26  * This is illustrated by a View ({@link TouchDisplayView}) that responds to
27  * touch events and draws coloured circles for each pointer, stores the last
28  * positions of this pointer and draws them. This example shows the relationship
29  * between MotionEvent indices, pointer identifiers and actions.
