Answer 1

you need to use the onSavedInstanceState method to store all the value to its parameter is has that is bundle

@Override
    public void onSaveInstanceState(Bundle outState, PersistableBundle outPersistentState) {
        super.onSaveInstanceState(outState, outPersistentState);
        outPersistentState.putBoolean("key",value);
    }

and use

@Override
    protected void onRestoreInstanceState(Bundle savedInstanceState) {
        super.onRestoreInstanceState(savedInstanceState);
        savedInstanceState.getBoolean("key");
    } 

to retrive and set the value to view objects it will handles the screen rotations
