telnet ソケット入力から「アーティスト - タイトル」を解析したいと考えています。現在、最後の行「END」のみを表示しています。私は何を間違っていますか？java.plsヘルプの初心者です...

仕事に私の活動スクリプト：

try {
        Socket s = new Socket("10.0.2.2", 5555);


        BufferedReader in = new BufferedReader(new InputStreamReader(s.getInputStream()));
        BufferedWriter out = new BufferedWriter(new OutputStreamWriter(s.getOutputStream(), "ISO8859_1"));



        String on_air = "request.on_air" + System.getProperty("line.separator");
        out.write(on_air);
        out.flush();
        Log.i("TcpClient", "sent: " + on_air);
        String on_airin = in.readLine() + System.getProperty("line.separator");
        Log.i("TcpClient", "received: " + on_airin);
        String metadata = "ao.metadata "+ on_airin + System.getProperty("line.separator"); 
        out.write(metadata);
        out.flush();
        Log.i("TcpClient", "sent2: " + metadata);
        String metadatain = in.readLine() + System.getProperty("line.separator");
        Log.i("TcpClient", "received: " + metadatain);

        String line = in.readLine();
        while (line != null) {

            line = in.readLine();


            System.out.println(line);
            output = (TextView) findViewById(R.id.textView2);
            output.setText(line);





//tv.setText(online + formatedDate );
        output = (TextView) findViewById(R.id.textView1);



s.close();

    }} catch (UnknownHostException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    }

}

readLine()印刷前に追加の作業を行います。次の 3 行を折りたたみます。 

String line = in.readLine();
while (line != null) {
    line = in.readLine();

の中へ

String line = null;
while ((line = in.readLine()) != null) {

また、ループSocket内を閉じているように見えるため、問題が発生する可能性があります。while
