        ConnectivityManager connectionService =
            (ConnectivityManager) getSystemService(CONNECTIVITY_SERVICE);
        if (connectionService.getActiveNetworkInfo().isConnectedOrConnecting()) {
            // Device is online
        }

// Network is connected or not 
public boolean isConnected()
{
    ConnectivityManager connectivity = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
      if(connectivity != null)
      {
          NetworkInfo[] info = connectivity.getAllNetworkInfo();
          if (info != null)
              for (int i = 0; i < info.length; i++)
                  if (info[i].getState() == NetworkInfo.State.CONNECTED)
                  {
                      Log.d("LOG","Network is Available");
                      return true;
                  }

      }
      return false;

Use the following function inorder to check the internet connction:

public boolean isOnline()
    {

         ConnectivityManager cm = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);
         NetworkInfo ni = cm.getActiveNetworkInfo();
         boolean result = false;
         if(ni != null )
         {
             if(  ni.getState() == NetworkInfo.State.CONNECTED )
             {
                 result = true;
             }
         }

         return result;

        }

check what isOnline() returns .If true then Internet is connected else Inernet is not connected . Hope this will help you..:)

  getSystemService(Context.CONNECTIVITY_SERVICE);
  NetworkInfo netInfo = cm.getActiveNetworkInfo();
  if (netInfo != null && netInfo.isConnectedOrConnecting()) {
     return true;
  }

}

if(temp==true){
