I have no idea what these bars represent, but still I want to make them in my app on Android platform.
I want that the bars to change on a sound or in my case a recorded sample play.

take a look at this: https://github.com/felixpalmer/android-visualizer/tree/4054f8b6e2153b07c5af275372b9609d1019727a. this is a project with line, circle, and bar visualizers

and btw google beforehand.

The moving bars are called a graphical equaliser. I think this media API sample uses one.
