In IO14 Google's design team declared that they'll be using these icons through out the Google be it desktop or android. They'll be releasing these in coming summer. But me being impatient I created them myself (I'm sure there will be more than this but whatever I could see in IO14, I created them). Both Illustrator and Sketch files are available to download for free. So share it, like it and enjoy it!
