Android "Froyo" is a codename of the Android mobile operating system developed by Google, spanning versions between 2.2 and 2.2.3.[1] Those versions are no longer supported. It was unveiled on May 20, 2010, during the Google I/O 2010 conference.

One of the most prominent changes in the Froyo release was USB tethering and Wi-Fi hotspot functionality.[2] Other changes include support for the Android Cloud to Device Messaging (C2DM) service, enabling push notifications, Additional application speed improvements, implemented through JIT compilation[3] and displayed within applications as top-of-the-screen banners.

As of January 9, 2016 statistics issued by Google indicate that less than 0.1% of all Android devices accessing Google Play run Froyo, effectively meaning that this version is no longer in use.[4]
