Um rastreador de VOD para várias sessões

Cenário

Neste cenário, a instância MediaHeartbeat é usada para criar duas sessões separadas em sequência.
Esse cenário é igual ao cenário Reprodução de VOD sem anúncios .

Parâmetros

Sessão do Heartbeat

Parâmetro
Valor
Notas  
s:event:sid
ID exclusiva da sessão
Uma ID de sessão exclusiva que existe em todas as chamadas de rede do heartbeat até trackSessionEnd

Código de exemplo

Android

Para criar duas instâncias de MediaHeartbeat para dois reprodutores de mídia, configure o seguinte código:
public class MediaAnalyticsProvider implements MediaHeartbeatDelegate { 

  private MediaPlayer _player; 
  private MediaHeartbeat _heartbeat; 

  public MediaAnalyticsProvider(MediaPlayer player) { 
      if (player == null) { 
          throw new IllegalArgumentException("Player reference cannot be null."); 
      } 
  } 

  _player = player;  
  _player.addObserver(this); 

  // Media Heartbeat initialization 
  MediaHeartbeatConfig config = new MediaHeartbeatConfig(); 

  config.trackingServer = HEARTBEAT_TRACKING_SERVER; 
  config.channel = HEARTBEAT_CHANNEL; 
  config.appVersion = HEARTBEAT_SDK; 
  config.ovp = HEARTBEAT_OVP; 
  config.playerName = PLAYER_NAME; 
  config.ssl = false; 
  config.debugLogging = true;  
  _heartbeat = new MediaHeartbeat(this, config); 
} 

@Override 
public MediaObject getQoSObject() { 
  return MediaHeartbeat.createQoSObject(BITRATE, STARTUP_TIME, FPS, DROPPED_FRAMES); 
} 

@Override 
public Double getCurrentPlaybackTime() { 
  return _player.getCurrentPlaybackTime(); 
} 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
  super.onCreate(savedInstanceState); 
  setContentView(R.layout.activity_main); 

  // Bootstrap the AppMeasurement library.  
  Config.setContext(this.getApplicationContext()); 

  // Create the MediaPlayer instance.  
  _player = new MediaPlayer(); 

  // Create the MediaAnalyticsProvider instance and 
  // attach it to the MediaPlayer instance.  
   _analyticsProvider = new MediaAnalyticsProvider(_player); 

  // Load the main media content.  
   Uri uri = Uri.parse("android.resource://" + getPackageName() + "/" + R.raw.media1);  
   _player.loadContent(uri); 
} 

Para exibir a primeira sessão usando a instância MediaAnalyticsProvider (ou seja, MediaHeartbeat ) no Android, configure o seguinte código:
// Set up mediaObject 
MediaObject mediaInfo = MediaHeartbeat.createMediaObject( 
  Configuration.MEDIA_NAME,  
  Configuration.MEDIA_ID,  
  Configuration.MEDIA_LENGTH,  
  MediaHeartbeat.StreamType.VOD 
); 

HashMap<String, String> mediaMetadata = new HashMap<String, String>(); 
mediaMetadata.put(CUSTOM_VAL_1, CUSTOM_KEY_1); 
mediaMetadata.put(CUSTOM_VAL_2, CUSTOM_KEY_2); 

// 1. Call trackSessionStart() when the user clicks Play or if autoplay is used,  
//    i.e., there is an intent to start playback.  
_mediaHeartbeat.trackSessionStart(mediaInfo, mediaMetadata); 

...... 
...... 

// 2. Call trackPlay() when the playback actually starts, i.e., when the first  
//    frame of main content is rendered on the screen.  
_mediaHeartbeat.trackPlay(); 

....... 
....... 

// 3. Call trackComplete() when the playback reaches the end, i.e., when the 
//    media completes and finishes playing. 
_mediaHeartbeat.trackComplete(); 

........ 
........ 

// 4. Call trackSessionEnd() when the playback session is over. This method must  
//    be called even if the user does not watch the media to completion.  
_mediaHeartbeat.trackSessionEnd(); 

........ 
........ 

Para exibir a segunda sessão, você pode usar a mesma instância MediaAnalyticsProvider ( MediaHeartbeat ) da primeira sessão, só que para uma nova sessão:
// Set up mediaObject 
MediaObject mediaInfo = MediaHeartbeat.createMediaObject( 
  Configuration.MEDIA_NAME,  
  Configuration.MEDIA_ID,  
  Configuration.MEDIA_LENGTH,  
  MediaHeartbeat.StreamType.VOD 
); 

HashMap<String, String> mediaMetadata = new HashMap<String, String>(); 
mediaMetadata.put(CUSTOM_VAL_1, CUSTOM_KEY_1); 
mediaMetadata.put(CUSTOM_VAL_2, CUSTOM_KEY_2); 

// 1. Call trackSessionStart() when the user clicks Play or if autoplay is used,  
//    i.e., there is an intent to start playback.  
_mediaHeartbeat.trackSessionStart(mediaInfo, mediaMetadata); 

...... 
...... 

// 2. Call trackPlay() when the playback actually starts, i.e., when the first  
//    frame of main content is rendered on the screen.  
_mediaHeartbeat.trackPlay(); 

....... 
....... 

// 3. Call trackComplete() when the playback reaches the end, i.e., when the  
//    media completes and finishes playing. 
_mediaHeartbeat.trackComplete(); 

........ 
........ 

// 4. Call trackSessionEnd() when the playback session is over. This method  
//    must be called even if the user does not watch the media to completion.  
_mediaHeartbeat.trackSessionEnd(); 

........ 
........ 

iOS

Para criar duas instâncias de MediaHeartbeat para dois reprodutores de mídia, insira:
@interface MediaAnalyticsProvider : NSObject <ADBMediaHeartbeatDelegate> 

@end    

@implementation { 
  MediaPlayer *_player; 
} 

- (instancetype)initWithPlayer:(AVPlayer *)player { 
  if (self = [super init]) {

// 1. Call trackSessionStart when the user clicks Play or if autoplay is used,  
//    i.e., there's an intent to start playback.
