// All four of these rankings are sourced from a combination of public app usage
// data sets and Chrome-side metrics about common share targets; the exact
// details of that process are described in go/sh-plus.
//
// These are lists of activities rather than packages, so that multiple share
// targets from the same app can appear in different places in the ranking. This
// is a bit brittle; see https://crbug.com/1222156#c4 for why. Regrettably, the
// mapping from human-readable (app name, action) pairs to activities was done
// by hand; see go/sh-3p-activities for that.
//
// These lists are used to rank which share targets are shown for users with no
// share history. In all cases, only apps actually present on the device are
// shown; these lists control the relative ordering when many of these apps are
// all present at once. Once the user has any share history, ShareRanking will
// use that history rather than these default lists.
//
// You'll notice that this data is split up by "EnUs" and "World"; this is
// because the popularity of apps around the world in general is pretty similar,
// *except* for en-US users, who have pretty major differences. If other locales
// diverge more from the main world list we will need to add more cases here for
// them.
