Phonegap File Transfer of picture fails on every other picture: Error code 3 with FileTransfer upload

Question

I answered this question myself since it took me a long time to find the solution for it and it wasn't documented very well.

Answer 1

While trying to use FileTransfer() to upload images from a phonegap app on android to a remote server i kept getting an error code 3 on every alternate file upload.

It worked once but instantly when i tried again it would throw an error without even sending the file to the server.

The code i am using for the file upload was :

The key to making it work was to add a header option.

options.headers = {
        Connection: "close"
    }
    options.chunkedMode = false;

The complete code :

var options = new FileUploadOptions();

                        options.fileKey="file";
                        options.fileName=imageURI.substr(imageURI.lastIndexOf('/')+1);
                        options.mimeType="image/jpeg";
                        options.chunkedMode = false;
                        *options.headers = {
                           Connection: "close"
                        };*

                        // setup parameters
                        var params = {};
                        params.fullpath =imageURI;
                        params.name = options.fileName;



                        var ft = new FileTransfer();

                        ft.upload(imageURI, encodeURI(url+'/account/profile-pics'), win, fail, options);


 function win(r) {
                  //file uploaded successfully
                }
            function fail(error) {


                alert("An error has occurred: Code = " + error.code);
                alert("upload error source " + error.source);
                alert("upload error target " + error.target);
            }
