This is how I retrieve the information stored in shared preference and later am comparing whether username and password exists. If user is logged in I am able to show another activity.
SharedPreferences settings = getSharedPreferences(“logindetails”, 0);
String username = settings.getString("username", "");
String password = settings.getString("password", "");
But now I am trying to retrieve the username and gender of the user and display in my activity.
I am trying to solve this, but not yet found the convincing result.
Can any one help me to get out of my requirement?
Note: I am also seeing the documents of Facebook developer’s page
This is the code I am using to retrieve the user data and display in another activity. What problem am facing is the layout is loaded before the response from the facebook is paresed. I suspect it is because of the use of mAsyncRunner as it takes the control on its own. What I am trying to find out is hwo to parse it before the layout is loaded.

this.facebookConnector = new FacebookConnect(APP_ID, this,

Can anybody please help me?
Finally am able to solve my problem myself.
