We don't need above two methods, right?, there is no warning?

[Yaron, 2016/05/03 20:14:48]

the chrome case does need them - note the callbacks passed.

[michaelbai, 2016/05/03 20:54:01]

I see, you changed it to call the chrome one, but If you use way in clank, you
basically save one copy of these methods, but it is trivial.

[Yaron, 2016/05/04 13:07:44]

Ya, understood but I removed the clank ones. We could do a follow-up CL to
remove the callbacks from the chrome::android ones.
