Hey, I will deliver the Kotlin Android app — single-screen task list with server config, settings page for whitelisted numbers stored in Room, and the REST service with MySQL schema and import script. For the SMS dispatch, I will wire up ACTION_SENDTO with a BroadcastReceiver on the sent PendingIntent so the app can auto-detect delivery success or failure and pre-select the correct status button when you return — saving you manual taps on every task while still keeping full user control before the status is pushed back to the server. Questions: 1) For the backend, do you have a preference among Spring Boot, Node, or Flask — or should I go with whichever pairs fastest with your MySQL setup? 2) Should the whitelisted numbers also sync from the server, or strictly local entry only? Looking forward to discussing further. Best regards, Kamran

@chirgeo

Built this exact pattern before — Android app polling a REST backend, launching ACTION_SENDTO, then reporting status back without any background SMS permission headaches. 1. Should the app re-fetch the task list automatically on a timer, or only when you manually pull-to-refresh? This affects whether we need a foreground service or can keep it entirely activity-driven. 2. For the status callback, do tasks need to be marked idempotently (i.e., can you tap "Sent" twice without duplicating the record), or is the backend expected to handle that deduplication itself? 3. The whitelist screen lets you paste numbers manually — should the app silently filter out non-whitelisted destinations when tasks arrive from the server, or surface a visible warning so you know a task was skipped at fetch time rather than send time? 4. On the backend side, do you need multi-device support from day one (multiple phones hitting the same server, tasks claimed exclusively), or is this strictly single-device for now? Share the answers and I can lock down the data model and flow before writing a line of code.

Hi, Your workflow is clear: keep SMS testing lightweight, manual, and fully traceable without any background sending. I can build this so the app stays simple on the surface, but still gives you clean control over server sync, local whitelists, and delivery status updates. I’ve built Android apps in Kotlin with Retrofit/OkHttp, Room/SQLite, and REST-backed task flows, and I’d structure this prototype around two focused screens: one for server connection plus task handling, and one for local whitelist management. The Send action will open the system composer via ACTION_SENDTO exactly as you want, then the app will return Sent / Skipped / Failed back to your endpoint. For the backend, I can pair it with a compact Spring Boot service and a sample schema import so you can test immediately. I’ve shared an initial estimate based on your description, and once we go over a few technical or functional details, I’ll confirm the exact cost and delivery schedule. Would you prefer the backend to be Spring Boot for a more structured setup, or should I optimize for the fastest demo path with Node/Flask and SQLite? I’ll also include a clear README and setup guide so you can change the IP, run the server, and verify the full flow quickly. Looking forward to your reply so we can finalize the exact plan. Best regards, Asad

Hi, We can build this as a lightweight Kotlin Android test app + simple REST backend exactly as you described, focused on fast SMS workflow testing. Approach: • Android (Kotlin + Retrofit/OkHttp) • One main task screen + settings screen (server + whitelisted numbers) • Local storage via Room (simple + reliable) • SMS via ACTION_SENDTO (no background sending) • Status updates (Sent / Skipped / Failed) pushed via REST API Backend: • Simple Node.js (Express) or Spring Boot (your preference) • JSON endpoints for fetching tasks + updating status • MySQL or SQLite with a clean schema + import script Deliverables: • Full Android Studio project (clean README included) • REST API source code + DB schema • Setup guide (run server → set IP → test flow instantly) Regards Interconnect Team

Hi there, I’ve gone through your Android SMS Testing Utility spec and I’m confident I can deliver a lightweight Kotlin app that matches your workflow. I’ve built several small Android testing tools before, including Retrofit clients and local data stores, so I know how to keep this simple and fast. My approach is to implement a single settings screen for server and task list, use Retrofit to fetch pending messages, and launch the system SMS composer with ACTION_SENDTO, then push status updates via another REST call. The whitelist will live in a local SQLite/Room store, and I’ll provide a minimal backend with a clean, runnable Android Studio project, plus a quick import script for the schema and README for setup. Next step: I can start within 2 days and deliver a runnable prototype in about 5-7 days. Best regards,

@solutionsplayers

Hello, This is a clean Kotlin + REST workflow where the key is keeping the SMS flow fully manual while syncing task status reliably with your backend. I can build the Android app with Retrofit + Room for local whitelist storage, a simple task list UI, and ACTION_SENDTO SMS flow with status callbacks (Sent / Skipped / Failed) to your REST API. I have 7+ years of experience in Kotlin Android apps, REST APIs, Spring Boot/Node backends, and lightweight testing tools. I’ll also include a simple backend (Spring Boot or Flask) with JSON endpoints, MySQL/SQLite schema, and a setup guide so you can run everything quickly. Thanks! Best regards

Hi there, I’d be glad to help customize and improve your website end-to-end. I’m a full-stack engineer with strong experience across React, Vue, Angular, Node.js, Java/Spring Boot, REST APIs, databases, and AWS deployments, so I’m comfortable jumping into an existing codebase, understanding it quickly, and improving both the frontend and backend without disrupting current functionality. My usual approach is to start with a quick technical review of the project, identify the highest-impact improvements first, and then move into implementation focused on performance, responsiveness, maintainability, and overall UX. I’m also comfortable refining API structure, improving security, optimizing database queries, and streamlining deployments. A comparable project I worked on involved modernizing a production business platform where I refactored frontend components, optimized API performance, improved mobile responsiveness, reduced technical debt, and cleaned up AWS deployment workflows. The result was faster load times, smoother deployments, and a much easier codebase to maintain. For the first milestone, I’d estimate around 3–5 days for: • Full codebase review • Improvement roadmap • Initial UI/UX refinements • Performance and security improvements • Deployment updates I can start immediately and provide fast communication and feedback throughout the project. Kind regards.

✋ Hi there. I can build a lightweight Kotlin Android SMS testing app with REST API integration, local whitelist storage, task tracking, and a simple workflow focused on reliability and fast testing. ✔️ I have solid experience developing Android apps with Kotlin, Retrofit, OkHttp, Room database, REST APIs, and backend services using Spring Boot and Node.js. In a previous project, I developed an internal utility app that synced tasks from a backend server, handled local data storage, processed API responses, and tracked task statuses with stable error handling and clean architecture. ✔️ For your project, I will create a clean Android app with screens for server configuration, task management, and whitelist settings. The app will pull pending SMS tasks from your REST endpoint, launch the system SMS composer using ACTION_SENDTO, and send status updates back through API calls for Sent, Failed, or Skipped actions. ✔️ I can also build a lightweight backend service with JSON endpoints and MySQL or SQLite support, including sample schema files and setup documentation. The final delivery will include the full Android Studio project, backend source code, API setup guide, and testing instructions so you can run everything quickly. Let’s chat to discuss the preferred backend stack and prototype timeline. Best regards, Mykhaylo

@edwarddzi8f

Hi! I can help you with this SMS testing utility. This is right in my wheelhouse since I've been building Kotlin Android apps for over 10 years now. The flow you described is clean and well thought out. Retrofit for pulling pending tasks, ACTION_SENDTO so there's no background SMS permission headaches, Room for the whitelisted numbers, and a simple status callback endpoint. I'd go with Spring Boot for the backend since it pairs naturally with the Kotlin side and keeps the codebase consistent. I'm Edward and I've built similar task-driven utility apps before. The scope is tight enough that I can get you a working prototype fast. Let me know if you want to discuss the details.
