I would leave the browser side out of this CL.

[Matt Giuca, 2016/04/12 06:12:21]

It makes sense to me to have one CL that pipes this all the way from JavaScript
through to the browser; all the non-platform-specific code for share. Otherwise,
how do I know that any of the Mojo stuff is working?

For example, I am getting problems #including ballista.mojom.h from this file
(now that I have moved it into third_party). That needs to be considered before
landing the other part.

Are you suggesting I put this in its own CL or in the Android-specific CL?

[Matt Giuca, 2016/04/12 07:41:12]

OK Done (separated into https://codereview.chromium.org/1880003002 -- maybe will
talk directly to Java but I'm not sure that makes sense given that we eventually
want this to be cross-platform, and also because I don't actually want to write
a BallistaService in Java, just call the send intent methods which are exposed
to C++. But we can discuss that in the next CL.)
