Android Lollipop

Android Lollipop (codenamed Android L during development) is the fifth major version of the Android mobile operating system developed by Google and the 12th version of Android, spanning versions between 5.0 and 5.1.1. Unveiled on June 25, 2014, at the Google I/O 2014 conference, it became available through official over-the-air (OTA) updates on November 12, 2014, for select devices that run distributions of Android serviced by Google (such as Nexus and Google Play edition devices). Its source code was made available on November 3, 2014. The first phone with Android Lollipop was the Nexus 6. One of the most prominent changes in the Lollipop release is a redesigned user interface built around a design language known as Material Design, designed to retain a paper-like feel. Other changes include improvements to notifications, which can be accessed from the lock screen and displayed within applications as top-of-screen banners. Google also made internal changes to the platform, with the Android Runtime (ART) officially replacing Dalvik for improved application performance, and with changes intended to improve and optimize battery usage. The Roboto font, originally designed for Android Ice Cream Sandwich, was redesigned in line with Material Design. As of June 2026, 2.02% of Android devices run Android Lollipop, making it the 10th most widely used version of Android. Google Play Services support for Lollipop ended in July 2024.
