@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main2);
    savedInstanceState.putString("foo", "bar");
}

@Override
public void onRestoreInstanceState(Bundle savedInstanceState) {
  super.onRestoreInstanceState(savedInstanceState);

  String myString = savedInstanceState.getString("foo");

  Log.i("debug", "saved data: " + myString);
}

Im trying to preserve some values in an activity, but i recieve the following error: 06-23 23:09:44.038: E/AndroidRuntime(17584): java.lang.RuntimeException: Unable to start activity ComponentInfo{se.johanberntsson.activitytest/se.johanberntsson.activitytest.TestActivity}: java.lang.NullPointerException

What did I miss here? Thanks
