Hello, I will build your Android app with a local SQL database in a simple and clean way from scratch. I can help shape the data models, the offline first logic, the CRUD operations, the UI flow, and the syncing rules if you plan to connect it to a server later. I always write clear and well organised code with tests and simple notes so anyone can understand how things work. We can review the full scope together and plan milestones that match your goals. I will prepare a modular Android setup, implement secure and efficient local SQL storage, refine the UI for a smooth user experience, optimise performance, add automated tests, and write a short guide explaining the main design choices. Looking forward to discussing further. Regards, Kamran.

As someone who has a vast amount of experience in mobile application development, your project truly stands out to me. You are in need of an Android app with local SQL integration and that is right up my alley. I am well-versed in both Java and Kotlin, which are the preferred languages you're looking for. My understanding of these languages, backed by my proficiency in front-end, back-end and database development means I can efficiently build your app from scratch while ensuring a seamless integration between your existing on-premise SQL server and the app. Another highlight of my skills is my attention to detail when it comes to security measures. I understand your app would be working within a local network; however, this doesn't mean taking network security lightly. With my knowledge, I can establish a secure connection to your server while also putting in place various fail-safes to handle any potential Wi-Fi interruptions. Moreover, trust is crucial when working on projects like this. I want you to feel confident that I am the perfect candidate for this project as I guarantee clean, well-commented source code that compiles without warnings in the latest Android Studio. The promised signed APK plus installation guide for your in-house MDM will be delivered adhering to the highest industry standards – all aimed at ensuring a smooth-running application. To put it simply, with me on board, you can expect a reliable and competent hand at every step of the way!

Hi, I have experience working with the exact skills required with project, including Android (Kotlin), local database handling, secure LAN integrations, and OTP SMS flows. I can deliver a robust, maintainable Android Studio project that meets your on-prem SQL Server requirements and offline resilience needs. Approach — how we will do this: I will build the app in Kotlin using MVVM and Room for local drafts and caching. For secure, reliable access to your on-prem SQL Server I recommend a small LAN adapter service (lightweight REST API) that runs inside your network; the app talks HTTPS to that service so credentials never leave the LAN. If you must connect directly, I can implement a secure JDBC/TDS client approach but it is less common and harder to secure on Android. The OTP flow will use your SMS gateway and follow your rules: code verification under 15 seconds and account lock after three failed attempts. I will include queueing and retry logic so task edits sync when Wi-Fi returns. Deliverables: full Android Studio project (Kotlin), signed APK, setup notes showing how to configure connection strings, ports and OTP endpoint, and a short handover. Note: The exact estimate will be shared after a detailed discussion. Thanks & Regards Abhishek

As an experienced mobile app developer with a keen expertise in Android Studio, Java, and SQL, I am thrilled to offer my skills for your project. Throughout my career I have crafted numerous apps that resonate well with the business requirements whilst ensuring top-notch performance and security. As a result, I can guarantee that your Android app will be a solid solution addressing your unique needs. Specifically, my ability to work with various databases, combined with my familiarity in managing local network connections will ensure seamless connectivity between your on-premise SQL server and the app. Not only will users efficiently create, assign, update and close tasks stored in the database but also encounter no confusion or trouble when handling any potential Wi-Fi disconnections. Furthermore, I understand the importance of smooth user experience when it comes to logging into applications. My knowledge in implementing OTP login systems will ensure that your phone-number based login system functions effectively and securely cutting down user lock-outs after failed attempts while assuring an optimal 15-second completion time. Rest assured, as a diligent coder, I will provide you with clean and well-commented code fulfilling all your acceptance criteria. We can collaborate effectively to make this nuanced project an absolute success.

Hi there, I see you're looking to build an Android app that uses a local SQL database for storing, retrieving, and managing data directly on the device. I have developed Android apps with SQLite and Room Database, including custom queries, offline first workflows, and clean UI integration, so I am confident I can deliver a stable, fast, and well structured solution tailored to your needs. 1. Should the app use plain SQLite or do you prefer Room Database for easier management and future scaling? 2. Do you want the app to sync data with an online server later, or should it stay fully offline? 3. Should the app include features like search, filters, exports, or user accounts? I would be glad to discuss the best plan for building this Android app so it runs smoothly and keeps data organized on the device. Let me know when you are available to talk. Best regards, Faizan
