I have an Android app that communicates over a TCP socket with a server I wrote. The method I'm using now to read and write output works fine for smaller strings (up to 60kB) but I get an exception thrown when the string is much longer than that. Here is the relevant part of what I have for the server and client:

Server:

            DataInputStream dis = null;
            DataOutputStream dos = null;

            try {
                    dis = new DataInputStream(server.getInputStream());
                    dos = new DataOutputStream(server.getOutputStream());

                    String input = "";
                    input = dis.readUTF();
                    handle_input info = new handle_input(input, id);
                    String xml = info.handle();

                    dos.writeUTF(xml);

                    server.close();

            } 

Client:

        Socket socket = null; 
        DataOutputStream dos = null;
        DataInputStream dis = null;
        Boolean result;

        try {
            socket = new Socket(ip, port);
            dos = new DataOutputStream(socket.getOutputStream());
            dis = new DataInputStream(socket.getInputStream());
            dos.writeUTF(the_text);
            String in = "";
            while (in.equals("")) {
                in += dis.readUTF();
            }
        }

How can I modify it to deal with potentially enormous Strings? I've been looking around and can't seem to find a clear answer.

Thanks.
