* Improve support for external keyboards.Jeff Brown2010-12-022-3/+12
| | | | | | | | | | | | | | | | | | | | | | | | | 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

* Added support for full PC-style keyboards.Jeff Brown2010-11-182-0/+125
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | BREAKING CHANGE: Redesigned the key character map format to accomodate full keyboards with more comprehensive suite of modifiers. 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

* Add path to get different DPI drawablesKenny Root2010-10-291-3/+5
| | | | | | | | | | | | | Allow a caller to request a different density than their current display allows. This can mean a device displaying mdpi can get a resource that's in hdpi and have it pretend to be in mdpi resolution. 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.

* | | Add keycodes and meta-key modifiers to support external keyboards.Jeff Brown2010-10-151-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Added new key maps for external keyboards. 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | AssetManager instances are created by zygote and passed to all its children so that they don't have to individually open frameworks-res.apk. 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.

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

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | This factors out the boiler-plate code from the sample app to a common glue code that can be used for everyone writing this style of app: a dedicated app thread that takes care of waiting for events and processing them.
