Maybe we could firstly focus on the actully build command:

I didn't see the libweb_contents_delegate_android.a was linked when build
libxwalkcore.so,and the libweb_contents_delegate_android.a depends on
libbase.a. So,maybe I understand wrong here.
Thanks,Gary

It is still hard to figure out what you are trying to do and why;
basically if you are replacing existing functionality in a layer as low
as base/ you are in uncharted territory. From what I can understand you
basically need option 2 above, as hard as it may be.
