pinchzoom

Can multi-touch events be tested on the Android Emulator? Or is there any way to test this without an actual device? I am using the 2.0 sdk and want to test zoom-in/zoom-out with two fingers.

I'm using storyboard (iOS 6.0) to create a photo gallery viewer for my app. This is how my imageViewController is set up in storyboard: I've made sure to enable userInteraction and multiple touches on both the imageView and scrollView.
