Answer 1

Here is logic which you can apply.

1. You have to store a flag in your android application which will maintenance login status. once you move from login screen to chat screen, update your flag to true. so now you know that you have already login and you are in chat screen where you will have socket object. please save that socket object.
2. Now when you press the back button then you should know that you have already login by a flag which you have saved so auto redirects the user to chat screen. as you already have socket.io object, you can do communication same as before.

I hope this answer helps you and solve your problem.
