This isn't the right way to fix the disallow useragent issue on Google. They're pretty clear on how they expect this to be implemented: https://developers.googleblog.com/2016/08/modernizing-oauth-interactions-in-native-apps.html.

Better using the user's actual UserAgent and replace wv from it instead of the hard coded one
mWebView.getSettings().setUserAgentString(mWebView.getSettings().getUserAgentString().replace("; wv", ""));

P.S. I have open the PR for this issue, however this library seems no longer supported by the original author, you may consider using other OAuth RN library.
