I have an app, some bugs need to fixed.

PROBLEM: - Uploading app to Amazon Appstore - Getting error: "AAB2 bundle currently supports no devices" - AAB1 works fine (supports 12 Fire Tablets + 2 Fire TV) - AAB2 bundle is being rejected WHAT I NEED: - Fix ...currently supports no devices" - AAB1 works fine (supports 12 Fire Tablets + 2 Fire TV) - AAB2 bundle is being rejected WHAT I NEED: - Fix to generate single universal AAB with ARM support only - Ensure app supports all Fire Tablets and Fire TV devices - Remove x86/x86_64 architectures that Fire devices don't need - Test build to confirm it works TECHNICAL DETAILS: - Flutter app with Kotlin DSL () - Need to configure NDK abiFilters correctly - Currently using default Flutter build settings - App already has proper signing and ProGuard configured

...the phone begins broadcasting its GPS location. Once the route is finished, they tap “End Trip” and tracking stops. • Only two roles are needed for the first release—Students/Parents (view-only) and Drivers (share location). A future administrator role could be added later, so structure the code with that in mind. I am comfortable with either a shared-code approach (Flutter, React Native, Kotlin Multiplatform) or native builds, as long as both stores are covered and the Google Maps SDK is the mapping backbone. Clean architecture, clear separation of concerns, and well-commented code are essential because I’d like you to walk me through the logic afterward. Plan on a brief hand-off session or recorded walkthrough so I understand how the GPS publis...

...Android. Fokusnya adalah pengembangan aplikasi, bukan web atau desain grafis, sehingga keahlian utama Anda harus mencakup pembuatan game mobile. Gambaran singkat: • Jenis aplikasi: permainan kasual—game‐play cukup sederhana agar ringan dijalankan di berbagai perangkat Android. • Target platform: Android (versi 8.0 Oreo ke atas diutamakan). • Teknologi: saya terbuka pada Unity, Godot, atau native Kotlin/Java—silakan pilih yang paling efisien untuk performa dan pemeliharaan.

If you have experience with BLE firmware, handwriting recognition libraries, and cross-platform mobile development tools such as Flutter, React Native, Swift or Kotlin, I’m ready ...

...business logic as possible, then reshape it for a smooth mobile flow. The Android build must preserve every live feature—gameplay, wallet handling, real-time matchmaking, authentication, in-game chat, and anything else users already enjoy on the web—while also feeling truly native (push notifications, back-button behaviour, Play-Store-ready signing, etc.). I am happy to consider React Native, Kotlin, Flutter or another approach if it lets us: • call my current REST/WebSocket endpoints with minimal refactor • keep animations and turn logic perfectly in sync across platforms • handle real-money transactions securely and pass Google Play policy checks Deliverables: 1. Source code with clear build instructions 2. A signed, release-ready APK/AAB...

1. Core Framework: Platform: 100% Native Android (Kotlin or Java). Strictly NO WebView or Hybrid frameworks. Database: Real-time synchronization with a secure web-based Admin Panel. 2. Task & AdMob Integration (Full Security): Flow: User clicks Task -> Trigger AdMob Interstitial/Rewarded Ad -> Redirect to YouTube/TikTok/FB -> Task Verified. Server-Side Callbacks: Use server-side validation for AdMob rewards to prevent ad-skipping hacks. Frequency Capping: Strict limit of 4 ads per device/day to protect AdMob account health. 3. 6-Level Referral & Salary Logic: Architecture: Automated server-side tracking for a 6-level referral hierarchy.

...statistics so organisers can review past performances. Because most users will expect a quick sign-up flow, social-media login options (Google, Facebook, Twitter) need to be baked in from the start. I also need a lightweight in-app payment gateway so teams can pay entry fees or unlock premium brackets without leaving the platform. Deliverables • Production-ready Android APK and source code (Kotlin or Java). • An admin panel (web or in-app) where I can approve teams, edit match times, and view aggregated stats. • A short demo video or live walkthrough showcasing team creation, scheduling, stat tracking, social login, and a test payment flow. • Clean, well-commented code and a concise setup guide so I can compile and publish future updates myself.

The goal is to build a lightweight Android utility focused on task management. Core capability centres on notifications and reminders—covering everyday to-dos as well as specialised payment nudges and simple order-processing follow-ups—delivered reliably on Android 8.0+ devices. Scope of work • Create the full Android application in Kotlin (Java is acceptable if strongly preferred) with Android Studio. • Design clean Material-compliant screens for adding, editing and browsing tasks. • Persist data locally with Room; structure the code so a future cloud sync (e.g. Firebase) can slot in without major refactoring. • Implement a reminder engine that schedules push notifications, survives device reboots and handles recurring events such as monthly...

...lets me update trend data, brand catalogs and style rules without redeploying the app. Technology expectations The recommendation layer can be built with Python (TensorFlow / PyTorch) or a similarly capable stack, and computer-vision models (e.g., OpenCV, Mediapipe) will be needed to validate measurements from photos if users choose that option. The mobile front‐end may be native (Swift / Kotlin) or React Native / Flutter as long as performance remains smooth. Cloud hosting on AWS, GCP or Azure is fine; I’ll provide the keys.

I’m ready to have a brand-new feature built from scratch for my mobile application, and the entire codebase needs to be written in pure Java. Performance, clean architecture, and clear inline documentation are non-negotiable because this module will slot straight into an existing codebase that already follows solid, maintainable practices. Here’s what I need from you: • A concise outline of your technical approach—how you’ll structure the code, the patterns or libraries you prefer, and the way you’ll keep the footprint lightweight on a mobile device. • A short overview of your relevant Java mobile experience, especially any instances where you created a feature end-to-end rather than extending existing code. • Your best estimate of the cale...

I need the Android proctoring SDK I already built in Kotlin ported to iOS using pure Swift so it can be dropped into any React Native-based LMS or quiz app. Core purpose The SDK must deliver full-featured exam proctoring: it authenticates the test-taker (biometric login), records periodic face snapshots and screen images, and monitors audio, screen activity, and user presence to flag anyone who leaves the exam environment. Scope of work You will mirror every capability of the existing Android library; I will share the full Kotlin source and its React Native bridge as a reference. The iOS package must expose the same React Native interface so current JavaScript calls remain unchanged. Key feature set • Biometric user authentication via Face ID / Touch ID •...

I need a small, reliable utility that runs on both iOS and ...possible—no extra buttons, no manual entry steps beyond my confirmation tap. The build must pass App Store and Google Play requirements, so remember permissions for Photos/Screenshots and Contacts access, and keep processing on-device (no external servers). Deliverables • Production-ready apps for iOS and Android • Complete, well-commented source code (Swift/SwiftUI or Objective-C for iOS, Kotlin/Java for Android—use what you are fastest with) • A brief README describing project setup, required entitlements and how to compile or archive the release builds I’ll test by taking screenshots that contain single and multiple numbers; the app should behave exactly as described above. Lo...

I’m open to your preferred tech stack, though Kotlin + modern Android architecture components make sense. Clean, maintainable code, a straightforward admin console (web or Firebase), and clear hand-over documentation are part of the job. If you’ve shipped commerce or healthcare-style apps with OTP login, push notifications, and branch-aware inve...

I want to bring a dedicated Android e-commerce application from concept to Google Play. The core of the build is straightforward: customers must be able to browse products, add items to a cart, and check out smoothly—but the standout requirement is a robust push-notification system that keeps shoppers updated on promotions, order status, and cart reminders in real time. My priority stack is Kotlin with Android Studio, though I am open to proven cross-compatible libraries where it makes sense. Payment processing, user profiles, and basic analytics are already budgeted for the next phase, so please set up the project architecture with future modules in mind. Deliverables: • Production-ready APK plus signed AAB for store release • Complete, well-commented source cod...

...customer-facing app, I also require: a lightweight driver/delivery app so couriers can receive orders, update statuses in real time, and navigate to addresses; plus a secure admin panel where I can manage inventory, prices, users, promotions, and review analytics. To keep everything maintainable, please use a modern cross-platform stack (Flutter, React Native, or a solid native duo of Swift and Kotlin—your call, just explain your choice) connected to a scalable backend with REST or GraphQL APIs. Push notifications, basic order tracking, and App Store/Google Play submission support are expected. Deliverables • Source code for customer, delivery, and admin apps • Ready-to-deploy backend with documentation • UI/UX assets and build files • Live...

I’m building a fully native mobile application that lets drivers book automotive services The core flow is simple: users create an account (email, phone, or social login),check real-time availability, reserve a time, then pay securely without ever leaving the app. Both iOS and Android need to feel identical in look and speed, so I’m expecting Swift/SwiftUI on the Apple side and Kotlin with Jetpack on Android, backed by a single REST or GraphQL API. South African gateway must handle payments, supporting saved cards and one-touch checkout via Credit Card (VISA) or selected electronic transfers as well as PayPal etc. Please show me past work that demonstrates: • native builds (no hybrid wrappers) • secure login implementation • a live payment ...

...bypass the VPN • Support for the following protocols or transport layers: ssh, ssl, udp, v2ray, and websocket • A menu of multiple server locations that I can expand later through simple JSON or similar remote config No in-app user-authentication flow is required; the build should assume pre-provisioned profiles or embedded credentials. Deliverables: 1. Clean, well-commented source code (/Kotlin or Java/) 2. Signed release builds ready for TestFlight and Google Play Internal Testing 3. Brief deployment guide covering server configuration files, protocol setup, and how to add new endpoints 4. One short video or screenshots that demonstrate kill switch and split tunneling working on an actual device If you have previously integrated v2ray or websocket trans...

...secure offline-viewing feature. The downloads must remain tied to each student’s login so that only authenticated users can view the files; once a user signs out, access to the stored videos should be revoked automatically. Because I am not sure what level of server or code access the institute can grant, the solution may involve: • Modifying the existing iOS (Swift/Objective-C) and Android (Kotlin/Java) apps to incorporate encrypted, device-bound storage or HLS with DRM. • Proposing lightweight server-side changes—perhaps token-based URLs or time-limited keys—so the institute’s current backend can authorize downloads without exposing raw files. • Implementing local logic that verifies the user’s credentials on every app launc...

I am building a utility-style Android application and need an experienced Kotlin developer to take it from concept to a stable, Play-ready release. The core of the job involves: • Designing clean, maintainable Kotlin code that follows Android best practices (MVVM, Jetpack components, coroutines). • Implementing a small feature set typical of tools apps—think background services, permission handling, and a concise, responsive UI built with XML or Jetpack Compose. • Integrating basic analytics and in-app settings so the user can customise the experience. • Connecting the app to a lightweight local data store (Room or DataStore) for persistence. • Packaging, signing, and preparing a release build that passes Google Play requirements. ...

...notifications, and lightweight rewards or gamification that keep people scrolling and sharing. Seamless social log-in, push-notification opt-ins, and in-app analytics are essential so I can track retention and tweak campaigns in near-real time. Because engagement is the metric that matters, every screen should encourage interaction. I’m open on the tech stack, but Flutter, React Native, or Swift/Kotlin natives are welcome as long as the final builds pass App Store / Google Play submission checks and integrate smoothly with Firebase or an equivalent back-end for auth, media storage, and event tracking. Acceptance criteria • iOS and Android builds compiled and installable • Clean, commented source code stored in Git • Basic UI/UX reflects modern social ...

...need noticeably faster load times, smooth in-app transitions, and an architecture that scales as the user base grows.

Acceptance criteria • Google Lighthouse performance score of 90+ on critical pages. • All new features pass security and role-permissi...

...WebView. • I have already experimented with various WebView settings—JavaScript, media playback flags, setMediaPlaybackRequiresUserGesture =false, etc.—but nothing has stopped the pause on “home” or “recent-apps” actions. • No alternative implementations (custom players, exo-player wrappers, or different WebView engines) are in place, What I need from you: 1. A working code solution (Java or Kotlin) that lets the video continue playing when the user switches apps or locks the screen. 2. Any required permissions, service code, or MediaSession / audio-focus handling clearly documented so I can integrate it quickly. 3. A short explanation of why this approach works and any limitations on specific Android versions. Please tes...

I’m building an Android-only application and need a clean, secure login flow that relies on one-time passwords sent strictly by SMS. Users will enter their phone number, receive the code, and gain access after successful verification—no usernames or emails involved. You’ll be responsible for wiring up the full authentication cycle, choosing a reliable SMS gateway, and writing the Android code (Kotlin or Java—your call) that: • accepts the phone number, • triggers the SMS OTP dispatch, • validates the returned code with sensible expiry and limited retries, • handles resend logic, and • stores / refreshes session tokens once the user is verified. Deliverables must include the documented source code, any backend or cloud fun...

...contacts. 2. From there they can dive deeper—update task status, pay an invoice through Stripe or Razorpay, or add notes to a contact, all while receiving push notifications powered by Firebase Cloud Messaging. 3. Admin tools (also inside the app) let me export reports in CSV or PDF and tweak basic settings without touching code. Tech-wise I’m comfortable if you lean on Android Studio with Kotlin or Java, Material 3 components, Room or Realm for offline storage, and a secure back-end of your choice (Firebase, Supabase, or a lightweight REST API). I need source code in a private Git repo, a signed release APK/AAB, and a brief hand-off video or document so I can publish future updates myself. Acceptance criteria • Tasks, invoices, and CRM modules function e...
