Seems like you don't *need* the real Profile. A BrowserContext can do. You can
pass it into the KioskBridge through
https://cs.chromium.org/chromium/src/components/arc/arc_service_manager.cc?sq...
(where you should add the BrowserContext as parameter).

[Sergey Poromov, 2016/11/23 13:45:33]

There can't be any BrowserContext in components/arc/arc_service_manager due to
violating deps rules.
As well ArcKioskAppService should access to
chrome/browser/chromeos/app_mode/arc/arc_kiosk_app_service.h and that's why it
was moved from there to chrome/browser/chromeos/arc/...
and now it's created by ArcServiceLauncher that doesn't have any information
about Profile/BrowserContext
