MultiStream is made for accessing multiple streaming platforms at the same place Watch, search, and get content from various streaming platforms like twitch, mixer. Application uses MVVM architecture. It has over 10 custom modules including many custom views and viewgroups, livestream/video player with chat, pagination, search, emoticons, navigation drawer, auth modules. One of the goals was to write reusable code because application combines multiple apis and platforms which essentially have similar purposes. Also it has a lot of unique UI/UX elements such as beautiful custom views, powerful animations, gestures. Application performs intensive work so there I'd had to use a lot of functional programming, coroutines channels and flows for handling over 100k users in chat while watching high quality livestream at the same time.
