Question

I have a link to download mp3 on all mobile device they can read them.
I also have an Acer E320 with Android 2.3.4 and I want to download my mp3 by clicking my link (web server Apache; this is some PHP source behind that link).

I tried with a BlackBerry, and I got the file.
I tried with my Firefox browser with a user-agent of a Samsung Galaxy S with Android, and I got the file.
I tried with my Acer E320 with the same Android 2.3.4, and… I didn’t get the file.

I am obviously sure that comes from the OS, I’ll try with a Windows Phone tomorrow but I’m pretty sure this will works.

Here are my sources for the download:

    <?php
    // assume that all variables are correctly set
    header("Pragma: public");
    header("Expires: 0");
    header("Cache-Control:");
    header("Cache-Control: public");
    header("Content-Description: File Transfer");
    header("Content-Type: audio/mpeg");
    header('Content-Disposition: attachment; filename="'.$filename.'";');
    header("Content-Transfer-Encoding: binary");
    header('Content-Range: ' . $download_range);
    header('Content-Length: ' . $download_size);
    readfile($filename);
    ?>

Thank you if you have any idea why this code doesn’t work on an Android phone.

EDIT: I tried with an HTC with Windows Phone OS. The download didn’t start but I can see my hit on the apache log… It seemes that Android is not alone…

2nd EDIT: I finnaly find it: there’s a pre-fetch done with Android that kill my download because of a one-use token.
Thanks all
