’m not asking for streaming, gesture navigation, or custom button layouts right now—those can stay on the wish-list until the core experience is rock-solid. I’m fine with ExoPlayer, Media3, or a comparable native library as long as you keep the codebase modular (Kotlin preferred, Java acceptable) and target the latest stable SDK. Smooth seeking, orientation changes that don’t...

I’m building an Android-only sports application that focuses on delivering fresh match highlights to fans and alerting them the moment a new clip is available. The core of the project is straightforward: smooth video playback, a clean Material-inspired interface, and reliable real-time notifications. Here is what the finished product must do: • Install on Android 10+ and present a scrollable feed of recent highlights pulled from my existing JSON/CDN source. • Stream each clip in HD without stutter and allow basic share functionality. • Trigger push notifications (Firebase Cloud Messaging or a comparable service) within seconds of a new highlight being published. • Follow best practices for maintainable, modular code so I can layer in live score updates or player ...

I am ready to purchase a fully developed Teen Patti (3 Patti) game that already runs smoothly on Android devices. The ideal package lets me open it in Android Studio, build without errors, and publish under my own account.

My web application is already live, backed by Supabase and managed through a GitHub repository. The next milestone is a fully native mobile experience—Swift for iOS and Kotlin (or Java) for Android—mirroring the core web-app workflow without compromising performance or security.

I’m building a complete digital solution for a home-cleaning service and need someone who can handle both the development of the product and the hosting setup that keeps it running smoothly. The product itself breaks into two parts: 1) An Android application that lets customers: • browse local cleaners • book appointments through a real-time calendar • track their cleaner’s arrival via GPS • leave ratings and written reviews after each job 2) A responsive web portal that mirrors the same customer experience for desktop users and includes an admin dashboard where I can approve cleaners, adjust pricing, review bookings and reply to customer feedback. Alongside coding, I need you to configure secure hosting (I’m open to AWS, Digita...

Three finished Android apps are ready for their final enhancement: integrating a hosting layer so user data and media can live on a reliable back-end instead of locally on the device. All UI assets, icons, and existing source code are packaged and waiting in the repository; the work now is purely feature addition, not bug fixing or UI tweaks. Scope of work • Choose or configure a hosting solution (Firebase, AWS, or any lightweight VPS—whichever fits best). • Wire the back-end to each app so login, uploads, and simple read/write actions pass through tested API calls. • Update the project settings, build files, and pro-guard rules where needed. • Provide clear build instructions and a short “read-me” detailing endpoints, keys, and deployment ste...

I am rolling out an in-dash Android interactive display and need a seasoned AOSP specialist to turn the stock source into a lean, security-hardened custom ROM. The target hardware is a car-grade unit that hosts a camera alongside proximity and accelerometer sensors, so the build must include the right HALs and permissions for those components. What I want you to handle: • Fork the AOSP branch that best matches our SoC, import or craft the correct device tree and board-config, and fine-tune the kernel where necessary. • Strip every Google Mobile Service while preserving base Android stability. • Apply low-level security tweaks (SELinux policy work, verified boot, hardening flags). • Set up seamless OTA delivery (delta or full images) so field upgrades stay painless. &bu...

I need help lifting my Android app’s visibility on Google Play. The main metric I care about is a higher position in Play Store search results, so every backlink and mention you create should point toward that outcome. I already know the two content formats I want to lean on—guest posts placed on relevant, reputable sites and well-crafted press releases syndicated through channels that carry weight with Google News. You can suggest other tactics if they genuinely support ranking gains, but guest posting and news-style distribution must remain the core of the campaign. Your work will cover everything from prospecting suitable domains, drafting copy that highlights the app’s features, to securing do-follow links that Google actually indexes. Please track each placement in...

I need to duplicate my existing “TalkingStatues” mobile app, give it a new Talking Statues, so the app will only work for 1 one specific city, and ship the renamed build to both Google Play and the Apple App Store under our developer account. No code, design, or feature changes are required—the only differences must be the package/bundle identifiers, display name, and store-listing assets. All resources are ready on my side: I already have full source-code access, database credentials, and a fresh set of icons and screenshots for each store. The current back-end database sits on GoDaddy; a full copy of that database must be created so the new app points to its own instance while preserving all existing data. Core tasks • Adjust bundle IDs / package names and ...

I already have the full AOSP source checked out and the proprietary blobs for a piece of dedicated in-vehicle hardware. What I need now is an Android engineer who has been through the full custom-ROM cycle before and can take the lead on turning that raw tree into a production-ready build. Scope of work • Strip every trace of Google Mobile Services and replace only what is strictly necessary with open-source or in-house components. • Harden the system: SELinux in enforcing mode, verified boot, secure default props and permissions, plus any kernel-level mitigations you normally deploy. • Update or create the device tree and BoardConfig so the microphone, speakers, Bluetooth and the built-in camera work flawlessly; the unit does not rely on a touchscreen, so please make...

I’m ready to turn my idea into a fully-functional Android application and need a developer who can guide the process from concept to Google Play release. At this stage I have the core concept and a handful of rough sketches; what I need now is help refining the user flow, designing an intuitive interface, building the backend logic, and packaging everything into a clean, well-tested APK. You’ll be working exclusively for the Android platform, so familiarity with current SDK versions, Kotlin or Java, Android Studio, and the play-store submission process is essential. If you can also advise on best-practice architecture (MVVM, Clean Architecture, Jetpack components) and integrate common services such as Firebase or in-app billing, that’s a plus. Please let me know: ...

I already run and have wrapped it in an Android WebView (built with WebIntoApp). The shell works, but it still feels like “a website in a browser.” I now need a true app experience. The first milestone is a secure authentication flow that lets people register and sign in with BOTH email-and-password and phone-number-plus-OTP. A user who creates an account inside the app must be able to use the same credentials on the website, and vice-versa. I’m undecided about adding social logins; please outline the extra effort and I’ll decide once I see the impact. You’re free to suggest the tech—Firebase Auth, a WordPress plugin that ties into my existing stack, or a lightweight custom backend—just explain why your choice is the best match. If you can bundl...

I want to launch an Android-only application that showcases property listings and layers in practical AI assistance to make the experience smarter for both managers and renters. At its core the app must let a property manager add, edit, and remove listings (images, price, availability, basic details). The AI component should work behind the scenes—think auto-tagging amenities from photos, suggesting competitive pricing ranges, or surfacing the most relevant homes to a tenant based on their previous in-app behaviour. I’m open to the exact technique you use (TensorFlow Lite, ML Kit, embedded models, or a lightweight cloud call), so long as it stays responsive on typical mid-range Android devices. No third-party property-management or CRM integrations are required; the app should...

The current production build of my app is intermittently crashing, and I need a clean, targeted code update to eliminate these functionality-related bugs without introducing new issues. The crashes appear after recent OS updates and seem tied to memory handling inside two core screens; logs point to null pointer exceptions in the data-binding layer. You’ll receive: • Full Git repository access (Android, Kotlin + a small legacy Java module) • Current crash logs from Firebase Crashlytics and Logcat • A short video that reproduces the issue on two devices What I need from you: 1. Diagnose the root cause of the crashes. 2. Refactor or patch the affected classes so the app runs reliably across Android 8-14. 3. Commit code in a separate branch with clear co...

I need a straightforward yet polished online-shopping app for my supermarket, available on both iOS and Android. The primary goal is letting customers browse products and place orders from their phones; everything else is secondary to a smooth buying experience. Because I’m not on a tight deadline, you’ll have the freedom to choose the tech stack—native Swift/Kotlin or a cross-platform approach such as Flutter or React Native—so long as the final result feels fast and intuitive. Key deliverables I’d like handed over: • Shopper-facing app for iOS and Android, ready for App Store and Google Play submission • Clean, well-documented source code • Simple admin or API hook that lets me update products, prices, and stock in real time • I...

I have a live website built with Dart/Flutter for the web, and I now need it packaged as a fully working Android APK while giving the interface a fresh look. The new styling should cover the entire color scheme—backgrounds, fonts, and buttons—along with updated typography that feels consistent across pages. I also want the layout streamlined: the navigation menu needs a cleaner structure, content blocks should align responsively on all screen sizes, and the footer should be reorganised for better usability. You’re free to use your preferred workflow (Flutter build, Android Studio, VS Code, etc.) as long as the finished APK installs without issues on Android 8.0+ devices and mirrors all existing functionality. Deliverables 1. Updated Flutter/Dart source with revised co...

I’m running a rapid compatibility study for an upcoming viral TikTok campaign, and I need help from people who still use older or less-common Android smartphones—often called “live devices.” Your job is simple yet critical: push our landing page to its limits and tell me exactly where it breaks or misbehaves. What you’ll do • Open a private test link on your Android phone (any brand or carrier, the older the better). • Follow a short script that forces heavy scrolling, repeated form submissions, and fast video playback. • Note visual glitches, layout shifts, slow loads, or crashes. • Capture a quick screen recording (native recorder or a lightweight app) while you test. • Send me a brief report that includes your device mode...
