Curious why these and many other android files are here instead of
chrome_browser_android_sources below?

[whywhat, 2015/07/15 12:41:05]

I don't know for sure. Generally, files are filtered out by the _{platform}
suffix (e.g. _android) or directory (e.g. /android/). I assume these files are
listed together with everything else for simplicity.
chrome_browser_android_sources is probably for a few files that don't have
android in the path for some reason but are intended to be android only. I'd say
you need to follow up with stuartmorgan@chromium.org to get more details :)
