Android Question Peer To Peer chat

[James05]

Hello,

Newbie here. Is it possible to make a peer to peer chat applicstion where users exchange messages on different networks?

If so, can somebody give me a hint on what libraries & protocols I should use?

The devices need to somehow connect to each other. If they are not in the same network and are not physically close to each other then you will need to use an external internet server.

Thanks, I will look into it. In your opinion, what is the best database for a cross-platform chat app?

The question is too vague...
