Summary:
frameworks/base
- fix profiling to collect data beyond the first snapshot
- avoid many small files, accumulate data over process lifetime
libcore:
- add support for VM specific sampling, trying to cut down overhead
- added support for converting snapshot files to text format
- fixed race in profiler when stopping
dalvik
- added VMStack.setThreadStackTrace interface for filling a stack
trace into an existing StackTraceElement[]
Details:
frameworks/base
Changed snapshots from text to binary hprof format (bumping version to 3)
Changed from one file per snapshot to one file per process lifetime.
Restart profiling after snapshot.
core/java/com/android/internal/os/SamplingProfilerIntegration.java
Add quick test in maybeSnapshot to avoid doing work when the
SamplingProfilerIntegration is disabled. Make maybeSnapshot
private. Remove unneeded memory allocation in handleLowMemory.
core/java/android/app/ActivityThread.java
libcore
Added ThreadSampler interface. This allows VM specific thread
sampling optimizations. The portable version continues to use
Thread.getStackTrace().

dalvik/src/main/java/dalvik/system/profiler/PortableThreadSampler.java

Add VMStack.setThreadStackTrace and use in new DalvikThreadSampler
to avoid allocating a full stack trace when only a limited depth
is desired.

dalvik/src/main/java/dalvik/system/VMStack.java
Refactored BinaryHprof.readMagic out of BinaryHprofReader so it
can be used by HprofBinaryToAscii converter to probing file
types. Added magic number constant to be shared between readMagic
and BinaryHprofWriter.

dalvik/src/main/java/dalvik/system/profiler/BinaryHprofWriter.java
dalvik/src/main/java/dalvik/system/profiler/HprofBinaryToAscii.java
Removed unneeded HprofWriter interface. Changed to simpler static
interface to write HprofData to binary and text formats.

dalvik/src/main/java/dalvik/system/profiler/AsciiHprofWriter.java
dalvik/src/main/java/dalvik/system/profiler/BinaryHprofWriter.java
dalvik/src/test/java/dalvik/system/profiler/SamplingProfilerTest.java
Added support for reading snapshot files created by
SamplingProfilerIntegration by stripping the text header to allow
easier conversion to the text format.
dalvik/src/main/java/dalvik/system/profiler/HprofBinaryToAscii.java
Fixed race between Sampler and
SamplingProfiler.stop. SamplingProfiler.stop previously simply
called the Sampler's TimerTask.cancel method, but this does not
wait for a currently running Sampler to finish. The TimerTask
documentation says the only reliable way to do this is to have the
run() cancel itself, so that is what is now done, with new code to
ensure that SamplingProfiler.stop does not return until the
Sampler has been terminated.

dalvik
Refactored VMStack_getThreadStackTrace to create helper getTraceBuf
used to implement new VMStack_setThreadStackTrace. The new version
interface fills an existing StackTraceElement[], avoid allocating
unnecessary StackTraceElements.
vm/native/dalvik_system_VMStack.c
Refactor dvmGetStackTraceRaw to create dvmSetStackTraceRaw which
fills in an existing, potentially smaller, StackTraceElement[].
vm/Exception.c
vm/Exception.h
Change stack depths to be unsigned to avoid signed/unsigned comparison warnings.

The input dispatcher sends a HOVER_ENTER to a window before dispatching
it any HOVER_MOVE events. For compatibility reasons, the window will
*also* receive the HOVER_MOVE. When the pointer moves into a different
window or the pointer goes down or when events are canceled for some reason,
the input dispatcher sends a HOVER_EXIT to the previously hovered window.
The view hierarchy behavior is similar. All views under the pointer
receive onHoverEvent with HOVER_ENTER followed by any number of HOVER_MOVE
events. When the pointer leaves a view, the view receives HOVER_EXIT.
Similarly, if a parent view decides to capture hover by returning true
from onHoverEvent, the hovered descendants will receive HOVER_EXIT.
The default behavior of onHoverEvent is to update the view's hovered
state by calling setHovered(true/false). Views can query their current
hovered state using isHovered().
For testing purposes, the hovered state is mapped to the pressed
drawable state. This will change in a subsequent commit with the
introduction of a new hovered drawable state.

Hide the action bar upon finishing a mode if it was hidden when the

will not hide when the mode finishes.

- CorrectionSpan is a span which has suggestions made by IME.
This has a function to change the current IME to other IME specified
in this span. For security reasons, only the current IME
is allowed to use this function through InputConnection.
(IME token is used for checking the validity of it.).
- CorrectionSpan stores following information:
flags, subtype Id, InputMethodInfo Id, suggests, locale, original string

This is used when there is only one application available and the user has
not chosen to start it by default.
If more than one application is available we continue to use UsbResolverActivity

* commit '529eb76b8add903c67ecf0178b6b4603edd64ebb':
Fix bug 4065021 - Adjust spacing of the "home" action bar item to be consistent with the "up" indicator
consistent with the "up" indicator
Make sure that the "home" affordance in the action bar always occupies
the same amount of space regardless of whether or not the "up"
indicator is visible. This means centering the application icon/logo
in the remaining space after the "up" indicator has been added.

When a USB device or accessory is connected, the UsbService now asks the
user which application to associate with the device or accessory.
Applications interested in devices or accessories must specify the
devices they work with via meta-data attached to their manifest.
Permission to communicate with the device is assigned when the user chooses
the activity to use for the device.
The user has the option of clicking the "always use this application" checkbox
to make the assignment automatic in the future.
The user may later clear this preference and revoke permission for an application
to have permission to communicate with the device by clicking the "Clear defaults"
button for the activity in the Manage Applications panel in Settings.
Added class UsbResolveActivity (a subclass or ResolveActivity for choosing
an activity for a USB device or accessory)
Added UsbDeviceManager, which manages the mapping between USB devices/accessories
and applications, including default applications for devices and accessories,
and manages application permissions.
Add interface to allow Settings to clear device and accessory
preferences and permissions for an application.
Remove obsolete ACCESS_USB permission.
Add new signatureOrSystem MANAGE_USB permission to allow administrating
preferences and permissions.
Moved UsbService.java to a "usb" subdirectory, along with new classes
UsbResolveActivity and UsbDeviceManager.

Dispatch ACTION_HOVER_MOVE and ACTION_SCROLL through the View
hierarchy as onGenericTouchEvent. Pointer events dispatched
this way are delivered to the view under the pointer. Non-pointer
events continue to be delivered to the focused view.
Added scroll wheel support to AbsListView, ScrollView,
HorizontalScrollView and WebView. Shift+VSCROLL is translated
to HSCROLL as appropriate.
Added logging of new pointer events in PointerLocationView.
Fixed a problem in EventHub when a USB device is removed that
resulted in a long stream of ENODEV errors being logged until INotify
noticed the device was gone.
Note that the new events are not supported by wallpapers at this time
because the wallpaper engine only delivers touch events.
Make all mouse buttons behave identically. (Effectively we only
support one button.)
Change-Id: I9ab445ffb63c813fcb07db6693987b02475f3756
Added support for tracking the mouse position even when the mouse button
is not pressed. To avoid confusing existing applications, mouse movements
are reported using the new ACTION_HOVER_MOVE action when the mouse button
is not pressed.
Added some more plumbing for the scroll wheel axes. The values are
reported to Views but they are not yet handled by the framework.
Change-Id: I1706be850d25cf34e5adf880bbed5cc3265cf4b1
Added API on InputDevice to query the set of axes available.
Added API on KeyEvent and MotionEvent to convert keycodes and axes
to symbolic name strings for diagnostic purposes.
Added API on KeyEvent to query if a given key code is a gamepad button.
Added a new "axis" element to key layout files to specify the
mapping between raw absolute axis values and motion axis ids.
Expanded the axis bitfield to 64bits to allow for future growth.
Modified the Makefile for keyboard prebuilts to run the keymap
validation tool during the build.
Added layouts for two game controllers.
Added default actions for game pad button keys.
Added more tests.
Fixed a bunch of bugs.
