            ImageView imageView = (ImageView) findViewById(R.id.imgView);
            imageView.setImageBitmap(BitmapFactory.decodeFile(picturePath));
            imgFile = new File(picturePath);

        }
    }

u should pass the url of image in ur input stream.

InputStream is = (InputStream) new URL(urlofimage).getContent();

return BitmapFactory.decodeStream(is);
