Hi, I am trying to render a customized view which draws points on the canvas whenever they arrive from a remote device. Whenever a new value is obtained - it gets passed into my customized view which draws it on the canvas - ( The canvas should still show my previous points). Now whenever i call invalidate() in my onDraw() method it clears all my previous points. The application is supposed to work with a stream of data and as such there are large number of points which are generated and as such we dont want to store the points in an array and reproduce them on the canvas- rather just get the new point draw it on the canvas (the previous points should stay). Does anyone know how to go about keeping all previous canvas objects intact while performing invalidate?
