How can I download files from an https URI in android phonegap application?

Question

how to download files with https protocol in android ? I'm try to use it, but keep getting an error.

My download code:

var fileTransfer = new FileTransfer();
          fileTransfer.download(
                task_url,
                fileListDir + fileName,
            function(entry) {
                mylog("download complete: " + entry.fullPath);
            },
            function(error) {
                mylog("download error source " + error.source);
                mylog("download error target " + error.target);
                mylog("upload error code" + error.code);
            });
