This should default to (is_android && is_offical_build) (i.e., we don't want
this to be true on other platforms).

Done.

Can you make this:

assert(!enable_resource_whitelist_generation || is_android, "resource whitelist
generation only works on android")

?

If you do that, then you can get rid of the if (is_android && ) part of all of
your other checks.

Done.
