use this solution code your app not crash:

C#

public boolean checkInternetConnectionALL() {
       ConnectivityManager conmag = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
       // for all active Network connection

       NetworkInfo info = conmag.getActiveNetworkInfo();
       if (info != null && info.isConnected())
           return true;
       else
           Toast.makeText(context.getApplicationContext(), "No Internet Connection", Toast.LENGTH_LONG).show();

       return false;
   }
