LeftNavBar

XML

To Use It?

private LeftNavBar mLeftNavBar;

...

private LeftNavBar getLeftNavBar() { if (mLeftNavBar == null) {    mLeftNavBar = new LeftNavBar(this);    }    return mLeftNavBar;}

- Use the LeftNavBar like so...

- Then treat it like an ActionBar (it’s the same API)

So Much Space

• Traditionally designed consumption not interaction

• Far away = lower information density

• Ironically, not so good for reading a lot of text

• Big Sound: Great for video, and listening to music

• Different than phones: personal, location, size, touch

• Not just a big Tablet => more like a PHONE

Big, but small

Anymote Protocol

Step 1: Discovery

mDNS Broadcasts

Hello? My IP address is xxx.xxx.x.x, I offer

service _anymote._tcp on port xxxx

Step 1: Discovery

Oh you have the _anymote._tcp service,

you must be a Google TV

Step 2: PairingHey, can I connect to you?

Pairing Request

Yeah sure :)Pairing Ack

Cool, well I can deal with hexadecimal passwords & ...

Well I can give you these challenges and you need to give me back this ...

Challenges it can deal with

Challenges it can give & expected response

Step 2: Pairing

Easy. “1234”

Secret

I challenge you!! MwuahahaChallenge

You got it, heres the top secret password “Awesome sauce”

Secret Ack

Step 3: Anymote

The fun part

But this wasn’t friendly :(

Anymote LibraryMakes Anymote easy to use

An Android Library project which simplifies finding, pairing and sending events to Google TV using the Anymote Protocol

1.Implement the AnymoteClientService.ClientListener interface (3 methods)

2.Implement a ServiceConnection to attach your ClientListener to the AnymoteClientService

3.Bind to the AnymoteClientService to initiate the pairing process

4.Use the AnymoteSender to send messages to Google TV using the Anymote protocol

Impl. ClientListener Interfacepublic class YourActivity extends Activity implements AnymoteClientService.ClientListener {

private AnymoteSender anymoteSender;

@Overridepublic void onConnected(AnymoteSender anymoteSender) {

this.anymoteSender = anymoteSender; // Save for sending messages}

@Overridepublic void onDisconnected() { ... }

@Overridepublic void onConnectionError() { ... }

...

}

Java

Impl. a ServiceConnectionprivate AnymoteClientService anymoteService;

private ServiceConnection serviceConnection = new ServiceConnection() {

public void onServiceConnected(ComponentName name, IBinder service) {anymoteService = ((AnymoteClientService.AnymoteClientServiceBinder) service).getService();anymoteService.attachClientListener(YourActivity.this); // YourActivity is a ClientListener

// TODO: Check if the service already has a AnymoteSender}

public void onServiceDisconnected(ComponentName name) {anymoteService.detachClientListener(YourActivity.this); // Stop receiving notificationsanymoteService = null;

}

};

Java

Bind to AnymoteClientService@Overridepublic void onCreate(Bundle savedInstanceState) {

...

Intent intent = new Intent(this, AnymoteClientService.class);bindService(intent, serviceConnection, Context.BIND_AUTO_CREATE);

}

Java

Want a Trackpad?Turn any View into a trackpad

Available Modes:

- POINTER- SCROLL_HORIZONTALLY- SCROLL_VERTICALLY-ZOOM_VERTICAL

new TouchHandler(someView, Mode.POINTER, anymoteSender);Java

Send Key EventsYou can send key events to take control of Google TV

For a full list of available key codes download the anymote-protocol and then look at ./proto/keycodes.proto

http://code.google.com/p/anymote-protocol/

someButton.setOnClickListener(new OnClickListener() {public void onClick(View v) {

anymoteSender.sendKeyPress(KeyEvent.KEYCODE_DPAD_CENTER);}

});

Java

Send Intents

Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(“http://www.google.com”));anymoteSender.sendIntent(intent);

Java

Intent intent = new Intent(“com.example.yourapp.VIEW_ACTION”);anymoteSender.sendIntent(intent);

Java

Possibly the most powerful feature is the ability to send intents

Default use case is to open a companion application on the TV, but you can do more...

Control All the Apps...*

* with open intents

com.yourapp.ACTION_SHOW_FOO

com.randomapp.ACTION_SHOW_BAR

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]

Please don’t do this

Publishing Time

Publishing No-No’s- Never do this

- This will get filtered out

- Use this and pain will follow

<activity android:screenOrientation="portrait"> XML

<uses-featureandroid:name="android.hardware.screen.portrait" android:required=”true” />

XML

setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_POTRAIT); XML

Publishing Checklist- Tell Play that you don’t need touch events

- Do you need to target Google TV only?

- Lastly . . . Tell us about it

<uses-feature android:name="android.hardware.touchscreen"android:required= “false” />

XML

<uses-feature android:name="com.google.android.tv"android:required= “true” />
