Socketer

For the Android version: https://sourceforge.net/projects/socketermobile/

Socketer is a simple tool that helps to debug sockets. It has both server and client functionality.

When a developer is developing features that requires sockets and network communication often it is really useful to be able to verify that their code is actually establishing the network connection and the code is actually handling data exchange over the network.

Socketer can open a server socket on a user chosen port and display the data receieved on that port. The client feature of Socketer can connect to hosts on the network on different ports and send data and also receieve data.
