Does this dependency affect package size or anything else? If it does then maybe
we should also enable it only when the feature is enabled?

[Lambros, 2015/07/14 01:18:17]

It will affect package size, but not very much. Cardboard+protobuf is only about
200KB. We'll have to take this size hit eventually anyway.

If we don't add this dependency now, it means that the Cardboard-related Java
code won't compile. So all the Java implementation will have to be cordoned off
into a separate android/cardboard directory which is only included
conditionally, and none of the trybots will compile it.

I think it's better to take the size hit now, and have the build-bots actually
build and check the Java code, even though it won't be called at runtime. We'll
get the benefit of tools like Lint/FindBugs checking our code.

WDYT?

I agree as long as this doesn't bloat the package very significantly.
