I just encountered the following problem while I was testing my application with the Titanium Studio emulator : touch screen only works with Titanium SDK lower than 1.7.2.
I'm using Titanium Studio build 126.96.36.199204132053, Titanium SDK 2.0.1.GA2 (Android Runtime V8) and Google APIs Android 4.0.3. If I use Titanium SDK 1.7.2 touch screen works just fine, but if I try with a newer version of the SDK it does't work. On my computer I have Ubuntu 11.10 with Linux Kernel 3.3. Is there anyone else who has my same problem with touch-screen? HELP!!!!
Often when a touch event is not registering as one would expect, there is another view's event handler that is intercepting the event because of overlay/zindex conflicts.
In 2.0.1, the layout defaults for most of the UI items has changed, which may place a newly added object in front of an existing item. Titanium 2.0 Layout Changes
