nit: Current style does not have "(c)" in a file header.

Our style guide does not allow inheriting multiple non-pure-interface classses.
http://google-styleguide.googlecode.com/svn/trunk/cppguide.xml#Multiple_Inher...

You should do: splitting this class into two parts, modifying this class to own
sub-classes of WebstoreStandaloneInstaller and WebContentsObserver or something
like that.

I didn't know it. Thanks. Done.

Why this part is private while WebstoreStandaloneInstaller methods are
protected?
I think this should be protected too.

[yoshiki, 2013/08/30 09:51:46]

Done.

[hashimoto, 2013/08/30 09:09:37]

How about using GURL::EmptyGURL instead of having this member?

[yoshiki, 2013/08/30 09:51:46]

Done.
