How to solve the error "com.google.android.gms.ads.internal.util.*: Unable to obtain a JavascriptEngine." when loading admob ads

[Jack Jack]

When loading admob ads, I encountered a lot of admob "com.google.android.gms.ads.internal.util.*: Unable to obtain a JavascriptEngine." errors. How can I solve this problem? I have consulted a lot of open source information and found that everyone has this problem. I look forward to the answers from kind people. Thank you~

I have checked that the ads are not loaded using privileged processes, so I really don't understand why, especially when users in Brazil use my app, 80% of the ads cannot be loaded successfully

Hi,

To investigate the issue, please confirm the SDK version you were using and share the crash log with us. Also, please let us know if the issue is happening on any particular device.

Regarding ads are not loading concerns. Please go through the Common reasons for ads not showing for more details. 

Could you try once by enabling the Ad Inspector? And then share the export request and response file generated from the Ad Inspector to us along with app ID & ad unit ID for further investigation.

Note:You can export the ad response only after you add your test device in the AdMob UI. For detailed info refer to this AdInspector document.
