setOnCancelListener and setOnDismissListener is not called for AlertDialog for back button pressed or touch outside

When Touch outside the dialog region Press on back button I'm expecting onDismiss (Or onCancel) will be called. However, both of them are not called. May I know is there anything I'm missing? From AlertDialog setOnDismissListener not working, I thought onCancel will be called when I press back button. But it doesn't work for me. May I know is there anything I had missed out? public class RateAppDi
