Android SDK API Methods & Properties

Scenario	Method / Property	DTVR	DAR	Digital Audio	DCR	International (Germany)	Description
Initialize	AppSDK()	✔	✔	✔	✔	✔	Used to create a new instance of the SDK object
Measurement	play()	✔	✔	✔	✔	✔	Used when there is an ID3 fed product such as DTVR and the client does not want to send in all the CMS metadata that is sent in loadMetadata. This allows the client to send in at least the required “channel name” value associated to the ID3 feed. If this is not called then the “channel name” value populated will be the default value of “defaultChannelName”.
Measurement	loadMetadata()	✔	✔	✔	✔	✔	Used when there is a preroll ad that needs to be associated with content metadata. The loadmetadata will first be called to populate the content metadata values and then the loadMetadata for ad metadata will be called. This allows sending a content ping with the ad info, even if the user bails out during the preroll ad.
Measurement	sendID3()	✔	✘	✘	✘	✘	Used to send the ID3 metadata.
Measurement	setPlayheadPosition()	✘	✘	✔	✔	✔	Used to send the playhead position.
Measurement	stop()	✔	✘	✔	✔	✔	Used when playback is paused and when switching between ad and content or content and ad.
