1. Material design
Android 5.0
brings Material design to Android and
gives you an expanded UI toolkit for integrating the new design patterns easily
in your apps.
New 3D views
let you set a z-level to raise elements off of the view hierarchy and cast realtime
shadows, even as they move.
Built-in activity
transitions take the user seamlessly from one state to another with
beautiful, animated motion. The material theme adds transitions for your
activities, including the ability to use shared visual elements across
activities.

Ripple
animations are available for buttons, checkboxes, and other touch controls in
your app.
You can also
define vector drawables in XML and animate them in a variety of ways. Vector
drawables scale without losing definition, so they are perfect for single-color
in-app icons.
A new
system-managed processing thread called RenderThread keeps animations
smooth even when there are delays in the main UI thread.
2.Performance focus
Android 5.0
provides a faster, smoother and more powerful computing experience.
Android now
runs exclusively on the new ART runtime, built from the ground up to
support a mix of ahead-of-time (AOT), just-in-time (JIT), and interpreted code.
It’s supported on ARM, x86, and MIPS architectures and is fully 64-bit
compatible.
ART improves
app performance and responsiveness. Efficient garbage collection reduces the
number and duration of pauses for GC events, which fit comfortably within the
v-sync window so your app doesn’t skip frames. ART also dynamically moves
memory to optimize performance for foreground uses.
Android 5.0
introduces platform support for 64-bit architectures—used by the Nexus
9's NVIDIA Tegra K1. Optimizations provide larger address space and improved
performance for certain compute workloads. Apps written in the Java language
run as 64-bit apps automatically—no modifications are needed. If your app uses
native code, we’ve extended the NDK to support new ABIs for ARM v8, and x86-64,
and MIPS-64.
Continuing the
focus on smoother performance, Android 5.0 offers improved A/V sync. The audio
and graphics pipelines have been instrumented for more accurate timestamps,
enabling video apps and games to display smooth synchronized content.
3.Notifications
Notifications
in Android 5.0 are more visible, accessible, and configurable.
Varying
notification details may appear on the lock screen if desired by the
user. Users may elect to allow none, some, or all notification content to be
shown on a secure lock screen.
Key
notification alerts such as incoming calls appear in a heads-up notification—a
small floating window that allows the user to respond or dismiss without
leaving the current app.
You can now add
new metadata to notifications to collect associated contacts (for
ranking), category, and priority.
A new media notification template provides
consistent media controls for notifications with up to 6 action buttons,
including custom controls such as "thumbs up"—no more need for
RemoteViews!
4.Your apps on the big screen
Android TV provides a complete TV platform for your app's
big screen experience. Android TV is centered around a simplified home screen
experience that allows users to discover content easily, with personalized
recommendations and voice search.
With Android TV you can now create big, bold
experiences for your app or game content and support interactions with game
controllers and other input devices. To help you build cinematic, 10-foot UIs
for television, Android provides a leanback UI framework in the v17
support library.
The Android TV Input Framework (TIF) allows TV
apps to handle video streams from sources such as HDMI inputs, TV tuners, and
IPTV receivers. It also enables live TV search and recommendations via metadata
published by the TV Input and includes an HDMI-CEC Control Service to handle
multiple devices with a single remote.
The TV Input Framework provides access to a wide variety
of live TV input sources and brings them together in a single user interface
for users to browse, view, and enjoy content. Building a TV input service for
your content can help make your content more accessible on TV devices.
5.Document-centric apps
Android 5.0 introduces a redesigned
Overview space (formerly called Resents) that’s more versatile and useful for
multitasking.
New APIs allow you to show separate
activities in your app as individual documents alongside other recent screens.
You can take advantage of concurrent
documents to provide users instant access to more of your content or services.
For example, you might use concurrent documents to represent files in a
productivity app, player matches in a game, or chats in a messaging app.
6.Advanced connectivity
Android 5.0 adds new APIs that allow
apps to perform concurrent operations with Bluetooth Low Energy (BLE),
allowing both scanning (central mode) and advertising (peripheral mode).
New multi-networking features
allow apps to query available networks for available features such as whether
they are Wi-Fi, cellular, metered, or provide certain network features. Then
the app can request a connection and respond to connectivity loss or other
network changes.
NFC APIs now allow apps to
register an NFC application ID (AID) dynamically. They can also set the
preferred card emulation service per active service and create an NDEF record
containing UTF-8 text data.
7.High-performance
graphics
Support for Khronos OpenGL ES 3.1 now
provides games and other apps the highest-performance 2D and 3D graphics
capabilities on supported devices.
OpenGL
ES 3.1 adds compute shaders, stencil textures, accelerated visual effects, high
quality ETC2/EAC texture compression, advanced texture rendering, standardized
texture size and render-buffer formats, and more.
Gameloft's
Rival Knights uses ASTC (Adaptive Scalable Texture Compression) from AEP and
Compute Shaders from ES 3.1 to deliver HDR (High Dynamic Range) Bloom effects
and provide more graphical detail.
Android 5.0
also introduces the Android Extension Pack (AEP), a set of OpenGL ES
extensions that give you access to features like tessellation shaders, geometry
shaders, ASTC texture compression, per-sample interpolation and shading, and
other advanced rendering capabilities. With AEP you can deliver
high-performance graphics across a range of GPUs.
8.More powerful audio
A
new audio-capture design offers low-latency audio input. The new design
includes: a fast capture thread that never blocks except during a read; fast
track capture clients at native sample rate, channel count, and bit depth; and
normal capture clients offer re sampling, up/down channel mix, and up/down bit
depth.
Multichannel audio stream mixing allows professional audio apps to mix up to eight
channels including 5.1 and 7.1 channels.
Apps
can expose their media content and browse media from other apps, then
request playback. Content is exposed through a query able interface and does not
need to reside on the device.
Apps
have finer-grain control over text-to-speech synthesis through voice
profiles that are associated with specific locales, quality and latency rating.
New APIs also improve support for synthesis error checking, network synthesis,
language discovery, and network fallback.
Android now includes support
for standard USB audio peripherals, allowing users to connect USB
headsets, speakers, microphones, or other high performance digital peripherals.
Android 5.0 also adds support for Opus audio codecs.
9.Enhanced camera & video
Android
5.0 introduces all new camera APIs that let you capture raw formats such
as YUV and Bayer RAW, and control parameters such as exposure time, ISO
sensitivity, and frame duration on a per-frame basis. The new
fully-synchronized camera pipeline allows you to capture uncompressed full-resolution
YUV images at 30 FPS on supported devices.
Along
with images, you can also capture metadata like noise models and optical
information from the camera.
Apps
sending video streams over the network can now take advantage of H.265 High
Efficiency Video Coding (HEVC) for optimized encoding and decoding of video
data.
Android
5.0 also adds support for multimedia tunneling to provide the best
experience for ultra-high definition (4K) content and the ability to play
compressed audio and video data together.
