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" } ] }
