Android:Multi touch doesn't work as expected?

Question

Hi folks,

Help me in resolving the below issue.

I have three image buttons on screen. All these three buttons controlled under ontouchlistner as below.

buttonOne.setOnTouchListener(this); buttonTwo.setOnTouchListener(this); buttonThree.setOnTouchListener(this);

I override "public boolean onTouch(View v, MotionEvent event)". Under this i check for these three image buttons touch events like below.

ImageButton imageBtn = (ImageButton) v; 

  if ( imageBtn == buttonOne ) // first button touch 
                ..Log.. 
            else if ( imageBtn == buttonTwo ) 
                 ..Log.. 
  else if ( imageBtn == buttonThree ) // first button touch 
                ..Log.. 

My problem is, as it is under multi touch event handler like above, it does not detect when touch all three button at a time to try to produce multi touch effect, instead it detects only one imagebutton touch at a time even though i touch all three image buttons. As i am developing this project on Android 1.6 SDK, is there any problem accessing my requirement(multi touch) (or) it is a known issue? I am hoping that, when it works for single button touch, why shouldn't it work when clicking three imagebuttons at a time to produce three logs printed as per my above code?

How do i resolve it for my case?

Please don't question me why i am still developing on 1.6 for such a requirement.

Thank you. Appreciate your suggestions !

I believe the multitouch support in 1.6 is limited to gestures. You might need to develop for android 2.x to get full multitouch support.
