As shown in the figure, the project requires me to complete the code (server) of Android set-top box, and then the ui needs to involve this key mapping, that is, the middle handle app is over the client (mobile phone), and then the key on the top needs to be mapped into the above numbers. The Delta Farce students who have just practiced this thing have no idea at all. Please give directions to the great gods. I have no idea at all how to write this. Thank you very much! !
So here comes the problem. Your problem is What? Do you want to be a client or a server?
