Should I strictly avoid using enums on Android?

Question

I used to define a set of related constants like Bundle keys together in an interface like below:

public interface From{
    String LOGIN_SCREEN         


        

Answer 1

Two facts.

1, Enum is one of the most powerful feature in JAVA.

2, Android phone usually has a LOT of memory.

So my answer is NO. I will use Enum in Android.
