 # Kaazing Android WebSocket Echo Tutorial
 
-This tutorial shows how Android application can communicate over the web with an `echo` service running within Kaazing WebSocket Gateway using Kaazing Java WebSocket Client library. The application sends text messages to the `echo` service over WebSocket.
-The `echo` service, running inside the Kaazing WebSocket Gateway, reflects back the message that is received by the Android application. 
+This Android app communicates with a remote `Echo` service hosted by Kaazing WebSocket Gateway. The app sends and receives text messages with the `Echo` service over WebSocket.
