IntentService Error: No default Constructor

Question

I am a newbie to Android, and I am trying to use the IntentService but I get an error that it has no default constructor. I tried restarting the Android Studio it doesn't work.

package com.example.hitesh.kuchbhi;  import android.app.IntentService; import android.app.NotificationManager; import android.app.PendingIntent; import android.bluetooth.BluetoothAdapter; import android.content.Context; import android.content.Intent; import android.support.v4.app.TaskStackBuilder; import android.support.v7.app.NotificationCompat;  import java.util.TreeSet;  public class DisplayNotification extends IntentService {     public DisplayNotification(String name) {         super("DisplayNotification");     }      @Override     protected void onHandleIntent(Intent intent) {         // my code which even after deleting gives the same error     } 

log cat error

Just add a default constructor

public DisplayNotification() {     super("DisplayNotification"); } 

That means a constructor with no parameter
