Hi: I am new on Android and I would like to know if there is an API to catch the events to handle multitouch, detect the zoom,rotate and slide gesture. I want to make an application like Gallery. I was checking on google , they use on touch event and MotionEvent.ACTION_MASK to detect when one finger is press, release, or when 2 touch are press, but seems to be not easy to detect rotate gesture. Is there an other API to detect those events??, or some code that i can use as reference to get when a rotate and zoom gesture are done?? Thanks too much for your help..
