For compatibility reasons, the window will\n*also* receive the HOVER_MOVE. When the pointer moves into a different\nwindow or the pointer goes down or when events are canceled for some reason,\nthe input dispatcher sends a HOVER_EXIT to the previously hovered window.\n\nThe view hierarchy behavior is similar. All views under the pointer\nreceive onHoverEvent with HOVER_ENTER followed by any number of HOVER_MOVE\nevents. When the pointer leaves a view, the view receives HOVER_EXIT.\nSimilarly, if a parent view decides to capture hover by returning true\nfrom onHoverEvent, the hovered descendants will receive HOVER_EXIT.\n\nThe default behavior of onHoverEvent is to update the view\u0027s hovered\nstate by calling setHovered(true/false). Views can query their current\nhovered state using isHovered().\n\nFor testing purposes, the hovered state is mapped to the pressed\ndrawable state. This will change in a subsequent commit with the\nintroduction of a new hovered drawable state.\n\nChange-Id: Ib76a7a90236c8f2c7336e55773acade6346cacbe\n" }, { "commit": "56194ebec6212e229f4ccdaa4b187166d20013ef", "tree": "51276000061ba703b6ddda32ecce3ce10a06f4f5", "parents": [ "05dc66ada6b61a6bdf806ffaa62617ac5394695d" ], "author": { "name": "Jeff Brown", "email": "jeffbrown@google.com", "time": "Wed Mar 02 19:23:13 2011 -0800" }, "committer": { "name": "Jeff Brown", "email": "jeffbrown@google.com", "time": "Wed Mar 02 19:57:07 2011 -0800" }, "message": "Wake screen from external HID peripherals.\n\nAdded some plumbing to enable the policy to intercept motion\nevents when the screen is off to handle wakeup if needed.\n\nAdded a basic concept of an external device to limit the scope\nof the wakeup policy to external devices only.

However, it can happen\nthat an input channel is disposed and then a new input channel is\nimmediately created that reuses the same file descriptor. Ordinarily\nthis is not a problem, however there is a small opportunity for a race\nto arise in InputQueue.\n\nWhen InputQueue receives an input event from the dispatcher, it\ngenerates a finishedToken that encodes the channel\u0027s receive pipe fd,\nand a sequence number. The finishedToken is used by the ViewRoot\nas a handle for the event so that it can tell the InputQueue when\nthe event has finished being processed.\n\nHere is the race:\n\n1. InputQueue receives an input event, assigns a new finishedToken.\n2. ViewRoot begins processing the input event.\n3. During processing, ViewRoot unregisters the InputChannel.\n4. A new InputChannel is created and is registered with the Input Queue.\n This InputChannel happens to have the same receive pipe fd as\n the one previously registered.\n5. ViewRoot tells the InputQueue that it has finished processing the\n input event, passing along the original finishedToken.\n6. InputQueue throws an exception because the finishedToken\u0027s receive\n pipe fd is registered but the sequence number is incorrect so it\n assumes that the client has called finish spuriously.\n\nThe fix is to include a unique connection id within the finishedToken so\nthat the InputQueue can accurately confirm that the token belongs to\nthe currently registered InputChannel rather than to an old one that\nhappened to have the same receive pipe fd. When it notices this, it\nignores the spurious finish.\n\nI\u0027ve also made a couple of other small changes to avoid similar races\nelsewhere.\n\nThis patch set also includes a fix to synthesize a finished signal\nwhen the input channel is unregistered on the client side to\nhelp keep the server and client in sync.\n\nBug: 2834068\nChange-Id: I1de34a36249ab74c359c2c67a57e333543400f7b\n" }, { "commit": "6ec402b5ae33c8927694d8522b4cc6a5c8ba974e", "tree": "5d4b19eda9ade71d7e34635479426f1dd484e8c2", "parents": [ "6dea6f4e71b53e421564d783c227cbe0a2469183" ], "author": { "name": "Jeff Brown", "email": "jeffbrown@google.com", "time": "Wed Jul 28 15:48:59 2010 -0700" }, "committer": { "name": "Jeff Brown", "email": "jeffbrown@google.com", "time": "Thu Jul 29 12:54:27 2010 -0700" }, "message": "DO NOT MERGE: Fix input event injection ANRs on UI thread.\n\nAdded a new asynchronous injection mode and made the existing\nsynchronization mechanism more robust.\n\nChange-Id: Ia4aa04fd9b75ea2461a844c5b7933c831c1027e6\n" }, { "commit": "c5ed5910c9ef066cec6a13bbb404ec57b1e92637", "tree": "b06dfdac2d807dae78a2634007b6e627eefd0804", "parents": [ "d9452ecd0ce6c8e0518055929ba1fd0712146405" ], "author": { "name": "Jeff Brown", "email": "jeffbrown@google.com", "time": "Wed Jul 14 18:48:53 2010 -0700" }, "committer": { "name": "Jeff Brown", "email": "jeffbrown@google.com", "time": "Thu Jul 15 18:32:33 2010 -0700" }, "message": "Add support for new input sources.\n\nAdded several new coordinate values to MotionEvents to capture\ntouch major/minor area, tool major/minor area and orientation.\n\nRenamed NDK input constants per convention.\n\nAdded InputDevice class in Java which will eventually provide\nuseful information about available input devices.\n\nAdded APIs for manufacturing new MotionEvent objects with multiple\npointers and all necessary coordinate data.\n\nFixed a bug in the input dispatcher where it could get stuck with\na pointer down forever.\n\nFixed a bug in the WindowManager where the input window list could\nend up containing stale removed windows.\n\nFixed a bug in the WindowManager where the input channel was being\nremoved only after the final animation transition had taken place\nwhich caused spurious WINDOW DIED log messages to be printed.\n\nChange-Id: Ie55084da319b20aad29b28a0499b8dd98bb5da68\n" }, { "commit": "349703effce5acc53ed96f7ed8556131f0c65e18", "tree": "359217d5076e3005c724b2117a59ffec81e7a83b", "parents": [ "f2b544f5ae7676f7ab4cdf3379b2ed3c60a65def" ], "author": { "name": "Jeff Brown", "email": "jeffbrown@google.com", "time": "Tue Jun 22 01:27:15 2010 -0700" }, "committer": { "name": "Jeff Brown", "email": "jeffbrown@google.com", "time": "Mon Jun 28 19:10:54 2010 -0700" }, "message": "Native input event dispatching.\n\nTarget identification is now fully native.\nFixed a couple of minor issues related to input injection.\nNative input enabled by default, can be disabled by setting\nWindowManagerPolicy.ENABLE_NATIVE_INPUT_DISPATCH to false.\n\nChange-Id: I7edf66ed3e987cc9306ad4743ac57a116af452ff\n" }, { "commit": "7fbdc84e87dd3a0e196b9803bb04495d11e9cb8a", "tree": "32691f639ef71365b602795db215f11f457397a5", "parents": [ "e47e3f3855a062ba0338a57eeda2f12a0f7a1fa8" ], "author": { "name": "Jeff Brown", "email": "jeffbrown@google.com", "time": "Thu Jun 17 20:52:56 2010 -0700" }, "committer": { "name": "Jeff Brown", "email": "jeffbrown@google.com", "time": "Mon Jun 21 13:59:34 2010 -0700" }, "message": "More native input event dispatching.\n\nAdded ANRs handling.\nAdded event injection.\nFixed a NPE ActivityManagerServer writing ANRs to the drop box.\nFixed HOME key interception.\nFixed trackball reporting.\nFixed pointer rotation in landscape mode.\n\nChange-Id: I50340f559f22899ab924e220a78119ffc79469b7\n" }, { "commit": "9c3cda04d969912bc46184f2b326d1db95e0aba5", "tree": "cdeb4a4bfa83aa335ab840969fe214058a0d566e", "parents": [ "60e8c33d6f6caad2e963e91abca16a85cd3be82a" ], "author": { "name": "Jeff Brown", "email": "jeffbrown@google.com", "time": "Tue Jun 15 01:31:58 2010 -0700" }, "committer": { "name": "Jeff Brown", "email": "jeffbrown@google.com", "time": "Tue Jun 15 16:43:18 2010 -0700" }, "message": "More work in progress on native events.\n\nRefactored the code to eliminate potential deadlocks due to re-entrant\ncalls from the policy into the dispatcher.

To enable native input dispatch,\nedit the ENABLE_NATIVE_DISPATCH constant in WindowManagerPolicy.\n\nIncludes part of the new input event NDK API. Some details TBD.\n\nTo wire up input dispatch, as the ViewRoot adds a window to the\nwindow session it receives an InputChannel object as an output\nargument. The InputChannel encapsulates the file descriptors for a\nshared memory region and two pipe end-points. The ViewRoot then\nprovides the InputChannel to the InputQueue. Behind the\nscenes, InputQueue simply attaches handlers to the native PollLoop object\nthat underlies the MessageQueue. This way MessageQueue doesn\u0027t need\nto know anything about input dispatch per-se, it just exposes (in native\ncode) a PollLoop that other components can use to monitor file descriptor\nstate changes.\n\nThere can be zero or more targets for any given input event. Each\ninput target is specified by its input channel and some parameters\nincluding flags, an X/Y coordinate offset, and the dispatch timeout.\nAn input target can request either synchronous dispatch (for foreground apps)\nor asynchronous dispatch (fire-and-forget for wallpapers and \"outside\"\ntargets). Currently, finding the appropriate input targets for an event\nrequires a call back into the WindowManagerServer from native code.\nIn the future this will be refactored to avoid most of these callbacks\nexcept as required to handle pending focus transitions.\n\nEnd-to-end event dispatch mostly works!\n\nTo do: event injection, rate limiting, ANRs, testing, optimization, etc.\n\nChange-Id: I8c36b2b9e0a2d27392040ecda0f51b636456de25\n" } ] }
