    I want to ship a lean Android + iOS application that can 1) establish a Bluetooth Low Energy link to my peripheral and move data back and forth, and 2) instantly push out a user-defined BLE packet the moment the phone detects an incoming call. The BLE work is classic data-transfer: discover the device, pair, subscribe to characteristics, then read/write packets on demand. Stability in the background is critical; the link must stay alive (or reconnect quickly) when the screen is off. When a call arrives the app should listen to the system broadcast (Android) or CallKit/VoIP push workaround (iOS), pull the string the user previously defined, and write it over the existing BLE connection without visible delay.

    I want to bring a brand-new social networking idea to life on Android. The concept, user flows, and core screens are already sketched; now I need a developer who can turn them into a polished, production-ready app. Here’s the outline of what I’m after: • Full Android build in Kotlin (Java is acceptable if you have strong reasons). • Standard social features—secure sign-up/login, user profiles with photos, a simple post feed, likes/comments, and real-time chat or messaging. • Cloud-based back-end: I’m leaning toward Firebase for authentication, Firestore/Realtime Database, and push notifications, but I’m open to alternatives if you can justify them. • Clean architecture, modular code, and clear naming so another dev can jump in later if nee...

    Publish Flutter App Stores

    My Flutter app is finished and tested on my end; what’s left is to get it live on both Google Play and the Apple App Store. I already have active developer accounts for each platform and all listing assets—screenshots, icons, long/short descriptions—are prepared. I simply need someone who knows the submission pipelines inside-out to take the project across the finish line. Here’s what I’m looking for: • Build & sign the final release packages (AAB for Google Play, IPA for iOS) or validate the ones I provide. • Upload everything through Play Console and App Store Connect, filling in required metadata, privacy labels, content ratings and policy declarations. • Set up closed/internal testing: Google now mandates tester access prior to pu...

    I own a licensed copy of the Dooo Movie Streaming Android source code and now need it running live on Google Play. The current project refuses to compile because of dependency issues and an outdated SDK. Here’s what I need from you: • Open the project in Android Studio, upgrade it to the latest stable SDK/Gradle versions, and cleanly resolve every dependency conflict so the APK builds without warnings. • Configure package name, signing key, Firebase/Ad-mob (if present in the code), and any other runtime settings the template requires. • Run a full device/emulator test to confirm login, streaming, search, and push-notification flows all work exactly as in the template demo. • Generate release AAB/APK and guide me through—or directly handle—th...

    Integrate AdMob Native Ads
    6 días left
    Verificado

    I already have a live Flutter app and an active AdMob account. I now want Google AdMob Native (In-Feed) ads woven into my main listing feed, very similar to the way OLX sprinkles promotions between items. Here’s the flow I’m aiming for: after every five feed items a native ad should appear, matching the app’s current look and feel so users experience it as part of the content rather than a banner. I do not yet have the specific Native ad-unit ID, so I’ll need you to walk me through creating it in the AdMob console and wiring it up in code. The project is straightforward: plug the Google Mobile Ads SDK into my existing Flutter codebase (Dart), build a widget that pulls and renders the Native ad, place it in the list adapter, then verify that test ads show up reli...

    I’m ready to move forward with a project that pairs a full-featured Android app with a matching website. The core requirement both share is secure, reliable user authentication—think sign-up, login, password reset, and the usual account-management flows. Everything else about the product’s purpose, design language, and long-term roadmap is still flexible, so I’d like to refine those details together once you’re on board. I don’t have a fixed technology stack in mind; whether you prefer Kotlin in Android Studio, Flutter, React Native, or another modern framework on the mobile side—and Django, Laravel, Node.js, or something cloud-native on the web side—I’m open to your recommendations. What matters most is clean architecture, maintainabl...

    I need a straightforward mobile application that lets my team and I handle property inspections, repairs, and routine maintenance right from our phones on both iOS and Android. Each form should include Yes/No checkboxes, a comment area, and the option to attach photos so we can quickly document issues like a leaky faucet or damaged flooring. Real-time sync is essential: when one of us completes or edits a checklist, everyone else must see the update instantly. I’d like the data stored in the cloud—Firebase, AWS Amplify, or a similarly reliable backend—so nothing sits only on a single device. A second core feature is tenant-initiated work orders. Every unit should have a unique, scannable QR code. When tenants scan it, they’re taken to a simple screen (or a p...

    I need a clean, modern website where I can publish my dealership’s vehicles, attaching multiple photos and a video to every listing without fuss. The entire experience must feel seamless on a phone—image galleries should swipe smoothly, video playback must be instant, and buttons and forms have to fit comfortably on any small screen. Key points I care about: • A straightforward back-office that lets me add, edit or remove vehicles and drag-and-drop both photos and videos (common image formats + MP4 or YouTube/Vimeo links). • Lightning-fast, mobile-optimised front-end with clear calls to action for potential buyers. • Clean code and a framework or CMS that makes future updates easy for someone non-technical. • Final hand-off on my server, plus a quick ...

    I already own a full, unmodified copy of the WoWonder PHP script plus the matching Android Timeline App (a release from within the past year). All I need is an expert who has done this exact job before to turn that code into a Play-Store-ready build. Here is what has to happen: 1. Connect the Android source to my live WoWonder PHP site, including any custom server tweaks the API needs. 2. Reskin: swap in the new app name, splash screen, logo (I will supply the artwork) and adjust the primary colours so the interface matches the brand. 3. Change the package name to a unique identifier. 4. Produce a signed APK and an AAB bundle I can upload straight to Google Play. 5. Send brief notes on anything I must replicate if I update the code later. The server runs a customised configurati...
