+                This sample demonstrates how to use the ConnectivityManager to determine if you have
+                a network connection, and if so, what type of connection it is.
+                \n\nA "NetworkInfo" object is retrieved from the ConnectivityManager, which contains information
+                on the active connection, and then the connection type is printed to an on-screen console.
