Add initial API for stylus and mouse buttons. Added the concept of pointer properties in a MotionEvent. This is currently used to track the pointer tool type to enable applications to distinguish finger touches from a stylus. Button states are also reported to application as part of touch events. There are no new actions for detecting changes in button states. The application should instead query the button state from the MotionEvent and take appropriate action as needed. A good time to check the button state is on ACTION_DOWN. As a side-effect, applications that do not support multiple buttons will treat primary, secondary and tertiary buttons identically for all touch events. The back button on the mouse is mapped to KEYCODE_BACK and the forward button is mapped to KEYCODE_FORWARD. Added basic plumbing for the secondary mouse button to invoke the context menu, particularly in lists. Added clamp and split methods on MotionEvent to take care of common filtering operations so we don't have them scattered in multiple places across the framework.

Add support for fallback keycodes. This change enables the framework to synthesize key events to implement default behavior when an application does not handle a key. For example, this change enables numeric keypad keys to perform their associated special function when numlock is off. The application is informed that it is processing a fallback keypress so it can choose to ignore it. Added a new keycode for switching applications. Added ALT key deadkeys. New default key mappings: - ESC -> BACK - Meta+ESC -> HOME - Alt+ESC -> MENU - Meta+Space -> SEARCH - Meta+Tab -> APP_SWITCH Fixed some comments. Fixed some tests.

Tell system server whether the app handled input events. Refactored ViewRoot, NativeActivity and related classes to tell the dispatcher whether an input event was actually handled by the application. This will be used to move more of the global default key processing into the system server instead of the application. Change-Id: If06b98b6f45c543e5ac5b1eae2b3baf9371fba28

Replace epoll() with poll() and rename PollLoop to Looper. As part of this change, consolidated and cleaned up the Looper API so that there are fewer distinctions between the NDK and non-NDK declarations (no need for two callback types, etc.). Removed the dependence on specific constants from sys/poll.h such as POLLIN. Instead looper.h defines events like LOOPER_EVENT_INPUT for the events that it supports. That should help make any future under-the-hood implementation changes easier. Fixed a couple of compiler warnings along the way. Change-Id: I449a7ec780bf061bdd325452f823673e2b39b6ae

Add support for secure views. Added the MotionEvent.FLAG_WINDOW_IS_OBSCURED flag which is set by the input manager whenever another visible window is partly or wholly obscured the target of a touch event so that applications can filter touches accordingly. Added a "filterTouchesWhenObscured" attribute to View which can be used to enable filtering of touches when the view's window is obscured. Change-Id: I936d9c85013fd2d77fb296a600528d30a29027d2

Add support for new input sources. Added several new coordinate values to MotionEvents to capture touch major/minor area, tool major/minor area and orientation. Renamed NDK input constants per convention. Added InputDevice class in Java which will eventually provide useful information about available input devices. Added APIs for manufacturing new MotionEvent objects with multiple pointers and all necessary coordinate data. Fixed a bug in the input dispatcher where it could get stuck with a pointer down forever. Fixed a bug in the WindowManager where the input window list could end up containing stale removed windows. Fixed a bug in the WindowManager where the input channel was being removed only after the final animation transition had taken place which caused spurious WINDOW DIED log messages to be printed.

IME events are now dispatched to native applications. And also: - APIs to show and hide the IME, and control its interaction with the app. - APIs to tell the app when its window resizes and needs to be redrawn. - API to tell the app the content rectangle of its window (to layout around the IME or status bar). There is still a problem with IME interaction -- we need a way for the app to deliver events to the IME before it handles them, so that for example the back key will close the IME instead of finishing the app. Change-Id: I37b75fc2ec533750ef36ca3aedd2f0cc0b5813cd

Add new native Looper API. This allows us to avoid exposing the file descriptor of the event queue; instead, you attach an event queue to a looper. This will also should allow native apps to be written without the need for a separate thread, by attaching the event queue to the main thread's looper and scheduling their own messages there.

Implement default key handling for native code. The native code now maintains a list of all keys that may use default handling. If the app finishes one of these keys without handling it, the key will be passed back off to Java for default treatment. Change-Id: I6a842a0d728eeafa4de7142fae573f8c11099e18

First stab at attaching native event dispatching. Provides the basic infrastructure for a NativeActivity's native code to get an object representing its event stream that can be used to read input events. Still work to do, probably some API changes, and reasonable default key handling (so that for example back will still work). Change-Id: I6db891bc35dc9683181d7708eaed552b955a077e

Even more native input dispatch work in progress. Added more tests. Fixed a regression in Vector. Fixed bugs in pointer tracking. Fixed a starvation issue in PollLoop when setting or removing callbacks. Fixed a couple of policy nits. Modified the internal representation of MotionEvent to be more efficient and more consistent. Added code to skip/cancel virtual key processing when there are multiple pointers down. This helps to better disambiguate virtual key presses from stray touches (such as cheek presses).

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
