关于android上传视频的问题,在线等急。。。

[dh1314al]

情况是这样的,我用android上传一段视频到服务器上,服务器可以成功接收到该视频文件,但是文件大小变小了,也不能正常播放！

public class UploadActivity extends Activity

{

        Button btnPost=null;

        Button btnPost1=null;

    @Override

    public void onCreate(Bundle savedInstanceState) 

    {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.main);

        btnPost=(Button) findViewById(R.id.btnPost);

        btnPost1=(Button) findViewById(R.id.btnPost1);

        btnPost1.setOnClickListener(new OnClickListener()

        {

                        @Override

                        public void onClick(View v) 

                        {

                                String actionUrl="http://192.168.1.100:8080/web/upload.do";

                int c=0;

              }

            outStream.close();

            conn.disconnect();

            } catch (Exception e) {

            e.printStackTrace();

            } finally {

            if(null != conn){

            conn.disconnect();

            conn = null;

            }

            if(null!=outStream){

            try {

            outStream.close();

            } catch (IOException e) {

            //  

            }

            outStream = null;

            }

            }

    }

这是android端的代码,

//获取输入流，是HTTP协议中的实体内容

               ServletInputStream  sis=request.getInputStream();

               //缓冲区

               byte buffer[]=new byte[2048];

//               File file=new File("d:\\123.mp4");

               File file=new File("d:\\11.jpg");

               FileOutputStream fos=new FileOutputStream(file);

               int len=0;

               //把流里的信息循环读入到文件中

               while((len=sis.read(buffer, 0, 2048))!=-1)

               {

                   fos.write(buffer, 0, len);

                   len=sis.readLine(buffer, 0, 2048);

               }

               fos.close();

               sis.close();

这是我servlet服务端代码,各位大哥帮忙解决一下吧！

[bean]

客服端是 byte[] buf = new byte[1024];
服务器端是 byte buffer[]=new byte[2048];
是不是这里的原因呢 改为一样试试

谢谢 你的回答！不是这个原因,希望高手给解决一下吧！！
