When Wi-fi connects at L2 layer, the beacons reach and the device
can maintain a connection to the access point, but the application
connectivity can be flaky (due to bigger packet size exchange).
We now use Watchdog to monitor the quality of the last hop on
Wi-Fi using signal strength and ARP connectivity as indicators
to decide if the link is good enough to switch to Wi-Fi as the uplink.
ARP pings are useful for link validation but can still get through
when the application traffic fails to go through and thus not best indicator
real packet loss since they are tiny packets (28 bytes) and have
much low chance of packet corruption than the regular data
packets.
Signal strength and ARP used together ends up working well in tests.
The goal is to switch to Wi-Fi after validating ARP transfer
and RSSI and then switching out of Wi-Fi when we hit a low
signal strength threshold and waiting until the signal strength
improves and validating ARP transfer.

Refactor SMS Cell Broadcast support to enable receiving CMAS warning
notifications over CDMA. The CellBroadcastReceiver app must also be
updated with the corresponding change. All cell broadcasts are now
delivered as a Parcelable SmsCbMessage object in the "message" extra
of the SMS_CB_RECEIVED_ACTION or SMS_EMERGENCY_CB_RECEIVED_ACTION,
instead of as a GSM/UMTS "pdu" byte array.
Existing functionality for ETWS and CMAS alerts over GSM/UMTS continues
to be supported using the new radio-technology independent SmsCbMessage
and related objects. Test cases are added to verify that valid and
invalid broadcast data is handled appropriately.
Unit testing discovered a bug in the BitwiseOutputStream utility class
used by the added test cases. When the BitwiseOutputStream object must be
expanded (in the private possExpand() method), the mEnd field is not
updated to the new array size. This causes a new array to be allocated
on every new write, and for all data beyond the original array allocation
to be replaced with zeroes. Fixed by adding a line to possExpand() to
update mEnd. Added a test case to BitwiseStreamsTest to verify the fix.
Besides the test cases, BitwiseOutputStream is only used by BearerData in
two places, both of which allocate a sufficient initial buffer. So the
bug in BitwiseOutputStream is not critical to fix for normal operation,
but should be fixed so that the test cases using it function correctly.

This new setting allows users to set a scale factor for the
duration and startDelay of all Animator-based animations. This
setting is very similar to the Transition animation scale and
Window animation scale settings, except this one applies specifically
to Animator animations. The property is only accessible by users
through the Settings UI, not programmatically. The value applies
system-wide and is picked up per-process at the time of the first
ValueAnimator construction.
This is an update to a previous CL; this approach uses the WindowManager
to store the animator scale settings, instead of SystemProperties.

Added new API to enable cancelation of SQLite and content provider
queries by means of a CancelationSignal object. The application
creates a CancelationSignal object and passes it as an argument
to the query. The cancelation signal can then be used to cancel
the query while it is executing.
If the cancelation signal is raised before the query is executed,
then it is immediately terminated.

Split existing network stats into two separate classes: a recorder
which generates historical data based on periodic counter snapshots,
and a collection of historical data with persistance logic.
Recorder keeps a pending history in memory until outstanding data
crosses a specific threshold. Persisting is handled through a given
FileRotator. This pattern significantly reduces disk churn and
memory overhead. Separate UID data from UID tag data, enabling a
shorter rotation cycle. Migrate existing stats into new structure.
Remove "xt" stats until iptables hooks are ready. Avoid consuming
Entry values when recording into NetworkStatsHistory. Assign
operation counts to default route interface.
Introduce "Rewriter" interface in FileRotator with methods to enable
rewriteAll(). Introduce IndentingPrintWriter to handle indenting in
dump() methods.

Adds the new interface to the user dictionary, which includes
a clean way of inserting words in any locale and support for
shortcuts.
Change Ib318c047 implements the provider part of this.

The URl from which to inject a screen-reader for WebView accessiblity support should be
configurable because: 1) The accessibility engineering team should be able to point
devices to a staging build of the screen-reader; 2) We would like to be able to change
this URL via the Google services mechanism.

By default we do not speak passwords if the user has no headset. However,
many users find this too restrictive and would like a way to enable
password announcement. While we cannot speak the passwords all the time
,to avoid leaking them, we expose a preference so each user can choose
the option that best works for him/her.

Improved quick launch bookmarks to support category-based shortcuts
instead of hardcoding package and class names for all apps.
Added a set of Intent categories for typical applications on the
platform.
Added support for some of the HID application launch usages to
reduce reliance on quick launch for special purpose keys. Some
keyboard vendors have hardcoded launch keys that synthesize
"Search + X" type key combos. The goal is to encourage them
to stop doing this by implementing more of HID.

We've decided not to disable messaging notifications with a secure setting.
Instead, all the work will be done within the messaging app itself.
