Cannot find symbol NOTIFICATION_SERVICE?

Question

package com.test.app;
import android.app.Notification;
import android.app.NotificationManager;
import android.app.PendingIntent;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;

public class runOnBoot extends BroadcastReceiver{

   @Override
   public void onReceive(Context context, Intent intent) {

          NotificationManager nm = (NotificationManager)getSystemService(NOTIFICATION_SERVICE);
   }
}

When I try to build the package, it says

compile:
    [javac] Compiling 2 source files to /home/mrburns/Desktop/myapp/bin/classes
    [javac] /home/mrburns/Desktop/myapp/src/com/test/app/runOnBoot.java:14: cannot find symbol
    [javac] symbol  : variable NOTIFICATION_SERVICE

Answer 1

I found calling this way works:

NotificationManager nm = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);

Supererogatory

Answer 2

This should be Context.NOTIFICATION_SERVICE:

NotificationManager nm = (NotificationManager)getSystemService(Context.NOTIFICATION_SERVICE);

I see that is answer is currently being downvoted while it wasn't before. As it has been written in 2011, I suspect that some API updates make it deprecated though I didn't have time to check. – Loquat

Answer 3

For those using Kotlin, the following line performs the same functionality as the other answers here.

val nm = context?.getSystemService(NOTIFICATION_SERVICE) as NotificationManager

this solution has helped me. I needed to add the context. – Eringo

Answer 4

NotificationManager mNotifyMgr = (NotificationManager)context.getSystemService(Context.NOTIFICATION_SERVICE);

In addition to your code please add some text to explain why your answer works or how it is different from previous answers. – Lejeune

Answer 5

This should be

notificationManager = (NotificationManager) getSystemService(android.content.Context.NOTIFICATION_SERVICE);

Answer 6

You should better try this

 NotificationManager nm = (NotificationManager)getSystemService(getApplicationContext().NOTIFICATION_SERVICE);

NOTIFICATION_SERVICE is a public static final String. You do not need any instance of Context to use it. – Loquat

it can be accessed in both ways :) If you are displaying the notification in Any web Service not in activity then you dont have the Context with you :) – Cauthen

You don't need any instance of Context. You statically call it from the class Context. – Loquat
