Filip Maj updated CB-2787:
--------------------------
Description:
I had tried to download more than 300 files and then it hit error after that.
Seems like some IO Connection was not properly closed. I wrote a small code to
test it out.
Any idea? How to file a report or get a source of phonegap to check the real
cause?
{code}
var counter = 500;
function DownloadFile() {
if (counter == 0) {
DownloadComplete();
return;
}
var ft = new FileTransfer();
var downloadUrl = "<source>";
var dlPath = "<target>"
ft.download(downloadUrl, dlPath, function(entry) {
counter--;
UpdateProgress();
DownloadFile();
}, function(error) {
DownloadFailed();
}, true);
}
{code}
note: <target> and <source> is alright because it was it failed when the
counter goes until 300+.
