Add new wallpaper features for insets and offsets. Issue #17394151: WallpaperService / Engines need to get notified of WindowInsets Issue #17394203 Wallpapers need a system API to be shifted in order to support burn in protection Adds a new API on WallpaperManager to set additional offsets to make wallpapers extend beyond the display size. Insets are now reported to wallpapers, to use as they may. This includes information about the above offsets, so they can place their content within the visible area. And to help with this, also expose the stable offsets APIs in WindowInsets which is also very useful information for the wallpaper. Another new API on WallpaperManager to set a raw offset to apply to the wallpaper window, forcing it to move on the screen regardless of what the wallpaper is drawing. Fix wallpapers when used with overscan enabled, so they still extend out across the entire screen. Conveniently, the above new window insets information is very useful for this case as well! And a new wallpaper test app for all this stuff. Change-Id: I287ee36581283dd34607609fcd3170d99d120d8e

Fix backwards compatibility for introspected windows. 1. The APIs for introspecting interactive windows were reporting only the touchable windows but were missing the focused window. The user can interact with the latter by typing, hence it should always be reported. Also this was breaking backwards compatibility as if the focused window is covered by a modal one, the focused window was not reporeted and this was putting the active window in a bad state as the latter is either the focused window or the one the user is touching. 2. Window change events are too frequent as on window transition things are chanign a lot. Now we are trottling the windows changed events at the standard recurring accessibility event interval. 3. Fixed a wrong flag comparison and removed some unneded code. buy:15434666 bug:15432989 Change-Id: I825b33067e8cbf26396a4d38642bde4907b6427a

Formalize overscan metrics. The window manager now maintains and reports a new formal "overscan insets" for each window, much like the existing content and visible insets. This is used to correctly position the various UI elements in the various combination of layout options. In particular, this allows us to have an activity that is using fitSystemWindows to have the content of its UI extend out to the visible content part of the screen while still positioning its fixed UI elements inside the standard content rect (and the entire window extending all the way into the overscan area to fill the screen as desired). Okay, maybe that is not written so clearly. Well, it made my head hurt too, so suffer! The key thing is that windows now need to know about three rectangles: the overall rectangle of the window, the rectangle inside of the overscan area, and the rectangle inside of the content area. The FLAG_LAYOUT_IN_OVERSCAN option controls whether the second rectangle is pushed out to fill the entire overscan area. Also did some improvements to debug dumping in the window manager.

Screen magnification - feature - framework. This change is the initial check in of the screen magnification feature. This feature enables magnification of the screen via global gestures (assuming it has been enabled from settings) to allow a low vision user to efficiently use an Android device. Interaction model: 1. Triple tap toggles permanent screen magnification which is magnifying the area around the location of the triple tap. One can think of the location of the triple tap as the center of the magnified viewport. For example, a triple tap when not magnified would magnify the screen and leave it in a magnified state. A triple tapping when magnified would clear magnification and leave the screen in a not magnified state. 2. Triple tap and hold would magnify the screen if not magnified and enable viewport dragging mode until the finger goes up. One can think of this mode as a way to move the magnified viewport since the area around the moving finger will be magnified to fit the screen. For example, if the screen was not magnified and the user triple taps and holds the screen would magnify and the viewport will follow the user's finger. When the finger goes up the screen will clear zoom out. If the same user interaction is performed when the screen is magnified, the viewport movement will be the same but when the finger goes up the screen will stay magnified. In other words, the initial magnified state is sticky. 3. Pinching with any number of additional fingers when viewport dragging is enabled, i.e. the user triple tapped and holds, would adjust the magnification scale which will become the current default magnification scale. The next time the user magnifies the same magnification scale would be used. 4. When in a permanent magnified state the user can use two or more fingers to pan the viewport. Note that in this mode the content is panned as opposed to the viewport dragging mode in which the viewport is moved. 5. When in a permanent magnified state the user can use three or more fingers to change the magnification scale which will become the current default magnification scale. The next time the user magnifies the same magnification scale would be used. 6. The magnification scale will be persisted in settings and in the cloud. Note: Since two fingers are used to pan the content in a permanently magnified state no other two finger gestures in touch exploration or applications will work unless the uses zooms out to normal state where all gestures works as expected. This is an intentional tradeoff to allow efficient panning since in a permanently magnified state this would be the dominant action to be performed. Design: 1. The window manager exposes APIs for setting accessibility transformation which is a scale and offsets for X and Y axis. The window manager queries the window policy for which windows will not be magnified. For example, the IME windows and the navigation bar are not magnified including windows that are attached to them. 2. The accessibility features such a screen magnification and touch exploration are now impemented as a sequence of transformations on the event stream. The accessibility manager service may request each of these features or both. The behavior of the features is not changed based on the fact that another one is enabled. 3. The screen magnifier keeps a viewport of the content that is magnified which is surrounded by a glow in a magnified state. Interactions outside of the viewport are delegated directly to the application without interpretation. For example, a triple tap on the letter 'a' of the IME would type three letters instead of toggling magnified state. The viewport is updated on screen rotation and on window transitions. For example, when the IME pops up the viewport shrinks. 4. The glow around the viewport is implemented as a special type of window that does not take input focus, cannot be touched, is laid out in the screen coordiates with width and height matching these of the screen. When the magnified region changes the root view of the window draws the hightlight but the size of the window does not change - unless a rotation happens. All changes in the viewport size or showing or hiding it are animated. 5. The viewport is encapsulated in a class that knows how to show, hide, and resize the viewport - potentially animating that. This class uses the new animation framework for animations. 6. The magnification is handled by a magnification controller that keeps track of the current trnasformation to be applied to the screen content and the desired such. If these two are not the same it is responsibility of the magnification controller to reconcile them by potentially animating the transition from one to the other. 7. A dipslay content observer wathces for winodw transitions, screen rotations, and when a rectange on the screen has been reqeusted. This class is responsible for handling interesting state changes such as changing the viewport bounds on IME pop up or screen rotation, panning the content to make a requested rectangle visible on the screen, etc. 8. To implement viewport updates the window manger was updated with APIs to watch for window transitions and when a rectangle has been requested on the screen. These APIs are protected by a signature level permission. Also a parcelable and poolable window info class has been added with APIs for getting the window info given the window token. This enables getting some useful information about a window. There APIs are also signature protected. bug:6795382 Change-Id: Iec93da8bf6376beebbd4f5167ab7723dc7d9bd00

Refactor for multi-display support. Split WindowManagerImpl into two parts, the WindowManager interface implementation remains where it is but the global communications with the window manager are now handled by the WindowManagerGlobal class. This change greatly simplifies the challenge of having separate WindowManager instances for each Context. Removed WindowManagerImpl.getDefault(). This represents the bulk of this change. Most of the usages of this method were either to perform global functions (now handled by WindowManagerGlobal) or to obtain the default display (now handled by DisplayManager). Explicitly associate each new window with a display and make the Display object available to the View hierarchy. Add stubs for some new display manager API features. Start to split apart the concepts of display id and layer stack. since they operate at different layers of abstraction. While it's true that each logical display uniquely corresponds to a surface flinger layer stack, it is not necessarily the case that they must use the same ids. Added Display.getLayerStack() and started using it in places where it was relatively easy to do. Change-Id: I29ed909114dec86807c4d3a5059c3fa0358bea61

Fix issue #5371530: SYSTEMUI_FLAG_HIDE_NAVIGATION reasserts itself immediately This cleans up how ui flags are managed between the client and window manager. It still reports the global UI mode state to the callback, but we now only clear certain flags when the system goes out of a state (currently this just means the hide nav bar mode), and don't corrupt other flags in the application when the global state changes. Also introduces a sequence number between the app and window manager, to avoid using bad old data coming from the app during these transitions. Change-Id: I40bbd12d9b7b69fc0ff1c7dc0cb58a933d4dfb23

Drag/drop APIs and infrastructure 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. Change-Id: Ia8d0fb1516bce8c735d87ffd101af0976d7e84b6

Native input dispatch rewrite work in progress. 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. Change-Id: I8c36b2b9e0a2d27392040ecda0f51b636456de25

Some optizations to wallpaper drawing/scrolling. First, fix some issues with the final wallpaper bitmap we use: ensure it is always 16bpp, and make sure dithering of its bitmap is turned off. We take of dithering when loading, to make sure we don't use it when drawing. Also add new APIs to return the wallpaper with the equivalent of Launcher's old FastBitmapDrawable. As doing this, also load the default wallpaper the same way as custom ones, taking care to resize it as needed at load time. Finally implement a mechanism for the window manager to wait for the wallpaper to redraw at its new position before returning from the application's call to change the offset. This ensures that the wallpaper better tracks the application. Note that there is a timeout in this wait that is relatively short, and if it expires we will run for a while without waiting.
