Android Question How to avoid creating a false Singleton class?

(I might even force myself a little, I know )

I have developed a class, I will publish, but it goes used as a Singleton class, in the sense that there must be only one instance of it.

I should better study the module Scales by Klaus, although it needs initialization, it is a module!

Or should I create a library?

(Finally, I have not tested it in depth and probably the descriptions in English that I have used are are far from perfect).

Thanks
