that depends on how the hardware vendor has implemented the support for it. Opengl es is almost always offloaded to a gpu and java bindings for the same are also available so u can use them in your ui. As far as general android ui is concerned it is rendered using skia,a graphics library,it can be configured to use gpu via opengl but most hardware vendors don't do it. so in general android ui is not rendered using gpu but it depends on hw implementation.....pardon me for english,its not my native language.
