There were a couple problems with work profile state in location. First,
we assumed that notifications sent to parent users would also be sent to
profiles but this is not true. Second we had assumed location status in
profiles was always identical to the parent user, but work profiles may
have user restrictions applied which are not present on the parent user.
The easiest way to handle these issues seems to be to expand LMS user
handling to deal with all users, rather than making various assumptions
which may or may not be true.
This also means we need to store last locations on a per profile basis.
Since we're refactoring how last location works completely, we also
removed the special NO_GPS handling for last locations. With the new
permission strings we now no longer have to exclude gnss based location
from coarsening. This lets us:
1) deprecate and remove various constants and methods use for storing
coarse locations tied to fine locations
2) substantially simplify code that calculated coarse location
This also exposed numerous bugs in the location service where we were
using the current user's state instead of the calling user's state,
which could have exposed the current user's location to other users
inappropriately.

DPM can currently control the master location toggle, but cannot
influence the behavior of individual providers. This adds an API for
DPM (or other privileged entities) to request a provider to turn itself
on.
Practically, this is necessary to allow DPM to control network location,
which may be gated by additional consents. This change also renames some
internal location code to make clearer the distinction between provider
enabled and provider allowed: enabled = location on && allowed

Fix some minor bugs and ensure fused location provider correctly
supports location bypass. This is especially important for when
location bypass is invoked in direct boot.
The added UPDATE_DEVICE_STATS permission is necessary for FusedLocation
to correctly update WorkSources. FusedLocation receives work from LMS and
then further delegates that work to other location providers. The other
location providers should be informed of the correct applications for
battery blame, and should not be blaming the FusedLocation package.
1) This is the minimally scoped permission necessary to battery blame
correctly.
2) There is no way to attribute battery blame without this permission.
3) This is the correct permission - as required by LocationManager, and
this permission will likely never be removed (FusedLocation will always
need to battery blame).

This will replace the LocationManager.getNetworkProviderPackage() API
with LocationManager.isProviderPackage(). The network provider should
not be considered special.
In addition, providers now have the ability to specify additional
packages that may make location requests on their behalf, so that those
packages can be considered location providers as well.

com.android.location.provider.stubs is the stubs library for the shared
library com.android.location.provider. The stubs library is intended to
provide the stable set of APIs to the apps implementing location
provider.
Without the stubs library, apps had to directly link to the shared
library which is built without Android SDK and exposes private APIs that
are not intended to be used by apps. This also has been causing the
lin-type check warnings when the shared lib is used by apps built with
SDK; apps built with SDK is not allowed to link to lib built without
SDK. This has been reported as warnings but will soon be errors. Now
such apps are required to link to the stubs lib, which is built with
SDK.
While building the stubs library, following APIs are made hidden because
they are exposing private APIs from the Android platform.
1) Activity* classes are removed from the API, as they are not intended
to be used by apps since O.
2) GeocodeProvider and GeofenceProvider are removed from the API.
3) LocationProvider.mLocationManager is removed as it is exposing the
private symbol ILocationProvider
4) ProviderPropertiesUnbundle.getProviderProperties are removed from the
API as it is exposing the private symbol ProviderProperties.
5) The constructor of ProviderRequestUnbundled is removed since the
class is intended to be instantiated by the service.

Let HAL implementation tell if geofencing/batching is
supported and which technologies (GNNS, wifi, etc)
can be used.
Still todo: Add ability for GmsCore geofencing to
tell which technologies are supported (instead of
just using it to update monitoring). This requires
SystemApi change + approval so will do in separate CL.
Note that the classes in the lib are not copied
directly into GmsCore. The instance will always
be whatever is in the platform. This is why
the callback is backwards compatible as long as
their is a default implementation (but not if
it's abstract).

One problem this turned up is, because FastPrintWriter does
its own buffering, a lot of code that used to use PrintWriter
would fail -- if it pointed to a StringWriter, there was no
buffering, so it could just immediately get the result. Now
you need to first flush the FastPrintWriter.
Also added some new constructors to specify the size of buffer
that FastPrintWriter should use.

Themes: Fused Location, Geofencing, LocationRequest.
API changes
o Fused location is always returned when asking for location by Criteria.
o Fused location is never returned as a LocationProvider object, nor returned
as a provider String. This wouldn't make sense because the current API
design assumes that LocationProvider's have fixed properties (accuracy, power
etc).
o The fused location engine will tune itself based on the criteria passed
by applications.
o Deprecate LocationProvider. Apps should use fused location (via Criteria
class), instead of enumerating through LocationProvider objects. It is
also over-engineered: designed for a world with a plethora of location
providers that never materialized.
o The Criteria class is also over-engineered, with many methods that aren't
currently used, but for now we won't deprecate them since they may have
value in the future. It is now used to tune the fused location engine.
o Deprecate getBestProvider() and getProvider().
o Add getLastKnownLocation(Criteria), so we can return last known
fused locations.
o Apps with only ACCESS_COARSE_LOCATION _can_ now use the GPS, but the location
they receive will be fudged to a 1km radius. They can also use NETWORK
and fused locatoins, which are fudged in the same way if necessary.
o Totally deprecate Criteria, in favor of LocationRequest.
Criteria was designed to map QOS to a location provider. What we
really need is to map QOS to _locations_.
The death knell was the conflicting ACCURACY_ constants on
Criteria, with values 1, 2, 3, 1, 2. Yes not a typo.
o Totally deprecate LocationProvider.
o Deprecate test/mock provider support. They require a named provider,
which is a concept we are moving away from. We do not yet have a
replacement, but I think its ok to deprecate since you also
need to have 'allow mock locations' checked in developer settings.
They will continue to work.
o Deprecate event codes associated with provider status. The fused
provider is _always_ available.
o Introduce Geofence data object to provide an easier path fowards
for polygons etc.
Implementation changes
o Fused implementation: incoming (GPS and NLP) location fixes are given
a weight, that exponentially decays with respect to age and accuracy.
The half-life of age is ~60 seconds, and the half-life of accuracy is
~20 meters. The fixes are weighted and combined to output a fused
location.
o Move Fused Location impl into
frameworks/base/packages/FusedLocation
o Refactor Fused Location behind the IProvider AIDL interface. This allow us
to distribute newer versions of Fused Location in a new APK, at run-time.
o Introduce ServiceWatcher.java, to refactor code used for run-time upgrades of
Fused Location, and the NLP.
o Fused Location is by default run in the system server (but can be moved to
any process or pacakge, even at run-time).
o Plumb the Criteria requirements through to the Fused Location provider via
ILocation.sendExtraCommand(). I re-used this interface to avoid modifying the
ILocation interface, which would have broken run-time upgradability of the
NLP.
o Switch the geofence manager to using fused location.
o Clean up 'adb shell dumpsys location' output.
o Introduce config_locationProviderPackageNames and
config_overlay_locationProviderPackageNames to configure the default
and overlay package names for Geocoder, NLP and FLP.
o Lots of misc cleanup.
o Improve location fudging. Apply random vector then quantize.
o Hide internal POJO's from clients of com.android.location.provider.jar
(NLP and FLP). Introduce wrappers ProviderRequestUnbundled and
ProviderPropertiesUnbundled.
o Introduce ProviderProperties to collapse all the provider accuracy/
bearing/altitude/power plumbing (that is deprecated anyway).
o DELETE lots of code: DummyLocationProvider,
o Rename the (internal) LocationProvider to LocationProviderBase.
o Plumb pid, uid and packageName throughout
LocationManagerService#Receiver to support future features.
