Hi @rahullraghuwanshi can you provide some more details?

• which version of google ads are you using?
• what mediation packages are in use?
• do you have any replication steps and a sample application?
• do you have a complete stack trace or charles log?

Hi @NVentimiglia

Here are the details :

• Google ads version : 22.2.0
• No we are not using any mediation package we are using.
• No we are not able to reproduce this error only able to get.

Caused by android.os.RemoteException: Remote stack trace: at com.android.server.wm.DisplayHashController.getDisplayHashAlgorithms(DisplayHashController.java:250) at com.android.server.wm.DisplayHashController.getSupportedHashAlgorithms(DisplayHashController.java:145) at com.android.server.wm.WindowManagerService.getSupportedDisplayHashAlgorithms(WindowManagerService.java:9818) at android.view.IWindowManager$Stub.onTransact(IWindowManager.java:3180) at com.android.server.wm.WindowManagerService.onTransact(WindowManagerService.java:1600)

Hi @rahullraghuwanshi

It is pretty hard to diagnose issues without replication steps. Can you open up a support case on https://groups.google.com/g/google-admob-ads-sdk ? This request will be sent over to the SDK team which is better equipped to solve this specific issue.

We have closed this issue as we were unable to reproduce it on our end.

@rahullraghuwanshi

As per @NVentimiglia's previous comment, this appears to be an issue with the Google Mobile Ads SDK rather than mediation. Once you have gathered sufficient information, such as reproducing steps, a full stack trace, and a sample project, you can open a support case using the contact form at https://developers.google.com/admob/android/support.
