//Get Profile Picture from id

publicstaticBitmapgetFacebookProfilePicture(String userID){
    try {
        URL imageURL = newURL("https://graph.facebook.com/" + userID + "/picture?type=large");
        Log.e(TAG,imageURL.toString());
        try {
            bitmap = BitmapFactory.decodeStream(imageURL.openConnection().getInputStream());
        } catch (IOException e) {
            e.printStackTrace();
        }

    } catch (MalformedURLException e) {
        e.printStackTrace();
    }
