I want to launch an Android-only study app centred on live, collaborative learning rather than solo flashcards or static schedules. The core experience is a “virtual study room” where classmates can meet in real time, exchange ideas, and tackle material together. To make that happen, I need these three features working smoothly inside one intuitive interface: • Real-time chat for quick text exchanges and file links • Video conferencing so groups can see and hear one another without leaving the app • A shared whiteboard that lets everyone sketch formulas, mind-maps, or annotations together Clean UI/UX is important—students should be able to create or join a room in a tap, see who’s online, and move between chat, video, and the whiteboard without friction. I’m open to whichever libraries or services you prefer (Firebase, WebRTC, Agora, etc.) as long as performance is solid on mid-tier Android devices and all user data is handled securely. Deliver the complete Android Studio project with clear, commented code and a short setup guide so I can compile, test, and publish it to the Play Store.
