Project description:
"I am building a social-media application and I now need a robust instant-messaging feature added to the existing Android codebase.

What I want right now
• One-to-one and group chat with text, emoji, and basic file attachment support.
• Real-time delivery and read indicators using a reliable service such as Firebase Cloud Messaging or a comparable solution.
• Secure message storage (end-to-end or server-side encryption, depending on your recommended architecture).
• Clean, Material-compliant UI components that slot naturally into my current screens.
• Clear documentation so future updates—like photo/video sharing or push notifications—can be integrated smoothly.

You should be comfortable refactoring Kotlin/Java code, setting up scalable back-end messaging (Firebase, [login to view URL], or a tech you propose), and handing over concise build instructions. A quick call to walk through the project structure and hand-off will be part of the final delivery." (client-provided description)
