What is Chromecast? HDMI dongle $35 Smart TV Cast content from your device to your TV

DO I NEED A CHROMECAST TO SEND CONTENT TO MY TV?

Slide 9

Slide 9 text

NO, BUT…

Cast-Ready devices Chromecast Android TV Cast for audio

Slide 11

Slide 11 text

ARCHITECTURE

Slide 12

Slide 12 text

How does it work? Two devices are involved in the process: SENDER: device used for discovery and media control RECEIVER: device used for streaming media (Cast- ready device)

Slide 13

Slide 13 text

Sender Will discover Cast-ready device (same Wiﬁ network or guest access) Will discover media content and tell the Cast-ready device what to play Will behave as a remote control once the Cast-ready device is streaming content

Slide 14

Slide 14 text

IT WILL BE OUR “MOBILE” APP

Slide 15

Slide 15 text

Receiver Will stream media content that the sender tells it to reproduce Can display informative content while in “idle” mode

Slide 16

Slide 16 text

IT WILL BE AN “HTML5” WEBSITE DISPLAYED ON OUR TV CONTROLLED BY OUR “SENDER” APP

Slide 17

Slide 17 text

No content

Slide 18

Slide 18 text

Step by step - Connection (1/3) 1) Receiver advertises itself in the “same network” 2) Sender will discover receiver and will give the option to establish connection with the receiver 3) If user decides to connect, a web socket will be opened between sender and receiver

Slide 19

Slide 19 text

Step by step - Media discovery (2/3) 1) Receiver will fetch its ﬁrst HTML5 screen (Splash Screen) 2) User will select media to play in the sender app, and the sender app will send the URL that the receiver should play

Slide 20

Slide 20 text

Step by step - Streaming content (3/3) 1) Media is downloaded and streamed by the receiver 2) HTML5 receiver app receives media request and starts playing the content

Slide 21

Slide 21 text

WAIT WAIT WAIT!!!

Slide 22

Slide 22 text

DO I HAVE TO WRITE TWO DIFFERENT APPS?

Slide 23

Slide 23 text

WITH TWO DIFFERENT LANGUAGES?

Slide 24

Slide 24 text

FOR TWO DIFFERENT DEVICES?

Slide 25

Slide 25 text

YES!

Slide 26

Slide 26 text

AND YOU WILL HAVE TO DESIGN ALSO FOR TWO DIFFERENT DEVICES…

Slide 27

Slide 27 text

…THAT HAVE NOTHING IN COMMON!

Slide 28

Slide 28 text

No content

Slide 29

Slide 29 text

… BUT GOOGLE WILL PROVIDE SOME “MAGIC” TOOL TO MAKE THE DEVELOPMENT PROCESS EASIER, RIGHT?

Slide 30

Slide 30 text

THE ANSWER IS…

Slide 31

Slide 31 text

DEPENDS

Slide 32

Slide 32 text

Google Cast SDK For sender apps: Full set of APIs for Android (Java), iOS (Objective-C & Swift) and Chrome (Javascript) For receiver apps: HTML5/Javascript APIs

Slide 33

Slide 33 text

THE PROBLEM IS…

Slide 34

Slide 34 text

YOUR APP IS TRYING TO CONQUER THE LIVING ROOM, SO USERS DON’T WANT TO DEAL WITH PROBLEMS, BUGS, CRASHES OR BAD UX

Slide 35

Slide 35 text

YOUR CHROMECAST APP MUST BE…

Slide 36

Slide 36 text

EASY TO USE

Slide 37

Slide 37 text

FAST

Slide 38

Slide 38 text

“AVAILABLE EVERYWHERE”

Slide 39

Slide 39 text

THIS IS NOT EASY TO DO

Slide 40

Slide 40 text

SO YES, GOOGLE HAS SOME “MAGIC TOOLS”

Slide 41

Slide 41 text

THAT ARE ONLY VALID FOR SOME SCENARIOS

Slide 42

Slide 42 text

LUCKILY FOR US…

Slide 43

Slide 43 text

IT WILL COVER MOST OF THE SCENARIOS!

Slide 48 text

Google Cast UX Guidelines - Key Ideas Your app is the remote It’s a shared experience It’s cross platform

Slide 49

Slide 49 text

INTRODUCE CAST THIS IS A ONE-TIME INTRODUCTION SCREEN, SO USERS CAN LEARN HOW TO USE CHROMECAST CAST ICON MUST VISIBLE FROM EVERY SCREEN CAST ICON LOCATION MUST CONSISTENT ACROSS THE APP PREFERRED LOCATION: RIGHT CORNER OF THE NAVIGATION BAR

Slide 50

Slide 50 text

SENDER DISCONNECTED RECEIVER SHOWS HOME SCREEN

Slide 51

Slide 51 text

Cast Button - States UNAVAILABLE: while receivers are not available, cast button doesn’t appear DISCONNECTED: the cast button appears if receivers are available CONNECTING: while the cast receiver is connecting, the cast button animates the waves CONNECTED: the cast button appears with a ﬁlled frame shape

Slide 52

SENDER PLAYS CONTENT - IT BEHAVES AS A REMOTE CONTROL RECEIVER IS PLAYING CONTENT

Slide 72

Slide 72 text

LOCK SCREEN CONTROLS YOUR DEVICE NOW IS A TV REMOTE CONTROL, SO DON’T MAKE YOUR USERS WASTE THEIR TIME

Slide 73

Slide 73 text

… AND DON’T FORGET VOLUME CONTROLS

Slide 74

Slide 74 text

WHAT IF WE LOSE CONNECTION WITH THE RECEIVER? WIFI DISCONNECTION BATTERY DIES APP PROCESS STOPPED

Slide 75

Slide 75 text

YOU SHOULD AUTO-RECONNECT

Slide 76

Slide 76 text

DISCONNECTING

Slide 77

Slide 77 text

ONLY DISCONNECT THE CAST WHEN THE LAST USER DISCONNECTS!

CAST COMPANION LIBRARY THE MAGIG TOOL DEVELOPED BY GOOGLE

Slide 85

Slide 85 text

Cast Companion Library Wrapper around Cast SDK APIs Makes SUPER EASY to develop what’s on the UX guidelines Open source Available on Github: https://github.com/googlecast/CastCompanionLibrary-android

Slide 86

Slide 86 text

LET’S TALK ABOUT CODE!

Slide 87

Slide 87 text

… but ﬁrst Developers must register a test device in the Cast Developer Console https://cast.google.com/publish/#/overview Developer fees: $5

Slide 88

Slide 88 text

Google Cast Developer Console Need to provide app info: package name Register your receiver Marketing details Get your CHROMECAST_APP_ID

Slide 91 text

Assumptions We already have an app with screens in place: Results screen with a list of movies with multiple frames for Popular movies, Most rated,… A details screen listing information about the selected movie A search screen We will have to check if Google Play Services are available

Slide 92

Slide 92 text

Architecture We will build a BaseChromecastActivity, and all the activities in our app will inherit from it Will only contain Cast related code ActionBarActivity BaseChromecastActivity Rest of activities of the app

Slide 93

Slide 93 text

Our goals are… 1. Add cast icon 2. Introduce cast to ﬁrst time users 3. Connect to a Cast-ready device 4. Cast content 5. Add a mini controller in our app 6. Add a sticky notiﬁcation with media controls 7. Add a lock screen with media controls 8. Auto-reconnect when connection is lost

Slide 94

Slide 94 text

KEY CONCEPTS

Slide 95

Slide 95 text

CastManager It is the brain of the Cast functionality. It will update the NotiﬁcationService and the MiniController accordingly. BaseCastManager: abstract class that handles most of connectivity issues that transcends the lifecycle of individual activities. VideoCastManager: designed for video-centric apps

Slide 96

Slide 96 text

HOW DO WE USE THE VIDEOCASTMANAGER?

Slide 97

Slide 97 text

VideoCastManager public class WoodyApplication extends Application { @Override public void onCreate() { super.onCreate(); videoCastManager = VideoCastManager.initialize(getApplicationContext(), Constants.CHROMECAST_APP_ID, null, null); videoCastManager.enableFeatures(VideoCastManager.FEATURE_NOTIFICATION | VideoCastManager.FEATURE_LOCKSCREEN | VideoCastManager.FEATURE_WIFI_RECONNECT | VideoCastManager.FEATURE_CAPTIONS_PREFERENCE | VideoCastManager.FEATURE_DEBUGGING); } }
