The features are enabled once the onCreate() methood is executed for the first time, but after i do a screen rotation none of the features get saved, even though I've overridden the onSaveInstanceState() method and I've also tried using the onRestoreInstanceState() method. Kindly help me out.
I'll attach the code below. Activity file
