Request to put this Activity in a mode where the user is locked to the current task. This will prevent the user from launching other apps, going to settings, or reaching the home screen. If Android.App.Admin.DevicePolicyManager.IsLockTaskPermitted(string) returns true for this component then the app will go directly into Lock Task mode. The user will not be able to exit this mode until Activity.StopLockTask is called. If Android.App.Admin.DevicePolicyManager.IsLockTaskPermitted(string) returns false then the system will prompt the user with a dialog requesting permission to enter this mode. When entered through this method the user can exit at any time through an action described by the request dialog. Calling stopLockTask will also exit the mode.
