Please add a comment:

 // On android, NFC is implemented as a Java mojo service.

[shalamov, 2016/04/26 21:56:52]

Done.

   GetServiceRegistry()->AddService<device::NFC>(
       base::Bind(&device::NFCImpl::Create));

This line doesn't seem to exist at tip of tree; I see that this is a dependent
patch, several layers deep.

Are you planning on landing
https://codereview.chromium.org/1912363002/diff/120001/content/browser/frame_...
first? Should I review that one to?

[shalamov, 2016/04/26 21:56:52]

Yes, I'm planning to land https://crrev.com/1912363002 first. Reilly Grant,
helped to review that CL. If you have time, please take a look.
