In your acticity override onSaveInstanceState and onRestoreInstanceState. These methods will allow you to save data into a Bundle You can also save data to Preferences. In all of my applications I override both onSaveInstanceState and onRestoreInstanceState to save and load values to a Bundle. I also save data to preferences in onPause and load preferences in onResume. Also in onCreate(Bundle savedInstanceState) I do a check like this

    if(savedInstanceState != null)
    {
        m_mainView.restoreInstanceState(savedInstanceState);
    }
    else
    {
        m_mainView.loadGameFromDatabase(getPreferences(MODE_PRIVATE));
    }

These practices have always worked for me.
