Oh, Jesus. I finally find the answers: Please take reference for this site.

If you work on an Android System,remember the 'touchmove' only fire ONCE as your finger moves around the pad. So if you wanna draw a line or something, you have to do this:

function onStart ( touchEvent ) {
if( navigator.userAgent.match(/Android/i) ) {   // if you already work on Android system, you can        skip this step
touchEvent.preventDefault();     //THIS IS THE KEY. You can read the difficult doc released by W3C to learn more.
}

And if you have more time, you can read the W3C's document about introducing the 'movetouch', it is REALLY hard to understand. The doc sucks.
