What is the best method for parallax effect when developing an application on the android platform?

Question

Android

I decided to write a simple application for the android platform using the parallax effect, I did it through the sensorManager, everything works, only the picture does not move smoothly at all, and I only need to use the accelerometer for the platform version over 4.1 android. My code is almost completely copied from this article, tell me how to make a smooth parallax effect using only the accelerometer (only the X&Y axes are possible)?
