Phonegap Image Upload works only once

Question

my app needs to upload photos to a server. This works great when uploading the first captured photo. When I capture another photo, the upload fails.

Here is my code:

    // Upload files to server
function uploadFile(mediaFile) {

    $.mobile.loading( 'show' );
    var path = mediaFile;
    alert(path);

    var options = new FileUploadOptions();
    options.mimeType="image/jpeg";

    var params = new Object();
    params.fullpath = path;
    params.eventID = eventID;


    options.params = params;
    options.chunkedMode = true;

    var ft = new FileTransfer();
    ft.upload( path, "http://dev.tellthedj.de/db/uploadPhoto.php",
        function(result) {
            $.mobile.loading( 'hide' );
            alert("Foto erfolgreich hochgeladen");   

            // Geschossenes Foto aus Cache löschen
            var file = new FileEntry(); 
            file.fullPath = mediaFile;

            file.remove(success, fail);

            function success(){
                alert("success");
            }

            function fail(){
                alert("cache löschen nicht erfolgreich")
            }

        },
        function(error) {
            $.mobile.loading( 'hide' );
            alert("Upload nicht erfolgreich. Bitte checke deine Internet-Verbindung: ");
            console.log(error.message);
        },
        options
        );
}

mediaFile is the location of the captured photo in cache folder. The second photo I want to upload always calls "Upload nicht erfolgreich..." and i got this error in LogCat

The strange thing is, that the first upload works fine, the second fails with error code 3. The third works, the fourth -> error...

Answer 1

Okay, I just spent the last day or so working through the same issue. What worked for me was to set the header to close the connection.

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

Found this answer on the cordova Bug Tracker site: https://issues.apache.org/jira/browse/CB-2293?focusedCommentId=13696238&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-13696238

Hope that helps, I know how frustrated I was with this one too!
