I can download files with phonegap api. (I use cordova 2.9.1) But only if I know the url, for example: http://domain.com/url/to/img/moo.png.

But in my server I want to read the binary data of the file and send the binary string to the phonegap app.

Is this possible to achieve this???

Here is the code: var fileTransfer = new FileTransfer(); // var uri = encodeURI("http://zielekols.com/Bilder/logo.png");

var uri = encodeURI('url/to/get');

fileTransfer.download(
    uri,
    '/storage/emulated/0/moo.pdf',
    function(entry) {
        console.log("download complete: " + 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);
    },
    false
);

you mean you are getting png image in string format and want to convert in file right? – Biraj Zalavadia Apr 04 '14 at 10:12
Yes. Lets say I want an image with id 5. The server reads that image as binary and sends my this data. – OOPDeveloper89 Apr 04 '14 at 10:15
I think its is base64 format image string you may getting.Can you confirm this is this base64 encoding you getting? – Biraj Zalavadia Apr 04 '14 at 10:17
Yes, I get base64 String. – OOPDeveloper89 Apr 04 '14 at 10:25
Actually it is binary string but its no problem to convert to base64. – OOPDeveloper89 Apr 04 '14 at 10:26
yes you need to decode the string and you will get byte array store to file thats it – Biraj Zalavadia Apr 04 '14 at 10:27
You mean I have to send base64 String to my app? – OOPDeveloper89 Apr 04 '14 at 10:29
Are you getting this kind of string? VBORw0KGgoAAAANSUhEUgAAAAUAAAAFCAYAAACNbyblAAAAHElEQVQI12P4//8/w38GIAXDIBKE0DHxgljNBAAO9TXL0Y4OHwAAAABJRU5ErkJggg== – Biraj Zalavadia Apr 04 '14 at 10:29

Yes I read that yesterday. I hoped there is an integrated solution in phonegap but seems this is not the case. Then I have to implement this plugin :-) Thank you – OOPDeveloper89 Apr 04 '14 at 11:16
