Answer 3

If I'm not mistaken when the application remains open for a long time, the data will be released by the Android OS, and while the stopiong operation will call "onSaveInstanceState", and when can I save the searchritiera in this method and whether it will return when " onRestoreInstanceState "caused by?

private static SearchCriteria searchCriteria;


@Override 
    public void onSaveInstanceState(Bundle outState) 
    {
        outState.putSerializable(WLConstants.SEARCH_CRITERIA, searchCriteria);
        super.onSaveInstanceState(outState); 
    }
    @Override
    protected void onRestoreInstanceState(Bundle savedInstanceState) {
        if(savedInstanceState != null){
            searchCriteria = (SearchCriteria)
            savedInstanceState.getSerializable(WLConstants.SEARCH_CRITERIA);
        }
        super.onRestoreInstanceState(savedInstanceState);
    }
