Conheça o caminho das pedras para desenvolver Wearable Apps, TV Apps e para auto. Desmistificando o Design Guide e as APIs.

1. Android Evolved
Android, Wear, Android Auto, And Android TV

Targettrust. Developer for 15 years with background in e-commerce
projects and real estate, since 2009 with focused interests for the
development of mobile and MEAP and applications interfaces.

4. 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.

5. We do not
"ENTERED"
on the internet
we
"live"
online

6. 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.

7. The most popular Google Play Store categories
by September are those dedicated to lifestyle,
entertainment, education, business and
personalization.

8. 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%).

11. 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

12. 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.

13. 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.

14. Create interfaces for
watches is totally different
from creating interfaces
for smartphones and
tablets.

15. 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.

16. 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.

17. 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.

18. Simple interactions
Interaction is all through gestures and voice
commands to be as simple and practical as
possible.

19. 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

20. Apis not supported

Watch Urbane - LG G Watch R

Watch

22. 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.

23. 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.

25. 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.

26. 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.

28. Interaction - Cursor

29. Interaction - Dpad

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

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

34. 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.

35. 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.

36. 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.

37. 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">

40. Noteworthy Bits
Limitations
One way communication
May not be the fastest (i.e. may not be suitable for games)
Discovery handled by the app: Google TV Remote[1] (can use
JmDNS)
Pairing & Auth: Pairing Protocol Reference Implementation[2]
Sending Events: Anymote Protocol Reference Implementation[3]
Pairing and Anymote Protocols user Protocol Buffers[4] (lite)

42. 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.
