Android 5.0 "Lollipop" is the latest version of
the Android mobile operating system developed
by Google . Unveiled on June 25, 2014 during
Google I/O , it became available as official
over-the-air (OTA) updates on November 12,
2014 for select devices that run distributions
of Android serviced by Google, including Nexus
and Google Play edition devices. Its source
code was made available on November 3, 2014.
One of the most prominent changes in the
Lollipop release is a redesigned user interface
built around a responsive design language
referred to as "material design". Other
changes include improvements to the
notification system which allow notifications
to be accessed from the lockscreen, and to be
displayed within other apps as banners across
the top of the screen. 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, known internally as
Project Volta.
Development
Android 5.0 was first unveiled under the
codename "Android L" on June 25, 2014 during
a keynote presentation at the Google I/O
developers' conference. Alongside Lollipop, the
presentation focused on a number of new
Android-oriented platforms and technologies,
including Android TV , in-car platform Android
Auto , wearable computing platform Android
Wear , and health tracking platform Google Fit .

Part of the presentation was dedicated to a
new cross-platform design language referred
to as "material design". Expanding upon the
"card " motifs first seen in Google Now , it is a
cleaner design with increased use of grid-
based layouts, responsive animations and
transitions, padding, and depth effects such
as lighting and shadows. Designer Matías
Duarte explained that "unlike real paper, our
digital material can expand and reform
intelligently. Material has physical surfaces
and edges. Seams and shadows provide
meaning about what you can touch." The
material design language will not only be used
on Android, but across Google's suite of web
software as well, providing a consistent
experience across all platforms. [5][6][7][8][9]
Features
Android 5.0 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. [6][10] A
do-not-disturb feature is also added for
notifications. The recent apps menu was
redesigned to use a three-dimensional stack of
cards to represent open apps. Individual apps
can also display multiple cards in the recent
menu, rather than only one entry per app; for
example, a web browser can show all of its
open tabs as individual cards. [6][8][11]
Lollipop also contains major new platform
features for developers, with over 5,000 new
APIs added for use by applications. [12][13]
Additionally, the Dalvik virtual machine was
officially replaced by Android Runtime (ART),
which is a new runtime environment that was
introduced as a technology preview in KitKat.
[14] ART is a cross-platform runtime which
supports the x86 , ARM , and MIPS
architectures in both 32-bit and 64-bit
environments. Unlike Dalvik, which uses just-
in-time compilation (JIT), ART compiles apps
upon installation , which are then run
exclusively from the compiled version from
then on. This technique removes the processing
overhead associated with the JIT process,
improving system performance. [15]
Lollipop also aims to improve battery
consumption through a series of optimizations
known as "Project Volta". Among its changes
are 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. The new developer
tool called "Battery Historian" can be used for
tracking battery consumption by apps while in
use. [4][6] The Android Extension Pack APIs
also provide graphics functions such as new
shaders , aiming to provide PC-level graphics
for 3D games on Android devices. [9][16]
A number of system-level, enterprise-oriented
features were also introduced under the
banner "Android for Work": Samsung
contributed its Knox security framework for
segregating personal and work-oriented data
from each other on a device, along with
accompanying APIs for managing the
environment. Devices can also be configured so
that users do not have to unlock their device
with a PIN or pattern if it is within a trusted,
physical location, or is in proximity to a user's
Android Wear device. [11][17] Device encryption
will be enabled by default. [18]
