RE: [google-admob-ads-sdk] collapsible banner ads cause memory leaks.

[Mobile Ads SDK Forum Advisor]

Hi Gouranga,

Thank you for contacting the Mobile Ads SDK Support team.

After I reviewed your concern, I understand that you have memory leaks in your application for collapsible banner ads

1. Please refer to the sample application for the implementation and guide for collapsible banner ads. When implementing ads in your application, it is very important to follow AdMob Policies, as well as Implementation Guidelines to avoid any issues.  Kindly double-check your implementation so that Ads load and show as expected. You may refer to Banner Implementation Guidelines, as well as the Recommended and Disallowed implementation guidance for further reference.

If the issue still persists, then please provide the following information privately for further investigation:

• app ID
• ad unit ID
• Charles proxy logs
• SDK Version being used
• Video recording of the issue
• Sample project reproducing the issue

2. Yes, there is a potential for policy issues when an App-Open ad appears on top of an expanded popup window containing a collapsible banner, especially if it is not implemented correctly. Here's why:

Policy Violations:

• Disruptive Ads: Google's AdMob policies prohibit ads that are disruptive to the user experience. An App-Open ad appearing on top of another ad unit can be disruptive and make it difficult for users to interact with the app's content.
• Oversaturation: Showing multiple ads simultaneously can create an over-saturated experience for users and violate the policy against excessive ad volume.
• Accidental Clicks: Users might accidentally click the App-Open ad when trying to interact with the underlying content, leading to misleading clicks and user frustration.

You can provide the following details via reply privately to the author option or directly provide it to the link below.

If the file(s) you are looking to share are less than 25mb in total you can attach them to this case on your next reply. If you are having trouble attaching your file to this case or if your file(s) are larger than 25mb, you can share your files with me by performing the following steps:

I have uploaded sample project. Please check it.

To reproduce the memory leak.

Open the app.

Let the collapsible banner ad load and it will show as expanded view.

Do NOT collapse the banner ad. Now kill the app from recent apps.

Observe the logcat in android studio, it will have the following error logs.

[Rana]

Do you get any solution? I'm also getting the same problem.

[Mobile Ads SDK Forum Advisor]

Hello Rana,

Thanks for bumping up the thread.

Would you be able to reproduce the issue in our Banner example as well?

If you do, can you provide the following details?

• Steps to reproduce
• Stack trace
• Screenshot(s) or recording(s) captured in memory profiler that show memory leak

Regards,
Joshua

Ok new findings, it only happens when the banner is expanded, if banner is collapsed no memory leak error is shown.

It reproduces with the Banner example as well..

Steps to reproduce: Start the app, when the banner shows in expanded mode, press back button on device to end Activity

Banner example with added extras:

private void loadBanner() {
// Create a new ad view.
adView = new AdView(this);
adView.setAdUnitId(AD_UNIT_ID);
adView.setAdSize(getAdSize());

// Replace ad container with new ad view.
adContainerView.removeAllViews();
adContainerView.addView(adView);

Bundle extras = new Bundle();
extras.putString("collapsible", "bottom");
extras.putString("collapsible_request_id", UUID.randomUUID().toString());
// Start loading the ad in the background.

AdRequest adRequest = new AdRequest.Builder()
.addNetworkExtrasBundle(AdMobAdapter.class, extras)
.build();
adView.loadAd(adRequest);
}

 

If Activity is Destroyed while banner is expanded, this will show on Logcat:

android.view.WindowLeaked: Activity com.google.android.gms.example.bannerexample.MyActivity has leaked window android.widget.PopupWindow$PopupDecorView{612b570 V.E...... R......D 0,0-719,763} that was originally added here (Ask Gemini)
