💬 Java Android Messenger

Java Android Messenger (app name: Social Chat) is an AI-powered chat app for Android, built with Java. Every message you send is forwarded to Google's Gemini API, and the reply is shown as a chat bubble — with the full conversation history persisted locally in a SQLite database.

✨ Features

✅ Gemini AI replies: Every message is sent to Google's Gemini API and answered in real time. ✅ Persistent history: All messages are stored locally in a SQLite database and reloaded on launch. ✅ Chat-style UI: User and bot messages are rendered as distinct, rounded message bubbles. ✅ Clear conversation: Wipe the entire chat history with a single confirmation dialog. ✅ Smooth animations: Input field and send button use subtle scale/overshoot animations, and new messages fade and slide in. ✅ Automatic retries: Failed requests due to rate limiting are retried automatically before surfacing an error.
