Answer 1

Try this code...

Ti.Media.showCamera({
    success : function(event) {

       if (event.mediaType == Ti.Media.MEDIA_TYPE_PHOTO) {
          // Here you can do whatever you want with the image captured from the camera
          var imgView = Ti.UI.CreateImageView({
             image: event.media,
             width: Ti.UI.SIZE, height: Ti.UI.SIZE
          });
          Ti.UI.currentWindow.add(imgView); // It will be added to the centre of the window if you didn't specify top or left or ...
       } else {
        alert("got the wrong type back =" + event.mediaType);
       }        
    },
    cancel : function() {
       alert("You have cancelled !");
    },
    error : function(error) {
       alert("error");
    },
       saveToPhotoGallery : true,
       allowEditing : true,
       mediaTypes : [Ti.Media.MEDIA_TYPE_PHOTO]
});

You will receive the captured image data via a method of the Callback interface. Callback interface is used to supply image data from a photo capture.

Camera.PictureCallback

onPictureTaken(byte[] data, Camera camera)
{
     ......
     Your code
     ......
}

You can do whatever you want to do with image data here. Means you can set the image to imageview here. You will receive data in bytes. Simply convert it to drawable/bitmap and set that drawable/bitmap to the imageview. Thats it!

For converting bytes to bitmap you can use this link : How to convert byte array to Bitmap

Thanks for all the response ... I have solved this my own.

var image = event.media;

then capture the native path for the image using nativePath

image.nativePath

and then store this path to the application property and reuse this property using Application getString function.
