Android cannot connect HttpURLConnection to get Bitmap

I'm trying to get Bitmap from URL. I use the methos:

public static Bitmap getBitmapFromURL(String src) {
    try {

            URL url = new URL(src);
            HttpURLConnection connection = (HttpURLConnection) url.openConnection();
            connection.setDoInput(true);
            connection.connect();
            InputStream input = connection.getInputStream();
            Bitmap myBitmap = BitmapFactory.decodeStream(input);
            return myBitmap;
    } catch (IOException e) {
        e.printStackTrace();
        return null;
    }
}

But I cannot pass the line: "connection.connect();". Is there sth which I'm missing? How can I connect()?

My string src = "http://ift.tt/19cwTCl"

I read that i should " This should be used in AsyncTask derived Class.". How to do it?
