Overview. We will look at four network applications, written completely from scratch in Java. Each of these applications use the client-server paradigm, which we discussed earlier (the server passively waits for a connection, a client connects, the two parties exchange information, and finally the parties close their connection):. These Java examples will use TCP/IP.

In this Android Client-Server Using Sockets post series we will be focusing on server side implementation. We have covered Client side implementation in our previous post “Android Client-Server Using Sockets – Client Implementation” Android has very vast set of libraries so that users can implement innovative ideas with provided libraries. It is very easy to create server in android.

The basic mechanisms of client-server setup are: A client app send a request to a server app. The server app returns a reply. Some of the basic data communications between client and server are: File transfer – sends name and gets a file. Web page – sends url and gets a page. Echo – sends a message.

One part of this task is authentication (which can be done also via certificates) and another part is the encrypted connection that protects the communication between server and client. cert/) db2.
