I've just started looking at doing some basic mobile web development on the android and an writing a test script to investigate the touch events. I've run the following code in the android emulator, and the touchend event never gets fired. Can anyone tell me why ?
I've tried in three versions of the emulator (1.6, 2.1 and 2.2) and all three behave in the same way.
Thanks in advance for any help you can give me.
Cheers, Colm
EDIT - I've also tried this using the XUI framework and have the same problem so I'm guessing I have a fundamental misunderstanding of how this stuff works ......
