- Support unbounded ranges, e.g. 4- == 4-pageCount and -2 == 1-2
- Do not allow reverse ranges, i.e. 7-3 is not allowed anymore
- restrict characters that can be typed into field
- force numeric keyboard
- Fix bug that we update the selected pages even if the page ranges are
invalid

scrap
documentInfo.PageCount might be set to "unknown" == -1. Hence we don't
know where the last page to scrap ends. Hence defer this decision all
way until PdfManipulationService.removePages as then we know the actual
pages of the document.

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.

Also: Always destroy print spooler provider when it was initialized to
avoid service leakage if print activity was finished after
onCreate but before onPrinterRegistryReady.

In PrintActivity.OnPause we set the print job state based on the
PrintActivity state. The issue was that FINISHED was interpreted as
"cancel print job". Actually with FINISHED does not tell what state the
job should be in.
The only purpose of the finished state was to guard against
double-invocation of doFinish().
Hence remove this recently introduced state and use a simple boolean to
guard against doule invocation of doFinish().

of pages.
If the printing app declares more pages than the print preview pdf has
we used to throw an exception in the PDFManupulationService. This caused
the bitmap to be never written and the read-bitmap function to hang
forever. This was because read() return 0 meaning "pipe is closed" which
lead to an infinite loop. Now a read of 0 page might cause an exception
if the page is not fully read. This exception then causes the
preview_page_error to be displayed.

are canceling the command.
Before it could happen that we have a pending cancel on a layout command
but the layout command finishes normally. This enqueued a new write
command before the PrintActivity is notified. This in turn prevented the
printactivity from finishing as the write command was still pending.

This fixes two bugs
(1)
1. Printer was unknown when "all printer" activity was opened
2. Printer gets selected in "all printers" activity
3. Printer is unknown at the time the activity returns and thereby does
not get selected
(2)
If a print service gets disabled _all_ printers of the print service
will be marked as "removed" but do not removed from the adapter. This
is superflous as none of them can be selected anymore. The only thing
we want to make sure of is that the currently selected printer does
not get removed.
The workflow is now always:
- set mCurrentPrinter if needed
- Adjust mPrinterHolders
- adapter.notifyDataSetChanged()
-> PrintersObserver.onChanged()
-> onItemSelected

It can happen that before we stopped we reported a set of printers. Then
while the loader is stopped, we lost all printers. Then on re-start we
need to tell the clients that there are no printers anymore.
There is one issue: The fused-printers-provider might be started
before the printer registry is fully created. In this case we get a callback
and get all king of NPEs. Hence enqueue the first load behind the
current thread. This makes sure that the current operation - creation of
the printer registry - is finished.

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.

When switching between two printers with different margins but with the
same paper size we were missing updates of the print preview. This
change triggers these updates.
The issue was the we reuse the a bitmap when a page is rewritten. This
causes View.setBackground(drawable) to do nothing as the old
background is the same as the new one. This function only checks the
background drawable object reference, not the content. Hence we need to
add a call that notifies the listeners to the changes on the content of
the drawable.

Bonus: Remove Printer-onChange listener before other state gets cleaned
up. Otherwise onChange callbacks at the wrong time cause into
destroyed data.
