replicant-frameworks_native/libs/ui/tests/InputReader_test.cpp
Jeff Brown 3c3cc62e24 Add unit tests for native input and fix bugs identified. 
Fixed a bug where we would lose the first touch point when swiping out of
the virtual key area.

Fixed a bug where we would not send an ACTION_MOVE event in cases where
individual pointers went down/up and the remaining pointers actually moved.
This is important since many applications do not handle pointer movements
during ACTION_POINTER_DOWN or ACTION_POINTER_UP.  In the case of
ACTION_POINTER_UP the movement was completely lost since all pointers were
dispatched using their old location rather than the new location.

Improved motion event validation to check for duplicate pointer ids.

Added an input source constant that was missing from the NDK api but
defined in the framework api.

Added a timestamp when reporting added/removed devices in EventHub.

Bug: 3070082
