Fixed b/8276827
Vendor might want to provide their own implementation of "network
location", "fused location" and "geocoder" service. Location manager now
allows those service to be replaced by packages that have the same
signature as one of the packages in config_locationProviderPackageNames.
Such behavior might not be desirable on some devices. This change
make this behavior configurable by 3 boolean flags.
Details:
- Added three boolean flags in core/res/res/values/config.xml to enable
or disable NLP/FLP/Geocoder overlay
- Added 3 package name for the stock NLP/FLP/Geocoder. They are needed
only when overlay is disabled because LocationManagerService need to
know which package is preferred when searching for
NLP/FLP/Geocoder service.
- Made ServiceWatcher able to handle non-overlayable services.
- Fixed an NPE isue in ServiceWatcher. mPm.queryIntentServicesAsUser
might return null.
- Fixed an bug: justCheckThisPackage in bindBestPackageLocked is always
ignored.
