Hi Mark,

Thank you for reaching out to us and for sharing your concern.

I have tested the IMA SDK for Android basic sample app on an actual device (Google Pixel 3XL/Android 9), and updated the SDK version to 3.11.2. However, I was not able to replicate the issue you have encountered.

With this, could you also test the basic sample app on your end? And let me know if you will encounter the same issue

Hi

I use custom player to play advertisement media file and AdDisplayContainer will register com.google.ads.interactivemedia.v3.api.player.VideoAdPlayer to receive player event.

I also cannot replicate the issue in my devices, but firebase crash report still receive a lot of crash like below

Fatal log :

Hi there,


Thank you for reaching out to us.

For us to investigate further, could you provide the complete stack trace of the crash? Also, it will be a great help if you can share with us your test project where the issue is reproducible.

Hi there,

Thank you for your response. I have already responded to you regarding this issue, but it appears to be not posted here on this forum (probably my response has been sent to your private email, kindly check).

However, for your reference, please see below:

Upon testing your test project implementation, I was able to reproduce the issue (Please see attached screenshot: test1).

However, as I've checked the codes, it seems there's an issue, particularly on the destroyAdsManager in ImaSdkHandler.java (Attached screenshot: test2). The AdDisplayContainer is being destroyed in which this should be called when the associated AdsLoader is no longer needed, as per this document.

Could you try removing this (Attached screenshot: test3) or call the AdDisplayContainer destroy method after the ad completion? And let me know if you will encounter the same issue.

Let me know if you have further questions or clarification.

Hi,

We are getting the same crash in our production app when we use IMA version 3.11.3.

Can you please confirm if the order of destroy mentioned below is correct?

if (mAdsLoader !=null) {
    mAdsLoader.removeAdErrorListener(this);
    mAdsLoader.removeAdsLoadedListener(this);
    mAdsLoader = null;
}

 if (adDisplayContainer != null)
     adDisplayContainer.destroy();
 if (mAdsManager != null) {
     mAdsManager.removeAdErrorListener(this);
     mAdsManager.removeAdEventListener(this);
     mAdsManager.destroy();
 }

Thanks in advance.

Hi there,

 

Thank you for reaching out to us. With regard to the crash issue that you are facing, would you be able to update your IMA SDK to version 3.13.1, and see if you will encounter the same behavior?
