Use this

ConnectivityManager connectivityManager = (ConnectivityManager) this.getSystemService(Activity.CONNECTIVITY_SERVICE);
if(connectivityManager.getActiveNetworkInfo().isConnected()){
  mfnWebView.getSettings().setCacheMode(WebSettings.LOAD_DEFAULT);
  mfnWebView.loadUrl(url);
}
else{
  mfnWebView.getSettings().setCacheMode(WebSettings.LOAD_CACHE_ELSE_NETWORK);
  mfnWebView.loadUrl(url);
}

Mandatory permissions :- INTERNET, ACCESS_NETWORK_STATE, ACCESS_WIFI_STATE
