Sample Code

In this scenario, buffering occurs when the VOD content is played back.

Android

To view this scenario in Android, set up the following code:

// Set up mediaObject 

MediaObject mediaInfo = MediaHeartbeat.createMediaObject( 
  Configuration.MEDIA_NAME,  
  Configuration.MEDIA_ID,  
  Configuration.MEDIA_LENGTH,  
  MediaHeartbeat.StreamType.VOD 

); 

HashMap<String, String> videoMetadata = new HashMap<String, String>(); 
videoMetadata.put(CUSTOM_KEY_1, CUSTOM_VAL_1); 
videoMetadata.put(CUSTOM_KEY_2, CUSTOM_VAL_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, videoMetadata); 

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

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

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

// 3. Track the MediaHeartbeat.Event.BufferStart event when the video player  
//    goes into the buffering state and begins to buffer content. 
_mediaHeartbeat.trackEvent(MediaHeartbeat.Event.BufferStart, null, null); 

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

// 4. Track the MediaHeartbeat.Event.BufferComplete event when the video player  
//    goes into the buffering state and begins to buffer content. 
_mediaHeartbeat.trackEvent(MediaHeartbeat.Event.BufferComplete, null, null); 

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

// 5. Call trackComplete() when the playback reaches the end, i.e., when the 
//    video completes and finishes playing. 
_mediaHeartbeat.trackComplete(); 

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

// 6. Call trackSessionEnd() when the playback session is over. This method must  
//    be called even if the user does not watch the video to completion.

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

// 3. Track the trackEvent:ADBMediaHeartbeatEventBufferStart event when the  
//    video player goes in buffering state and begins to buffer content. 
[_mediaHeartbeat trackEvent:ADBMediaHeartbeatEventBufferStart  
               mediaObject:nil  
               data:nil]; 
....... 
....... 

// 4. Track the trackEvent:ADBMediaHeartbeatEventBufferComplete event when  
//    the video player goes in buffering state and begins to buffer content. 
[_mediaHeartbeat trackEvent:ADBMediaHeartbeatEventBufferComplete
