Android L

Posted by VariyaSoft on 14-08-2014 in Android

Android L is an upcoming release of the Android mobile operating system developed by Google. Unveiled on 25 June 2014, and released in a beta the next day for selected Google Nexus devices, it is expected to be released in late 2014.

The most prominent changes to L include a redesigned user interface built around a responsive design language referred to as "material design", and improvements to the notification system which allow them to be accessed from the lock screen, and displayed within other apps as banners across the top of the screen. Internal changes were also made to the platform, with the Android Runtime (ART) officially replacing Dalvik for improved application performance, and changes intended to improve and optimize battery usage.


  • Android L introduces a refreshed notification system. Individual notifications are now displayed on cards to adhere to the material design language, and batches of notifications can be grouped by the app that produced them. Notifications are now displayed on the lock screen as cards, and "heads up" notifications can also be displayed as large banners across the top of the screen, along with their respective action buttons. A do-not-disturb feature is also added for notifications.
  • Android L also contains major new platform features for developers; over 5,000 new APIs were added for use by apps, and the Dalvik virtual machine was officially replaced by Android Runtime (ART), a new environment introduced as a technology preview in KitKat.
  • Android L also aims to improve battery consumption through a series of optimizations known as "Project Volta". Among its changes is a new battery saver mode, job scheduling APIs which can restrict certain tasks to only occur over Wi-Fi, and batching of tasks to reduce the overall amount of time that internal radios are active. This feature called "Battry Historian".
  • A number of system-level, enterprise-oriented features were also introduced under the banner "Android for Work"
