- 60. Step 1: Discovery Hello? My IP address is xxx.xxx.x.x, I offer service _anymote._tcp on port xxxx mDNS Broadcasts
- 61. Step 1: Discovery Oh you have the _anymote._tcp service, you must be a Google TV
- 62. Step 2: Pairing Hey, can I connect to you? Pairing Request Yeah sure :) Pairing Ack Cool, well I can deal with hexadecimal passwords & ... Challenges it can deal with Well I can give you these challenges and you need to give me back this ... Challenges it can give & expected response
- 63. Step 2: Pairing I challenge you!! Mwuahaha Challenge Easy. “1234” Secret You got it, heres the top secret password “Awesome sauce” Secret Ack
- 64. Step 3: Anymote The fun part
- 65. But this wasn’tfriendly :(
- 66. Anymote Library Makes Anymoteeasy 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
- 67. Impl. ClientListener Interface Java public class YourActivity extends Activity implements AnymoteClientService.ClientListener { private AnymoteSender anymoteSender; @Override public void onConnected(AnymoteSender anymoteSender) { this.anymoteSender = anymoteSender; // Save for sending messages } @Override public void onDisconnected() { ... } @Override public void onConnectionError() { ... } ... }
- 68. Impl. a ServiceConnection Java private 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 notifications anymoteService = null; } };
- 69. Bind to AnymoteClientService Java @Override public void onCreate(Bundle savedInstanceState) { ... Intent intent = new Intent(this, AnymoteClientService.class); bindService(intent, serviceConnection, Context.BIND_AUTO_CREATE); }
- 70. Want a Trackpad? Turn any View into a trackpad Java new TouchHandler(someView, Mode.POINTER, anymoteSender); Available Modes: - POINTER - SCROLL_HORIZONTALLY - SCROLL_VERTICALLY -ZOOM_VERTICAL
- 71. Send Key Events You can send key events to take control of Google TV Java someButton.setOnClickListener(new OnClickListener() { public void onClick(View v) { anymoteSender.sendKeyPress(KeyEvent.KEYCODE_DPAD_CENTER); } }); 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/
- 72. Send Intents Possibly the most powerful feature is the ability to send intents Java 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); Default use case is to open a companion application on the TV, but you can do more...
- 73. Control All theApps...* com.yourapp.ACTION_SHOW_FOO com.randomapp.ACTION_SHOW_BAR * with open intents

- 84. Please don’t dothis
- 85.
- 86. Publishing No-No’s - Never do this XML <activity android:screenOrientation="portrait"> - This will get filtered out XML <uses-feature android:name="android.hardware.screen.portrait" android:required=”true” /> - Use this and pain will follow XML setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_POTRAIT);
- 87. Publishing Checklist - Tell Play that you don’t need touch events XML <uses-feature android:name="android.hardware.touchscreen" android:required= “false” /> - Do you need to target Google TV only? XML <uses-feature android:name="com.google.android.tv" android:required= “true” /> - Lastly . . . Tell us about it
