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

Refactor input reader to support new device types more easily. Refactored the input reader so that each raw input protocol is handled by a separate subclass of the new InputMapper type. This way, behaviors pertaining to keyboard, trackballs, touchscreens, switches and other devices are clearly distinguished for improved maintainability. Added partial support for describing capabilities of input devices (incomplete and untested for now, will be fleshed out in later commits). Simplified EventHub interface somewhat since InputReader is taking over more of the work. Cleaned up some of the interactions between InputManager and WindowManagerService related to reading input state. Fixed swiping finger from screen edge into display area. Added logging of device information to 'dumpsys window'. Change-Id: I17faffc33e3aec3a0f33f0b37e81a70609378612

Input device calibration and capabilities. Finished the input device capability API. Added a mechanism for calibrating touch devices to obtain more accurate information about the touch contact area. Improved pointer location to show new coordinates and capabilities. Optimized pointer location display and formatting to avoid allocating large numbers of temporary objects. The GC churn was causing the application to stutter very badly when more than a couple of fingers were down). Added more diagnostics. Change-Id: Ie25380278ed6f16c5b04cd9df848015850383498

Input dispatcher ANR handling enhancements. This change is essentially a rewrite of the main input dispatcher loop with the target identification folded in. Since the input dispatcher now has all of the window state, it can make better decisions about when to ANR. Added a .5 second deadline for processing app switch keys. This behavior predates Gingerbread but had not previously been ported. Fixed some timing inaccuracies in the ANR accounting that could cause applications to ANR sooner than they should have. Added a mechanism for tracking key and motion events that have been dispatched to a window so that appropriate cancelation events can be synthesized when recovering from ANR. This change helps to keep applications in sync so they don't end up with stuck buttons upon recovery from ANRs. Added more comments to describe the tricky parts of PollLoop.

Add unit tests for native input and fix bugs identified. Fixed a bug where we would lose the first touch point when swiping out of the virtual key area. Fixed a bug where we would not send an ACTION_MOVE event in cases where individual pointers went down/up and the remaining pointers actually moved. This is important since many applications do not handle pointer movements during ACTION_POINTER_DOWN or ACTION_POINTER_UP. In the case of ACTION_POINTER_UP the movement was completely lost since all pointers were dispatched using their old location rather than the new location. Improved motion event validation to check for duplicate pointer ids. Added an input source constant that was missing from the NDK api but defined in the framework api. Added a timestamp when reporting added/removed devices in EventHub. Bug: 3070082 Change-Id: I3206a030f43b7616e2f48006e5a9d522c4d92e56

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).

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).

Refactor input reader to support new device types more easily. Refactored the input reader so that each raw input protocol is handled by a separate subclass of the new InputMapper type. This way, behaviors pertaining to keyboard, trackballs, touchscreens, switches and other devices are clearly distinguished for improved maintainability.

Add unit tests for native input and fix bugs identified. Fixed a bug where we would lose the first touch point when swiping out of the virtual key area. Fixed a bug where we would not send an ACTION_MOVE event in cases where individual pointers went down/up and the remaining pointers actually moved. This is important since many applications do not handle pointer movements during ACTION_POINTER_DOWN or ACTION_POINTER_UP. In the case of ACTION_POINTER_UP the movement was completely lost since all pointers were dispatched using their old location rather than the new location. Improved motion event validation to check for duplicate pointer ids. Added an input source constant that was missing from the NDK api but defined in the framework api. Added a timestamp when reporting added/removed devices in EventHub. Bug: 3070082 Change-Id: I3206a030f43b7616e2f48006e5a9d522c4d92e56

Input dispatcher ANR handling enhancements. This change is essentially a rewrite of the main input dispatcher loop with the target identification folded in. Since the input dispatcher now has all of the window state, it can make better decisions about when to ANR. Added a .5 second deadline for processing app switch keys. This behavior predates Gingerbread but had not previously been ported. Fixed some timing inaccuracies in the ANR accounting that could cause applications to ANR sooner than they should have. Added a mechanism for tracking key and motion events that have been dispatched to a window so that appropriate cancelation events can be synthesized when recovering from ANR. This change helps to keep applications in sync so they don't end up with stuck buttons upon recovery from ANRs. Added more comments to describe the tricky parts of PollLoop.

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

void process(const RawEvent* rawEvent);
Refactor input reader to support new device types more easily. Refactored the input reader so that each raw input protocol is handled by a separate subclass of the new InputMapper type. This way, behaviors pertaining to keyboard, trackballs, touchscreens, switches and other devices are clearly distinguished for improved maintainability. Added partial support for describing capabilities of input devices (incomplete and untested for now, will be fleshed out in later commits). Simplified EventHub interface somewhat since InputReader is taking over more of the work. Cleaned up some of the interactions between InputManager and WindowManagerService related to reading input state. Fixed swiping finger from screen edge into display area. Added logging of device information to 'dumpsys window'. Change-Id: I17faffc33e3aec3a0f33f0b37e81a70609378612

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.

Each input target is specified by its input channel and some parameters including flags, an X/Y coordinate offset, and the dispatch timeout.

void consumeEvent(const RawEvent* rawEvent);
Add unit tests for native input and fix bugs identified. Fixed a bug where we would lose the first touch point when swiping out of the virtual key area. Fixed a bug where we would not send an ACTION_MOVE event in cases where individual pointers went down/up and the remaining pointers actually moved. This is important since many applications do not handle pointer movements during ACTION_POINTER_DOWN or ACTION_POINTER_UP. In the case of ACTION_POINTER_UP the movement was completely lost since all pointers were dispatched using their old location rather than the new location. Improved motion event validation to check for duplicate pointer ids. Added an input source constant that was missing from the NDK api but defined in the framework api. Added a timestamp when reporting added/removed devices in EventHub. Bug: 3070082 Change-Id: I3206a030f43b7616e2f48006e5a9d522c4d92e56

Add unit tests for native input and fix bugs identified. Fixed a bug where we would lose the first touch point when swiping out of the virtual key area. Fixed a bug where we would not send an ACTION_MOVE event in cases where individual pointers went down/up and the remaining pointers actually moved. This is important since many applications do not handle pointer movements during ACTION_POINTER_DOWN or ACTION_POINTER_UP. In the case of ACTION_POINTER_UP the movement was completely lost since all pointers were dispatched using their old location rather than the new location. Improved motion event validation to check for duplicate pointer ids. Added an input source constant that was missing from the NDK api but defined in the framework api. Added a timestamp when reporting added/removed devices in EventHub. Bug: 3070082 Change-Id: I3206a030f43b7616e2f48006e5a9d522c4d92e56

Refactor input reader to support new device types more easily. Refactored the input reader so that each raw input protocol is handled by a separate subclass of the new InputMapper type. This way, behaviors pertaining to keyboard, trackballs, touchscreens, switches and other devices are clearly distinguished for improved maintainability. Added partial support for describing capabilities of input devices (incomplete and untested for now, will be fleshed out in later commits). Simplified EventHub interface somewhat since InputReader is taking over more of the work. Cleaned up some of the interactions between InputManager and WindowManagerService related to reading input state. Fixed swiping finger from screen edge into display area. Added logging of device information to 'dumpsys window'. Change-Id: I17faffc33e3aec3a0f33f0b37e81a70609378612

Fix some input device mapping bugs with certain drivers. On single-touch devices, pointer up/down is signalled by a BTN_TOUCH key event. Previously we handled BTN_TOUCH immediately but some drivers may produce the sequence BTN_TOUCH, ABS_X, ABS_Y, SYN_REPORT on pointer down which caused us to emit a bad initial pointer down location. Now we wait for SYN_REPORT before reporting the up or down. On multi-touch devices, pointer up can be signalled by as little as the sequence SYN_MT_REPORT, SYN_REPORT. This change ensures that we handle this case. Added support for reading ABS_MT_PRESSURE when available. Corrected mapping of touchMajor/touchMinor on single touch devices. Minor code cleanup.

Refactor input reader to support new device types more easily. Refactored the input reader so that each raw input protocol is handled by a separate subclass of the new InputMapper type. This way, behaviors pertaining to keyboard, trackballs, touchscreens, switches and other devices are clearly distinguished for improved maintainability. Added partial support for describing capabilities of input devices (incomplete and untested for now, will be fleshed out in later commits). Simplified EventHub interface somewhat since InputReader is taking over more of the work. Cleaned up some of the interactions between InputManager and WindowManagerService related to reading input state. Fixed swiping finger from screen edge into display area. Added logging of device information to 'dumpsys window'. Change-Id: I17faffc33e3aec3a0f33f0b37e81a70609378612

Input device calibration and capabilities. Finished the input device capability API. Added a mechanism for calibrating touch devices to obtain more accurate information about the touch contact area. Improved pointer location to show new coordinates and capabilities. Optimized pointer location display and formatting to avoid allocating large numbers of temporary objects.

Fix some input device mapping bugs with certain drivers. On single-touch devices, pointer up/down is signalled by a BTN_TOUCH key event. Previously we handled BTN_TOUCH immediately but some drivers may produce the sequence BTN_TOUCH, ABS_X, ABS_Y, SYN_REPORT on pointer down which caused us to emit a bad initial pointer down location. Now we wait for SYN_REPORT before reporting the up or down. On multi-touch devices, pointer up can be signalled by as little as the sequence SYN_MT_REPORT, SYN_REPORT. This change ensures that we handle this case. Added support for reading ABS_MT_PRESSURE when available. Corrected mapping of touchMajor/touchMinor on single touch devices. Minor code cleanup.

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
