Do I need to copyright Google Material icons?

Question

Android

Good afternoon, the application was blocked for using other people's icons.
I decided to change all the icons to these - https://design.google.com/icons/
Do I need to put any links to licenses/copyrights in the application to use them?

Answer 1

It says right there on the main page:

We'd love attribution in your app's "about" screen, but it's not required.
