Android Lollipop

Abstract is: 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 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, which was made to retain a paper-like feel to the interface. Other changes include improvements to the notifications, which can be accessed from the lockscreen and displayed within applications as top-of-the-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. As of October 2022, 0.41% of Android devices run Lollipop 5.0 (API 21) and 2.79% run Lollipop 5.1 (API 22) combined. However, this figure is misleading, as on tablets Android 5.1 is much more popular than it is on phones, being ranked 3rd of all Android versions at 8.98% when counting Android 7.0 and 7.1 Nougat separately. When market shares for versions 7.0 and 7.1 are combined, Nougat is more popular than Lollipop, at 11.04% on tablets, making Lollipop the fourth most popular version.
