How deepakkasera/friendschatapp works
FriendlyChatApp is an Android realtime chat client for text and photo messages. The main activity initializes Firebase, handles sign-in and user input, uploads selected photos, writes messages, and listens for new messages; the adapter renders each message in the list. The README describes cross-platform realtime use, while the excerpts show Firebase-backed storage and authentication. Source inspection is limited to the provided excerpts, so undocumented backend behavior and some lifecycle details are not expanded.
