44. Fields - MainActivity.java private MediaRouteButton mMediaRouteButton; private MediaRouter mMediaRouter; private MediaRouteSelector mMediaRouteSelector; private MediaRouter.Callback mMediaRouterCallback; private CastDevice mSelectedDevice; The Router Callbacks. These Callbacks are used to Notify the Application on Select and Deselction of an Device Route and enables us to react to these events e.g by printing the Connected Device to the User.

45. Fields - MainActivity.java private MediaRouteButton mMediaRouteButton; private MediaRouter mMediaRouter; private MediaRouteSelector mMediaRouteSelector; private MediaRouter.Callback mMediaRouterCallback; private CastDevice mSelectedDevice; The Cast Device we are Connected to. It contains Informations like Device Name, Model, Capabilities, etc.

Initializing - MainActivity.java @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar); setSupportActionBar(toolbar); mConnectionStatus = (TextView) findViewById(R.id.text_connection); mMediaRouteButton = (MediaRouteButton) findViewById(R.id.media_route_button); initCast(); }

50. Initializing - MainActivity.java private void initCast() { // Configure Cast device discovery mMediaRouter = MediaRouter.getInstance(getApplicationContext()); }

51. Initializing - MainActivity.java private void initCast() { // Configure Cast device discovery mMediaRouter = MediaRouter.getInstance(getApplicationContext()); mMediaRouteSelector = new MediaRouteSelector.Builder() .addControlCategory( CastMediaControlIntent.categoryForCast(getResources().getString(R.string.app_id))) .build(); }

52. Initializing - MainActivity.java private void initCast() { // Configure Cast device discovery mMediaRouter = MediaRouter.getInstance(getApplicationContext()); mMediaRouteSelector = new MediaRouteSelector.Builder() .addControlCategory( CastMediaControlIntent.categoryForCast(getResources().getString(R.string.app_id))) .build(); } The Cast Application ID. E.g “794B7BBF” (Cast Sample Helloworld)

53. Initializing - MainActivity.java private void initCast() { // Configure Cast device discovery mMediaRouter = MediaRouter.getInstance(getApplicationContext()); mMediaRouteSelector = new MediaRouteSelector.Builder() .addControlCategory(CastMediaControlIntent.categoryForCast(getResources() .getString(R.string.app_id))) .build(); // Set the MediaRouteButton selector for device discovery. mMediaRouteButton.setRouteSelector(mMediaRouteSelector); }

54. Initializing - MainActivity.java @Override public boolean onCreateOptionsMenu(Menu menu) { // Inflate the menu; this adds items to the action bar if it is present. getMenuInflater().inflate(R.menu.main, menu); MenuItem mediaRouteMenuItem = menu.findItem(R.id.media_route_menu_item); MediaRouteActionProvider mediaRouteActionProvider = (MediaRouteActionProvider) MenuItemCompat .getActionProvider(mediaRouteMenuItem); // Set the MediaRouteActionProvider selector for device discovery. mediaRouteActionProvider.setRouteSelector(mMediaRouteSelector); return true; }

58. Adding Callbacks - MainActivity.java private void initCast() { // Configure Cast device discovery mMediaRouter = MediaRouter.getInstance(getApplicationContext()); mMediaRouteSelector = new MediaRouteSelector.Builder() .addControlCategory(CastMediaControlIntent.categoryForCast(getResources() .getString(R.string.app_id))) .build(); // Set the MediaRouteButton selector for device discovery. mMediaRouteButton.setRouteSelector(mMediaRouteSelector); mMediaRouterCallback = new MyMediaRouterCallback(); }

59. Adding Callbacks - MainActivity.java private class MyMediaRouterCallback extends MediaRouter.Callback { @Override public void onRouteSelected(MediaRouter router, MediaRouter.RouteInfo info) { // Handle the user route selection. mSelectedDevice = CastDevice.getFromBundle(info.getExtras()); mConnectionStatus.setText("Connected to: " + mSelectedDevice.getFriendlyName()); } @Override public void onRouteUnselected(MediaRouter router, MediaRouter.RouteInfo info) { mSelectedDevice = null; mConnectionStatus.setText("Not Connected"); } }

61. Adding Callbacks - MainActivity.java private class MyMediaRouterCallback extends MediaRouter.Callback { @Override public void onRouteSelected(MediaRouter router, MediaRouter.RouteInfo info) { // Handle the user route selection. mSelectedDevice = CastDevice.getFromBundle(info.getExtras()); mConnectionStatus.setText("Connected to: " + mSelectedDevice.getFriendlyName()); } @Override public void onRouteUnselected(MediaRouter router, MediaRouter.RouteInfo info) { mSelectedDevice = null; mConnectionStatus.setText("Not Connected"); } } Called after we Selected an Cast Device we want to Connect with. This does not mean we are Connected to the Cast Application yet!

62. Adding Callbacks - MainActivity.java private class MyMediaRouterCallback extends MediaRouter.Callback { @Override public void onRouteSelected(MediaRouter router, MediaRouter.RouteInfo info) { // Handle the user route selection. mSelectedDevice = CastDevice.getFromBundle(info.getExtras()); mConnectionStatus.setText("Connected to: " + mSelectedDevice.getFriendlyName()); } @Override public void onRouteUnselected(MediaRouter router, MediaRouter.RouteInfo info) { mSelectedDevice = null; mConnectionStatus.setText("Not Connected"); } } Called after we Decided to Disconnect from an Cast Device. This does not mean we are Disconnected from the Application yet!

66. Starting Discovery - MainActivity.java @Override protected void onStart() { super.onStart(); // Start media router discovery mMediaRouter.addCallback(mMediaRouteSelector, mMediaRouterCallback, MediaRouter.CALLBACK_FLAG_REQUEST_DISCOVERY); } @Override protected void onStop() { // End media router discovery mMediaRouter.removeCallback(mMediaRouterCallback); super.onStop(); }

Sending Messages - MainActivity.java class HelloWorldChannel implements Cast.MessageReceivedCallback { public String getNamespace() { return getString(R.string.namespace); } @Override public void onMessageReceived(CastDevice castDevice, String namespace, String message) { } } Our Custom Namespace. This is defined in our reciever app. e.g. urn:x-cast:com.google.cast.sample.helloworld

100. Sending Messages - MainActivity.java class HelloWorldChannel implements Cast.MessageReceivedCallback { public String getNamespace() { return getString(R.string.namespace); } @Override public void onMessageReceived(CastDevice castDevice, String namespace, String message) { } } This gets Triggered when the Reciever Sends Data To our Client. e.g. Updated Scores on Games

101. Sending Messages - MainActivity.java // Launch the receiver app Cast.CastApi.launchApplication(mApiClient, getString(R.string.app_id), false) …. // Create the custom message // channel mHelloWorldChannel = new HelloWorldChannel(); try { Cast.CastApi.setMessageReceivedCallbacks( mApiClient, mHelloWorldChannel.getNamespace(), mHelloWorldChannel); } catch (IOException e) { Log.e(TAG, "Exception while creating channel", e); }

105. Sending Messages - MainActivity.java private void sendMessage(String message) { if (mApiClient != null && mHelloWorldChannel != null) { try { Cast.CastApi.sendMessage(mApiClient, mHelloWorldChannel.getNamespace(), message).setResultCallback( new ResultCallback<Status>() { @Override public void onResult(Status result) { if (!result.isSuccess()) { Log.e(TAG, "Sending message failed"); } } }); } catch (Exception e) { Log.e(TAG, "Exception while sending message", e); } }

109. Sending Messages - MainActivity.java mSendButton = (Button) findViewById(R.id.button_send); mSendButton.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { sendMessage(mTextInput.getText().toString()); } });

110. Sending Messages - MainActivity.java mSendButton = (Button) findViewById(R.id.button_send); mSendButton.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { sendMessage(mTextInput.getText().toString()); } });
