求助：app Socket作为服务端使用程序假死while的锅，如何解决，以下代码可以跑通，就是页面假死

if (plus.os.name == "Android") {
ServerSocket = plus.android.importClass("java.net.ServerSocket");
PrintWriter = plus.android.importClass("java.io.PrintWriter");
BufferedWriter = plus.android.importClass("java.io.BufferedWriter");
OutputStreamWriter = plus.android.importClass("java.io.OutputStreamWriter");
BufferedReader = plus.android.importClass("java.io.BufferedReader");
InputStreamReader = plus.android.importClass("java.io.InputStreamReader");
//var socket = new Socket("127.0.0.1", 8081);
//测试改良
var StrictMode = plus.android.importClass("android.os.StrictMode");
var Build = plus.android.importClass("android.os.Build");
if (Build.VERSION.SDK_INT > 9) {
var policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
StrictMode.setThreadPolicy(policy);
}
var serverSocket = new ServerSocket(12345);

                socket = plus.android.importClass("java.net.Socket");  
                socket = serverSocket.accept();  

                //获取输出流  
                var outputStreamWriter = new OutputStreamWriter(socket.getOutputStream());  
                var bufferWriter = new BufferedWriter(outputStreamWriter);  
                out = new PrintWriter(bufferWriter, true);  
                out.println("88888Conneted...");  

                //获取输入流  
                var inputStreamReader = new InputStreamReader(socket.getInputStream());  
                var br = new BufferedReader(inputStreamReader);  
                //console.log(msg);  
                var responseLine = "";  

                while ((responseLine = br.readLine()) != null) { //用readLine接收数据是，会自动抛弃换行符，如果为了保持数据的格式，需要在这里加上一个换行标识符  

                    //returnStr += responseLine + "\n";  
                    console.log(responseLine);  
                }
