Hi,

I've been working with the File API that is available from Cordova for working with photos and then uploading those images.  I'm running into issues with the FileEntry class and also the FileTransfer class.  Here are some code snippets, I've remarked out the FileTransfer call in this example:

var img = new Image();
img.style.display = 'block';
img.src = "http://localfile/Simulator////C:/Users/me/Pictures/bus.png";

var App = {
        CachedPictures[{ID: 0, ImageBinary: img, ImageNm: "xx", ImageNotes: "xxxx"}],
        SavePicture: function () {
            for (var i = 0; i < App.CachedPictures.length; i++) {
               
                var lastImage = App.CachedPictures[App.CachedPictures.length - 1];
                var url = 'SomeURL?ImageNm=' + encodeURIComponent(lastImage.ImageNm) +
                            '&ImageNotes=' + encodeURIComponent(lastImage.ImageNotes);

                // get instance of file object
                var filePath = lastImage.ImageBinary.src.substr(lastImage.ImageBinary.src.lastIndexOf('///') + 3);
                console.log("filePath:\t" + filePath);
                var file = null;
                window.requestFileSystem(LocalFileSystem.PERSISTENT, 0,
                    function (fileSystem) {
                        fileSystem.root.getFile(filePath, { create: true, exclusive: false },
                            function (parent) {
                                console.log(parent);
                            },
                            function () {
                                console.log("** error getting file");
                            });
                    },
                    function (evt) {
                        console.log('** failed in file system request')
                        console.log(evt);
                    });

/*                var imageURI = lastImage.ImageBinary.src;
                var options = new FileUploadOptions();
                options.fileKey = "file";
                options.fileName = imageURI.substr(imageURI.lastIndexOf('/') + 1);
                console.log(options.fileName);
                options.mimeType = "text/plain";

                console.log('*** original image source');
                console.log(lastImage.ImageBinary.src);
                console.log('*** modified path');
                console.log(options.fileName);
               

                var ft = new FileTransfer();
                ft.upload(imageURI, url,
                    function (r) {
                        console.log("Code = " + r.responseCode);
                        console.log("Response = " + r.response);
                        console.log("Sent = " + r.bytesSent);
                    },
                    function (error) {
                        // error.code == FileTransferError.ABORT_ERR
                        alert("An error has occurred: Code = " + error.code);
                        console.log("upload error source " + error.source);
                        console.log("upload error target " + error.target);
                    },
                    options);
                ft.abort();*/
            }
        }
}

When trying to use the file FileEntry class i get the following in my console.log call:

filePath: C:/Users/me/Pictures/bus.png App.js:152

** failed in file system request App.js:165

FileError {code: "Not Supported in Simulator"}


Is there a plan in the future to support the Cordova File APIs from the simulator?

Hello Joe,

As you have found the hard way, Cordova File API is not supported in the Icenium Simulator. We do plan to add support for all core Cordova APIs (now plugins) into the Simulator. File API would be one of the first, with support comming as early as end of January 2014.

Hi Amir,

As noted in our previous post, the Cordova File API would be added to the Icenium Simulator in the next major version of the product.

Hi,

The support for the Cordova File API is added in the simulator functionality for all of the AppBuilder clients except the In-Browser client. You can check this here. To try it out, you can check our File Sample, which successfully writes, reads and deletes files from your computer. Note, you might need to adjust the Root Folders Location accordingly to your scenario and account permissions.

Further, the simulator (except the one in the In-Browser client) also supports the Cordova FileTransfer API. You will find the sample project for it, here.

I hope this helps. Please, let me know if there is anything more particular that prevents you for using the above APIs and I will be glad to assist you further.

Regards,
