I am trying to download and save a video using URLSession and then play it in video player. But somehow it's not playing, rather it's crashing the app. Here's the code for it.I have tried almost everything to read the exact path of file using nativePath , getNativePath(), file.resolve(), but nothing seems to work. Take a look at the code and suggest a solution. This is for iOS. (iOS Version 8.4)
UPDATED CODE :
var args = arguments[0] || {};
var vidWin = $.winTestVideo;
var isDownloading = false;
var urlSession = require("com.appcelerator.urlSession");
var downloadSession;
var urlArray = ["http://www.kaltura.com/p/{PARTNERID}/sp/{SUBPARTNERID}/playManifest/entryId/{entryId}/format/applhttp/protocol/http/flavorId/{flavorId}/video.mp4",
"http://www.kaltura.com/p/{PARTNERID}/sp/{SUBPARTNERID}/playManifest/entryId/{entryId}/format/applhttp/protocol/http/flavorId/{flavorId}/video.mp4"];
var urlArrIndex = 0;
var progress;
var videoPlayer;
var imageUrl = 'http://dreamatico.com/data_images/rose/rose-4.jpg';

vidWin.add(triggerBtn);
triggerBtn.addEventListener('click', downloadVideoBackround2);

//vidWin.add(img);

// Create a session
session = urlSession.createURLSession(sessionConfig);
// Create a background download task to get the asset with the URL
urlSession.backgroundDownloadTaskWithURL(session,urlArray[0].replace('applhttp','url'));
progress.show();
}
// Monitor this event to receive updates on the progress of the download
Ti.App.iOS.addEventListener("downloadprogress", function(e) {
// Update the progress indicator
Ti.API.error("DOWNLOAD PROGRESS : " + e.totalBytesWritten + "/" + e.totalBytesExpectedToWrite);
progress.value = (e.totalBytesWritten / e.totalBytesExpectedToWrite);
});

The app is crashing when i assign the file to videoPlayer's media property. But when i download the file using HttpClient, it works fine. Not really sure why it's happening as i can't see any error in the logs.
Here are the logs. I have used the [Error] for highlighting the important logging.

My quick guess would be that you have a race condition. Inside of your setTimeout you never actually check to see if the file has been written, like you do when you have finished downloading, assuming at this point that 3s is long enough.
// Notify the user the download is complete if the application is in the background
setTimeout(function() {
//videoPlayer.media = file;
createVideoPlayer();
videoPlayer.media = file;
urlSession.finishTasksAndInvalidate(session);
//videoPlayer.play();
}, 3000);
Additionally, the xcode logs for the device or simulator should be telling you where/what crashed (these may not always appear in the titanium logs)
