Same class with different extends

Question

I have a two classes with the same content, but first class is for android version <honeycomb and extends support library for fragments. Second class for version higher than honeycomb and extends native sdk library. Is it possible to have only one class file but somehow extend it for both?

Answer 1

You can't, but both of them can implement the same Interface, and the class that wants to use these 2 classes will just have to use that interface (This is called the Strategy Pattern). Depending on the version of the OS, you'll return a class or the other when asking for that interface ( Factory Pattern).
