Admob banner ad not loading in android P

Question

I am using AdMob banner ads in multi-process. It is working fine on API version lower than 29 but on android-P, it is giving this error.

 com.google.android.gms.ads.internal.webview.s: Webview initialization failed.

I have initialized MobileAds in application class. i also tried to initialize in other process in which i am using ads but no luck.

Notice this line in your error: " Caused by: java.lang.RuntimeException: Using WebView from more than one process at once with the same data directory is not supported."

It means your app is using 2 or more processes and you need to set a different WebView directory for each process (the main process already have the default folder), as explained in my question and answer here.

On Android 9.0 API 28, call WebView.setDataDirectorySuffix("any-folder-name") when the second process is running, before you use any WebView.

This is insanity on steroids... They should have done a better job providing a proper trouble shooting - ie. write something about setDataDirectorySuffix in the log output. If you upgrade and do not test the part of you app with a web view you might never know until it is too late... – slott May 11 '19 at 08:07

And what if you see this bug, but you didn't start any new processes? Where you should put this suffix method? Btw, bug appears mostly on a Samsung devices. – Johnny Five Apr 07 '20 at 11:46

in case when you deals with ads, in application class

try {
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.P) {
            val process = getProcessName()
            if (packageName != process) WebView.setDataDirectorySuffix(process)
        }

        MobileAds.initialize(this)
        AudienceNetworkAds.initialize(this)

    } catch (e: Error) {
        Timber.e(e)
    } catch (e: Exception) {
        Timber.e(e)
    }
