* Input device calibration and capabilities.Jeff Brown2010-08-303-23/+146
| | | | | | | | | | | | | 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

| * Fix some input device mapping bugs with certain drivers.Jeff Brown2010-08-181-14/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* | Keep track of remaining fd when devices are removedJens Gulin2010-08-181-0/+1
|/ | | | | | | | | | | Sometimes the wrong fd was accessed when the device was addressed by device id. The earlier implementation assumed that two arrays were in sync but one of them was compacted when devices were removed. Instead of that dependency the device now keeps track of it's file descriptor.

* Fix possible race conditions during channel unregistration.Jeff Brown2010-08-171-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, the input dispatcher assumed that the input channel's receive pipe file descriptor was a sufficiently unique identifier for looking up input channels in its various tables. However, it can happen that an input channel is disposed and then a new input channel is immediately created that reuses the same file descriptor. Ordinarily this is not a problem, however there is a small opportunity for a race to arise in InputQueue. When InputQueue receives an input event from the dispatcher, it generates a finishedToken that encodes the channel's receive pipe fd, and a sequence number. The finishedToken is used by the ViewRoot as a handle for the event so that it can tell the InputQueue when the event has finished being processed. Here is the race: 1. InputQueue receives an input event, assigns a new finishedToken. 2. ViewRoot begins processing the input event. 3. During processing, ViewRoot unregisters the InputChannel. 4. A new InputChannel is created and is registered with the Input Queue. This InputChannel happens to have the same receive pipe fd as the one previously registered. 5. ViewRoot tells the InputQueue that it has finished processing the input event, passing along the original finishedToken. 6. InputQueue throws an exception because the finishedToken's receive pipe fd is registered but the sequence number is incorrect so it assumes that the client has called finish spuriously. The fix is to include a unique connection id within the finishedToken so that the InputQueue can accurately confirm that the token belongs to the currently registered InputChannel rather than to an old one that happened to have the same receive pipe fd. When it notices this, it ignores the spurious finish. I've also made a couple of other small changes to avoid similar races elsewhere. This patch set also includes a fix to synthesize a finished signal when the input channel is unregistered on the client side to help keep the server and client in sync.

* Enhanced VelocityTracker for > 5 pointers and fixed bugs.Jeff Brown2010-07-301-1/+3
| | | | | | | | | | | | | Improved PointerLocation tool to use VelocityTracker more efficiently and correctly when multiple pointers are down. Fixed a bug in TouchInputMapper where it was not correctly copying the id to index map in the last touch data. This could cause strange behavior on secondary pointer up events. Also added finished callback pooling in InputQueue. Change-Id: Ia85e52ac2fb7350960ea1d7edfbe81a1b3e8267b

* Refactor input reader to support new device types more easily.Jeff Brown2010-07-285-544/+770
| | | | | | | | | | | | | | | | | | | | | | 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

* Implement native key pre-dispatching to IMEs.Dianne Hackborn2010-07-151-0/+2
| | | | | | | | | | | | | | | | This significantly re-works the native key dispatching code to allow events to be pre-dispatched to the current IME before being processed by native code. It introduces one new public API, which must be called after retrieving an event if the app wishes for it to be pre-dispatched. Currently the native code will only do pre-dispatching of system keys, to avoid significant overhead for gaming input. This should be improved to be smarted, filtering for only keys that the IME is interested in. Unfortunately IMEs don't currently provide this information. :p Change-Id: Ic1c7aeec8b348164957f2cd88119eb5bd85c2a9f
* Add support for new input sources.Jeff Brown2010-07-155-23/+109
| | | | | | | | | | | | | | | | | | | | | | | | | 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.Dianne Hackborn2010-07-132-27/+3
| | | | | | | | | | | | | | | 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.Dianne Hackborn2010-07-021-0/+5
|/ | | | | | | | | | | 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.

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.Jeff Brown2010-06-137-44/+1967
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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
