Hi, I can build a complete Android chat app from scratch exactly as described, with clean architecture and production-ready quality. How I can help & strategy Build 1-to-1 real-time chat in Kotlin using Firebase / WebSockets (best option after discussion). Use MVVM + Clean Architecture for easy future upgrade to group chat. Instant message sync, offline caching, and auto-resync after airplane mode. Material Design UI, optimized for latest Android versions. Secure email authentication, unread count, last message preview. Thorough testing to ensure no crashes, no lint warnings. Deliver signed APK, full Android Studio project, README, and demo video. Experience 14+ years in Android app development Built chat, social, and real-time apps Strong experience with Kotlin, Firebase, REST/WebSockets Familiar with Play Store release & compliance Budget will be finalized in chat or call.

A CLEAN, REAL TIME ANDROID CHAT MVP BUILT FOR SCALE NOT A DEMO You’re looking for a production ready Android chat app that delivers instant messaging, survives offline states, and is architected cleanly so group chat can be added later. That’s a solid, technical MVP and exactly how we approach mobile products. At Plan D Studios, we’ve spent 12+ years building mobile apps, backend systems, and real-time applications used daily not prototypes that break under edge cases. How we’ll approach this: • Native Android app built in Kotlin using Material compliant UI • Real time messaging via a proven backend (Firebase or WebSocket-based API, chosen for instant sync + offline caching) • Email based authentication with clean session handling • Robust state management to handle rotation, airplane mode, and resync • Conversation list with unread counts and last message previews You’ll receive: • Android Studio project with clean, maintainable code • Signed release APK for Play Console • README covering architecture and build steps • Short screen recorded walkthrough This will be built as a scalable MVP no shortcuts, no over engineering. Would you prefer Firebase backed real-time sync or a custom API approach for future flexibility? Happy to discuss and move forward. Regards, Haider

Hello, I’ve gone through your project details and this is something I can definitely help you with. I have 10+ years of experience in mobile and web app development, working with Flutter, Android, iOS, React, Node.js, and APIs. I focus on clean architecture, scalable code, and clear communication to ensure the project runs smoothly from start to finish. I will first review your requirements for the Android chat app, suggest the best technical approach using Kotlin or Java, and then proceed with development while keeping you updated at every stage. Here is my portfolio: https://www.freelancer.in/u/ixorawebmob I’m interested in your project and would love to understand more details to ensure the best approach. Could you clarify: 1. Do you need this for mobile, web, or both? 2. Do you already have UI/UX designs or should we create them? 3. Will there be any third-party API or payment gateway integration? 4. What is your expected timeline for completion? 5. Are there any reference apps or websites you like? What features do you envision adding beyond the one-to-one chat functionality? Let’s discuss over chat! Regards, Arpit Jaiswal

Dear client, I have already developed chat app similar to whatsapp, I can show you the demo for testing, I have more than 9 years of exp in apps and web development.

@shanec35

Hello, I have carefully analyzed your requirements and recently built a real-time Android messaging application with one-to-one chat, email-based authentication, instant message sync, offline caching, and a clean Material-compliant UI in Kotlin. For your project, I will develop a complete Android chat app with secure authentication, real-time messaging via a reliable backend (WebSockets or Firebase), conversation lists with unread counts, and resilient state handling for rotation and offline scenarios. The codebase will be clean, well-structured, and ready for future group chat expansion, with a signed APK, README, and demo walkthrough provided. I am available to begin work immediately and am committed to delivering a high-quality, production-ready chat application in the shortest possible timeframe. Best regards, Elenilson

@sasaprogramer21

Hi, I can build this Android chat app from scratch with a clean Kotlin codebase and a real time messaging layer that stays reliable when the network is unstable. The first milestone will be one to one chat, but I will structure the data model and message routing so group chat can be added later without rewriting core screens. For backend, the most practical MVP option is Firebase Auth for email login plus Firestore for real time sync, offline caching, and unread counts, since it gives instant updates and handles reconnects well. If you prefer WebSockets, I can also deliver a lightweight Node or Python server, but Firebase will usually reach your acceptance criteria faster with fewer moving parts. On the app side, I will use Material design components, a conversation list with last message and unread badge, and a chat thread that supports instant delivery, local persistence, and automatic resync after airplane mode. State will be handled cleanly so rotation does not break active chats. You will receive an Android Studio project, a signed release APK, a short README with build steps and architecture, and a screen capture walkthrough showing registration, messaging, offline recovery, and unread counts working end to end. Best Alex

@logicstones

Hi, I have 5 years experience with android app development, recently I developed chat app with using Twilio, User can send Text, Voice message and user able to attach document like word, pdf or video also,. In your case you need just text messaging app with using of Firebase or Socket. If we use firebase database (Firestore) then we decrease the cost of server and it's management. In other case if we use sever my recommendation is Socket is best with notification also. Come to chat for details discussion, I'll start working immediately Regard: Abubakar

Hi there, You're asking for an Android chat app from scratch with one-to-one messaging, real-time delivery, offline caching, and email-based sign-in. I can handle this. I’ve shipped real-time chat apps in Kotlin with clean, maintainable code and production APKs. How I’d implement it: - Kotlin Android Studio project with MVVM and clean architecture - Email/password auth via Firebase Auth - Real-time sync through Firebase Firestore (or a WebSocket backend if you prefer) - Local cache and resilience to rotation/airplane mode with automatic resync - Modern Material UI, ready for future group chat Deliverables: a labeled Android Studio project, signed release APK, concise README, and a short screen-capture walkthrough. Availability: I can start immediately and target a 14-day window. Would you prefer Firebase (Firestore) for real-time chat and offline support, or a self-hosted WebSocket backend, and should we plan social logins later? Thanks,
