@ammarahm-ed Any update on this??

[MamoshiSE]

Did anyone find solution for this? I am currently getting the crash: "Exception com.facebook.react.bridge.JSApplicationIllegalArgumentException: Error while updating property 'mediaview' of a view managed by: RNGADNativeView"

It's occuring very frequently for an high percentage of the app users.

[luongminh2410dev]

[luongminh2410dev]

work for me Add this code in node_modules/react-native-admob-native-ads/android/src/main/java/com/ammarahmed/rnadmob/nativeads/RNAdmobMediaView.java

     @Override
     protected void onDetachedFromWindow() {
        super.onDetachedFromWindow();
        // Add this
        if(this != null){
            this.removeAllViews();
        }
     }

I generated a release version and installed it only on my phone, I did some tests and realized that the app crashes only when the ad is a video, when it renders an image, it works fine.

Using NativeMediaView of course, I can't show a capture or anything like that because this only happens in production, Mr. @luongminh2410dev solution didn't work for me, unfortunately!

@lean098 Unfortunately, I encountered your same situation, but it worked for me I try to remove unfocused ads on the screen and when other ads show (which are videos), this avoids conflicts with the previous ads version:

• react-native: 0.71.3
