I want to implement a real time update of a Text for example between the Users of an android app. For example 5 friends have this app and ONLY the 5 of them will communicate between them.
Is this somehow possible without having to run my own server?
I wanted to use Firebase but it seems that there is no extension for this. I found a post regarding Firebase support request but it doesn't seem active.
Is there something similar to Firebase i can use or the private server is one way solution?
