title: The "touchmove" event on android system: Transformer Prime
body: <p>I am working on a Transformer Pad and developing a drawing plate. 
  I use PhoneGap(javascript) to write the code instead of JAVA. </p>
  
  <p>But the touchmove event is quite weird. </p>
  
  <p>I think as I move my finger on the pad, it will continuously to collect the coordinates which I 
  touch on the canvas. BUT IT DOES NOT!
  It's ridiculous, it only collect "1" coordinate: the first point on the canvas my finger moves to. </p>
  
  <p>Here are my code about the "Touch &amp;&amp; Move event":</p>
  
  <pre><code>function touchStart(event){
      if (event.targetTouches.length == 1) {
      var touch = event.targetTouches[0];     
  
          if (event.type == "touchstart") {
              line_start_x= touch.pageX-  canvas_org_x;
              line_start_y= touch.pageY-  canvas_org_y;
              context.beginPath();                        
              context.moveTo(line_start_x, line_start_y); 
  
          }//if           
      }//if 1
  }//function.
  
  function Touch_Move(event){
      line_end_x= event.touches[0].pageX-  canvas_org_x;
                  line_end_y= event.touches[0].pageY-  canvas_org_y;
                  context.lineTo(line_end_x, line_end_y);
                  context.stroke();
                  test++;                 
  }
  </code></pre>
  
  <p>I don't know why each time I move my finger on the pad, trying to draw a line, curve, or anything
  I want. As the finger moves, only a VERY SHORT segment appears. So I declare a variable:"var test=0" in the beginning of this js file. I found that although I move my finger on the pad without leaving it or stopping, the value of "test" remains 1. It means that I move my finger on it. But it doesn't
  continuously to trigger the event: "Touch_Move".</p>
  
  <p>What can I do now? I need a corresponding event to "mousemove" on touch pad. At least, the event has to continuously be triggered.</p>
