问题
im writing an application that uses only native code.
So is it possible to get multitouch events in ndk?
I feel like ive serched the whole web, but without finding anything!
Does anyone know how to do this?

Yes, it is.
You can check example called native-activity
to see how to get input events. Look for engine_handle_input
function. AInputEvent_getType
function returns type of event. If it is AINPUT_EVENT_TYPE_MOTION
then using AKeyEvent_getAction
function you can get different information about touch event. Use the AMOTION_EVENT_ACTION_MASK
, AMOTION_EVENT_ACTION_POINTER_INDEX_MASK
, AMOTION_EVENT_ACTION_POINTER_DOWN
and AMOTION_EVENT_ACTION_POINTER_UP
enums in same way you use them in Java API: http://android-developers.blogspot.com/2010/06/making-sense-of-multitouch.html
