d86b8fea43ebb6e5c31691b44d8ceb0d8d3c9072 03-Jun-2017 Jeff Sharkey <jsharkey@android.com> Annotate @SystemApi with required permissions.

Most @SystemApi methods should be protected with system (or higher)
permissions, so annotate common methods with @RequiresPermission to
make automatic verification easier.

Verification is really only relevant when calling into system
services (where permissions checking can happen on the other side of
a Binder call), so annotate managers with the new @SystemService
annotation, which is now automatically documented.

This is purely a docs change; no logic changes are being made.

This service connects through the print manager to the print spooler:

PrintSpooler.AddPrintersActivity <-> PrintManager <-> PrintManagerService <-> UserState <-> RemotePrintServiceRecommendationService <-> PrintRecommendationService <-> PrintRecommendationServiceImpl

Hence there is a lot of mindless plumming.

The actual changes are only in the AddPrintersActivity which is extended
to show another list of services: The recommended services.

The PrintServiceRecommendationService is based on the experimenal print
service stubs provider. This provider was contributed the Android by
Mopria. As this services uses Android own network discovery service most
code from the experimental provider goes away. In fact the only logic
left over is the selections of mdns-txt fields to look at and the
printer vendor configuration.

This relies on the Android MDNS to get fixed (Bug: 27696905). This also
does not deal with how to update the recommendation service.

layout changes

Before we updated the print preview when the paper size changed but not
when the page ranges changed. This is not consistent. We always change.

Also if there is a change to the options that changes the layout (i.e.
papersize, orientation, minMargins) then clear the selected ranges as
this does not make sense anymore.

This also fixes a bug that when having pages selected while we reduce
the number of pages in the preview we got a NPE.

Bonus: do not constantly re-update the options UI when range or copies
text is updated.

66c96591e2ddb464c67e60dbf4193ef4ec8a620b 24-Feb-2016 Philip P. Moltmann <moltmann@google.com> Add "app printer activity" and always keep the print service state
updated. Also fiddle with the UI to use more standard values.

To be sure the print service state alwasy updated I changed
PrintManager.getPrintServices to return a loader which just wraps a
registerListener/getList/removeListener combo.

I also added a new function to enabled/disable a print service to be
keep all updating logic inside the PrintManagerService->UserState.

Then I changed all code to use this new interface.

Detailed comments:

PrintServiceInfo:
- I had to add the enabled state to the PrintServiceInfo as some users
of PrintManager.getPrintServices want all services but then display
different data depending on the enabled state. Of course I could have
created two PrintManager.getPrintServices-loaders to load the two
separate list of services. I think it is much easier to add this
property though. It is updated every time new data is returned to the
PrintManager.getPrintServices-loader.

AddPrinterActivity:
- This is shown as a dialog-style overlay to indicate that the user will
return to the select-printers activity. It contains of three list that
are updated via separate loaders.
- The recommended services will be added later to keep this path set
small.

PrintActivity:
- There are two small places where we have to update the data when we
get a new list of print services.
- In very, very rare conditions it can happen that the print service
of the current printer gains or looses the "advancedOptions"
activity
- If we have no enabled print services we want to show "Add printer"
instead of "All printers...".
- Also the print registry is not the only loader anymore, hence we have
to assign loader ids to it to not conflict with the other loaders in
this activity.
- Small bug in onPrintersChanged: If a printer is selected and the print
service of this printer gets disabled the holder goes into "removed"
state which disables the printer. When the print service is then
enabled again, we forgot to re-enable the holder.

PrinterRegistry:
- The registry assumed that the FusedPrinterProvider was the only loader
in the activity. This is not true anymore, hence it has to assign the
appropriate loader ids.
- The FusedPrinterProvider has an internal loader, hence we have to
forward a loader Id into it.
- The PrintRegistry is only called backed for a single loader, hence no
need to check the loader-id.

SelectPrinterActivity:
- The AddPrinterDialog was removed as we now have the
AddPrinterActivity.
- Added a loader for the enabled services to update the empty state.
- Added dedicated loader Id for the PrinterRegistry again.
- If we have no enabled services, the SelectPrinterActivity chainloads
the AddPrinterActivity as this is the only thing the user can do
anyway. "Save a click". This should only happen when the activity is
create the first time.
- Moved the "add printer" from the menu item to the list of printers as
suggested by UX and Zach.

PrintManagerService, UserState and IPrintManagerParamtersTest:
- As the only place where the print service state is updated is now the
userstate, we have no more sychronization problems. Whohoo.
- The users can now register for changes to the print services similar
as they can register for changes to the print jobs.
- UserState.getPrintServices is the only function can exposes any
knowledge of the print services to the outside world.

Similar to first patch, but now using new "rethrowFromSystemServer()"
method which internally translates DeadObjectException into
DeadSystemException. New logic over in Log.printlns() now
suppresses the DeadSystemException stack traces, since they're
misleading and just added pressure to the precious log buffer space.

Add some extra RuntimeInit checks to suppress logging-about-logging
when the system server is dead.

An app might suggest certain attribute for an print job. This patch
fixes

- PrintActivity should not silently overwrite the attributes with

- Handle duplex mode in PrintAttributes similar to the other attributes.
I.e. have an "unset" value (0). This is an API change. But the only
use case for PrintAttributes was to pass them to print() and thereby
the PrintActivity. This was broken (see above), hence we are changing
and API that could have never been used.

Historically, we were allowing an app that prints to specify that
the printed document has zero pages. While this does not make any
sense we should keep the behavior as people may have apps that do
that. This change fixes this issue and now we treat zero the same
way as undefined page count and ask the app to write all pages to
check the written PDF for the page count.

This change adds the pring preview part of the new print UX. The
UI has two parts, the top section is the print options and the
bottom section print preview with a list of pages. The user can
interact only with one of them. When print options are expanded
they cover the preview content and a scrim is laid out on top of
the preview. Tapping the scrim collapses the print options. When
the user types in page ranges and closes the options to look at
the preview, the latter is updated to show only these pages. In
the list of pages the user can further prune pages by deselecting
them.

1. Implemented the advanced printer options integration. Now a print service
may declare an advanced print options activity which may be launched by
the user if the current printer supports advanced print options. These options
are visible only to the print service that added them and it is the only party
that will interpret the options.

2. Fixed a couple of bugs in the saved print jobs parsing. One was that if there
are more than one page range, a half of the print job properties was not
properly parsed. The other was that the media size constructor was using
incorrect argument order, thus creating a media size with wring width.

3. Fixed and edge case where old print jobs and their docs can get stuck in
the spooler. If the app did not write the requested pages we were not showing
an error message, rather just finish the activity without canceling the print
job and this print job is stuck in the spooler. Now we show an error message
and the user may retry, cancel. If the user cancels the print job is also
cancelled, thus no leftover in the spooler.

4. Fixed the background color of the print dialog to meet UX spec.

858a1850e2e1c4516129d27ecdf54aaeade606ca 18-Oct-2013 Svetoslav Ganov <svetoslavganov@google.com> Hide the print dialog if the printing activity is destroyed.

1. For an app to print it creates a PrintDocumentAdapter implementation
which is passed to the print dialog activity. If the activity that
created the adapter is destroyed then the adapter, which may rely on
the activity state, may be in an invalid state. For example, an app
creates an adapter and calls print resuting in the app activity and
the print dialog activity being stacked. Now the user rotates the
device which triggers the recreating of the activity stack (assume the
app does not handle rotation). The recreated print dialog activity
receives the intent that originally created it with containing the
adapter that was constructed in the context of the old, now destroyed,
app activity instance.

To handle this we are limiting an app to be able to print only from
and activity and when this activity is destroyed we mark the adapter
as invalid which will result in hiding the print dialog activity. Note
that if the app process is killed we already handle this in the print
dialog activiy by registering a death recipient on the adapter binder.

2. In the PrintManager.PrintDocumentAdapterDelegate some of the state is
accessed only on the main thread and some from miltiple threads. The
code was trying to avoid locking for state that is not accessed by
multiple threads but this is error prone and the benefit does not
justify the complexity and added fragility. Now grabbing a lock all
the time.

3. The PrintJobConfigActivity waits for it to bind to the print spooler
service before instantiating its print controller and editor. However,
these can be accessed by invoking some of the activity cycle callbacks.
This change is adding null checks for the case where the activity
callbacks are called before the binding to the spooler is completed.

2. The listeners for observing the state of print jobs may be called even

unregisretes the callback and on the next loop the notification message
is handled.

When a print service is disabled we assume all print jobs for it failed as we have
no way to know what happens to them. However we are also failing created print jobs,
i.e. ones not given to the service. Such jobs are in process of construction and
the print dialog is up. We should not fail such jobs as the dialog can still modify
their state and potentially select a print from a different service. Therefore, we
leave them alone and they will be failed if when constructed are passed to a
disabled/uninstalled service.

7bfbbcb04bf4ba8f3069b2df136f708c9849bacf 10-Oct-2013 Svetoslav <svetoslavganov@google.com> Refactor how the print dialog activity is started.

1. Before the print job activity was started asyncronously with
respect to the print call on to the print manager. This was
creating a situation where the starting activity may finish
before the print dialog appears which may lead to an orphaned
print document adapter with no data to print (as the UI is
is gone), or strange behaviors where the print dialog starts
on as a separate task.

To address this the pending intent for starting the print
dialog is not started by the print spooler since we cannot
call into it synchronously as we have to start its process
and bind to the spooler service which leads to jankyness in
the client app. Now the pending intent is created by the
print manager service in the synchronous print call so
from an app's perspective calling print starts the activity.

The side effect of this design is that the print dialog
activity may start before the system is bound to the spooler
service. In such a case the print activity cannot start
poking the print spooler state as the system registers
callback to observe the spooler state. To address this
the print spooler activity disables the UI and also binds
to the spooler service which happenes immediately after it
is started. As soon as the print dialog binds to the
service it starts the UI.

2. Fixed an bug in the printer adapter of the print dialog that
was leading to a crash if the only item in the adater is the
all pritners option and it is selected.

3. Piping the package name that started the printing so we can
pass it to the storage UI as a hint to open the last location
the app used.

While printing the app gets callbacks to do a layout and a write. Since
these operations can take a very long time they are implemented in a async
fashion. For example, if there is a layout request while we are still doing
a layout, we ask the application to cancel the previous layout. The problem
was that we were not waiting for the cancellation result before calling
the subsequent layout. Hence, the app ends up having to do two layouts at
the same time which breaks the printing contract. Same for write.

1. Initially we have a single printer, the fake PDF printer, and
wait for printers to be discovered. This printer was handling
only a couple of media sizes. Hence, if the app provides a
media size hint and the PDF printer does not support it, we
were essentially ignoring the suggested media size since it
was not supported by the selected printer and we fell back to
the default paper size for that printer. The fake PDF printer
should support all predefined media sizes.

2. The list of available paper sizes was shown in the order they
are added ignoring the current locale. It is much better user
experience if the media sizes used in the current locale are
shown at the top and all others after that. Also the media
sizes for the current locale should be alphabetically ordered
so the user can quickly find the desired one.

3. The orientation was reset on media size or printer change.

dd68da2741fa63070d5ad206020dcccb9f429a5a 27-Sep-2013 Svetoslav Ganov <svetoslavganov@google.com> Print job files and print job records not always cleaned up.

1. We want the files for a print job to be removed as early as possible
typically because the print job was cancelled, completed, the app
or the spooler crashed during print job construction. We were keeping
around in the spooler and hence to disc infos for jobs that are in
final state since the app that created them may hold a reference to
a local print job objec whose info it can access to get the latest
print job state potentially after the job reached final state. The
issue was that we were persisting to disc created print jobs which
were during construction which requires careful handling for the
various cases above. This is tricky and error prone.

We used to tell the spooler to forget the print jobs infos when the
app that created them died. The implementation to forget a print
job was not careful and was nuking currently running print jobs in
addition to the ones in a terminal state. Further, if the app dies
before a print job is completed we were left with a stale print
job in the spooler since we missed the signal to forget it (assuming
we forget only inactive jobs). These issues suggest that the approach
is problematic.

Now we have a cache of print job infos for the jobs an app created.
This cache is updated when the state of a print jobs changes using
the new print job state observation code. When the app dies we
remove the cached jobs for that app. Now if the app calls to get
the print jobs it gets the cached ones, i.e. the print jobs it
created during its lifetime, plus the print jobs that are still
active fetched from the spooler. Note that transient state cannot
be kept in the spooler since we unbind from it if there is no
work and it may get killed.

2. Improved the print sub-system logging code to show the cached
print job infos for apps and also dump the print job PDF file
names.

1. The print dialog was resizable and as a result when printers
come and go its size changes which looks bad. The dialog is
now trying to be maximally large limited by a max size or the
screen - whichever is smaller. This required moving from
GridLayout to several LinearLayouts since the former does not
support distribution of empty space evently between the items
in a row. Also we want all items in a column of inputs to be
of equal size (the spinners specifically).

2. Added labeledBy attribute to associate a view with another one
that serves as its label for accessibility purposes. We have
lebelFor attribute but it is not useful in most layout files
since it has to refer the auto-generated id of a view which
usually appears later in the layout file, thus generating a
compilation error. This was needed for the accessibility support
of the print dialog.

bug:10631660

2. Disabling the spinners or the print button did not produce
visual feedback leading to user frustration.

2fbd2a7f070f246ddafd9de94efa9a98861e9136 17-Sep-2013 Svetoslav <svetoslavganov@google.com> App UI freezes when printing. API clean up.

1. The UI of a printing app was freezing a little when calling the print
method since the print manager service was waiting for it to bind to the
print spooler which generated the print job id (and the initial print
job info really). Now the print manager service is responsible for job
id generation and does not not wait for the print spooler to spin. Hence,
the app UI is not blocked at all. Note that the print manager initiates
the binding to the spooler and as soon as it completes the spooler shows
the print UI which is hosted in its process. It is not possible to show
the print UI before the system is bound to the spooler since during this
binding the system passes a callback to the spooler so the latter can
talk to the system.

2. Changed the print job id to be an opaque class allowing us to vary the
way we generate print job ids in the future.

3. The queued print job state was hidden but the print job returned by the
print method of the print manager is in that state. Now now hidden.

4. We were incorrecly removing print job infos if they are completed or
cancelled. Doing that is problematic since the print job returned by
the print method allows the app to query for the job info after the
job has been say completed. Hence, an app can initiate printing and
get a print job whose state is "created" and hold onto it until after
the job is completed, now if the app asks for the print job info it
will get an info in "created" state even though the job is "completed"
since the spooler was not retaining the completed jobs. Now the spooler
removes the PDF files for the completed and cancelled print jobs but
keeps around the infos (also persisting them to disc) so it can answer
questions about them. On first boot or switch to a user we purge the
persisted print jobs in completed/cancelled state since they
are obsolete - no app can have a handle to them.

5. Removed the print method that takes a file since we have a public
PrintDocumentAdapter implementation for printing files. Once can
instantiate a PrintFileDocumentAdapter and pass it to the print
method. This class also allows overriding of the finish method to
know when the data is spooled and deleted the file if desired, etc.

6. Replaced the wrong code to slice a large list of parcelables to
use ParceledListSlice class.

1. If a print service does not export its activities for settings and
adding printers the print spooler ignores them instead of crashing.
Also if the service is not enabled its activities are now ignored.

2. Added a dedicated permission for a print service to optionally
protect its settings and add printer activities such that only the
system can bind to them.

3. Fixed a crash in the print dialog if its content is detached
from the window and animators are running.

3. Removed the APIs on PrintDocumentInfo that describe the
layout of the content as they are not needed. For example,
if the print attributes passed in layout require landscape
mode, the the app should just create a PDF page with the
wider side up and draw its content in portrait. The printer
will then rotate the page.

1. Updated the security mode of the print spooler. Now the spooler
is not signed with the system key, it is not a privileged app so if
it gets compromised (PDF rendering is a potential attack vector)
it cannot access dangerous permissions. Also only the system
can bind to the spooler.

2. Added APIs for asking a print service to start and stop tracking
a given printer. This is need for the case when the user selects
the printer and the print service should do a best effort to keep
the system updated for the current state of the printer.

3. Added APIs for putting a print job in a blocked state. A print
service would report the print job as blocked if for some reason
the printer cannot proceed, e.g. 99 pages are printed but there
is no paper for the last one. The user has to add more paper
and the print service can resume the job.

4. Changed the read/write APIs to use ParcelFileDescriptor instead
of FileDescriptor since the latter does not have a clean API for
detaching the wrapped Linux file descriptor when one wants to
push it to native.

5. Added API for getting the size of the printed document so the
print service can avoid handling big filed over cellular network
or ask the user if needed.

6. Now the print services that are preinstalled on the system image
are automatically enabled.

2. Added APIs for a print app to specify which constraints imposed

are not handled by the printer again, e.g. if the content is to
be in landscape the the app generated such content the printer
should rotate the content again.

3. Added some printer statuses.

4. Added a helper class that generates PDF documents with correct
size based on the passed in print attributes.

5. Exposed a ctor for PageRange which was hidden by mistake and apps
could not create page ranges. Added API for changing the printer
status.

1. Added support for selecting a printer from the all printers activity
that is not in the initial printer selection drop down. The user
initially sees a sub set of the printers in the drop down and the
last option is to see all printers in a separate activity. Some
of the printers in the all printers activity are not shown in the
initial drop down.

2. Refactored printer discovery by adding (private for now) printer
discovery app facing APIs. These APIs are needed to support multiple
printer selection activities (print dialog and all printers activities)
and also the settings for showing all printers for a service.

Now multiple apps can request observing for printers and there is
a centralized mediator that ensures the same printer discovery
session is used. The mediator dispatches printer discovery specific
requests to print services. It also aggregates discovered printers
and delivers them to the interested apps. The mediator minimizes
printer discovery session creation and starting and stopping discovery
by sharing the same discovery session and discovery window with
multiple apps. Lastly, the mediator takes care of print services
enabled during discovery by bringing them up to the current
discovery state (create discovery session and start discovery if
needed). The mediator also reports disappearing of the printers
of a service removed during discovery and notifies a newly
registered observers for the currnet printers if the observers are
added during an active printer discovery session.

3. Fixed bugs in the print UI and implemented some UX tweaks.

activity)

4. Refactored the printer discovery session APIs. Now one session
can have multiple window discovery windows and the session stores
the printers found during past discovery periods.

5. Merged the print spooler and the print spooler service - much
simpler and easier to maintain.

one session do not interfere with another session.

2. Updated the app facing APIs to pass in a document info along
with a printed file. Also exposed the print file adapter so
apps that create a temporary file for printing can intercept
when it is read by the system so the file can be deleted.

3. Updated the print service documentation.

1. The singleton print spooler isntance is created when the print spooler
service gets a connection to the system and is destroyed when this
connection is removed. Note that if the spooler has work, then the
connection to the system will not be removed.

When the spooler is created, it reads the stored state and notifies the
system which in turn dispatches this to the print services.

When the system connects to the spooler and passes it a connection, we
schedule a delayed check whether there is work for the spooler. We do
not handle this immediately to avoid intermitted spinning on and off
of the spooler process if a client makes a sequence of queries while
the spooler has really no work.

2. Fixed a bug in the NotificationManagerService where adding a notification
and removing it immediately after that does not remove the notification.
The code that is adding a notification is run on a handler thread while
the code to remove it on the calling thread. This creates a race and
erroneous results. Now the removal is also scheduled on the handler.

3. Many small fixes here and there.

1. Added notifications for a queued print job, for a started print job,
for ongoing canceling a print job, and for a failed print job. The
notifications for queued and started state have a cancel action. The
notification for failed print job has a cancel and a restart action.

2. Propagating failure message from the print service to the notifications.

3. PrintJobConfigActivity was not setting the initial value for the
print job copies and was not updating the UI immediately after creation.

4. Refactored PrintJobConfigActivity to avoid using the hack to avoid
reaction for item selection change in a spinner for an event that
happened before the callback was registered.

5. Removed the label attribute from PrinterInfo and now PrinterId is
composed of the printer name and the service component name. This
is nice since for restarting print jobs we do not need to store
information about the printer except the printer id which is
already part of the PrintJobInfo's data. Also the printer name
is not expected to change anyway.

6. Allowing cancellation of a queued print job. Also no print job is
cancelled without asking the managing print service to do that.
Before we were immediately canceling print jobs in queued state
but it was possible for a buggy print service to not set the
print job state to started before starting to do expensive work
that will not be canceled.

7. PrintServiceInfo was throwing an exception the the meta-data
XML for the print service was not well-formed which would crash
the system process. Now we just ignore not well-formed meta-data.

8. Removed unused permissions from the PrintSpooler's manifest.

1. Added APIs for adding partially initialized PrintInfo objects
enabling light-weight lookps for print serivces that want to
populate the list of available printers without querying each
of them for its capabilities. This includes APIs for the system
to request from a print service to update certain printers.

2. Fixed a bug in PrinterId#equals().

3. Added equals and hasCode implementaion to PrinterInfo. Also
the defaul in PrinterInfo are now an array instead of a
SparseArray - cheaper.

4. Now PrintJobConfigActivity works with partially specified
printers. Specifically, if such a printer is selected the
activity is requesting from the print service to update
the printer. We are currently not handling the timeout case.
It also handles udpated pritners.

1. API changes: Moved copies API from PrintAttributes to PrintJobInfo;
Changed the PageRange list to an array in PrintDocumentAdapter#onWrite;
Added onCancelled method to the layout and write callbacks.

2. Refactored the serialization of remote layout and write commands. Now
the commands are serialized by the code in the client instead in the spooler.
The benefit is simple code since the client has to do a serialization to delegate
to the main thread anyway. The increased IPC found is fine since these calls
are quite unfrequent.

3. Removed an unused file: IPrintSpoolerObserver.aidl

4. Added equals and hasCode implementation to PageRange, PrintAttributes,
MediaSize, Resolution, Margins, Tray, PrintDocumentInfo.

5. Added shortcut path for query APIs on PrintJob that return cached values
if the print job is in a uncuttable state, i.e. completed or cancelled. Failed
print jobs can be restarted.

6. PrintJobInfo was not properly serialized.

7. Updated the look of the print dialog to be stable if there is and there isn't
currently selected printer.

8. PrintJobCOnfigActivity now calls onLayout on every print attributes change
but requests a write only on print preview or print button press. Also if the
layout did not change the content and it is already written no subsequent
call is made. Also if the selected pages change and we already have them
no subsequent call to write is made. Also the app is called with print preview
attribute set when performing layout and with it cleared after the print button
is pressed. A lot of changes making sure that only valid actions are enabled
in the activity (looks like a dialog) at a given time frame. The print job config
activity is also hidden after we got all the data, i.e. layout and write are done.

9. The callback from the print spooler to the system are scheduled via messages
to avoid lock being held during the call. It was hard to guarantee that since a
method holding a lock may be calling one that would like to release the lock
at some point to make the callbacks.

10. Print spooler state is persisted only if something changes in a completed
print job, i.e. not one that is being constructed due the print job config dialog.

11. Fixed a potential race in the RemotePrintSpooler where it was possible that
a client that got a handle to the remote spooler calls into an unbound spooler.
E.g: the client gets the remote interface with a lock held, now the client releases
the lock to avoid IPC with a lock, during the IPC scheduling the spooler has
notified the system that it is done and the system unbinds from it, now the
client's IPC is made to a spooler that is disconnected.

0d1daa50f6d180c57f92596501e2e5c0b5ef9997 23-Jul-2013 Svetoslav Ganov <svetoslavganov@google.com> Updating the print dialog and its interactinos with the printing app.

1. Added support for reporting the old print attributes during layout.
Now we keep track of the old print attributes, so the app can
compute the delta and decide whether re-layout work is needed.

2. Fixed PrintDocumentAdapter callback interleavings. Layout callbacks
were intermixing with write ones - a mess. Now we make an attempt
to cancel layout and write if they respond to cancellation, otherwise
we wait but do not interleave them.

3. Refactored the PrintJobConfigActivity for easier maintenance and
to have a single update UI method that does the minimal amount
of work.

88d199130d44c6bacb383a7757e782cf97483c68 22-Jul-2013 Svetoslav Ganov <svetoslavganov@google.com> Implement persistence/restoring of print spooler state.

1. Implemented the persistence and restoring of the print spooler state.
The print spooler state is saved as an XML on every print job change
and is restored when we bind to the spooler. The system does not
unbind from the spooler until the state persistence completes. We
are now storing the entire state, i.e. all print jobs, when a single
one changes. This is not optimal but we are not expecting to have
many such at the same time, so for now we err for simplicity of
implementation.

2. Enforcing a non-empty print job name.

3. Hidden the STATE_CREATED print job state which should never be visible to a
client since this is the state of a print job during construction, i.e. the
print dialog is up and we are doing back and forth with the app.

4. Fixed some PrintAttributes APIs that were incorrectly taking in a PackageManager
instance.

5. Updated the PrintSpooler build file due to splitting the framework into multiple
jars.

1. Adding bundle with metadata to PrintDocumentAdapter#onLayout
with one key for now to specify whether this is for a preview.

2. Cleaned up docs.

1. Fixed a case in which the onPrintCompleted callback may not be invoked.

2. Added string resulrces for the different error messages for failed
printing in OnPrintCompletedCallback

3. Fixed the string comments for the MediaSize constants.

4. Added APIs to create certain print attributes by passing in a
string label instead of resource and package name since in some cases
a print service may be getting already internationalized lables
or it may not know all possible values.

5. Fixed a crash in PrintJobConfigActivity if there is no input or
output tray.

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.
