i am making an music player in android, i have a list with album art and all the song information in it. now when i play a certain song i want the album art to change and instead i want a 3 bar visualizer there similar to google music player, equalizer+ music player. I dont seem to understand how to do a 3 bar visualizer, and i am not sure wether those 3 bars are visualizers. any suggestion how to go about it would help, i am attaching two pics of google music before the song is played and during the song is playing, notice the 3 bars in the left.image before playing

Image after playing

There is an Android Visualizer library available that has a visualization mode with frequency distributions (the 'bar visualization'):
enter image description heregif

There are various other visualization modes available, the source code of the Bar visualizer is available here and can be customized to fit your needs.

A demo of how to use the library with the MediaPlayer is included in the project. https://github.com/felixpalmer/android-visualizer
