DragEvent.getResult() returns 'true' if the drop was ultimately accepted;
false otherwise. The validity of this datum is only guaranteed when the
DragEvent's action verb is ACTION_DRAG_ENDED.
Also fixes the drag-start timeout handling (though the offending app is
not yet officially declared ANR).
Implements bug 3097807

Parser is optional in obtainStyledAttributes.
A View initiates a drag-and-drop operation (hereafter just called a "drag")
by calling its startDrag(ClipData) method. Within the processing of that
call, two callbacks are made into the originating View. The first is to
onMeasureDragThumbnail(). Similarly to the core onMeasure() method, this
callback must respond by calling setDragThumbnailDimension(width, height) to
declare the size of the drag thumbnail image that should be used. Following
this, the View's onDrawDragThumbnail(canvas) method will be invoked to
actually produce the bits of the thumbnail image.
If all goes well, startDrag() will return 'true', and the drag is off and
running. (The other arguments to startDrag() provide reconciliation between
the current finger position and where the thumbnail should be placed on
the screen relative to it.)
Potential receipients of the ClipData behind the drag are notified by a
new dispatch mechanism, roughly parallel to motion event dispatch. The core
routine is the View's onDragEvent(event) callback, with the mechanics of
dispatch itself being routed through dispatchDragEvent(event) -- as in
the case of motion events, the dispatch logic is in ViewGroup, with leaf
View objects not needing to consider the dispatch flow.
Several different event 'actions' are delivered through this dispatch
mechanism:
ACTION_DRAG_STARTED: this event is propagated to every View in every window
(including windows created during the course of a drag). It serves as a
global notification that a drag has started with a payload whose matching
ClipDescription is supplied with the event. A View that is prepared to
consume the data described in this event should return 'true' from their
onDragEvent() method, and ideally will also make some visible on-screen
indication that they are a potential target of the drop.
ACTION_DRAG_ENTERED: this event is sent once when the drag point
enters the View's bounds. It is an opportunity for the View to set up
feedback that they are the one who will see the drop if the finger goes
up now.
ACTION_DRAG_LOCATION: when the drag point is over a given View, that
View will receive a stream of DRAG_LOCATION events, providing an
opportunity for the View to show visual feedback tied to the drag point.
ACTION_DRAG_EXITED: like DRAG_ENTERED, but called when the drag point
leaves the View's bounds. The View should undo any visuals meant to
emphasize their being the hovered-over target.
ACTION_DROP: when the drag ends at a given point, the View under that
point is sent this event, with the full ClipData of the payload.
ACTION_DRAG_ENDED: paralleling the DRAG_STARTED action, this is the global
broadcast that the drag has ended and all Views should return to their
normal visual state. This happens after the DROP event.

- Some new parameters are added to CreateInfo with the list of methods
or classes to override with delegates.
- DelegateClassAdapter and DelegateMethodAdapter do the work... see javadoc.

I can't find the bug number for this, but it is needed for some things
we are doing where the app building an intent may not have access to the
URI in the data field. This is for HC, but doing in GB to avoid introducing
integration issues.

- Change semantics if IDs associated with these fragments, to
work correctly when placed in a container. If the container
has an ID or you have supplied a tag, the fragment's ID is
optional.
- To do this, there is a new LayoutInflater API that allows code
creating views to access the parent container that view will
be in.
- Fix issues with state management around these fragments. Now
correctly retains state when switching to a layout that doesn't
include the fragment.
Also:
- Add new simple list layouts for items that want to show an
activated state.
- Add new Activity.dump() that can be invoked with adb shell
dumpsys; the default implementation dumps fragment state.

The makefile variable USE_OPENGL_RENDERER must be set to true to compile
libhwui and the related code in the JNI layer.
This change also removes obsolete APIs from Canvas that must not be used
and would be confusing if left in. These APIs were remnants of our first
attempt at an OpenGL renderer for the view hierarchy and had not been
taken out before Android 1.0 was released.

It would change the text rendering info but not recompute
the Java Font objects. The effect is a broken font rendering
in the EditText (which use this method to copy some Paint
object before using the copy for the actual drawing)

The old dispatch mechanism has been left in place and continues to
be used by default for now. To enable native input dispatch,
edit the ENABLE_NATIVE_DISPATCH constant in WindowManagerPolicy.
Includes part of the new input event NDK API. Some details TBD.
To wire up input dispatch, as the ViewRoot adds a window to the
window session it receives an InputChannel object as an output
argument. The InputChannel encapsulates the file descriptors for a
shared memory region and two pipe end-points. The ViewRoot then
provides the InputChannel to the InputQueue. Behind the
scenes, InputQueue simply attaches handlers to the native PollLoop object
that underlies the MessageQueue. This way MessageQueue doesn't need
to know anything about input dispatch per-se, it just exposes (in native
code) a PollLoop that other components can use to monitor file descriptor
state changes.
There can be zero or more targets for any given input event. Each
input target is specified by its input channel and some parameters
including flags, an X/Y coordinate offset, and the dispatch timeout.
An input target can request either synchronous dispatch (for foreground apps)
or asynchronous dispatch (fire-and-forget for wallpapers and "outside"
targets). Currently, finding the appropriate input targets for an event
requires a call back into the WindowManagerServer from native code.
In the future this will be refactored to avoid most of these callbacks
except as required to handle pending focus transitions.
End-to-end event dispatch mostly works!
To do: event injection, rate limiting, ANRs, testing, optimization, etc.

Well, mostly. There is still a problem here where the first time
you show the lock screen it just doesn't draw itself. I assume
this is something breaking in the view hierarchy as it floounders
around removing and adding new views as it is first being shown...
but no idea at this point what is the actual case.
