                //do the fetching of user details..
            }
            else

    class LoginretrieveTask extends AsyncTask<Void, Void, Void>

    }

    protected void makeuserdetailsrequest(Session session) {

    }


    @Override

        super.onRestoreInstanceState(savedInstanceState);
        uihelper.onSaveInstanceState(savedInstanceState);
    }
}

Log.e("Sessionstate", ""+state); here showing LOGIN FAILED CLOSED.

and the manifest file

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.primus.taukyresigstration"
    android:versionCode="1"
    android:versionName="1.0" >
