[jira] [Commented] (CB-2787) PhoneGap FileTransfer.Download more
than 300 files
[ https://issues.apache.org/jira/browse/CB-2787?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13819192#comment-13819192 ]
Cho commented on CB-2787:
-------------------------
Hi,
var ft = new FileTransfer();
ft.download(sorceURI, targetURI, function(entry)
{
//call your own function.
// the magic line
entry = null; }
);
Not sure how much I can help but basically it is at javascript level that I am setting it to null. Not sure how doesn't all this related way back to JAVA though.
The problem is re-occur after the new plugin adopt mentioned by Gregor Gabriel? For mine, I didn't adopt the new plugin provided.
I can't guarantee but most likely I am downloading from https as well and didn't hit any problem.

> Project: Apache Cordova
> Issue Type: Bug
> Components: Android, Plugin File Transfer
> 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+.
