    Hello Arun,

    Navigator.camera.getPicture cannot return both DATA_URL and FILE_URI (see Cordova Camera API). If you need to save the picture and have a way to display it as well, use Data URI css technique e.g.:

    url('data:image/png;base64,BASE64_DATA') /* From where you stored you base64 data */

    Make sure to change the content type depending on the MIME type of the image you’re embedding. Additionally make sure to keep the data URI all on one line without line-breaks.

    Steve,

    The problem is you don't get the file name or mime type back on this call.   If you the allow the user to pick any media file, then you don't know if they chose JPEG, MPEG, etc.

    Arun,

    You can't do what you want in one camera call.  As far as I can tell, you have to use FILE_URI first to get the file name and type.  In that callback, then use readAsDataURL with a file reader to get the base64.  It is too bad that DATA_URL doesn't also return the metadata.
