How to make route drawing more efficient?

Question

This is the code I\'m using to draw route. When i have 1000 of points, route severely slows ui. Maybe someone could provide a code snippet or a link which explains how to do

Answer 1

Best way to increase speed of drawing is reducing number of point the path includes. Probably they are not necessary - lot of them just lays between previous and next, so you can filter them by:

minimal distance from previous point (easy way)

minimal bearing change (a bit harder, although Location class and it's method bearingTo() should help.
