Android: Check internet connection in webview

Question

I'm trying to test internet connectivity in a webview every time the application is launched.

I tried adapting an example I found, but it crashes. Whatever the state of my connection INFO returns me the same result

Try something like this:

ConnectivityManager connmgr = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
      if (connmgr != null){
          NetworkInfo[] netInfo = connmgr.getAllNetworkInfo();
          if (netInfo != null){
              for (int i = 0; i < netInfo.length; i++){
                  if (netInfo[i].getState() == NetworkInfo.State.CONNECTED){
                      // you are connected
                  }
              }
          }
      }
