    I need a lightweight Android Accessibility Service that silently accepts incoming ride requests inside the Ola Driver app. The service must: • Detect the ride-request pop-up and perform a single, human-like tap on the accept button. Tap coordinates and delay have to vary a little on every press so the behaviour looks organic. • Stay active only while the Ola Driver app is in the foreground and I am online; it should pause automatically when I switch the app offline. • Run unobtrusively in the background, start on boot if possible, and ask for the minimum permissions required. Deliverables • Installable APK plus complete Android Studio project with clean, well-commented source. • Step-by-step guide showing how to enable and test the Accessibility Service. ...

    I need a single Android application that seamlessly blends three experiences: a full-featured shopping portal, a robust bill-payment hub, and a stored-value wallet. For the wallet, real money movement is essential. Users must be able to add funds straight from their bank accounts and through a payment-gateway top-up flow, see every credit or debit in a clear transaction history, and send money to other users instantly. The shopping side should feel like any modern e-commerce app: a browsable product catalog, an intuitive cart (with quantity edits and promo-code entry), and a wishlist that persists across sessions so shoppers can save items for later. When a user checks out, the wallet balance should appear as a payment option alongside any external gateways. Bill payments should f...

    I want a complete Chess game built in Android Studio with clean, well-commented code so that I can study and extend it later. The project must implement every official rule of chess: legal piece movement, check and checkmate recognition, castling (both sides), pawn promotion to any major piece, and the ability to undo the last move. The look and feel should follow a classic user-interface style, pairing naturally with a traditional wooden board and pieces. While I prefer that timeless aesthetic, the architecture should be flexible enough that I can swap in alternative themes later if I choose. Gameplay has to feel smooth and professional. Fast, responsive touch controls are essential, and performance should remain solid even on older Android devices. Subtle animations are welcome as lo...

    I need an experienced developer to take a deep look at my Android application and the server calls that power it, then tune both sides so the user experience feels instant and light. Right now the app shows occasional frame drops, long cold-start times, and higher-than-expected RAM usage. I want measurable gains in speed and responsiveness without sacrificing stability, plus a clear reduction in memory footprint. What you’ll actually do • Profile the APK with Android Studio Profiler, Systrace, and (if you prefer) tools such as Firebase Performance or LeakCanary to isolate hot paths and leaks. • Review the API layer and suggest tweaks—batching, caching, pagination, or server-side query changes—so network latency no longer blocks the UI thread. • Refac...

    I need a single code-base application that lets companies who move oversize loads find and book escort drivers quickly. The priority is a smooth, real-time chat that connects the load owner with available escorts the moment a request is posted. The conversation thread should stay synced across iOS, Android, and a responsive web portal, so whichever device people pick up, the same history, files, and read receipts appear instantly. Alongside chat, a lightweight map is required. It only has to display origin, destination, and the suggested route; live traffic layers or GPS tracking can wait for a later phase. Think of it as a visual aid inside the chat window that both sides can reference while they negotiate. Key screens I expect: • Escort marketplace where drivers list their availa...

Because I’m interested in both fixing the bug and improving the core method, you will be free to refactor, recalibrate, or even redesign parts of the analysis pipeline provided the camera capture and colour-extraction steps remain intact.

The first release is deliberately slim: the core flow should take a customer from selecting a package, through a secure checkout, to a confirmation screen—no social features or in-app chat at this stage. What I need from you is an Android-native build (Kotlin or Java) with fully tested payment integration. I am open to Stripe, Razorpay, PayPal, or another gateway you prefer, as long as it supports one-time charges and handles common payment errors gracefully. A clean, intuitive UI, basic booking logic, and a small admin settings area for toggling prices or availability will round out the MVP. To wrap things up smoothly, please provide:...

    My field crews often work in areas with little or no connectivity, yet they still have to capture photos and short videos, tag them with notes, and move on. I need a native Android application that lets them work exactly as if they were online, then quietly and predictably syncs everything the moment a signal returns. Here is what matters most to me: • True offline-first architecture – every action must be stored locally (including high-resolution images and short videos) and never be blocked by a missing connection. • A reliable, persistent sync queue that can survive an app crash or a forced reboot. The queue should retry automatically with exponential back-off and surface any unrecoverable errors for manual intervention. • Intelligent conflict resolution &ndas...

    Custom GPS Tracker App

    I own the GPS tracker shown here: and have full access to its open-source firmware and communication protocol. I now need a polished mobile application, built once and shipped natively to both iOS and Android, that talks directly to this device and brings the data to life for end-users. Core functionality must include: • Real-time location updates on a smooth map view. • Configurable geofences that trigger push notifications the moment the tracker crosses a boundary. • A clean, scrollable history screen where users can replay routes for any chosen date and time range. Users will sign in with a simple username-and-password flow, so the app should ship with a lightweight authentication backend (Firebase Auth, Supabase, or a similar plug-and-play service is fine). All ...

    I need an end-to-end Android finance application that is bullet-proof from a security and compliance standpoint. The core flow begins with a smooth, secure onboarding experience that performs Basic KYC checks; I’ll supply the exact compliance rules and the API endpoints you should call. Once a user is verified, the app must display real-time account balances and a transaction history that includes fast search and filter options. If you’d like to suggest richer breakdowns or export features later, I’m open, but they’re not part of the first release. Security requirements are strict: data must be encrypted at rest and in transit, all sensitive actions gated by biometric login (Android BiometricPrompt), and every meaningful event captured in an immutable audit trai...

    I have a batch of Android tablets that refuse to complete their normal software update because I can no longer sign in to start the process. I need a freelancer who can walk me through—or remotely carry out—a full software update so each device is running the latest version it supports and all security patches are applied. The work will be finished once every tablet can: • sign in without errors • download and install the current official system update • reboot and operate normally afterward If you have proven experience recovering locked-out devices and pushing OS or firmware updates, I’m ready to get started right away.

    I want to turn the quirky idea of a “Chicken Road Prediction Bot” into a fully working Android app. The concept is simple: feed the app either live video or pre-recorded movement data of chickens near a roadway and have it predict if, when, and where a bird will step onto the road. The platform is strictly mobile and Android is the only operating system I need supported. Here’s what I expect: • A lightweight Android application (Kotlin or Java) with a clean UI that shows a camera preview or data feed and overlays the real-time prediction. • An on-device model—TensorFlow Lite, PyTorch Mobile, or a comparable framework—that can run offline and outputs a confidence score plus an ETA for the crossing. • A simple stats panel logging every pr...
