Android IMA SDK [ Error: Attempted to send bridge message after cleanup ]

[gourav...@gmail.com]

Hi There,

I am using 3.21.2 IMA android SDK. I tried master branch of IMA Advanced Example.

In our code, on ALL_ADS_COMPLETED event, we used to destroy adDisplayContainer but in the latest sdk versions, this API is deprecated and instead we need to use adsLoader.release and as per the documentation; this is recommended to call when i get  ALL_ADS_COMPLETED event.

But in IMA sample, i can see only adsManager is being destroyed so i thought of keeping adsLoader.release() there; but after this i am getting the following error in ADB. Please check the screenshot as well.

Hi,

It is not causing any known side effect as far i checked but don't know the reason behind it and certainly not sure the future impacts of it. 

Prior to 3.21.0 version, we were calling adDisplayContainer.destroy() and then adsManager.destroy() but after this change in 3.21.0 onwards, adDisplayContainer.destroy() is not there and instead we need to use adsLoader.release() [ I can see inside obfuscated code that in this release method, IMA SDK internally calling adDisplayContainer.destroy() ]

So not sure what should be the correct flow now, 

1. Should I not call adsLoader.release at the time of ALL_ADS_COMPLETED event ? This is what it is in IMA Advanced Example as well.

2. OR there is an underlying bug because of which i am seeing this error

Hi Gourav,

Thank you for reporting this issue. I was able to replicate the error messages that you are seeing using the information that you’ve shared earlier. I’ll check this together with my teammates and will give you an update as soon as we have our findings.

Hi Sherwin,

Please let me know if you have any updates from the team.

Hi Gourav,

Thanks for following up.

The team confirms that this warning is occurring, however it is harmless and can be ignored. Next update of the Android SDK should remove this warning, you can keep an eye on our release history for updates. Also, the ALL_ADS_COMPLETED event is an acceptable place to call adsLoader.release().

Hi Sherwin,

Thanks for your response. I will wait for the next release. :)

Hi Gourav,

The SDK version 3.21.4 has been released with the fix below. Let me know if this version would solve the issue on your end.

- Removes a harmless warning message related to calling adsLoader.release() after the webview has been destroyed.

Thanks a lot Sherwin. I will surely check it and let you know.

Hi Sherwin,

I checked it in 3.21.4 and still see this log and now it is in the Error category.

You can do the same by going BG/FG. Scenario is following in IMA Advanced example app,

1. Configure this ad. It has pre/mid/post ads

https://pubads.g.doubleclick.net/gampad/ads?sz=640x480&iu=/124319096/external/ad_rule_samples&ciu_szs=300x250&ad_rule=1&impl=s&gdfp_req=1&env=vp&output=vmap&unviewed_position_start=1&cust_params=deployment%3Ddevsite%26sample_ar%3Dpremidpostpodbumper&cmsid=496&vid=short_onecue&correlator=

2. when the pre roll is playing, do BG/FG.

3. Once pre roll ends, seek to the end and now when the ads are playing go to BG/FG.

4. Once postroll completes, you will see the errors.

5. Strange thing is now that this error persists on the replay of the media as well.

Hi Sherwin,

Please let me know if this issue is fixed in 3.22.0.

I am seeing one error in 3.22.0 and 3.21.2, it may require some flow change. 

Can you please suggest what change is required ? Earlier we were reusing DisplayContainer on changing the media. Now do we need to use a fresh instance of DisplayContainer every time on change media.

java.lang.IllegalArgumentException: A given DisplayContainer may only be used once

I am using adsLoader.release() and as per definition 

"Frees resources from the BaseDisplayContainer as well as the underlying WebView. This should occur after disposing of the BaseManager using BaseManager.destroy() and after the manager has finished its own cleanup, as indicated by AdEvent.AdEventType.ALL_ADS_COMPLETED"

If I use a fresh instance of adDisplayContainer on change media then in the next media, i don't see Ad Video Frame, only Ad audio and ad timer, learnmore (UI ) is visible.

Hi Gourav,

Thanks for bringing this to our attention. For our test reference, could you share with us a sample project file demonstrating this exception error? This could be a new issue that is not related to the one you’ve reported initially.
