IMA Android SDK supports fully automated ad playlists. This feature
inserts ad breaks into the content as specified inGoogle Ad Managerwhen trafficking your ads. It also greatly simplifies the video player code
necessary to support ad breaks, including pre-rolls, mid-rolls and post-rolls.
When trafficking the ads in Ad Manager, it is possible to specify various ad rules
like "always play ad break at the beginning of the content" or "play a one
minute ad break every 30 minutes of content".
When ads are requested, the ad server can return an ad playlist. The SDK
processes the playlist and automatically schedules the ad breaks that have been
specified.
Since Android uses the same video player for both ad and content playback,
if you plan to implement ad rules, you must save the playhead position of your
content when an ad starts, then seek to that position when the ad finishes.
Be sure to implement theVideoAdPlayerinterface in your video
player. This ensures that ad breaks are automatically inserted at the
times specified in Ad Manager.
TheCONTENT_PAUSE_REQUESTEDandCONTENT_RESUME_REQUESTEDevents are used to pause and resume the content when ad breaks are played. Refer
to the relevantAPI documentationfor details on these events.
Note:When the content has finished playing or
the user has stopped playback, be sure to callAdsLoader.contentCompletein order to signal to the SDK that the content is done. The SDK
then plays the post-roll ad break, if one has been scheduled. TheALL_ADS_COMPLETEDevent is raised when ALL ad breaks
have been played. In addition, note that content tracking begins wheninit()is called and you should always callinit()before playing content.
