Answer 1

I would use a http request to your php server here is a full working example: http://androidexample.com/Upload_File_To_Server_-_Android_Example/index.php?view=article_discription&aid=83&aaid=106

To have the client download I would make a /download.php file and use a get parameter to set the database pk to the url they wanna download. next I would read the file and then use the header to change the PHP's output to file so it causes the client to download via http.

CODE EXAMPLE:

$attachment_location = "filePath";
if (file_exists($attachment_location)) {
    header($_SERVER["SERVER_PROTOCOL"] . " 200 OK");
    header("Cache-Control: public"); // needed for internet explorer
    header("Content-Type: application/zip");
    header("Content-Transfer-Encoding: Binary");
    header("Content-Length:".filesize($attachment_location));
    header("Content-Disposition: attachment; filename=filePath");
    readfile($attachment_location);
die();
} else {
    die("Error: File not found.");
}
