We currently have a Android App which has a interactive animation built in Java and Android XML, you can check what this animation looks like by clicking a topic in the app and then clicking any purple line. We want to add some panels on the homepage that displays each of the categories that we have and when these are panels are clicked we want these boxes to have a press animation. When the next page is loaded which has the topics for the chosen category that’s been selected we can split by latest etc. We may also want to change the page which lists all the topics into one topic per line and also animate the pressing of the topic in some way. I will share any further details required when we speak on chat. This may require you to add categories to our website database so tha...

...brand-new social networking experience that will live exclusively on Android. The goal is to give users an intuitive space to connect, share photos and short videos, chat in real time, and receive instant push notifications—everything they expect from a modern community app, wrapped in a clean Material Design interface. You’ll take the lead on end-to-end Android development, so solid Kotlin or Java skills are essential. A cloud back-end (Firebase, Supabase, or a solution you recommend) will handle authentication, media storage, and real-time data. I’m keen on scalable architecture, readable code, and smooth UI/UX transitions; if you excel at Jetpack Compose, even better. Deliverables • Fully functional APK ready for Play Store submission • Comple...

Core scope • Define feature set and user flow with me, keeping the initial release tight but compelling. • Design high-fidelity UI/UX mock-ups that match Android guidelines. • Develop the Android app (Kotlin or Java, though Kotlin is preferred) with a modular codebase and clear architecture (MVVM, Clean, or similar). • Set up a lightweight backend (Firebase, Supabase, or a simple REST API) that handles authentication, real-time chat, push notifications, and basic media sharing. • Integrate analytics and crash reporting for early user feedback. ...

I have a React front-end paired with a Java Spring Boot back-end that is already running locally; now I need it live on Microsoft Azure. The plan is to host the Spring Boot API and the React build on Azure App Service and wire everything up to an Azure SQL Database. What I need you to do • Create or refine the Azure resources (App Service + Azure SQL Database). • Set up the build and deployment workflow so every push to the repository triggers a fresh deployment of both the React static files and the Spring Boot jar. Azure DevOps or GitHub Actions is fine as long as it is reliable. • Configure environment variables, connection strings, and SSL settings so the API talks securely to the database and the front-end talks to the API. • Va...

I’m ready to turn my concept for a dedicated social-media Android app into a fully functioning product. The project is strictly mobile app development for the Android platform—no iOS component is planned at this stage—so your experience with Kotlin or Java, Android Studio, Firebase (or an equivalent real-time back end), and clean Material Design guidelines will be critical. Core idea The app should allow users to create profiles, share posts (text, images, short video), follow others, and receive real-time notifications. Think lightweight, fast, and intuitive rather than a bloated “all-in-one” network. A smooth onboarding flow, secure authentication, and an easily scrollable home feed are my immediate priorities; messaging and advanced discovery featur...

I’m wrapping up a secure communication app built on a Java Spring Boot back-end with a React front-end and a companion Android client. The remaining work is focused on three areas: • Razorpay gateway: hook up the new API keys, route payments through the existing purchase flow, and return clean success / failure callbacks to both the mobile and web layers. • Code clean-up: identify and squash the lingering bugs that block a production build. Most issues have already been isolated in the repo and just need solid fixes and regression checks. • Google Play closed testing: run the mandatory 14-day closed test track, concentrating on performance.

My application relies on Apache PDFBox for generating and displaying PDFs, but the current build renders pages with an incorrect layout— it renders over other components in user interface. I need a developer who knows the internals of PDFBox, its Renderer (PDPageContentStream, PageDrawer, etc.), and the Java graphics pipeline to identify and patch the root cause of this layout problem. The problems is related to -method. It may be reproduced by adding a JSplitpane into a JFrame, then rendering to the left component. It renders over the right component, too. It is wrong. It also relates to PageDrawer and its setClip() -method. Even if we apply the initial clip, it still renders wrong, see code below. AffineTransform at = (); ();

Visual style: think classic casino—rich greens, polished brass, crisp typography—rather than minimalist or futuristic. I’m happy to provide reference tables, but I’m counting on you to capture that familiar Las Vegas feel. Core build expectations • Responsive UI built once and shared across Android (Java/Kotlin or Unity/Flutter) and Web (WebGL or HTML5/JS) • Clean architecture that separates game logic from presentation to keep future updates painless • Player wallet with deposit, wager, win, and history tracking, all guarded against common exploits • Optional admin back-office: view wagers, adjust balances, set RTP, and pull reports ...

I need a skilled Android developer to transform my concept into a fully functional, Play-Store-ready application.
