Error: No Static method isAtLeastR()Z

An app of mine with over 2,000 users recently crashed after I updated it.

I have not included any Deephost Extensions.

The application works normally for users who are already logged into their Google account.

However, new users are no longer able to log in with Google and the error only appears when clicking on the login button.



This is the only thread sbout that issue

Please provide a list of used extensions

Taifun

I did several tests in separate APK.

Everything points out that the error only appears when I try to login with Firebase Authentication using the ADMOB extension from developer @oseamiya

I fixed the error by returning the project’s old SDK.

Lucky I had saved it in my files
