Hi Ananiya, Just finished a similar project - Developing an Android app with QR Code scanning functionality. I'm confident that my team and I are the perfect fit for your Android QR Code Data Logger project. With multiple 5-star reviews on similar projects, you can trust that we'll deliver high-quality work. Our team has extensive experience in Android app development, with expertise in building efficient and user-friendly apps that meet our clients' needs. We'll use Kotlin as the preferred language for this project and rely on the Google ML Kit for QR code scanning. Our app will handle runtime camera-permission smoothly and compile seamlessly in the latest Android Studio. We'll also ensure that the source code is well-commented and the APK is release-ready. We'll deliver the project as per your requirements, including a complete source code, signed release-ready APK, and a one-page README explaining the build steps, used libraries, and data storage. I understand that you want to test the app by installing the APK, scanning several codes, and confirming that each decoded string appears instantly and persists in the local history after the app restarts. We'll ensure that this is done and more. The worst that can happen is you walk away with a free consultation to discuss your project in more detail. I'd love to chat about your Android QR Code Data Logger project and explore how we can help. Best regards, Chris | Lead Developer | Novatech

Hi, I’ve gone through your requirement and it’s very clear. I can build exactly what you need — a lightweight Android app that opens the camera, scans a QR code, instantly displays the decoded text, and stores it locally for later use. After each scan: The decoded text will be shown immediately on screen The text will be saved locally using Room / SQLite An SMS will be sent automatically using the scanned text and the phone number present in the QR content The scan will appear in a searchable history screen, even after the app is restarted No external sharing, no URL launching — just clean, reliable capture and storage. Implementation approach: QR Scanner: Google ML Kit or ZXing Camera handling: CameraX Local storage: Room (SQLite) PDF generation from stored scan data Proper runtime permission handling for Camera and SMS Minimum Android version: Android 8 (API 26+) Clean, readable Kotlin codebase (Java if preferred) Deliverables: Complete, well-commented source code Signed, release-ready APK A short README explaining build steps, libraries used, and data storage Testing: You’ll be able to install the APK, scan multiple QR codes, restart the app, and confirm: Each scan appears instantly All scans persist in local history Search works correctly I focus on building simple, maintainable Android apps that do exactly what’s required, without unnecessary complexity. I can complete this within your budget Happy to discuss any small adjustments before starting. Thanks, Radhika

@Roneldb

Good Day, I have carefully reviewed your requirements for a lightweight Android app focused on QR code scanning, reliable text capture, and local storage with immediate on-screen display. The project requires a clean Kotlin or Java codebase targeting API 26+, with efficient runtime permission handling and smooth compilation in the latest Android Studio, delivering source code, a signed APK, and concise documentation. To implement this, we can integrate Google ML Kit or ZXing for robust QR scanning. Data persistence can be managed using Room for efficient local storage and easy querying. Generating PDFs from stored text will ensure easy offline access. Alternative approaches include using plain SQLite or exploring Android’s WorkManager for message sending automation. I am committed to flexible revisions, prompt communication, and addressing any questions you may have throughout the project. I look forward to collaborating and delivering a reliable, polished application that meets your expectations. Regards Ronel

@gurmukhs8

Well, your requirements are very clear: offline QR scanning, Room-based persistence, PDF export, and SMS per scan, and that’s exactly the kind of focused Android work I handle end-to-end. 1- Should the SMS be sent automatically after each scan to the number in the QR text, or should the user confirm before sending? 2- Is the QR data always plain text with a phone number, and do you want PDF per scan or one combined PDF for the full history? 3- Any preference for Kotlin vs Java, and should all scan data remain strictly local with no cloud backup for now? Once the requirements are clear, I’ll first set up a clean Kotlin-based Android project with proper camera permissions and QR scanning using ML Kit or ZXing.I’ll store each decoded scan locally using Room, show it instantly on-screen, trigger SMS safely, and maintain a fast searchable history with PDF export.I’ll keep the app lightweight, offline-first, well-tested on real devices, and I’m open to suggestions if you want any flow or feature refined. Let’s connect and walk through the requirements in detail so I can align the QR scan flow, local storage, SMS handling, and PDF output exactly to your expectations. Please don’t judge my experience based only on this new profile ..I’ve successfully delivered similar Android projects on Upwork and can share references if needed. Let me know a time that works for you, and I’ll adjust accordingly.
