Question

Hii i am uploading a file to server using socket and i need the percent of file loaded?how can i do that?i have the maximun value i.e the file length ,how can i get how much file has been uploaded?

FileInputStream fis = new FileInputStream(fil);
                BufferedInputStream in = new BufferedInputStream(fis);
                BufferedOutputStream out = new BufferedOutputStream(skt.getOutputStream());

                //Write the file to the server socket           
                int i;

                while ((i = in.read()) != -1) {
                    publishProgress(???);
                    out.write(i);                   
                    System.out.println(i);
                }

I need to pass the length of file uploded in the publishProgress method.

Answer 1

using buffered copying

FileInputStream fis = new FileInputStream(fil);
BufferedInputStream in = new BufferedInputStream(fis);
BufferedOutputStream out = new BufferedOutputStream(skt.getOutputStream());

//Write the file to the server socket
int i;
int written = 0;
byte[] buf = new byte[512];

while ((i = in.read(buff)) != -1) {  

    out.write(buff,0,i);
    written += i;
    publishProgress((double)written/length);
    //passing a double value from 0-1 to say how much is transmitted (length is length of file)
    System.out.println(buff+", "+i);
}
