Android has evolved. Already a mature mobile OS that is one of the two dominant operating systems in a huge and still-growing mobile

market, Android is officially not just for phones and tablets. It’s on your wrist, in your car, and

in your living room.

We do not "ENTERED"

on the internet we

"live" online

Right now, there are 1,362,720 apps in the Google Play Store. More than a million are free,

and only around 200,000 apps are paid.

The most popular Google Play Store categories by September are those dedicated to lifestyle,

entertainment, education, business and personalization.

About the most popular devices, it’s remarkable to note that all the Top 10 Android phones are Samsung models: Samsung Galaxy S3 is the

most used Android phone (6.3% market share), followed by Samsung Galaxy S4 (5.3%).

Suddenly, the smartwatch is evolving. We had an inkling that this would happen when we first caught wind of Android Wear back in March of 2014, and we’re just about to be inundated with Android Wear-based smartwatches from all the usual consumer tech companies, including LG,

Samsung, Motorola, and ASUS

Android Wear is an extension of Android that is a companion to devices running Android 4.3

and higher. It connects to your smartphone and uses a pretty and clear UI to give you a

variety of information such as the time of day, messages, and alerts. You can also see traffic,

send messages, call yourself a cab, and all manner of other uses involving Google Now

and the “OK Google” voice command.

The idea is really to reduce the amount of time you spend pulling out your phone, entering a

password, swiping, and whatnot. Thus, Android Wear devices really are a convenient extension

of your smartphone.

Create interfaces for watches is totally different from creating interfaces

for smartphones and tablets.

Start applications or cards automatically

Users are used to start the applications manually, but wear the cards appear on the screen, showing relevant information at that

time. As a meeting reminder, e-mail message

notification.

Simple Interface, practical and fast

Aka glanceable.They should be practical and lightweight. The less time you take to

understand the meaning of the screen, the better.

Suggestions on demand

The apps are responsive and can react to events to assist the user in moments of

everyday life, such as sending a text message to a contact quickly by voice command.

Simple interactions

Interaction is all through gestures and voice commands to be as simple and practical as

possible.

Creating Wearable App

Apps run directly from the device Access to sensors and GPU

Same basis SDK

No Wear there is a timeout The Download is done by smartphone not for

wear. It offers automatic

Android Auto brings a similar experience to your car. Like Apple and others looking to bake

some more intelligence into our vehicles, Google is partnering with many automakers to

put Android-powered infotainment in the cockpit.

Obviously, the killer application is Google Maps with navigation, but there are other useful

features as well, including viewing notifications, using voice commands, and more. Google expects to have Android Auto

capabilities in cars on dealer lots by the close of the year.

Android TV is the next logical evolution of Chromecast, the intriguing streaming stick that

Google unveiled last year.

It’s a software offering that brings the Android experience to TVs and set-top boxes. “You can use voice search to find a live TV show, a good

flick from Google Play, or a music video on YouTube,” reads a press release.

You can also play Android games with a gamepad, which is a huge selling point for the platform, and like Chromecast, Google Cast

technology is built in. Look for Android TV on a number of products later this year.

Interaction - Dpad

Prerequisites

Update your SDK tools to version 24.0.0 or higher Update your SDK with Android 5.0 (API 21) or higher

Supported Media Formats

It is a best practice to use media encoding profiles that are device-agnostic.

DRM

The Android platform provides an extensible DRM framework that lets applications manage rights-protected content according to the license constraints associated with the content. The DRM framework supports many DRM schemes; which DRM schemes a device supports is up to the device manufacturer.

ExoPlayer

The Android framework provides MediaPlayer as a quick solution for playing media with minimal code, and the MediaCodec and MediaExtractor classes are provided for building custom media players.

Use Layout Themes for TV

Android Themes can provide a basis for layouts in your TV apps. You should use a theme to modify the display of your app activities that are meant to run on a TV device. This section explains which themes you should use.

Use Layout Themes for TV

A support library for TV user interfaces called the v17 leanback library provides a standard theme for TV activities, called Theme.Leanback.

<activity android:name="com.example.android.TvActivity" android:label="@string/app_name" android:theme="@style/Theme.Leanback">

Finally, another important piece of the Android pie is coming for emerging markets with

Android One, an affordable handset that will launch in India this fall for less than $100 with

more countries in line.

We have a great many screens in our lives these days, and Google wants every single one

of them to show you Android.
