* Improve VelocityTracker numerical stability.Jeff Brown2011-03-151-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | Replaced VelocityTracker with a faster and more accurate native implementation. This avoids the duplicate maintenance overhead of having two implementations. The new algorithm requires that the sample duration be at least 10ms in order to contribute to the velocity calculation. This ensures that the velocity is not severely overestimated when samples arrive in bursts. The new algorithm computes the exponentially weighted moving average using weights based on the relative duration of successive sample periods. The new algorithm is also more careful about how it handles individual pointers going down or up and their effects on the collected movement traces. The intent is to preserve the last known velocity of pointers as they go up while also ensuring that other motion samples do not count twice in that case.

* Use touch pad gestures to manipulate the pointer.Jeff Brown2011-03-141-0/+6
| | | | | | | | | | | | | | | | | | | | 1. Single finger tap performs a click. 2. Single finger movement moves the pointer (hovers). 3. Button press plus movement performs click or drag. While dragging, the pointer follows the finger that is moving fastest. This is important if there are additional fingers down on the touch pad for the purpose of applying force to an integrated button underneath. 4. Two fingers near each other moving in the same direction are coalesced as a swipe gesture under the pointer. 5. Two or more fingers moving in arbitrary directions are transformed into touches in the vicinity of the pointer. This makes scale/zoom and rotate gestures possible. Added a native VelocityTracker implementation to enable intelligent switching of the active pointer during drags. Change-Id: I5ada57e7f2bdb9b0a791843eb354a8c706b365dc

| * | Fix some issues with RefBase debugging.Mathias Agopian2011-02-233-189/+325
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | First slipt sp<> out of RefBase into StrongPointer.h so it can be reused more easily and to make it clear that it doesn't require RefBase. Note: the rest of the change only affects the system when DEBUG_REFS is enabled. The main problem we fix here is that the owner id associated with each reference could get out of date when a sp<> or wp<> was moved, for instance when they're used in a Vector< >. We fix this issue by calling into RefBase::moveReferences from a template specialization for sp<TYPE> and wp<TYPE> of the type helpers. RefBase::moveReferences() has then a chance to update the owner ids. There is a little bit of trickery to implement this generically in RefBase, where we need to use a templatized functor that can turn a sp<TYPE>* casted to a void* into a RefBase*. Introduced a new debug option DEBUG_REFS_FATAL_SANITY_CHECKS currently set to 0 by default as there seem to be an issue with sp<ANativeWindow> which trips the sanity checks.

* | Use optimized display lists for all hwaccelerated renderingChet Haase2011-01-241-0/+33
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, display lists were used only if hardware acceleration was enabled for an application (hardwareAccelerated=true) *and* if setDrawingCacheEnabled(true) was called. This change makes the framework use display lists for all views in an application if hardware acceleration is enabled. In addition, display list renderering has been optimized so that any view's recreation of its own display list (which is necessary whenever the visuals of that view change) will not cause any other display list in its parent hierarchy to change. Instead, when there are any visual changes in the hierarchy, only those views which need to have new display list content will recreate their display lists. This optimization works by caching display list references in each parent display list (so the container of some child will refer to its child's display list by a reference to the child's display list). Then when a view needs to recreate its display list, it will do so inside the same display list object. This will cause the content to get refreshed, but not the reference to that content. Then when the view hierarchy is redrawn, it will automatically pick up the new content from the old reference. This optimization will not necessarily improve performance when applications need to update the entire view hierarchy or redraw the entire screen, but it does show significant improvements when redrawing only a portion of the screen, especially when the regions that are not refreshed are complex and time- consuming to redraw.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Use Vendor ID, Product ID and optionally the Version to locate keymaps and configuration files for external devices. Moved virtual key definition parsing to native code so that EventHub can identify touch screens with virtual keys and load the appropriate key layout file. Cleaned up a lot of old code in EventHub. Fixed a regression in ViewRoot's fallback event handling. Fixed a minor bug in FileMap that caused it to try to munmap or close invalid handled when released if the attempt to map the file failed. Added a couple of new String8 conveniences for formatting strings. Modified Tokenizer to fall back to open+read when mmap fails since we can't mmap sysfs files as needed to open the virtual key definition files in /sys/board_properties/.

* | Support non-orientation aware keyboards and other devices.Jeff Brown2010-11-301-0/+100
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fixed a bug with dpad keys on external keyboards being rotated according to the display orientation by adding a new input device configuration property called "keyboard.orientationAware". Added a mechanism for overriding the key layout and key character map in the input device configuration file using the new "keyboard.layout" and "keyboard.characterMap" properties. Also added "trackball.orientationAware", "touch.orientationAware" and "touch.deviceType" configuration properties. Rewrote the configuration property reading code in native code so that it can be used by EventHub and other components. Added basic support for installable idc, kl, and kcm files in /data/system/devices. However, there is no provision for copying files there yet. Disabled long-press character pickers on full keyboards so that key repeating works as expected. Change-Id: I1bd9f0c3d344421db444e7d271eb09bc8bab4791

Old key character maps will not work anymore and must be updated. The new format is plain text only and it not compiled to a binary file (so the "kcm" tool will be removed in a subsequent check-in). Added FULL keyboard type to support full PC-style keyboards. Added SPECIAL_FUNCTION keyboard type to support special function keypads that do not have any printable keys suitable for typing and only have keys like HOME and POWER Added a special VIRTUAL_KEYBOARD device id convention that maps to a virtual keyboard with a fixed known layout. This is designed to work around issues injecting input events on devices whose built-in keyboard does not have a useful key character map (ie. when the built-in keyboard is a special function keyboard only.) Modified several places where events were being synthesized to use the virtual keyboard. Removed support for the "qwerty" default layout. The new default layout is "Generic". For the most part "qwerty" was being used as a backstop in case the built-in keyboard did not have a key character map (probably because it was a special function keypad) and the framework needed to be able to inject key events anyways. The latter issue is resolved by using the special VIRTUAL_KEYBOARD device instead of BUILT_IN_KEYBOARD. Added the concept of a key modifier behavior so that MetaKeyKeyListener can distinguish between keyboards that use chorded vs. toggled modifiers. Wrote more robust key layout and key character map parsers to enable support for new keyboard features and user installable key maps. Fixed a bug in InputReader generating key ups when keys are released out of sequence. Updated tons of documentation. Currently QwertyKeyListener is being used for full keyboards with autotext and capitalization disabled. This mostly works but causes some problems with character pickers, etc. These issues will be resolved in subsequent changes. Change-Id: Ica48f6097a551141c215bc0d2c6f7b3fb634d354

If a drawable that's returned is not in the requested density, it will set it at the appropriate density to be scaled up later on. The API for this is hidden currently.

These maps are intended to be shared across devices by inheriting the "keyboards.mk" product makefile as part of the device's product definition. One of the trickier changes here was to unwind some code in MetaKeyKeyListener that assumed that only the low 8 bits of the meta key state were actually used. The new code abandons bitshifts in favor of simple conditionals that are probably easier to read anyways. The special meta key state constants used by MetaKeyKeyListener are now (@hide) defined in KeyEvent now so as to make it clearer that they share the same code space even if those codes are not valid for KeyEvents. The EventHub now takes care of detecting the appropriate key layout map and key character map when the device is added and sets system properties accordingly. This avoids having duplicate code in KeyCharacterMap to probe for the appropriate key character map although the current probing mechanism has been preserved for legacy reasons just in case. Added support for tracking caps lock, num lock and scroll lock and turning their corresponding LEDs on and off as needed. The key character map format will need to be updated to correctly support PC style external keyboard semantics related to modifier keys. That will come in a later change so caps lock doesn't actually do anything right now except turn the shiny LEDs on and off... Added a list of symbolic key names to KeyEvent and improved the toString() output for debug diagnosis. Having this list in a central place in the framework also allows us to remove it from Monkey so there is one less thing to maintain when we add new keycodes.

This creates a problem for determining the current file offset when using lseek() on those files, because you can't guarantee the cross-process locking of a mutex. Luckily, Linux implements pread() to get around this suckiness. The problem is that only Linux implements this, so we have to keep the old locking for use on host builds with aapt and friends. aapt doesn't have this same problem of sharing file descriptors across forked processes, so we can keep the local AutoMutex to protect accesses of those files.
