本文详细介绍了如何通过HTTP协议发送GET请求，并从远程服务器下载图片的过程，包括创建URL、设置连接超时、发送请求、接收响应、解析数据等关键步骤。

/*URL url = new URL("http://192.168.1.127:81/tmpfs/auto.jpg?1433329819419");  
                    HttpURLConnection conn= (HttpURLConnection) url.openConnection();  
                    conn.setRequestMethod("GET");  
                    conn.setConnectTimeout(5*1000);  
                    conn.connect();  
                    InputStream in=conn.getInputStream();  
                    ByteArrayOutputStream bos=new ByteArrayOutputStream();  
                    byte[] buffer=new byte[1024 * 17];  
                    int len = 0;  
                    while((len=in.read(buffer))!=-1){  
                        bos.write(buffer,0,len);  
                    }  
                    byte[] dataImage=bos.toByteArray();  
                    bos.close();  
                    in.close();  */


                    /*org.apache.http.client.HttpClient client2 = new DefaultHttpClient();
