Socket does not receive any data

I have a C# Server and this Java client in Android Studio:

@Override
    public void run() {

        try {
            Socket socket = new Socket("192.168.0.107", 7778);
            BufferedReader inFromServer = new BufferedReader(new InputStreamReader(socket.getInputStream()));

            while (true) {
                currentMessage = inFromServer.readLine();
                System.out.println(currentMessage);

                Thread.sleep(200);
            }
        }
        catch(Exception e) {
            System.out.print("Error: " + e.toString() + "\n");
        }
    }

I have tested the Server with Telnet and the messages a going out as they should, so im almost certain, that the problem somewhere in the client code. I have also tried using a DataInputStream instead of a BufferedReader, but it gives me the same results. Also I don't get any Exeptions.

I have these Permissions in my AndroidManifest.xml:

<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.INTERNET" />

readLine() blocks until there is a full line (terminated by either \r\n or \n) received in the underlying buffer (or the end of the steam has been reached). So unless your server is terminating the data with a linebreak, your program will not print anything. Other than an Exception when the socket times out of course.
