gradle not coordinated with the project

I am using android studio version 4.1.3 and gradle version 6.8.3 . My target sdk version for the project is API 26.
After clicking on sync the project, the result seems have no problem but after clicking on run app, I have some errors. One of them says,

I have seen the Error:(9, 5) error: resource android:attr/dialogCornerRadius not found
But again the problem is not solved
I don't know what should I do?

//Google AdMob AppLovin mediation
implementation 'com.applovin:applovin-sdk:9.15.2'

How to solve this issue?

Not sure if you've resolved this issue yet, but I'd highly recommend switching over to MAX, their docs are straightforward and the product is taking the industry by storm.

The Screen Shot
R class also showed error
I've cleaned the project, invalidate caches/restart,
It's not gone, I am using the firebase core implementation 'com.google.firebase:firebase-core:16.0.1'

This can result in several reasons.
Make sure you are using an updated version of android-gradle-plugin
Make sure there are no dependency version clashed in build.gradle file.
Check whether your XML resources don't have errors.
Hope this helps!
