67This is an example of keeping track of individual touches across multiple
68[MotionEvent][1]s.
69
70This sample uses a custom View (`TouchDisplayView`) that responds to
71touch events and draws a colored circle for each touch point. The view holds
72data related to a touch pointer, including its current position, pressure,
73and its past touch history.
74
75The View draws graphics based on data associated with each touch event to a
76canvas. A large circle indicates the current position of a touch, while smaller
77trailing circles represent previous positions for that touch.
78The size of the large circle is scaled depending on the pressure of the user's
79touch.
