Half floats (often called fp16) are commonly used to store floating
point data efficiently without having to use lossy compression schemes.
Half floats are commonly used in the following cases:
- Wide gamut colors
- Meshes (OpenGL and Vulkan)
- HDR images/textures
- Lookup tables as textures (OpenGL and Vulkan), particularly
in physically-based renderers
- Maching learning/compute
OpenGL and Renderscript both provide Java language APIs that accept
half floats but the platform offers no support to create fp16 values
from fp32 data. The Half class is an IEEE 754 compliant implementation
of half floats that can be used to feed OpenGL and Renderscript properly
encoded values. A comprehensive series of test is also added to CTS.
Test: cts-tradefed run singleCommand cts-dev --module CtsUtilTestCases --test android.util.cts.HalfTest

Factor in the timestamp when computing the Tx/Rx rates. The
reported rate is a combination of current and previous rates
with a heavier weight from the current rate.
Bug: 30982272
Test: Ran the new image and compared the results against the
old algorithm.

It was a bit weird to have them in WindowToken, so we create
WallpaperToken where they have a better home.
Test: Device still boots, wallpaper scrolling still
works.

This CL provides the initial, skeleton implementation of the Auto-Fill
Framework classes:
- Defines the system service and app-based
AIDL (IAutoFillManagerService.aidl and IAutoFillService.aidl respectively).
- Defines the 'adb shell cmd' interface.
- Defines the permission required to access the service.
- Registers the service on SystemServer.
- Adds the code to bind the app-specified service to system_server.
- Defines the service class (AutoFillService) required by providers.
- Implements the initial startSession() method.
This is still a very early, "work-in-progress" change:
- It has many TODOs.
- It does not have unit or CTS tests yet.
- It does not provide a callback method to auto-fill the fields.
- In fact, it has a lot of TODOs.
Despite these adversities, it can be tested by following the steps
below:
1.Create an app with a service extending AutoFillService
2.Implement the onNewSession() method
3.In the manifest:
- Listen to android.service.autofill.AutoFillService intents.
- Require the android.permission.BIND_AUTO_FILL permission.
4.Explicitly set the app as an autofill-service by running:
adb shell settings put secure auto_fill_service MY_APP/.MY_SERVICE
5.Start a session against the top activity:
adb shell cmd autofill start session

This is the first swack at the new, 2-phase API. Adds the new methods
to the resolver service and makes the split name explicit on the
installer intent.
The 2nd phase will not yet be invoked; that's coming in a follow-on
change.
Bug: 25119046
Test: build & install the sample resolver and run 'adb shell am start -a android.intent.action.VIEW -c android.intent.category.BROWSABLE -d "https://www.tripadvisor.com/Tourism-g33020-San_Jose_California-Vacations.html"'

When the focus jumps from action bar to
outside of it, action bar disables focusing
on it so that tabbing couldn’t get back to it.
Currently, it does the check that the focus
has left the bar from onFocusChange(), when
the internal data structures are in process
of updating the current focus; as a result, the
check may report a wrong result, and the
focus will be blocked while it’s actually is still in
the action bar. This caused the action bar to
lose focus.
The fix makes the check in a posted action,
fixing the issue.
Bug: 32087180
Test: Manual test that the issue doesn’t repro.

To do this, I had to fix the PROCESS_STATE_NONEXISTENT constant
to be the last value (instead of the special magical -1 value)
so it semantically matches the public importance constants. I
think this is better anyway.
Also this fixes a big problem in the implementation, where we
weren't keeping track of the last proc state per uid...! Duh.
Test: manually ran testUidImportanceListener
