Could you replace most of this with: "//tools/android/*" ?

[pkotwicz, 2015/09/29 14:24:52]

I am not sure if the intent of the android_tools target is to build all
subdirectories. It currently does not for GYP.

[Yaron, 2015/09/29 16:52:22]

I'm fairly certain it was when we first added it :)
I expect it not matching was an accident

You can't replace it with //tools/android/* because GN does not support
wildcards.

You should not use wildcards in GYP either, because wildcards can cause weird
things to get slurped in :).
