多個 VOD 追蹤器並行

藍本

此情境中,有兩個工作階段並行執行兩個不同的媒體,並使用兩個不同的 MediaHeartbeat 例項。

除了有兩個工作階段並行執行兩個不同的媒體以外,此情境等同於沒有廣告的 VOD 播放情境。每一個工作階段會使用不同的 MediaHeartbeat 例項。

除非另有指定,否則網路呼叫與沒有廣告的 VOD 播放情境相同。

參數

心率工作階段

參數 附註
s:event:sid 唯一工作階段 ID 呼叫 trackSessionEnd 方法之前,存在於所有心率網路呼叫的唯一工作階段 ID。

MediaAnalyticsProviderMediaHeartbeat 這兩個例項追蹤個別的工作階段,每一個都具有其自己的唯一工作階段 ID。Charles 除錯工具或除錯記錄中的兩個工作階段,可透過使用工作階段 ID 值來加以識別。如要在 Android 上顯示此情境,請設定下列程式碼:

// 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.

// 4. Call trackSessionEnd() when the playback session is over. This method must
