Bitmap bitmap = BitmapFactory.decodeFile(uri.getPath());

Simple way to do

This is a simple one line way to do it:

try {
        URL url = new URL("http://....");
        Bitmap image = BitmapFactory.decodeStream(url.openConnection().getInputStream());
    } catch(IOException e) {
        System.out.println(e);
    }
