Developers
Collecting media data is critical for tracking user behavior when your customers consume video or audio content through Android and iOS mobile applications or on the web. mParticle provides a toolset for integrating media analytics into your customer experience.
The mParticle Media SDK provides a dedicated API for tracking common media events including session start/end, play, pause, and other milestones, as well as logging recurring advertising impressions and chapters for segmented content.
The mParticle Media SDK works hand in hand with the mParticle platform. Data logged from the Media SDK is forwarded to the Android SDK and then forwarded to any included integrations.
The mParticle Media SDK is compatible with Adobe Analytics for Media, supporting the full range of media-related events including heartbeat events. This simplifies an otherwise complicated and error-prone process of setting up media session event tracking and Adobe Heartbeat yourself.
Before you can begin using the Media SDK, you need to have a working instance of the mParticle core SDK. Please see the core SDK getting started section for more details.

}
The Android Media SDK provides a MediaSession
object. Each MediaSession
object represents a single end to end media experience and relates one-to-one to a piece of content. For example, if a customer is watching a video, pausing, seeking and scrubbing, that is considered a single session. If they stop the video, and play another piece of content, that is a new session.
val mediaSession = MediaSession.builder {
title = "Media Title" // Custom media Title, added as content_title for media events
mediaContentId = "123" // Custom media ID, added as content_id for media events
duration = 1000 // Duration in milliseconds, added as content_duration for media events
streamType = StreamType.LIVE_STEAM // Stream Type (OnDemand, Live, etc.), added as stream_type for media events
contentType = ContentType.VIDEO // Content Type (Video or Audio), added as content_type for media events
mediaContentCompleteLimit = 90 // Marks content as completed when user reaches 90%
}

Summary events are automated events that contain an accumulated record of what occured during a session, individual segments, and individual ads.
A Session Summary event tracks from when a MediaSession
is initialized to when it’s de-initialized or when logMediaSessionEnd
is called. The more accurate and detailed developers are with logPlay
, logPause
, logAdStart
, and other media events, the more accurate the summary data will be.
The following table explains the different parts of the Session Summary event.
Session Summary Keys | Description |
---|---|
“media_session_id” | A unique identifier automatically created for each session |
“content_id” | A unique identifier that can set by the user when initializing a session |
“content_title” | The title of the content. Can be set by the user when initializing a session |
“media_session_start_time” | Timestamp created on logMediaSessionStart event |
“media_session_end_time” | Timestamp of most recent valid event |
“media_time_spent” | Total seconds user spent on this session |
“media_content_time_spent” | The total seconds user spent playing content |
“media_content_complete” | True if logMediaContentEnd was called or if user progressed past percentage set in MediaSession.mediaContentCompleteLimit |
“media_session_segment_total” | The number of segments progressed into by the user |
“media_total_ad_time_spent” | The total seconds that ads played during this session |
“media_ad_time_spent_rate” | The parcentage of playback time that was ad content |
“media_session_ad_total” | The number of ads played in the media session |
“media_session_ad_objects” | An array of unique identifiers for ads played during this media session |
A Segment Summary event tracks from when logSegmentStart
is called to when either logSegmentSkip
or logSegmentEnd
is called. Segments could be the chapters of an audiobook or scenes in a movie.
The following table explains the different parts of the Segment Summary event.
Segment Summary Keys | Description |
---|---|
“media_session_id” | A unique identifier automatically created for each session |
“content_id” | A unique identifier that can set by the user when initializing a session |
“segment_title” | The title of the segment |
“segment_index” | The index of the segment |
“segment_start_time” | Timestamp created on logSegmentStart event |
“segment_end_time” | Timestamp of most recent valid event in segment |
“media_segment_time_spent” | Total seconds user spent on this segment |
“segment_completed” | True if logSegmentEnd was called to end the segment |
“segment_skipped” | True if logSegmentSkip was called to end the segment |
An Ad Summary event tracks from when logAdStart
is called to when either logAdSkip
or logAdEnd
is called.
The following table explains the different parts of the Ad Summary event.
Ad Summary Keys | Description |
---|---|
“media_session_id” | A unique identifier automatically created for each session |
“ad_break_id” | A unique identifier that can set by the user when initializing an ad break |
“ad_content_id” | A unique identifier that can set by the user when initializing an ad |
“ad_content_title” | The title of the ad |
“ad_content_start_time” | Timestamp created on logAdStart event |
“ad_content_end_time” | Timestamp of most recent valid event in segment |
“ad_completed” | True if logAdEnd was called to end the segment. |
“ad_skipped” | True if logAdSkip was called to end the segment. |
Once your session is instantiated, you will need to trigger a SessionStart
. This should be done at the moment the user interacts with your content. For example, if the media is set to trigger on a user click, and your player fires a play
event when the content starts, the session must begin before the play
event.
// set playhead
val currentPlayheadPosition = 300
// create any custom attributes
val customAttributes = mapOf(
"<media attribute key>" to "<media attribute value>",
"<custom attribute key>" to "<custom attribute value>"
)
// build Options object for logging Media Session Start
val options = Options(currentPlayheadPosition, customAttributes)
// call Media Session Start heartbeat event
mediaSession.logMediaSessionStart(options)
val options = Options(currentPlayheadPosition = 300)
mediaSession.logPlay(options)
pause
val options = Options(currentPlayheadPosition = 300)
mediaSession.logPause(options)
val options = Options(currentPlayheadPosition = 300)
mediaSession.logMediaContentEnd(options)
val options = Options(currentPlayheadPosition = 300)
mediaSession.logMediaSessionEnd(options)
In most cases, advertising comes in as a series of Ad Breaks
each containing numerous Ads
. The Media SDK provides both sets of functionality so that you can track this behavior.
AdBreakStart
eventmediaSession.logAdBreakStart {
id = "123456" // included as ad_break_id for Ad Break Start/End and Summary events
title = "pre-roll" // ad_break_title
duration = 6000 // ad_break_duration
}
AdStart
eventmediaSession.logAdStart {
id = "4423210" // included as ad_content_id for Ad Start/End and Summary events
advertiser= "Moms Friendly Robot Company" // ad_content_advertiser
title= "What?! Nobody rips off my kids but me!" // ad_content_title
campaign= "MomCorp Galactic Domination Plot 3201" // ad_content_campaign
this.duration = 60000 // ad_content_duration
creative= "A Fishful of Dollars" // ad_content_creative
siteId= "moms" // ad_content_site_id
placement= "first" // ad_content_placement
position= 0 // ad_content_position
}
AdEnd
or AdSkip
when appropriatemediaSession.logAdEnd()
AdBreakEnd
event when all ads have completedmediaSession.logAdBreakEnd()
The Media SDK will generate a MediaEvent
for client-side kits such as Adobe Media Analytics, however the event can be converted to look just like a typical mParticle custom event that may be used to create audiences, used in calculated attributes, and sent to most mParticle integrations for analysis and activation.
To enable Custom event generation, pass a boolean to the initialization of your MediaSession
to enable the Log Custom Event feature:
val mediaSession = MediaSession.builder {
title = "Media Title"
mediaContentId = "123"
duration = 1000
streamType = StreamType.LIVE_STEAM
contentType = ContentType.VIDEO
logMPEvents = true
}
To log a custom event that does not correspond with the supported Media Session events, you can generate a completely custom event:
val mpEvent = mediaSession.buildMPEvent("Milestone", mapOf(
"type" to "95%"
))
MParticle.getInstance()?.logEvent(mpEvent)
The Media SDK will generate Custom events per the specification below.
The Media SDK exposes methods that will trigger Media Events based on the most common player functions. The Media SDK maps every MediaSession
API to a predefined Custom event name. The table below details all of the predefineed Media Events:
Media Session API | Custom Event Name |
---|---|
mediaSession.logPlay() | ‘Play’ |
mediaSession.logPause() | ‘Pause’ |
mediaSession.logMediaContentEnd:() | ‘Media Content End’ |
mediaSession.logMediaSessionStart() | ‘Media Session Start’ |
mediaSession.logMediaSessionEnd() | ‘Media Session End’ |
mediaSession.logSeekStart() | ‘Seek Start’ |
mediaSession.logSeekEnd() | ‘Seek End’ |
mediaSession.logBufferStart() | ‘Buffer Start’ |
mediaSession.logBufferEnd() | ‘Buffer End’ |
mediaSession.logUpdatePlayheadPosition() | ‘Update Playhead Position’ |
mediaSession.logAdClick() | ‘Ad Click’ |
mediaSession.logAdBreakStart() | ‘Ad Break Start’ |
mediaSession.logAdBreakEnd() | ‘Ad Break End’ |
mediaSession.logAdStart() | ‘Ad Start’ |

mediaSession.logSegmentSkip() | ‘Segment Skip’ |
mediaSession.logUpdateQoS() | ‘Update QoS’ |
The media attributes below are a list of all available for capturing valuable information with every media event listed above. The customer will choose which attributes will be logged for each event to best describe the session characteristics for that event at that time. Should you require attributes not listed below, you may add your own media attributes.
Note: Depending on your player, you will need to either enable the callback method to receive updates for playhead position and quality of service (QoS) or set up a job to frequently poll for the current values.

In cases where you may need to handle some custom functionality when a media event occurs, the Media SDK provides a mediaEventListener
which will provide a callback.
For example, if you need to trigger a custom function when Play or Pause occurs:
mediaSession.mediaEventListener = { mediaEvent ->
// Some custom callback method defined by user
// Should only trigger when play or pause is fired
when (mediaEvent.eventName) {
MediaEventName.PLAY, MediaEventName.PAUSE -> {
val mpEvent = mediaEvent.toMPEvent()
MParticle.getInstance()?.logEvent(mpEvent)
}
}
}
