如何成功退出程序

Question

今天写了一个程序，运行成功，快完成了。但是我发现当我关闭Socket,BufferedReader和PrintWriter时，程序总是显示ANR。我对此感到困惑。有没有有什么顺序可以关闭程序吗？？

@Override
        public void onClick(DialogInterface dialog, int which) {
            // TODO Auto-generated method stub
            try {
                mPrintWriter.println("192.168.2.131;"+mSocket.getLocalAddress().toString().replace("/", "")+";byebye");
                mPrintWriter.close();
                mBufferedReader.close();
                mSocket.close();
                net_.interrupt(); //This is the thread to send and receive data.
            } catch (IOException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }

        }

这是我的问题，我想消除这个错误以保持我的程序完美。谢谢

也许可以尝试类似的方法

    @Override
    public void onClick(DialogInterface dialog, int which) {

      thread = new Thread(new Runnable() {
        @Override
        public void run() {
            try {
                mPrintWriter.println("192.168.2.131;"+mSocket.getLocalAddress().toString().replace("/", "")+";byebye");
            } catch (IOException e) {
                e.printStackTrace();
            } finally{
                mPrintWriter.close();
                mBufferedReader.close();
            }

            try{
                net_.interrupt();
            }catch (IOException e) {
                 e.printStackTrace();
            }finally{
                mSocket.close();
            }
        }
     });

     thread .start();
    }

在您的应用程序结束时，您应该加入该线程

   thread.join();
