New instance of page would be created when press the Android Back Button

I am testing the Navigation feature on Android simulator, and you can find the environment information below.

This is the scenerio:
Page A --------(push with parameter)—> Page B--------(push to C) ------> Page C
when I stay on page C, I wanna navigate back t page B, there are two options on Android simulator:
1) click arrow icon on the top left corner;
2) click the Android hardware back button;
Everything is all right if I take the first opinion.

But, when I take opinion 2, it seems that a new instance of page B would be created by calling constructor, so the parameters brought from page A could not be available.

What I tried as of now:
use registerBackButtonAction(fn, priority) in app level, user nav.pop(), or return false; the constructor of page B is still called.

I have round-about by keeping the parameters in service, but it is really annoying.

Appreciate for your idea or suggestions.
