why content/android? we don't have content/win or content/mac or content/linux

I'll let Grace comment on this one as I'm just following the convention we
decided downstream, and she will be better able to explain why.

When we start to upstream Java files, we came up with the conclusion that we
will put all the Java files under android in each top directory. The top
directory is defined where the *.gyp is. The Java files will keep the sub
directory structure. In this case, all Java files for content will be under
content/android.

as someone not familiar with android development, can you explain to me what
these java files are used for? are they used when building an application over
content? i.e. will every android embedder of content require these files, or
just content_shell and chrome on android which is in your own repo?

[klobag.chromium, 2012/04/20 17:13:57]

These Java files will be shared by any Android embedder, which includes
content_shell, Chrome for Android and tests.

I see. In that case, how about content/public/android? chrome right now can only
access content/public and content/test. Since content/public is what embedders
are supposed to use, it seems that these files belong there?
