Sender app: Os passos para o sucesso...

1. Descoberta de dispositivos

2. Gerenciamento de sessão

3. Transimissão de dados

Sender app: Descoberta de dispositivos

<?xml version="1.0" encoding="utf-8"?><menu xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" >

Descoberta de dispositivos: Media Router Selector

public class MediaRouterPlaybackActivity extends ActionBarActivity { private MediaRouteSelector mSelector;

@Override protected void onCreate(Bundle savedInstanceState) { (...) // Create a route selector for the type of routes your app supports. mSelector = new MediaRouteSelector.Builder() // These are the framework-supported intents .addControlCategory(MediaControlIntent.CATEGORY_LIVE_AUDIO) .addControlCategory(MediaControlIntent.CATEGORY_LIVE_VIDEO) .addControlCategory(MediaControlIntent.CATEGORY_REMOTE_PLAYBACK) .build();

(...) }}

Descoberta de dispositivos: Media Router Selector

public boolean onCreateOptionsMenu(Menu menu) { super.onCreateOptionsMenu(menu);

// Inflate the menu and configure the media router action provider. getMenuInflater().inflate(R.menu.sample_media_router_menu, menu);

// Attach the MediaRouteSelector to the menu item MenuItem mediaRouteMenuItem = menu.findItem(R.id.media_route_menu_item); MediaRouteActionProvider mediaRouteActionProvider = (MediaRouteActionProvider) MenuItemCompat.getActionProvider(mediaRouteMenuItem); mediaRouteActionProvider.setRouteSelector(mSelector);

// Return true to show the menu. return true;}

Gerenciamento de sessão: Media Router Callback

private final MediaRouter.Callback mMediaRouterCallback = new MediaRouter.Callback() {

@Override public void onRouteSelected(MediaRouter router, RouteInfo route) { }

@Override public void onRouteUnselected(MediaRouter router, RouteInfo route) { }

@Override public void onRoutePresentationDisplayChanged(MediaRouter router, RouteInfo route) { }}

public class MediaRouterPlaybackActivity extends ActionBarActivity { protected void onCreate(Bundle savedInstanceState) { mMediaRouter = MediaRouter.getInstance(this); }

public void onStart() { mMediaRouter.addCallback(mSelector, mMediaRouterCallback,

MediaRouter.CALLBACK_FLAG_REQUEST_DISCOVERY); }

public void onStop() { mMediaRouter.removeCallback(mMediaRouterCallback); super.onStop(); }}

Transmissão de dados: Mensagem genérica

Cast.CastApi.sendMessage (com.google.android.gms.common.api.GoogleApiClient, NAMESPACE, message)

.setResultCallback (new ResultCallback<Status>() {

@Overridepublic void onResult(Status result) {

if (!result.isSuccess()) { Log.e(TAG, "Sending message failed"); }}});

Transmissão de dados: Remote playback

protected void onCreate(Bundle savedInstanceState) { Bundle mediaInfo = new Bundle(); mediaInfo.putString(MediaMetadata.KEY_TITLE, "Big Buck Bunny"); mediaInfo.putString(MediaMetadata.KEY_SUBTITLE, "Blender Foundation"); mediaInfo.putString(MediaMetadata.KEY_STUDIO, "Fusce id nisi turpis. Praesent viverra bibendum semper. Donec tristique, orci");

(...)}

Transmissão de dados: Remote playback

public void onRouteSelected(MediaRouter router, RouteInfo route) { mRemotePlaybackClient = new RemotePlaybackClient(this, route); mRemotePlaybackClient.play(Uri.parse("http://meu_video.mp4"), "video/mp4", mediaInfo, 0, null, new ItemActionCallback() {

@Override public void onResult(Bundle data, String sessionId, MediaSessionStatus sessionStatus, String itemId, MediaItemStatus itemStatus) { logStatus("play: succeeded for item " + itemId); } @Override public void onError(String error, int code, Bundle data) { } });}
