Wifi statemachine starts P2p statemachine; which uses network management
service to (i.e. netd) to start p2p0 interface. But it only gets a
reference to network management service in conenctivityServiceReady().
Calling that later means there's a chance of a race between this
thread's setting of the network manager, and P2p statemachine thread's
usage of the same.

We now have the activity manager kill long-running processes
during idle maintanence.
This involved adding some more information to the activity manager
about the current memory state, so that it could know if it really
should bother killing anything. While doing this, I also improved
how we determine when memory is getting low by better ignoring cases
where processes are going away for other reasons (such as now idle
maintenance). We now won't raise our memory state if either a process
is going away because we wanted it gone for another reason or the
total number of processes is not decreasing.
The idle maintanence killing also uses new per-process information
about whether the process has ever gone into the cached state since
the last idle maintenance, and the initial pss and current pss size
over its run time.

1. Now a user state has ins own spooler since the spooler app is
running per user. The user state registers an observer for the state
of the spooler to get information needed to orchestrate unbinding
from print serivces that have no work and eventually unbinding from
the spooler when all no service has any work.
2. Abstracted a remote print service from the perspective of the system
in a class that is transparently managing binding and unbinding to
the remote instance.
3. Abstracted the remote print spooler to transparently manage binding
and unbinding to the remote instance when there is work and when
there is no work, respectively.
4. Cleaned up the print document adapter (ex-PrintAdapter) APIs to
enable implementing the all callbacks on a thread of choice. If
the document is really small, using the main thread makes sense.
Now if an app that does not need the UI state to layout the printed
content, it can schedule all the work for allocating resources, laying
out, writing, and releasing resources on a dedicated thread.
5. Added info class for the printed document that is now propagated
the the print services. A print service gets an instance of a
new document class that encapsulates the document info and a method
to access the document's data.
6. Added APIs for describing the type of a document to the new document
info class. This allows a print service to do smarts based on the
doc type. For now we have only photo and document types.
7. Renamed the systemReady method for system services that implement
it with different semantics to systemRunning. Such methods assume
the the service can run third-party code which is not the same as
systemReady.
8. Cleaned up the print job configuration activity.
9. Sigh... code clean up here and there. Factoring out classes to
improve readability.

System server always forks from Zygote so we no longer need
the system_server executable which was probably broken anyhow.
This makes the initialization sequence slightly more intelligible.
Likewise, we don't need the GrimReaper anymore because init
will automatically take care of restarting the system when the
service manager dies.

The MountService will take 2 minutes to time out trying to

Adds an optimization for checking whether a looper is stuck,
with a new Looper method to see if its thread is currently
idle. This will allow us to put a large number of loopers
in the monitor efficiently, since we generally won't have to
do a context switch on each of them (since most looper threads
spend most of their time idle waiting for work).
Also change things so the system process's main thread
is actually running on the main thread. Because Jeff
asked for this, and who am I to argue? :)

1. The scheduling was relying on receiving battery level broadcasts
which however are not sent if the device is asleep. The maintenance
window was not bound and we could miss a frame if the user did
not interact the device longer than the min time between two
maintenance windows.
2. Hide the idle maintenance intents since this will be rewritten
to user services.

This introduces four generic thread that services can
use in the system process:
- Background: part of the framework for all processes, for
work that is purely background (no timing constraint).
- UI: for time-critical display of UI.
- Foreground: normal foreground work.
- IO: performing IO operations.
I went through and moved services into these threads in the
places I felt relatively comfortable about understanding what
they are doing. There are still a bunch more we need to look
at -- lots of networking stuff left, 3 or so different native
daemon connectors which I didn't know how much would block,
audio stuff, etc.
Also updated Watchdog to be aware of and check these new
threads, with a new API for other threads to also participate
in this checking.

When the Android runtime starts, the system preloads a series of assets
in the Zygote process. These assets are shared across all processes.
Unfortunately, each one of these assets is later uploaded in its own
OpenGL texture, once per process. This wastes memory and generates
unnecessary OpenGL state changes.
This CL introduces an asset server that provides an atlas to all processes.
Note: bitmaps used by skia shaders are *not* sampled from the atlas.
It's an uncommon use case and would require extra texture transforms
in the GL shaders.
WHAT IS THE ASSETS ATLAS
The "assets atlas" is a single, shareable graphic buffer that contains
all the system's preloaded bitmap drawables (this includes 9-patches.)
The atlas is made of two distinct objects: the graphic buffer that
contains the actual pixels and the map which indicates where each
preloaded bitmap can be found in the atlas (essentially a pair of
x and y coordinates.)
HOW IS THE ASSETS ATLAS GENERATED
Because we need to support a wide variety of devices and because it
is easy to change the list of preloaded drawables, the atlas is
generated at runtime, during the startup phase of the system process.
There are several steps that lead to the atlas generation:
1. If the device is booting for the first time, or if the device was
updated, we need to find the best atlas configuration. To do so,
the atlas service tries a number of width, height and algorithm
variations that allows us to pack as many assets as possible while
using as little memory as possible. Once a best configuration is found,
it gets written to disk in /data/system/framework_atlas
2. Given a best configuration (algorithm variant, dimensions and
number of bitmaps that can be packed in the atlas), the atlas service
packs all the preloaded bitmaps into a single graphic buffer object.
3. The packing is done using Skia in a temporary native bitmap. The
Skia bitmap is then copied into the graphic buffer using OpenGL ES
to benefit from texture swizzling.
HOW PROCESSES USE THE ATLAS
Whenever a process' hardware renderer initializes its EGL context,
it queries the atlas service for the graphic buffer and the map.
It is important to remember that both the context and the map will
be valid for the lifetime of the hardware renderer (if the system
process goes down, all apps get killed as well.)
Every time the hardware renderer needs to render a bitmap, it first
checks whether the bitmap can be found in the assets atlas. When
the bitmap is part of the atlas, texture coordinates are remapped
appropriately before rendering.

SystemServer is currently a monolithic class that brings up key system
services. This change is the first phase of refactoring it to be more
configurable. Specifically, it adds a set of on/off switches used to control
startup of individual services. Future plans include finer grained controls
and a more explicit and consistent startup sequence for these services.

The Activity Manager sets up a permission-guarded domain socket, which
debuggerd connects to when a crash happens. If this is successful,
the daemon then mirrors the logged crash report to that socket, then
closes it.
The Activity Manager parses the native crash dump supplied by debuggerd
and forwards it to the standard app-crashed code. The UX result is
that users now see the normal "app has stopped unexpectedly" dialog
with "report" and "okay" options for native crashes, not just for
DVM-mediated crashes.

It is beneficial that there is a mechanism on the platform
to notify applications whether it is safe to perform somehow
expensive operations while the user is not using the device.
Thus, user experience will not be degraded. An example is
discarding of unused blocks on a mounted file system instead
of doing this on every write operation.

vibrator usage (since I had to be in the vibrator code anyway

The service itself is only half-done. Currently no API to
retrieve the data (which once there will allow us to show you
which apps are currently causing the GPS to run and who has
recently accessed your location), it doesn't persist its data
like it should, and no way to tell it to reject app requests
for various operations.

Clearly isolated the DreamManagerService and DreamController
responsibilities. DreamManagerService contains just enough logic to
manage the global synchronous behaviors. All of the asynchronous
behaviors are in DreamController.
Added a new PowerManager function called nap() to request the device
to start napping. If it is a good time to nap, then the
PowerManagerService will call startDream() on the DreamManagerService
to start dreaming.
Fixed a possible multi-user issue by explicitly tracking for
which user a dream service is being started and stopping dreams
when the current user changes. The user id is also passed to
bindService() to ensure that the dream has the right environment.
Fix interactions with docks and the UI mode manager. It is
important that we always send the ACTION_DOCK_EVENT broadcast
to the system so that it can configure audio routing and the like.
When docked, the UI mode manager starts a dock app if there is
one, otherwise it starts a dream.
This change resolves issues with dreams started for reasons other
than a user activity timeout.

JB has introduced LockSettingsService. When the phone is
upgrading from ICS, that used another way to store lock
settings, the LockSettingsService needs to import these
settings to store in its database. This happens when the
systemReady() method of this class is called by SystemServer.
The problem resides in the fact that the
DevicePolicyManagerService actually needs to access the
LockSettingsService during its systemReady() initialization,
causing invalid values to be read by it which propagates and
ends up causing a invalid return in the method
isActivePasswordSufficient.
If user had a Google corporate account that enforces password
related policies through Google Apps Device Policy (GADP) app
in ICS, when he upgrades to JB, the GADP will throw a
notification saying that the password doesn't meet the required
policies and needs to be changed, incorrectly, since it wasn't
touched during upgrade.
This fix initializes the LockSettingsService before the
DevicePolicyManagerService, which is the correct way since
the latter uses the first in its initialization. This prevents
this issue to happen, and probably future issues, depending
on the way that LockSettingsService evolves.

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.
