I have a HTML, CSS, JS webpage that needs three fixes. I believe this should be a simple project for someone who know website design and java. 1) Five slide shows on one webpage that I need the dot buttons to work/be highlighted in a different color when on that slide. The arrow sliders work and so do the dot buttons other than you can't see what dot the viewer is on. 2) The page also has an error on the menu, a portion of the menu shows highlighted section in blue. 3) The footer has spacing below it and is narrow as if in a table with a max-width.

My Android Studio Java app is still targeting API 34 and I need it fully brought up to API 36. Alongside the version bump, I want the codebase tightened so it runs more efficiently and the overall look refreshed with a modern theme. Scope • Update Gradle files, libraries and any deprecated calls so the project compiles cleanly against API 36, including new permission or foreground-service requirements. • Profile and refactor hotspots to shave unnecessary CPU / memory use and eliminate obvious jank. • Re-skin the app with a contemporary Material-based theme—colours, typography and styles—while preserving existing layouts and behaviours. Upgrade all the dependencies used in the project. Acceptance The upgraded project must build without warnings o...

...model must reason confidently in Python, JavaScript and Java, because those are the three stacks our teams use daily. You are free to orchestrate it with LangChain, OpenAI, Llama-index, or similar frameworks—whatever lets the prompts stay dynamic and the responses actionable. Desired flow 1. User enters a natural-language request in our IDE or chat UI. 2. Agent classifies the intent (generate, fix, or review). 3. It builds a structured prompt that injects file context, coding standards, and test output. 4. The large-language model produces a response. 5. Agent optionally writes changes to a feature branch or returns a diff for human approval. Acceptance criteria • Prompt templates adapt automatically to language (Python/JS/Java) and task type. •...

I want a full-featured Android live wallpaper built with LibGDX (Java) that drops users straight into a tranquil 3D koi pond. Multiple koi models should swim freely in real time while a convincing water-ripple shader reacts to both physics and touch.

Visual details to include • Floating leaves drifting on the surface. • Optional rain-drop particle effect I can toggle on or off. Settings panel The in-app settings screen is a priority. From there the user must be able to: 1. Resize fish individually or globally. 2. Increase or decrease rip...

I need a small Android proof-of-concept that launches the UIDAI FaceRD app via an explicit Intent, waits for the capture flow to finish, then receives the returned PID XML (biometric) data and renders it on-screen or writes it to logcat. Here is exactly what I expect: • An Android Studio project (Java or Kotlin) that targets any current SDK version compatible with FaceRD. • A signed, installable APK so I can test immediately. • On tap of a single button the app should:  1. Invoke with the correct action, extras and flags.  2. Handle the result in onActivityResult / ActivityResult API, extract the PID block, and show it clearly (raw XML is fine for the demo). Once I confirm the APK works, I will need the full, clean source code together wit...

...need a developer who can build a clean, stable Android application that lets users sit for fully-timed mock exams. The core of the project is the timer: each session must start, pause, resume, and submit automatically when time runs out, mirroring a real-world exam environment. For this first release I am only targeting Android, so please use a modern, well-supported tech stack (Kotlin or latest Java with Android Jetpack components). The UI should be lightweight and responsive, leaving room for future additions such as a question bank or analytics—but those extras are not in scope right now. Acceptance criteria • Home screen listing available mock tests • Start screen that clearly shows remaining time once the test begins • Automatic submission wh...

I need an Android-only time management app whose core purpose is to keep users on schedule through smart notifications and reminders. The flow is simple: a user sets a task, defines a deadline or ideal start time, and the app nudges them at just the right moments. You are free to choose the framework (native Kotlin/Java or a cross-platform option that still compiles cleanly for Android) as long as the final build is stable, responsive, and Play-Store-ready. I’ll want both an installable APK and full, well-commented source so I can iterate later—potentially adding task scheduling or full time-tracking modules down the road. Key expectations • Clean, modern UI that feels intuitive on current Android versions • Reliable foreground and background notifica...

I want to bring GitHub Copilot Agents into my own Java-based application so that they can automatically suggest code as developers type. My primary workspace is Visual Studio Code, and the core language throughout the project is Java, so the solution you give must play nicely with both. Here’s what I’m after: • A clear, working path to either connect directly to GitHub Copilot Agents from my application or to build equivalent custom agents that deliver the same real-time suggestion experience. • Code-level examples written in Java that demonstrate how the agent is invoked, passes context, and returns suggestions. • A brief walkthrough (video or written) that shows the integration running inside VS Code so I can replicate the setup on add...

...full-screen. As soon as the user taps the app icon, the video should start on its own—no play, pause, seek bar, or any other controls visible. After the video finishes, the app can simply close or loop; I’m open to whichever is quickest to implement. The MP4 file will be provided. Please package it inside the APK, so the app works offline with no additional downloads. Android Studio, Kotlin or Java, and the built-in VideoView or ExoPlayer are all fine as long as start-to-finish playback is seamless on Android 8.0 and above.

I’m building a secure, full-featured e-commerce solution that runs smoothly on iOS, Android, and the Web. The core stack can lean on Python for the API layer, with Java or C++ wherever high-performance modules make sense, but I’m open to a workflow you can justify that keeps code clean, well-documented, and easy to maintain. Core scope The first release must cover user account management (registration, login, password reset, profile editing) and end-to-end payment processing with major gateways. A responsive storefront, basic product catalogue, and an admin dashboard will round out the MVP. UX consistency across mobile and web is essential, and I’d like to see thoughtful error handling, secure data storage, and unit tests from day one. Deliverables for this mil...

I have an existing Android app that is stable but still very lean on features. The immediate goal is two-fold: first, roll out a new “upload” capability inside the app (users need to be able to select a f...securely to our backend); second, compile, sign, and publish the updated build to the Google Play Console so the change is live for all users. The current stack is Kotlin with standard Android Jetpack libraries; the backend is ready and exposes a REST endpoint for the upload, so the mobile side only needs to handle file selection, progress indication, and a simple success/fail response. If you prefer Java that’s fine—as long as the final APK/AAB plays nicely with our existing codebase. Deliverables • Updated versionCode / versionName and release n...

...summaries and printable reports at the click of a button.

Produce a backup file, uninstall the app, reinstall it, restore the backup, and see the same profile intact. I’m comfortable installing via APK or from the Play Console’s internal track if that is easier for you. Please build with modern Android Studio (Kotlin preferred, Java acceptable) and keep the UI clean—Material components are perfect. Let me know your estimated time...

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 &bull...

When the user opens the search help it should already be filtered by company code = ‘4000’, yet the user must still be free to change or extend that filter before choosing a value. Please reuse the necessary search help objects in SE11, bind them to the new context nodes, place the fields neatly on the screen This is a straight Web Dynpro ABAP task; no Java stack involved. If you have recent experience adding value help to custom fiel...

...schedule (we’ll fine-tune the exact interval together); second, run that stream through a lightweight data-processing routine before handing it back to me or posting it to an endpoint. The module should work on recent Android versions (API 26+), respect battery-saving rules, and keep running gracefully if the app is backgrounded or the device reboots. Kotlin is my preferred language, but solid Java is acceptable if that fits your style. Please package the deliverable so I can drop it straight into Android Studio: • Fully commented source code • A minimal sample activity/service showing it in action • A short README explaining any permissions, libraries, or Gradle tweaks If you already have ideas on efficient scheduling with WorkManager, fused-location...

...access from a web console. Zero-root, zero-popup, and zero-battery-drain are non-negotiable. How the platform should feel Think managed SaaS: multi-tenant, horizontally scalable, sub-second ingest for at least 10 000 concurrent devices, with an intuitive dashboard for live device views and remote commands. I am comfortable with Kubernetes, Terraform, and a micro-service approach (Go, Node, or Java), but you can propose an alternative stack as long as latency targets are met and the code base is clean, testable, and fully documented. Deliverables • Android 14 agent (Kotlin/NDK) that survives reboots, Play Protect scans, and OS upgrades, auto-updates itself, and streams app usage, keystrokes, and location in real time • Cloud backend (API, WebSocket, event queue) ...

...• A reliable, filterable transaction history for every user. • Tight, well-documented REST-based API integration so the two platforms stay perfectly in sync. The existing codebase is in core PHP with a MySQL backend, so familiarity with that stack is essential. All new endpoints should follow REST principles and be version-controlled on Git. The Android side should be built in Android Studio (Java or Kotlin—your choice, but keep the architecture modular and future-proof). Acceptance criteria 1. End-to-end payment flow tested in sandbox and live modes. 2. JWT-based login that passes penetration testing. 3. Transaction logs render <200 ms for 10,000 records. 4. Postman collection and inline PHPDoc for every new API method. 5. APK published to an int...

I have an existing code-base that needs to be compiled, configured, and deployed on a CentOS 7 server. The stack spans several languages (the repository mixes Java, Python, a bit of C++, and some PHP utility scripts) so I need someone comfortable moving through polyglot projects without breaking stride. （Developed independently using a non-Java language） The immediate goal is a repeatable deployment: building the artefacts, resolving library dependencies, wiring in systemd service files, and validating that everything starts cleanly after a reboot. You’ll work directly on my CentOS 7 instance (SSH access provided) and document any package or kernel-level tweaks you make so I can reproduce the setup on staging and production later. Because the code also ships to a s...
