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.
