Post to wall from Android application...
parameters.putString("app_id", mAppId);
parameters.putString("picture", "http://fbrell.com/f8.jpg");
parameters.putString("name", "Facebook Dialog");
parameters.putString("caption", "Reference Documentation");
parameters.putString("description", "Dialogs provide simple interface applications...");
parameters.putString("message", "Facebook Dialogs are easy!");
I have specified above parameters and every time I am getting blank dialog (with title "Post to your wall") - and when I click on "Publish" button - it post correct values on given account... so there is no issue relate to posing parameter values to wall, but I do not know why I am getting balnk dialog!
use simple facebook sdk project it simplifies things a lot. They have created a library project for this
