Why do Singletons need an empty default constructor?

[Isabaellchen]

Sorry for piling onto the empty default constructor debate, but this is something i do not understand.

I do understand that you want to make the code explicit as to where classes get initialized, but i do not understand why this has to be the case for classes that are annotated as Singletons, since there is only that one particular instance that i want to create. If it is not too much to ask maybe someone could give an explanation to this?

I think you want google/dagger
