SUP HWC: Physical back button (hard key) issue in android

Hi All,

I did a SUP hwc application, and it's working end-to-end fine in iphone.

But problem with Physical back button (hard key) in android device.

Scenario:

Suppose In HWC application, I navigate through screens   A --> B--> C(Create screen)--> D(success screen of C)

Now I am in screen D,

suppose now if I press on Physical back button (hard key) in android device I can see Screen C.

                        if I use MenuItem back button, I will navigate to screen A( which is correct according to our scenario)

It's a big problem in end user perspective.

is there any option to disable the physical back button (hard key) in android device?

Thanks in advance,

Lakshman Balanagu.
