I want complete, end-to-end sandboxes, including for: - Android apps - Chrome extensions - System apps ... etc. These should be capable of providing fake data to the app (e.g. simulating no contacts, no working internet, or a fake GPS location), and trying to break out should be an app store ToS violation.
