Java Android Native App with duo architechture upgrade & edit

I have a 10 page java app that utilizes a dedicated backend server to run it's services. When the app was originally written it connected to the dedi server via a combination of ssh/rpc sockets to gain access to the dedi's cli and execute cmds on the active service. Recently, I decided to update to a websocket based connection to access the dedi server cli and make other updates. A team started the process of updating but we had to part ways before they finished. I wanted you to come in, look at the source, and we can go over, point-by-point. The changes we see have been made and the ones still left to be done. 99% of the work is on the front end app only. You will also implement a plugin to create a device token for firebase. All firebase functionality will be handled by my backend developer. You will only be required to provide the device token and receive/display notifications.We utilize a mysql db for authentication in the app which has a couple api's that need updating to satisfy the needs of this update (api updates will be handled by my developer). I would like to hold a meeting so we can share screen and look at the source and screens and we can find the rpc calls remaining and discuss other changes.

A demonstration video will be provided. Successful completion of this small task will give first bid rights to the next project which is larger.
