Hi Anastasiya, Using Yahel's code I made some proof of concepts to play around with the 'multitouch support' that is currently in the Google Cupcake code. I extended Yahel's code to determ if a second finger is added or released, which makes programming for multitouch a bit easier. The code can be found at my website: http://www.vanderbie.net/
The hack is not perfect though, so if you really want to fully support two finger multitouch you should extend my code further to get rid of the bugs. gr Joey On 17 aug, 22:41, Jason Proctor <[email protected]> wrote: > i'm not planning on including *any* multitouch support in a shipping > product. part of my job is developing gesture algorithms and writing > demonstration applications, for which i control the environment - > therefore a hacked kernel or even toString() is OK. > > at the moment, all i have is the distance-magnitude hack, which > mostly works but isn't great as you imagine. > > i hear all kinds of rumours about vendor-specific multitouch, most of > which i can't repeat. it would be great if the issue was sorted > before people have to start writing vendor-specific code. > > (note that the HTC Hero already has multitouch, but zoom only, which > maybe means it's built on the distance hack.) > > thanks, > j > > > > >I can't see the page that was posted, but the base framework doesn't > >print any second touch information in a MotionEvent, there is no > >such information there at all.
