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 ...

Project Overview I have an Android gaming application called TaskTrophy which is live on the Play Store. The app is a WebView-based application where the game logic (Ludo, Sudoku, Quizzes, etc.) is hosted on a remote server (Hostinger) using PHP and JavaScript. I have implemented AdMob Mediation with Meta Audience Network and Unity Ads, but I am facing critical issues: Low Fill Rate: Only 1 or 2 ads show out of 10 requests. Mediation Errors: AdMob Inspector shows "No secure signal found" for Meta and "Bidder returned client error" for Unity. Bridge Issue: I need a reliable way to trigger Reward Ads from my hosted JavaScript/PHP game logic when a user finishes a game trial. Technical Stack Backend: PHP (Hosted on Hostinger) Frontend: JavaScript / HTML5 Games Android: Nat...

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’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: ...

Preciso de um desenvolvedor capaz de criar um launcher SA-MP totalmente funcional para a plataforma Android. A ideia é permitir que um jogador instale o jogo e entre diretamente em nosso servidor sem lidar com passos manuais ou arquivos soltos. Funcionalidades indispensáveis: • Instalação de data automática — o APK deve baixar e posicionar todos os arquivos necessários na pasta correta. • Configuração personalizada — quero poder definir opções básicas (gráficos, idioma, diretório) de forma descomplicada. • IP fixo — o launcher deve conectar-se sempre ao nosso endereço de servidor predefinido, sem que o usuário precise editá-lo. • Designer b&...

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 building a focused social-networking experience exclusively for Android. The first release centres on one core interaction: creating and managing friend connections. Users must be able to discover new people, send and accept requests, organise their contacts, and browse basic profiles in a fluid, Material-design interface. Messaging and photo sharing are out of scope for now; the architecture, however, should keep future modules in mind. You’ll receive my wireframes and brand assets on day one. From there I need a clean Android Studio project, preferably in Kotlin, targeting API 26+. Please follow standard MVVM patterns, use Jetpack components where they add value, and keep third-party libraries lightweight and well-documented. Deliverables • Complete, well-comment...

I need a custom-built Android application that lets me override every major device identifier for privacy testing purposes. The app must spoof the IMEI (confirmed by *#06#), serial number, all MAC addresses (Wi-Fi, Bluetooth, Ethernet), IP and port data, GPS location, and the Google Play Store email ID. Once a value is changed it has to survive reboots and appear system-wide—Settings, third-party apps, and any common USSD or diagnostic code must all report the spoofed data, not the genuine one. Because I want to use this on any handset or tablet, it should run across all Android versions and models. If root, Magisk modules, Xposed, or similar low-level methods are required, build those steps into the solution and document them clearly. A simple UI where I can enter custom values, ge...

My Tamil-language FM radio app is written in Java and built in Android Studio. A recent refactor has left me with a mix of syntax problems (mainly misplaced brackets and missing semicolons) and a couple of runtime crashes tied to fragment lifecycle calls. The issues are isolated to the UI layer: the now-playing fragment, its data-loading helper, and the activity that hosts them. I can point you straight to the offending methods, but I need a clean, compile-ready project and a brief note on what you changed so I can learn from the fix. You’ll be working with: • Android Studio (latest stable) • Java source only – no Kotlin in this module Acceptance: the project builds without warnings, launches, and the UI loads station data and switches fragments without thro...

I need a reliable Android developer to jump into my existing project and resolve a few lingering bugs. The code-base is stable overall, but a handful of issues are affecting the user experience and I’d like them cleaned up quickly so I can push the next release to Google Play. You will receive: • The current Android Studio project (Kotlin) • A concise list of the reproducible bugs with steps, expected vs. actual behaviour, and device logs where available I expect: • Clean, well-commented fixes that slot neatly into the existing architecture • No regressions elsewhere in the app—please test on at least two API levels • A pull request or zipped project, plus a signed APK so I can verify on real devices If this sounds straightforward for...

I need an experienced Android developer to work on existing mobile app to add more features and stabilize the product.

I am ready to turn a concept into a fully-functional Android application and need a developer who can guide the project from initial design through Play-Store-ready build. The scope is limited to Android only—no iOS version is planned—so I want the solution to take full advantage of the Android ecosystem and its latest SDKs. Key things I will look for are clean, maintainable Kotlin or Java code, a modern UI that follows Material guidelines, and a robust architecture that scales if we later add new modules. I will share wireframes and a concise feature list as soon as we agree on the collaboration, but you can expect standard app elements such as user onboarding, data storage (local or cloud, depending on your recommendation), and basic analytics. Deliverables I expect: •...

My fertility charting app still works perfectly on older devices, but the current build targets an outdated SDK and refuses to install on phones running Android 10 and above. The goal is simple: update the codebase so it compiles cleanly in the latest stable Android Studio, installs without warnings on Android 10 → 16, and keeps every existing screen and feature exactly as they are today. What needs to happen • Raise the compile/target SDK level and migrate any deprecated APIs or support-library calls to AndroidX. • Update Gradle, dependencies and signing configs, ensuring 64-bit compliance and Play Store policy readiness. • Retain the present UI, workflows and data model—no new functionality or design overhaul is required. Performance optimisations are wel...

Necesito una aplicación Android que intercepte las llamadas entrantes y, cuando el número coincida con la lista que yo defina, ejecute una de estas dos acciones: desviarla a un número alternativo o mandarla directamente al contestador. Solo me interesan esos “Números específicos”; los desconocidos o privados no deben verse afectados. Una interfaz completa no es indispensable, aunque agradecería un panel sencillo o incluso un archivo de configuración que me permita: • añadir / quitar números de la lista • indicar el número de desvío o activar el envío a buzón Lo prioritario es la lógica de desvío (opción “Ambas funcionalidades”). La app ...

I’m rolling out a new Android app and need real-world testers who will stick with it for a full 15 days. The process is straightforward: first join the Google Group at , then accept the Play-Store test invitation here Once you’ve opted in, install the build, open it at least once, and keep it on your device for the entire test window. Throughout the two-week period you’re free to use the app as little or as much as you like; what matters is that it stays installed so I can gather stability and retention data from Google Play Console. Deliverables I’ll be looking for: • Confirmation screenshot showing you’ve joined the Google Group and accepted the Play test link • Device/Android version details so I can match crash logs • A brief note ...

I need an Android-only Matka application built with a colorful, vibrant interface that feels lively and engaging from the first tap. The core flow is straightforward: new users sign up or log in, place their bets, and watch results update in real time without refreshing the screen. Behind the scenes, I will manage everything from an admin dashboard—numbers, odds, user accounts, payouts—so please wire the app to a robust admin panel that lets me adjust game data on the fly. Alongside the mobile build, I also want a lightweight static website that mirrors the app’s branding, explains how the game works, and points visitors to the Google Play listing once the APK is live. Deliverables • Android Matka betting app (APK + source) • Web-based admin panel with...

The goal is to build a dedicated Android CRM application for my business. The app has to streamline contact management, track sales activity from lead to close, and offer a straightforward way to handle customer-support conversations—all from a single, intuitive mobile interface. Core scope • Native Android build (Android Studio with Kotlin or Java) that runs smoothly on current OS versions. • Three integrated modules:  1. Contact Management: create, edit, search, import/export contacts.  2. Sales Tracking: pipelines, deal values, lightweight dashboards.  3. Customer Support: ticket logging, status updates, push notifications. • Secure, real-time cloud storage; Firebase, AWS, or a custom REST API are acceptable as long as data stays safe and...

I need an Android application focused on real-time broadcasting. The core of the product is a smooth, reliable live-streaming experience that works well on current Android versions and typical mid-range devices. Key functionality I must see at launch: • Live streaming with minimal latency • In-app push notifications to alert users when a stream starts or when a new highlight is available • Real-time chat so viewers can interact while watching A clean, modern UI is important, but stability and stream quality take priority. If you normally work with libraries such as ExoPlayer, WebRTC, or Agora, or if you typically integrate Firebase Cloud Messaging for notifications, please bring that experience to the build—you’re welcome to propose alternative tools if the...

I’m looking to enhance my existing Android mobile app. The core build is already live on Google Play, but it needs a focused round of improvements to move it to the next level. My goal is to refine performance, polish the user interface, and introduce a handful of quality-of-life features without disrupting the current user base. What I need from you: • Review and refactor key areas of the Kotlin/Java codebase to eliminate slowdowns and reduce battery usage. • Refresh screens with up-to-date Material Design components, ensuring full compatibility from Android 8 through Android 14. • Implement two to three small features I have queued (think in-app notifications, a lightweight onboarding flow, and a settings toggle)—I’ll supply detailed specs once we st...

I’ve just opened the internal-testing track for a brand-new productivity app on Google Play and need a handful of sharp Android users to put it through its paces. The build is Android-only for now, so you’ll simply receive an invite link, install from the Play Store, and start exploring every corner. Scope This is a full sweep across the user interface, performance, and security. I want to know how intuitive each screen feels, where animations stutter, how memory and battery hold up, and whether any action exposes data it shouldn’t. Feel free to dig in with tools such as Android Studio’s profiler, logcat, or OWASP-style checks if that’s part of your normal workflow; casual functional feedback is welcome too, provided it’s clear and reproducible. Deli...

I want a lightweight Android app that lets me create bills completely offline. The flow is straightforward: with a stylus I jot down the item name, quantity and rate, the app recognises my handwriting, drops each line into a table, and lets me add a rupee-value discount before totalling up. At the press of a button the bill prints to a Bluetooth thermal printer in a simple, clean layout—just the item list and the grand total. No shop name, GST or other headers. The same bill should also be saved locally as a PDF and be shareable instantly through WhatsApp. Every bill needs to be stored in an on-device history that I can browse inside the app or export later as CSV/PDF for wider reports. All features must stay fully functional without an internet connection. Deliverables &bul...

I have an idea ready to move from notes to a working Android application right away. Because time is critical, I need someone who can jump in, clarify the feature set with me on a quick call, then build and release a functional APK fast—ideally days, not weeks. You should be fully fluent with current Android SDK tools, Android Studio, and either Kotlin or Java (whichever lets you move quickest). I’ll supply wireframes or sketches the moment we start; you handle coding, basic UI styling, and packaging for submission to Google Play. Please include version-controlled source (Git) and a short read-me so I can continue maintaining the project after delivery. If you can start immediately, outline your proposed timeline for a first test build and final hand-off when you reply.

I have an existing Android application that already handles its core logic well, but it needs further work and additional features. The application also integrates with Firebase for backend storage. Here’s what I need: We will provide product details and what needs to be enhanced on a weekly basis and the changes are going to be in Android app. Key deliverables • Implement additional features as defined in the requirement doc that will be shared on a weekly basis. The initial work was done using Windsurf.

I’m launching an exclusive membership platform and need a dedicated Android app that gates premium content behind a secure login. The core requirements are straightforward: • Build a clean, responsive Android application (Kotlin or Java) that connects to my existing backend or a simple cloud database. • Implement a reliable authentication flow so only subscribed members can access the app. • Present members-only articles, videos, or downloads through an intuitive interface that can scale as I add new sections. • Provide basic push-notification hooks so I can alert users when fresh content goes live. I’ll supply branding assets and sample content. You’ll return: 1. The full Android Studio project with readable, well-commented code. 2. A brief setup g...

I have three Android apps that are essentially ready to ship, but I need an experienced developer to step in and guide them over the finish line. The core code is in place; what remains are the last-mile tasks—sorting out any lingering build or signing issues, tightening small bugs, and packaging each app so it is Play-Store ready. Here’s what I’m expecting from our collaboration: • Review each project in Android Studio, resolve compile-time or runtime errors if they appear, and confirm the builds are stable. • Generate signed APKs (or AABs) for all three apps, complete with proper versioning and keystores. • Provide concise notes on the changes you make so I can maintain the codebase moving forward. I have allocated a total of $100 for the trio o...

I need a lightweight, real-time chat application built exclusively for Android phones. The core focus is text messaging—no voice calls or media sharing for this version—so the interface and back-end can stay streamlined and fast. Key goals • Smooth one-to-one text conversations with instant message delivery and read receipts • Simple, clean UI that feels native to modern Android versions • Push notifications for new messages when the app is in the background • Secure user authentication (email, phone, or social sign-in—whichever you recommend) • Cloud-hosted database for message storage and basic user profiles You’re free to choose the stack you know best (Firebase, AWS Amplify, Supabase, or a custom REST/WebSocket back-end) ...

I’m integrating YouTube playback inside an existing Android app and need a small, self-contained Android Studio module written in Kotlin (Java-callable) that keeps the viewer inside the app at all times—no jumps to the YouTube app or browser. Core behaviour • Load and play any public YouTube video from its ID. • Standard playback controls must live in my layout: play / pause, seek bar, full-screen toggle. • Give the user a simple quality picker (144p → 1080p) and fall back to an automatic setting if nothing is chosen. Development notes – Target: current stable Android Studio + minimum SDK 23. – Prefer the official YouTube Player Library; if you’d rather wrap IFramePlayer or ExoPlayer with DASH/HLS streams, that’s fine ...

I’m commissioning a stripped-down, proof-of-concept chat app for Android that works even when the device is offline. The goal of this first milestone is to establish the technical backbone—not visual polish—so I can quickly validate the product idea and iterate later. Key scope • Single platform: Android (phone and tablet). • Data strategy: everything—account details, message threads, pending outbound messages—must persist locally in an encrypted SQLite / Room database and sync automatically once a connection is restored. • On-boarding & auth: users identify themselves with their phone number only; verification via SMS OTP or similar is acceptable. No email or social login for now. • Core interaction: one-to-one text messaging....
