Can I integrate rocket chat inside an existing android app built in native code ?

[everestbis]

I want integration into my existing app. Is it possible? How difficult will it be?

If you only want the chat part use webview which works.

Natively there is no support and the app made in react native does not have reusable components to be used in other apps.
