[IMA-SDK Android] When seeking to just before the Midroll ad immediately after the Preroll ad finishes, the expected events are not fired.

[pineapplevine1]

Hi IMA Team

When seeking to just before the Midroll ad immediately after the Preroll ad finishes, the expected events are not fired.
How can this be avoided?

Inquiry Overview
When seeking to just before the Midroll ad immediately after the Preroll ad finishes, the following two issues occur:
・Events from STARTED to COMPLETED are not fired
・The CONTENT_PAUSE_REQUESTED event is fired after the Midroll ad playback ends

Expected Behavior
・Events from STARTED to COMPLETED should be fired
・The CONTENT_PAUSE_REQUESTED event is fired before the Midroll ad playback

Reproduction Steps
1.Play the content
2.Seek to just before the Midroll ad
3.Wait until the Midroll ad playback is completed
4.LOADED and CONTENT_PAUSE_REQUESTED are fired, but events from STARTED to COMPLETED are not fired.
CONTENT_PAUSE_REQUESTED is fired after the Midroll ad playback ends.

Hi IMA Team

First, in response to whether it occurs on devices other than the Galaxy Note8: it does.
We confirmed the issue on a Pixel 9 running Android 16.

We have uploaded the app and the reproduction video via the URL.
Please refer inside the app for the ad and content that reproduce the issue.

The modifications to the app are below.

・Added seek processing (lines 10-12)
/googleads-ima-android-3.37.0-0/ExoPlayerExample/app/src/main/java/com/google/ads/interactivemedia/v3/samples/exoplayerexample/MyActivity.java＞buildAdEventListener()

public AdEvent.AdEventListener buildAdEventListener() { logText = findViewById(R.id.logText); logText.setMovementMethod(new ScrollingMovementMethod()); return event -> { AdEvent.AdEventType eventType = event.getType(); if (eventType == AdEvent.AdEventType.AD_PROGRESS) { return; } else if (eventType == AdEvent.AdEventType.CONTENT_RESUME_REQUESTED) { player.seekTo(781500); } String log = "IMA event: " + eventType; if (logText != null) { logText.append(log + "\n"); } Log.i(LOG_TAG, log); }; }

・Added DRM processing
/googleads-ima-android-3.37.0-0/ExoPlayerExample/app/src/main/java/com/google/ads/interactivemedia/v3/samples/exoplayerexample/MyActivity.java＞initializePlayer()

private void initializePlayer() { // Widevine DRM compatible DASH content Uri contentUri = Uri.parse("DRM compatible DASH content URL"); Uri adTagUri = Uri.parse(SAMPLE_VAST_TAG_URL); String licenseUrl = "license URL"; String customerData = "customerData"; // --- HttpDataSource.Factory with custom headers --- HttpDataSource.Factory httpDataSourceFactory = new DefaultHttpDataSource.Factory() .setDefaultRequestProperties( Collections.singletonMap("acquirelicenseassertion", customerData) ); // --- Build DRM session manager --- MediaDrmCallback drmCallback = new HttpMediaDrmCallback(licenseUrl, httpDataSourceFactory); DefaultDrmSessionManager drmSessionManager; drmSessionManager = new DefaultDrmSessionManager.Builder() .setUuidAndExoMediaDrmProvider( C.WIDEVINE_UUID, uuid -> { try { return FrameworkMediaDrm.newInstance(uuid); } catch (UnsupportedDrmException e) { throw new RuntimeException(e); } } ) .build(drmCallback); // --- Regular data source factory --- DataSource.Factory dataSourceFactory = new DefaultDataSource.Factory(this); // --- Integrate DRM and AdsLoader into MediaSourceFactory --- MediaSource.Factory mediaSourceFactory = new DefaultMediaSourceFactory(dataSourceFactory) .setDrmSessionManagerProvider(unused -> drmSessionManager) .setLocalAdInsertionComponents(unusedAdTagUri -> adsLoader, playerView); // --- Create player --- player = new ExoPlayer.Builder(this) .setMediaSourceFactory(mediaSourceFactory) .build(); playerView.setPlayer(player); adsLoader.setPlayer(player); // --- Configure MediaItem (DRM + Ads) --- MediaItem mediaItem = new MediaItem.Builder() .setUri(contentUri) .setAdsConfiguration(new MediaItem.AdsConfiguration.Builder(adTagUri).build()) .setDrmConfiguration(new MediaItem.DrmConfiguration.Builder(C.WIDEVINE_UUID) .setLicenseUri(licenseUrl) .build()) .build(); player.setMediaItem(mediaItem); player.prepare(); player.setPlayWhenReady(false); }

Hi,

Thanks for providing the details.

I ran your sample project on a Pixel 9 running Android 16 and was able to see the ad events, from STARTED to COMPLETED, for the Mid-roll ad immediately after the Pre-roll ad finished. For further investigation, could you please confirm if there are any other affected devices apart from the Samsung Galaxy Note 8 and the Pixel 9?

Additionally, It is always recommended to use the latest SDK version 3.38.0. If the issue still occurs after updating, please let us know.

Thanks,

Hi IMA Team

Regarding this issue, it also reproduced on a Pixel 5 with Android 14 and SDK version 3.38.0.
We uploaded the SDK 3.38.0 app via the URL.
We will reattach in this thread the event logs for the occurrence case and the normal case.
Please check again.

We will explain the flow of the issue again.

1.Right after the preroll ad, we seek in the source. After LOADED arrives, the first midroll ad is shown.
 We believe STARTED–COMPLETED should fire here, however they don’t.
2.After the first midroll ad ends, CONTENT_PAUSE_REQUESTED appears and then the content plays.
 We believe CONTENT_PAUSE_REQUESTED should come before the midroll ad playback, however it comes afterwards.

Also, normally during ads a label like “Ad 2 of 2” appears at the lower left and operations are disabled.
When the issue occurs, that label does not appear.
However, since operations are still disabled, it should be possible to distinguish ad vs content.

Best Regards.
