Great News! This app supports Android 16 (SDK 36).

Support Microsoft Fluent 3D Emoji

My Firebase Chat app is purely developed using the native Android language. This is also known as a real-time chatting app between two people using the Firebase Database. The app has premium features that enhance the user experience. Users can send messages, files, and voice; be able to see online or offline status; type indicators; support emojis; and display date/time-wise messages. This app uses Firebase as a backend part. There was no use of any third-party admin panel or backend (PHP, Java, or any other framework). The source code is very easy to understand, customize, and re-skin the app for their personal use.

NOTE: Chats will be deleted on a weekly basis from the Demo APK. Just make sure to use your own Firebase account for those who purchase.
