    How to get remaining time in downloading


    I am developing a application in which songs are download from the server.
    I am able to download it but the problem is that I am not able to get the remaining time while the song is 2 min remaining ....
    How can I do this ???

    You need to know the full size of the file. If you know that, then you take a measurement of how far you have got so far, and the time it's taken so far. Divide the time taken so far by the proportion done (always less than one, so you should get a bigger value), and display that as "time remaining".

    So, if we have a 4MB file, we've got 1.2MB so far in 10 seconds:
    totalSize = 4 * 1024 * 1024;
    doneSize = (int)(1.2 * 1024 * 1024); 
    timeUsed = 10;
    timeRemaining = timeUsed * ((double)doneSize / totalSize);
    Compilers can produce warnings - make the compiler programmers happy: Use them!
    Please don't PM me for help - and no, I don't do help over instant messengers.
