涉及android上传 io异常，是因为线程的问题

写在线程里，因为要访问网络
 Thread trd=new Thread(new Runnable() {
                    @Override
                    public void run() {
                        try
                        {
                            访问网络部分
                        }
                        catch (IOException ioe)
                        {

                        }
                    }
                });
                trd.start();
