Cordova FileTransfer plugin not working on Android 5+

I'm building an app with PhoneGap Build, only targeting Android. One of the features is to download a file from a web server to the device.
This code works perfectly on Android 4.x, but doesn't work on Android 5.x and above:
var URL = 'https://example.com/path/to/file.pdf?auth_token=123xxxx';
var Folder_Name = 'Download';
var File_Name = URL.split('/');
File_Name = File_Name[File_Name.length - 1].split('?');
File_Name = File_Name[0];
window.requestFileSystem(LocalFileSystem.PERSISTENT, 0, fileSystemSuccess, fileSystemFail);
function fileSystemSuccess(fileSystem) {
var download_link = encodeURI(URL);
var directoryEntry = fileSystem.root; // to get root path of directory
directoryEntry.getDirectory(Folder_Name, {
create: true,
exclusive: false
}, onDirectorySuccess, onDirectoryFail); // creating folder in sdcard
var rootdir = fileSystem.root;
var fp = rootdir.toURL(); // Returns Fullpath of local directory
fp = fp + "/" + Folder_Name + "/" + File_Name; // fullpath and name of the file which we want to give
console.log("Path to local file: " + fp);
// download function call
filetransfer(download_link, fp);
}
function onDirectorySuccess(parent) {
console.log('directory created successfully');
// Directory created successfuly
}
function onDirectoryFail(error) {
//Error while creating directory
console.log("Unable to create new directory: " + error.code);
}
function fileSystemFail(evt) {
//Unable to access file system
console.log(evt.target.error.code);
}
function filetransfer(download_link, fp) {
var fileTransfer = new FileTransfer();
// File download function with URL and local path
fileTransfer.download(download_link, fp,
function(entry) {
alert('The file was successfully downloaded, you can access it in /' + Folder_Name + '/' + File_Name + '.');
console.log("download complete: " + entry.fullPath);
},
function(error) {
//Download abort errors or download failed errors
console.log("download error source " + error.source);
console.log("download error target " + error.target);
console.log("download error code" + error.code);
}
);
}
Don't get anything in the console, no error and none of the log lines, meaning that none of the callbacks gets triggered.
Did anybody else have this mysterious issue?
Thanks

Using File Transfer Plugin in Phonegap Application

I have more than 2 weeks that i tried to download file PDF in phonegap application using the File Transfer Plugin but it didn't work!! i make everything for that:
-installing the last version of phonegap
-installing the last version of File Transfer plugin
And this is the code to integrate in Javascript interface:
var fileTransfer = new FileTransfer();
fileTransfer.download(
"http://developer.android.com/assets/images/home/ics-android.png",
"file://sdcard/ics-android.png",
function(entry) {
alert("download complete: " + entry.fullPath);
},
function(error) {
alert("download error source " + error.source);
alert("download error target " + error.target);
alert("upload error code" + error.code);
});
But it seems wrong!!! I have like a result last three alerts in an android device:
-Download error source
-Download error target
-Upload error code
What i should doing?!!

Request you to check out my github page that contains a sample Cordova app which downloads PDF file from external URL and downloads it to the device.
This sample app is tested both in iOS and android devices. Hope it helps.

According to file transfer plugin documentation, first of all you need to create a file where you will store your remote data. Your code should look like this:
{
//call this after onDeviceReady event
...
var savePath = cordova.file.externalRootDirectory;
var fileName = "ics-android.png";
var url = encodeURI("http://developer.android.com/assets/images/home/ics-android.png");
downloadFile(savePath, fileName, url);
...
}
function downloadFile(savePath, fileName, remoteURL) {
window.resolveLocalFileSystemURL(savePath, function (dirEntry) {
console.log('file system open: ' + dirEntry.name);
createFile(dirEntry, fileName, function (fileEntry) {
download(remoteURL, fileEntry);
});
}, function (err) { alert(err) });
}
function createFile(dirEntry, fileName, callback) {
// Creates a new file or returns the file if it already exists.
dirEntry.getFile(fileName, { create: true, exclusive: false }, function (fileEntry) {
callback(fileEntry);
}, function (err) { alert(err) });
}
function download(remoteURL, fileEntry) {
var fileURL = fileEntry.toURL();
var fileTransfer = new FileTransfer();
fileTransfer.download(
remoteURL,
fileURL,
function (entry) {
alert("download complete: " + entry.fullPath);
},
function (error) {
alert("download error source " + error.source);
alert("download error target " + error.target);
alert("upload error code" + error.code);
});
}
Note that for path I use cordova.file.externalRootDirectory, so you get root sdcard path for file.

Apache Cordova -- Download file from local web directory to Android/iOS directories?

having a bit of trouble with my download function for Cordova. I have a function here:
document.addEventListener("deviceready", function () {
var fileUrl = e.target.getAttribute('data-soundurl');
console.log(fileUrl);
//returns as "../www/card-sounds/sound2.m4a"
var fileOutputPath = e.target.getAttribute('data-quote') + ".m4a";
console.log(fileOutputPath);
//returns as "Sound Title.m4a"
var fileTransfer = new FileTransfer();
var output = "file:///android_asset/www/res/db/"+fileOutputPath;
fileTransfer.download(
fileUrl,
output,
function(entry) {console.log("download complete: " + entry.toURL());},
function(error) {console.log("download error source " + error.source);
console.log("download error target " + error.target);
console.log("upload error code" + error.code);
},
false,
{headers:{"Authorization": "Basic dGVzdHVzZXJuYW1lOnRlc3RwYXNzd29yZA=="}}
);
console.log(output);
//returns as "file:///android_asset_www_res/db/Sound Title.m4a"
}, true);
And my log output just shows:
download error source null
download error target null
upload error codenull
I can't seem to get any sort of .root part of the FileSystem to actually give me a defined string so I'm just trying to get it to download to Android for now. Am I doing something fundamentally wrong? I am so confused here.

Try this :
var output = "/res/db/"+fileOutputPath;

For your output use
var output = cordova.file.externalRootDirectory + fileOutputPath;
cordova.file.externalRootDirectory should give you something like "file:///storage/emulated/0/"

Download file phonegap sending post data

I have some client-side infos (a long associative array encoded with JSON) that I would like to send to the server with POST, to create an image based on those infos. The goal is to download that image using Phonegap primitives and saving it to the local storage.
Is there a way to do it?
Looking to the phonegap reference is there no way to send explicitely post data. Should I work with the parameter "header" (???) ?
Example:
var fileTransfer = new FileTransfer();
var uri = encodeURI("http://some.server.com/create_my_image.php");
fileTransfer.download(
uri,
filePath,
function(entry) {
console.log("download complete: " + entry.fullPath);
},
function(error) {
console.log("download error source " + error.source);
console.log("download error target " + error.target);
console.log("upload error code" + error.code);
},
false,
{
// HERE ADD SOME CODE TO SEND POST DATA?
headers: {
"???": "???"
}
}
);

Download images and save locally on iPhone Phonegap app

I've already managed to save a web page (x/html) successfully, but I'd also like to save the images and mp4 videos that are contained in it, for further visualization in offline mode.
I've got access to the iOS filesystem, so I save the html by obtaining the code through an AJAX request, and later saving it to a file.
I don't really know how to do the same with video and images. I have a server to which I can send queries from my app, so it shows exclusively the content I need to download, with the optimal headers in case its necessary. I just don't know how to "download" it from the client side (Javascript).
Thanks in advance for any help.

You can use a FileTransfer object to download a remote image to a local file.
This is the latest official sample snippet:
// !! Assumes filePath is a valid path on the device
var fileTransfer = new FileTransfer();
var uri = encodeURI("http://some.server.com/download.php");
fileTransfer.download(
uri,
filePath,
function(entry) {
console.log("download complete: " + entry.fullPath);
},
function(error) {
console.log("download error source " + error.source);
console.log("download error target " + error.target);
console.log("upload error code" + error.code);
},
false,
{
headers: {
"Authorization": "Basic dGVzdHVzZXJuYW1lOnRlc3RwYXNzd29yZA=="
}
}
);

You can only do it natively I'm afraid.
I'm doing it through a FileDownload PhoneGap Plugin that I wrote, using NSURLConnection. I pass in the url to download to the plugin through Javascript, and a target location (and it even gives me download progress).

Have not tested it yet, but the documentation at PhoneGap looks quite promising http://docs.phonegap.com/en/1.0.0/phonegap_file_file.md.html

I have used this snippet on my ios app project:
window.requestFileSystem = window.requestFileSystem || window.webkitRequestFileSystem;
window.requestFileSystem(LocalFileSystem.PERSISTENT, 0, success, fail);
var target_directory="";
function fail() {
//alert("failed to get filesystem");
}
function downloadImage(url, filename){
alert("download just started.");
try{
var ft = new FileTransfer();
ft.download(
url,
target_directory + filename,
function(entry) {
//alert("download complete!:" + entry.nativeURL ); //path of the downloaded file
},
function(error) {
//alert("download error" + error.code);
//alert("download error" + JSON.stringify(error));
}
);
}
catch (e){
//alert(JSON.stringify(e));
}
}
function success(fileSystem) {
target_directory = fileSystem.root.nativeURL; //root path
downloadImage(encodeURI("http://upload.wikimedia.org/wikipedia/commons/2/22/Turkish_Van_Cat.jpg"), "cat.jpg"); // I just used a sample url and filename
}
