From 474c616e981c60bcfc05114b4823b9176178240d Mon Sep 17 00:00:00 2001
From: Andy Wickham <awickham@google.com>
Date: Mon, 3 May 2021 18:26:44 -0700
Subject: [PATCH] Adds AllSetActivity in Launcher.

Mostly copied from its location in Tips.

Some exceptions:
 - Accent color (used for the icon at the top and link text)
   is derived from intent extras to match the rest of SUW.
   If needed, we could also pass other colors this way;
   currently they just use default light/dark mode colors.
 - Currently there is no animation in the middle. Not sure
   if one is expected, but we can add it later if so.

Bug: 184722307
Test: Manually passing arbitrary colors via adb:
adb shell am start -a com.android.quickstep.action.GESTURE_ONBOARDING_ALL_SET --ei accent_color_dark_mode -2134901760 --ei accent_color_light_mode 2147418112
