Answer 2

You Can Do Like This.

public static void getuserdata() throws JSONException {
    String Facebook = readT("https://graph.facebook.com/me?access_token="+mFacebook.getAccessToken()+"&fields=id,username)".replace(" ","%20"));
    try
    {
        JSONObject jsonobj = new JSONObject(Facebook);
        fb_id = jsonobj.getString("id");
        fb_username = fb_fname+" "+fb_lname;
        Log.e("..fb_username..........", fb_username);
    }
    catch (JSONException e) 
    {
        e.printStackTrace();
    }

}
