How to make motion blur in android canvas?

Question

Android

I am writing a game for Android. This is a 2D racing game with a side view, everything is drawn on canvas, as the graphics are simple. At low speeds, everything is fine, but when the speed grows to about 100 km / h, it all looks ugly. Especially the background, which is simply impossible to look at. I want to add realism through motion blur. Tell me, please, how to do this, at least some kind of blur? Preferably specifically on canvas, so as not to rewrite polygames

Answer 1

We made a second layer, painted with a blur on the back of the road, and gradually changed the alpha from 0 to 1 as the speed increased.
