I am trying to make a class to handle all my interactions with Facebook. I am passing the the Login activity I created to the FacebookConnector object (the object in question) to store the credentials and etc. Please view the video to see what I am dealing with http://www.youtube.com/watch?v=OkHEy9Mh1hc. Below is the FacebookConnector class with the App Id edited out

package it.stick;

private Facebook facebook;

private Activity activity;


/** Saves applications credentials */
public boolean saveCredentials(Facebook facebook){
    Editor editor = activity.getSharedPreferences(KEY, Context.MODE_PRIVATE).edit();
    editor.putString(TOKEN, facebook.getAccessToken());
    editor.putLong(EXPIRES, facebook.getAccessExpires());
    return editor.commit();
}

public boolean restoreCredentials(Facebook facebook){
    SharedPreferences sharedPreferences = activity.getSharedPreferences(KEY, Context.MODE_PRIVATE);
    facebook.setAccessToken(sharedPreferences.getString(TOKEN, null));
    facebook.setAccessExpires(sharedPreferences.getLong(EXPIRES, 0));
    return facebook.isSessionValid();
}

    catch(Exception e){
        showToast("Failed to post to wall. We fucked up :(");
        e.printStackTrace();
    }

    }

    @Override

}

public void showToast(String message){

I have cleared the browser cache and the app data. I have checked the key hash and I have copied and pasted the App ID multiple times into the app.
