Hello,

How you decided “MASTER_KEY” string. Can it be any string. What if hacker reverse engineer your code and know about this string? can he get data stored securely on device?

Hi,

I have two queries regarding clean architecture, which you describe in this story.

1. Let say if I have class ”X” in library and there is method Logout() to logout in that class. Now If I have to call this method should I call this method in Activity(UI ) itself or create a use case and then route…

Ok. So variance needed for type safety. It can be covariance , contravariance and invariance. is it true?

Here i can declare list of Number and replace it first item with any int, float or double value right?

Why at all we need all these variance , just for sake of using same variable assignment. Could you please tell more use cases where you need to use variance and you can’t just skip these variances(invariance,contravariance, covariance)

Can we move code written in onDestroy() to onStop() , because some time onDestroy() not called when activity destroyed.

Which architecture is best MVP or MVVM. What will be criteria or guideline which help in deciding architecture out of these two.
