The way it should have been, and with the new recents enter animation
the way it must be.
Added a new method to retrieve this thumbnail, since it would be less
efficient to use the existing API (which always returns the "base"
thumbnail). Probably at some point that existing API should be tweaked
to always return the top thumbnail instead, but that is for a later time.
Also removed code that would clear the thumbnail associated with an
activity when it is resumed. I don't think there should ever be a
reason to clear a thumbnail -- it's much better to have *something*
for the task, even if it is a little out of date.

Store device policy information for each user and apply them when user switches.
Global proxy can only be controlled by owner.
Camera restriction applies to all users, if any one has an admin that disables it.
Storage encryption can only be controlled by owner, although other users can query the state.
Wipe data will only remove the user if non-zero, wipe the device, if zero.

The current MTP kernel driver at /dev/mtp_usb is exclusive, meaning
only one process can have it open. In addition, each MTP session
with a desktop requires unique object IDs, which doesn't hold true
across users on the device.
To solve these two issues, when switching users we cycle the USB host
stack to disconnect both local and remote MTP connections, giving the
new user's media process a chance to claim /dev/mtp_usb, and causing
the desktop to initiate a new MTP session.
This change also allows BroadcastReceivers to registerReceiver()
allow retrieval of a current sticky broadcast. Adds a system property
to override maximum users. Removes MOUNTED broadcasts for secondary
users. Allows INTERACT_ACROSS_USERS to getCurrentUser().

* Don't mutate original intents when adding default flags.
* Add the relevant flags to the array returned by getIntents() such
that it can be used directly in a call to startActivities or
similar.
* Deep copy the component intents when building an intent array for

Add a new call to the activity manager to tell it when the activity
is resumed, so it can mark its state as dirty then instead of when
it first tries to create it.
Also tweak things to update the LRU list for the upcoming activity
at the point we start pausing the current activity, to avoid an
inefficiency where we may decide to kill the process of the upcoming
activity if it is at the end of the LRU list.

- New public APIs to find out when a user goes to the foreground,
background, and is first initializing.
- New activity manager callback to be involved in the user switch
process, allowing other services to let it know when it is safe
to stop freezing the screen.
- Wallpaper service now implements this to handle its user switch,
telling the activity manager when it is done. (Currently this is
only handling the old wallpaper going away, we need a little more
work to correctly wait for the new wallpaper to get added.)
- Lock screen now implements the callback to do its user switch. It
also now locks itself when this happens, instead of relying on
some other entity making sure it is locked.
- Pre-boot broadcasts now go to all users.
- WallpaperManager now has an API to find out if a named wallpaper is
in use by any users.

When building external storage paths, always include user in path
to enable cross-user paths and aid debugging.
Each Zygote process continues to only have access to the appropriate
user-specific emulated storage through bind mounts. A second set of
mounts continue supporting legacy /sdcard-style paths. For example,
a process running as owner has these mount points:
/storage/emulated_legacy
/storage/emulated_legacy/Android/obb
/storage/emulated/0
/storage/emulated/obb
Since Environment is created before Zygote forks, we need to update
its internal paths after each process launches.

- New (hidden) isUserRunning() API.
- Maintain LRU list of visited users.
- New FLAG_IS_DATA_ONLY for ApplicationInfo.
- Clean up pending intent records when force-stopping a user (or package).
(Also fixes bug #6880627: PendingIntent.getService() returns stale
intent of force stopped app)
- Fix force-stopping when installing an app to do the force-stop across
all users for that app.
- When selecting which processes to kill during a force stop, do this
based on the actual packages loaded in the process, not just process
name matching.
- You can now use --user option in am when starting activities, services,
and instrumentation.
- The am --user option accepts "current" and "all" as arguments.
- The pm uninstall command now uninstalls for all users, so it matches
the semantics of the install command.
- PhoneWindowManager now explicitly says to start home in the current
user.
- Activity manager call to retrieve the MIME type from a content provider
now takes a user argument, so it will direct this to the proper user.
- The package manager uninstall paths are now implemented around
PackageSetting, not PackageParser.Package. This allows them to work
even if the application's apk has been removed (in which case it only
exists as a PackageSetting, not the PackageParser.Package parsed from
the apk).

New API to register as an explicit user, which allows you to

This patch introduces the ability to create a Context that
is bound to a Display. The context gets its configuration and
metrics from that display and is able to provide a WindowManager
that is bound to the display.
To make it easier to use, we also add a new kind of Dialog
called a Presentation. Presentation takes care of setting
up the context as needed and watches for significant changes
in the display configuration. If the display is removed,
then the presentation simply dismisses itself.

Replaced all remaining places that used it with explicit user
specification.
While doing this, I ran into stuff that was creating PendingIntent
objects (that now need to specify the explicit user they are for),
which are also posting notifications... but have no way to specify
the user for the notification.
So the notification manager in the system process now also gets a
formal concept of a user associated with the notification, which
is passed in to all the necessary aidl calls. I also removed the
old deprecated aidl interface for posting/cancelling notifications,
since we now always need a user supplied.
There is more work that needs to be done here, though. For example
I think we need to be able to specify USER_ALL for a notification that
should be shown to all users (such as low storage or low battery).
Along with that, the PendingIntent creation needs to be tweaked to
be able to handle USER_CURRENT by evaluating the user at the point the
pending intent is sent.
That's for another change, however.

You can now use ALL and CURRENT when sending broadcasts, to specify
where the broadcast goes.
Sticky broadcasts are now correctly separated per user, and registered
receivers are filtered based on the requested target user.
New Context APIs for more kinds of sending broadcasts as users.
Updating a bunch of system code that sends broadcasts to explicitly
specify which user the broadcast goes to.
Made a single version of the code for interpreting the requested
target user ID that all entries to activity manager (start activity,
send broadcast, start service) use.

Split the DisplayManager into two parts. One part is bound
to a Context and takes care of Display compatibility and
caching Display objects on behalf of the Context. The other
part is global and takes care of communicating with the
DisplayManagerService, handling callbacks, and caching
DisplayInfo objects on behalf of the process.
Implemented support for enumerating Displays and getting
callbacks when displays are added, removed or changed.
Elaborated the roles of DisplayManagerService, DisplayAdapter,
and DisplayDevice. We now support having multiple display
adapters registered, each of which can register multiple display
devices and configure them dynamically.
Added an OverlayDisplayAdapter which is used to simulate
secondary displays by means of overlay windows. Different
configurations of overlays can be selected using a new
setting in the Developer Settings panel. The overlays can
be repositioned and resized by the user for convenience.
At the moment, all displays are mirrors of display 0 and
no display transformations are applied. This will be improved
in future patches.
Refactored the way that the window manager creates its threads.
The OverlayDisplayAdapter needs to be able to use hardware
acceleration so it must share the same UI thread as the Keyguard
and window manager policy. We now handle this explicitly as
part of starting up the system server. This puts us in a
better position to consider how we might want to share (or not
share) Loopers among components.
Overlay displays are disabled when in safe mode or in only-core
mode to reduce the number of dependencies started in these modes.

The activity manager now keeps track of which users are running.
Initially, only user 0 is running.
When you switch to another user, that user is started so it is
running. It is only at this point that BOOT_COMPLETED is sent
for that user and it is allowed to execute anything.
You can stop any user except user 0, which brings it back to the
same state as when you first boot the device. This is also used
to be able to more cleaning delete a user, by first stopping it
before removing its data.
There is a new broadcast ACTION_USER_STOPPED sent when a user is
stopped; system services need to handle this like they currently
handle ACTION_PACKAGE_RESTARTED when individual packages are
restarted.
