dxie@ can you provide some context?  Does this need to be done for servicification, even if only used in Clank code?

donnd, if you have not started on this, I would like to offer to take it.

Re comment #7, please help migrate this for clank.

tonikitoo@, I did start on this but didn't get very far, so if you'd like to take it that would be great.  Let me know if you'd like help from me, and feel free to assign to yourself.

thanks donnd@. Will make sure to loop you in as reviewer.

[android] Migrate ContextualSearchDelegate using SimpleURLLoader

URLFetcher will stop working with advent of Network Service, and
SimpleURLLoader is the replacement API for most clients.
This CL migrates Android's ContextualSearchDelegate and the
respective unittests away from URLFetcher.
