Code Sample for FileTransfer

Is there any code sample available on using FileTransfer.Download API. I keep getting "Uncaught ReferenceError: FileTransfer is not defined" in the simulator console window.

Here is the code:

function transferFile(fileSystemPath){
    var transfer = new FileTransfer(),
    uri = encodeURI("http://icenium.com/assets/img/icenium-logo.png");
    filePath = fileSystemPath+'/sample.png';
    transfer.download(
        uri,
        filePath,
        function(entry) {
            var image = document.getElementById("result");
            image.src=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);
        }
    );
}

Got response on Github. Essentially response is, yes there's sample code on FileTransfer, but they don't work in Simulator.

 hi,
i am working on fileupload  to server using phonegap.when i am running in appbuilder simulator "error code=3" error is showing. i searched in google but i am not found any solution.what it means? and how to resolve?

Hi divya,

Error 3 is connection error, you can see the errors in the respective Cordova file for the core plugin you're using. We've added support for Cordova FileTransfer plugin in the AppBuilder simulator in the latest version released early this week, so make sure you're up to date.

Also does your app function correctly if deployed on an actual app (not simulator)?

this is my code,  can any body tell me where is the error(error code :3)

 (function (global) {
    var submitViewModel,
        app = global.app = global.app || {};

    submitViewModel = kendo.data.ObservableObject.extend({
       

        onsubmit: function () {
            // Wait for device API libraries to load
        //
        document.addEventListener("deviceready", onDeviceReady, false);

        // device APIs are available
        //
        function onDeviceReady() {
            // Retrieve image file location from specified source
            navigator.camera.getPicture(
                uploadPhoto,
                function(message) { alert('get picture failed'); },
                {
                    quality         : 50,
                    destinationType : navigator.camera.DestinationType.FILE_URI
                }
            );
        }
           

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

                
                    var params = new Object();
                    params.ProfileId = "12345";
                    params.ProductLeadType = "1";
                    params.ProductLeadName = "test";
                    params.ProductLeadDesc = "test desc";
                  //  options.params = params;
                     
           
                // Transfer picture to server
            var ft = new FileTransfer();
            
            ft.upload(imageURI, "http://115.119.249.70/tobocwebservices.asmx/SaveImage", win, fail, options,true);
        }
              
        function win(r) {
            console.log("Code = " + r.responseCode);
            console.log("Response = " + r.response);
            console.log("Sent = " + r.bytesSent);
        }

        function fail(error) {
            
            alert("An error has occurred: Code = " + error.code);
         //   console.log("upload error source " + error.source);
         //   console.log("upload error target " + error.target);
        }

        
      }      
    });

    app.submitService = {
        viewModel: new submitViewModel()
    };
})(window);

I tested in device  but it showing same error

Hello divya,

There is nothing visibly wrong with the code, you can use remote debugging tools like jsHybugger and Weinre to try to pinpoint what is going wrong. You can also setup Fiddler to intercept your device's traffic which would give you a clue what's going on if the problem is failing/wrong requests/responses.

Divya,

Try these settings:

            destinationType: navigator.camera.FILE_URI,
            encodingType : navigator.camera.EncodingType.JPEG, 
            quality: 40,
            targetWidth: 500,
            targetHeight: 500,
            saveToPhotoAlbum: 1

and something like this:

        uploadPhoto: function (imageURI) {
            var options = new FileUploadOptions();
           
            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("http://your-path"), win, fail, options, true);
        } 

we spent a week on this same problem, and it all came down to that extra "true" parameter on the upload, setting the file dimensions and making sure savetophotoalbum was set.

error code 1 and 3 were never server errors. they were always just fileupload failing and not giving a proper reason why.

I debugged above code,error is rising in cordova.js file and line is

ICE_CordovaExecutionProcessor.Execute(service, action, callbackId, JSON.stringify(args)); here
service:filetransfer
action:upload
callbackId:FileTransfer931564722
how to resolve this?

Michael your settings changes were the answer for me, I've spent most of the day trying to figure out code 1 and 3 errors. All working now. Thanks
