Here is a very simple example to handle multitouch based on google docs.

@Override
public boolean onTouch(View v, MotionEvent event) {
    int action = event.getActionMasked();
    int index = event.getActionIndex();
    System.out.println("The finger # " + index + " is " + getAction(action));
    returntrue;
}

publicstatic String getAction(int action) {
    switch (action) {
        case MotionEvent.ACTION_DOWN: return"Down";
        case MotionEvent.ACTION_MOVE: return"Move";
        case MotionEvent.ACTION_POINTER_DOWN: return"Pointer Down";
        case MotionEvent.ACTION_UP: return"Up";
        case MotionEvent.ACTION_POINTER_UP: return"Pointer Up";
        case MotionEvent.ACTION_OUTSIDE: return"Outside";
        case MotionEvent.ACTION_CANCEL: return"Cancel";
        default: return"Unknown";
    }
}
