Beside URL SCHEME, using the SDK based function is more simple.But it may not be the answer you want.

Remarks: The following information is based on facebook-android SDK 2.0(3.0 is avaliable now)

After running the authorize function (Login Part)(The following is sample code in facebook document)

 facebook.authorize(this, new String[] {}, new DialogListener() {
            @Override
            public void onComplete(Bundle values) {
                SharedPreferences.Editor editor = mPrefs.edit();
                editor.putString("access_token", facebook.getAccessToken());
                editor.putLong("access_expires", facebook.getAccessExpires());
                editor.commit();
            }

            @Override
            public void onFacebookError(FacebookError error) {}

            @Override
            public void onError(DialogError e) {}

            @Override
            public void onCancel() {}
        });
    }

In order to get the access token, just run the following function in SDK 2.0

String access_token=facebook.getAccessToken();

For the userID

public String GetUserID(){
    Bundle params = new Bundle();
    params.putString("fields", "id");
    String resp= "";
    try {
        resp = facebook.request("me", params, "GET");//call the request function in SDK 2.0, using graph api
    } catch (FileNotFoundException e) {
    } catch (MalformedURLException e) {
    } catch (IOException e) {
    }
    try{
        resp = new JSONObject(resp).getString("id");
    }catch(JSONException e1){
    }
    }
    return resp;
};

I think these are the most simply way to get the result, but not using the URL SCHEME.

I hope it can help you.
