{code}
I use cordova 2.7 (same effect with cordova 2.2)
My app worked fine on Android 2.3, 3.x
With Android 4.0 I got this issue, but using a timeout of 1 millisecond solved my problem.
This workaround also worked for Android 4.1.x.
But now with Android 4.2.2 (Nexus 7) I can't get rid of this problem, even with bigget timeouts
My code looks like this:
{code:javascript}
var urls=['http://foo', ..., 'http://bar'];
var loader = new FileTransfer();
function loader(){
var url = window.urls.pop();
if(url === undefined) return;
window.loader.download(
url,
window.getAbsoluteFileNameForUrl(url),
function(e){setTimeout(loader,100)},
function(e){setTimeout(loader,100)}
);
}
{code}

> PhoneGap FileTransfer.Download more than 300 files
> --------------------------------------------------

> Key: CB-2787
> URL: https://issues.apache.org/jira/browse/CB-2787
> Project: Apache Cordova
> Issue Type: Bug
> Components: Android
> Affects Versions: 2.5.0
> Reporter: Cho
> Assignee: Ian Clelland
>
> 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+.
