Android TCP server

I am trying to send a simple textual message to my android phone from my computer. The phone is on the same WiFi network and I am using the tutorial here for the android server. When it receives a connection, I log the message like this:

String read;
Log.i("COB", "test log");
while((read = input.readLine()) != null) {
     Log.i("COB", read);
}

In the logcat in android studio, it prints me the date and time but not the message it seems:

06-25 09:55:12.213    9573-9648/cob.vivid.app I/COB﹕ test log
06-25 09:55:12.213    9573-9648/cob.vivid.app I/COB﹕ [ 06-25 09:55:12.424  1025: 1079 D/WifiStateMachine ]

I am using ncat for windows and I type the following in:

echo messageTest & echo. | ncat {IP ADDRESS} {PORT}

Obviously I use the actual ip and port.

I know that the connection worked because as soon as I enter the ncat command it prints out the logs, but I don't understand why it isn't printing the message as well. Also, what is the 1025: 1079?

I have fixed it by removing the EOL character & echo..

If someone could explain this solution, then that would be great!

You must send EOL character. Without it, the line is not completed and readLine will not return it.

Also, you take a look at NanoHTTPD which is HTTP server implementation that works smooth on Android and so you have not to do all the work from the scratch.
