I am facing while uploading a video after i record it on my android phone. video is not uploading and its object is not found . i am using android SDK 2.2 and Titanium SDK 1.6.2.

Here is my Code for recording and uploading: ```````````````````````````````

var videoUri = null;

var b ; recordButton.addEventListener('click', function() {

var intent = Titanium.Android.createIntent({ action: 'android.media.action.VIDEO_CAPTURE' });
Titanium.Android.currentActivity.startActivityForResult(intent, function(e) {
    if (e.error) {
        Ti.UI.createNotification({
            duration: Ti.UI.NOTIFICATION_DURATION_LONG,
            message: 'Error: ' + e.error
        }).show();
    } else {
        if (e.resultCode === Titanium.Android.RESULT_OK) {
            videoUri = e.intent.data;


           btnCancelNormal.visible = true;
           lblsignUp.visible = true;
           btnContinueHover.visible = true;
       } else {
            Ti.UI.createNotification({
                duration: Ti.UI.NOTIFICATION_DURATION_LONG,
                message: 'Canceled/Error? Result code: ' + e.resultCode
            }).show();
        }
    }
});

});

                if(eee.index == 0)
                {
                     var source = Ti.Filesystem.getFile(videoUri); 
                                 b = source.read();
                    var portfolioWindow = Titanium.UI.createWindow({
                        url:'progress.js',
                        id:win.id,
                        titleWork:txtTitle.value,                                   imageObject:b

                    }); 
                    portfolioWindow.open({fullscreen: true });                      
                    //Titanium.UI.currentTab.open(portfolioWindow,{animated:true});                         
               }
