9. Milestone 1

10. 1.Each user should select and enter a unique username, which will be used by the server to distinguish between different users (connections). If a user selects a username which has already been selected by a previous user, the server should send back a message indicating that this is a duplicate username.

11. Milestone 1 1.Each user should select and enter a unique username, which will be used by the server to distinguish between different users (connections). If a user selects a username which has already been selected by a previous user, the server should send back a message indicating that this is a duplicate username. 2.After a user has selected a valid username, all usernames of all other online users should be displayed. For instance, if there are 4 online users, their usernames should be displayed as follows: Player 1Player 2 Player 3Player 4

If a user selects a username which has already been selected by a previous user, the server should send back a message indicating that this is a duplicate username. 2.After a user has selected a valid username, all usernames of all OTHER online users should be displayed using ListView, GridView, or TableLayout. For instance, if there are 4 online users, their usernames should be displayed as follows: 3.If a user clicks on another user’s username, an invitation should be sent, and the recipient should be able to either accept or reject the invitation. Player 1Player 2 Player 3Player 4

13. Milestone 1 4.Suppose that there are 3 online users called A, B and C. Now assume that A has sent an invitation to B, and that B has accepted this invitation. If C then tries to send an invitation to B, the server should inform C that this is not possible, as B has already accepted an invitation from A.

If C then tries to send an invitation to B, the server should inform C that this is not possible, as B has already accepted an invitation from A. 5.For testing purposes, open 3 emulators and ensure that all of the above mentioned conditions are functioning correctly.
