Saving the value of toggle buttons when activity gets destroyed and put them back when activity starts again

Question

enter image description hereGood day, I want to save the value of the toggle buttons when the app exits and put them back when the user starts the app again. I've tried using onSaveInstanceState but it just doesn't work. Any help would be appreciated. Thank you.

    @Override
    protected void onSaveInstanceState(Bundle savedInstanceState) {
        super.onSaveInstanceState(savedInstanceState);
        savedInstanceState.putBoolean("white", white.isChecked());

        savedInstanceState.putBoolean("orange", orange.isChecked());
        savedInstanceState.putBoolean("red", red.isChecked());
        savedInstanceState.putBoolean("blue", blue.isChecked());
        savedInstanceState.putInt("whiteI", whiteI.getVisibility());

Try using SharedPreferences

SharedPreferences savePreferences = getSharedPreferences("pref",MODE_PRIVATE);
SharedPreferences.Editor editPreferences = savePreferences.edit();
editPreferences.putBoolean("white", white.isChecked());
editPreferences.putBoolean("yellow", yellow.isChecked());
editPreferences.putBoolean("orange", orange.isChecked());
editPreferences.putBoolean("red", red.isChecked());
editPreferences.putBoolean("blue", blue.isChecked());
editPreferences.putInt("whiteI", whiteI.getVisibility());
editPreferences.putInt("yellowI", yellowI.getVisibility());
editPreferences.putInt("orangeI", orangeI.getVisibility());
editPreferences.putInt("redI", redI.getVisibility());
editPreferences.putInt("blueI", blueI.getVisibility());
editPreferences.commit();

To retrive data

    white.setChecked(savePreferences.getBoolean("white"));
    yellow.setChecked(savePreferences.getBoolean("yellow"));
    orange.setChecked(savePreferences.getBoolean("orange"));         
    red.setChecked(savePreferences.getBoolean("red"));
    blue.setChecked(savePreferences.getBoolean("blue"));    
    whiteI.setVisibility(savePreferences.getInt("whiteI"));
    yellowI.setVisibility(savePreferences.getInt("yellowI"));
    orangeI.setVisibility(savePreferences.getInt("orangeI"));
    redI.setVisibility(savePreferences.getInt("redI"));
    blueI.setVisibility(savePreferences.getInt("blueI"));
