Answer 1

You can check internet connection of device by using isConnected method of this class. Then you dismiss progress dialog when there is not internet connection

public class InternetConnectionDetector
{
   private Context context;

   public InternetConnectionDetector(Context context)
   {
       this.context = context;
   }

   public boolean isConnected()
   {
       ConnectivityManager connectivityManager = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);

       //There are changes after apk lollipop while detecting internet connection:
       //if user's os newer then lollipop:
       if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP)
       {
           Network[] networks = connectivityManager.getAllNetworks();
           NetworkInfo networkInfo;

           for(Network mNetwork : networks)
           {
               networkInfo = connectivityManager.getNetworkInfo(mNetwork);

               if(networkInfo.getState().equals(NetworkInfo.State.CONNECTED))
               {
                   return true;
               }
           }
       }

       //if user's os older then lollipop:
       else
       {
           //getAllNetworkInfo method work for only before API 19:
           NetworkInfo[] info = connectivityManager.getAllNetworkInfo();

           if(info != null)
           {
               for(NetworkInfo anInfo : info)
               {
                   if(anInfo.getState() == NetworkInfo.State.CONNECTED)
                   {
                       return true;
                   }
               }
           }
       }

       return false;
   }
}
