The right way to expose this API is done via MediaBrowser.
Bug: b/28791287
Change-Id: I0a8a185934fd7aaa9f2b5eac7398955fa380060f
(cherry picked from commit b5fbb75aa26a6322b26b1289cc5d14a8c31acb34)
The public API for getting at KeyphraseSoundModels is based on the user,
locale, and keyphrase ID. However, the sound model database would allow
multiple models to be registered using the same values, as it has a
primary key on the model UUID. This can potentially lead to a scenario
where multiple models are enrolled for the same user, and the data that
is returned when querying models is arbitrary.
V6 of the sound model database now enforces a primary key over the user
ID, locale and keyphrase ID. When inserting a new model with the same
primary key, the old model will be removed and the new model will be
used instead.
When upgrading from V5 to V6, if there are any models that would violate
the primary key constraint, they are all dropped.

Currently, if the "ro.boot.vendor.overlay.subdir" property is set, we
only search in the subdir. It seems more powerful to search both in
there and in the standard /vendor/overlay directory.
Also, RRO packages have the "priority" attribute in the <overlay>
attribute in AndroidManifest.xml which serves for disambiguation.

preferred_time_zones.xml is not referenced in any code and has been
deleted here.
TimeUtilsTest.java is broken / out of date and semi-duplicates code
in android.util.cts.TimeUtilsTest. It has been deleted here.
time_zones_by_country.xml file has not been updated since (at least)
2009.
Ideally this information would be updated as needed when the
timezone rule data is updated on device. This change just brings the
data up to date without addressing that issue. Given the apparent,
non-obvious, ordering requirements it may not be possible to use
zone1970.tab data directly.
---------------
Impact assessment:
At the time of writing time_zones_by_country.xml is used from:
Non-public methods:
android.util.TimeUtils.getTimeZones(String)
Public methods:
android.util.TimeUtils.getTimeZone(int, boolean, long, String)
android.util.TimeUtils.getTimeZonesWithUniqueOffsets(String)
Therefore there is some app / user benefit from updating it.
Within the framework, this affects:
telephony.ServiceStateTracker - in some circumstances when receiving
offset information from cell networks when better information is not
available.
There is some clockwork code affected that uses the calls for similar
purposes.
---------------
Notes on file formats / mapping the IANA source data:
The updated data was sourced from the IANA tzdata 2016g file
called zone1970.tab. The time_zones_by_country.xml file was manually
edited in a text editor using criteria detailed below.
The zone1970.tab file maps country codes (column 1) to a zone ID
(column 3). A country can be mapped to multiple zones. The zone.tab file
that was likely used in the past is similar in content and format. See
the zone.tab file header for details of the differences.
The time_zones_by_country.xml can have multiple entries for each
country, starting with a comment.
Comments exist for each (Country, Offset) pair. The name is
free-text, the offset is a non-DST offset for a zone as of 14th Oct
2016 using the 2016g data.
<!-- {Country name}, {offset from UTC} -->
Countries are listed in ASCII ascending order of the country code.
Within each country offsets are mostly ordered east to
west. An exception appears to be Australia. The data may have a
secondary order of "best match" (e.g. maybe by population). This might
be important for getTimeZone(int, boolean, long, String)) since it
returns the first match for a given offset, dst, country.
The timezone offset, transition information itself (offset, dst) is
pulled from the timezone rules data on the device, not this file.
The data is encoded for each (Country, Offset) pair by a sequence
of:
<timezone code="xx">{Olson ID}</timezone>
xx is the country code from column 1 in the zone1970.tab file, the
element content is the zone ID from column 3.
---------------
Notes on the changes made to time_zones_by_country.xml:
There are various changes in this commit associated with switching from
zone.tab to zone1970.tab as a data source: zone.tab uses different
Olson IDs due to the different criteria used by these files.
The offset in each case will be the same so will have no practical
effect on offsets / zone detection, though will affect the exemplar
location for the zone found.
The remaining changes reflect actual zone / offset changes that
have occurred.
When adding new zones or rearranging existing ones they have been
positioned so as not to modify the first zone for each country or
the first zone per offset because of the uncertainty about the
secondary ordering. This is to avoid the risk of now picking a
different zone for a country or {country + dst + offset}. This
has resulted in a couple of places where the ordering is
non-intuitive.
The zone names and the offset information contained in the comments was
checked semi-manually using other 2016g data, i.e. the base offset of
each zone was checked against output from a script that created a
TimeZone object from each Olson ID in the file and output the raw
(non-DST) offset.
