Material Design

Universal platform design that functions across Android Wear, Android

TV, Android Auto, and all of Google’s apps and services

Its all about everything animation, but flat at the same time

Elevation value to any UI surface to get 3D effects by virtual light

sources and real time shadows

Android RunTime (ART)

Running twice as fast as the Dalvik runtime

Work with ARM, x86 and MIPS platforms

64-bit compatible


ART Architecture

Fully compatible with Dalvik’s existing byte-code format (“dex”)

Instead of being a Just-in-Time (JIT) compiler, it now compiles app code

Ahead-of-Time (AOT)


Battery life (Project Volta)

Project Volta is a Project that picks an area of battery weakness and

focuses on tuning the whole OS to fix it

Waking a device up for one second burns two minutes of standby time

New "JobScheduler" API that allows the OS to batch up un-important

app requests like database cleanup and log uploading.

OS will not wake the device up for a network task when there is no

network connectivity

"Battery Historian" tool visualize power events over time and

understand how your app is using battery

Faster compilation of apps using ART virtual machine

New mode allowing the CPU clock speed to be reduced, refresh rate to

be lowered and data to be turned off


Ars Technica's Battery Test

Conducted test with Nexus 5 running the Android L Developer Preview

Two extra hours of battery life in comparison to the previous Android OS

4.4 KitKat

36% more battery life while running Android L Developer Preview


Security

15% of Android users use a PIN or pattern lock

Android is being used regularly on over 1 billion phones

Average user checking their handset over 100 times a day

It can be time consuming and often frustrating if you press or swipe

incorrectly

"Personal Unlocking" - enables the device to determine if it's in a

trusted environment

Universal data controls allowing users to better see what data is shared

with who, under one roof


Multitasking and Recent App

The multitasking menu has been refreshed, complete with a 3D-like

stacked card setup for Apps as well as Chrome browser.

Recent apps are shown with more content displayed, in a much larger

size


Notifications

The notifications by pulling down the bar is replaced with more front and

center of lock screen.

Bringing down a 'Heads up' notification without disruption in much the

same way as iOS

Prioritize the notifications based on your habits


Other Features

Interlinked apps - allows users to search through apps directly from the

search bar, whether it be a restaurant in the OpenTable app or a friend's

page via Facebook

Improved Graphics - GPUs have evolved, so the mobile gaming

industry graphics boost

Multi networking - will help apps switch seamlessly between networks

without interrupting the user flow and interaction within an app

Bluetooth - will feature more peripheral device support, necessary for

TV and Android Wear devices

Android Auto - This is a bit like Apple's CarPlay. it's an in-car system

that runs off your Android phone
