public  void onMessageReceived(RemoteMessage remoteMessage){
    super.onMessageReceived(remoteMessage);
    getimage(remoteMessage.getNotification().getTitle(), remoteMessage.getNotification().getBody());

}
public void getimage(String title,String message){
    NotificationCompat.Builder builder=new NotificationCompat.Builder(this,"mynotification")
            .setContentTitle(title)
            .setSmallIcon(R.mipmap.ic_launcher_round)
            .setAutoCancel(true)
            .setContentText(message);


    NotificationManagerCompat manager =NotificationManagerCompat.from(this);
    manager.notify(999,builder.build());

}
}

Wo isliye kyuki url_value doesn't exist in your class. Maine bas ek example dikhaya hai. — Yash, Aug 20 '19 at 18:26
Haan I saw. It is because your R.mipmap.ic_launcher_round is also this icon. You can change it by creating a new drawable and setting it. — Yash, Aug 20 '19 at 18:43
Have you changed the icon? Instead of R.mipmap.ic_launcher_round and R.drawable.logo use the drawable you want to use. — Yash, Aug 20 '19 at 19:09
yaa i had changed and i had tried 10 different different icons — Egarage e, Aug 20 '19 at 19:10
Alright then add that both notification and manifest code in your question so I can see what's the issue. — Yash, Aug 20 '19 at 19:12

Make sure that in your AndroidManifest file, you've set the icon for Firebase notification like this:

    <meta-data
        android:name="com.google.firebase.messaging.default_notification_icon"
        android:resource="@drawable/myLogo" />
// Here, instead of myLogo you can put the drawable you want.

Setting small notification icon dynamically is not possible currently in Android, only large icon can be set this way. You need to store the drawables of the relevant small icons locally and use the appropriate one when building the notification. Sample:

 // URL value is your URL to the image
Bitmap mIcon1 = BitmapFactory.decodeStream(url_value.openConnection().getInputStream());
NotificationCompat.Builder builder=new NotificationCompat.Builder(this,"mynotification")
        .setContentTitle(title)
        .setSmallIcon(R.drawable.myLogo)
        .setLargeIcon(mIcon1)
        .setAutoCancel(true)
        .setContentText(message);

Instead of using URL, you can load the large icon from anywhere as a bitmap but not the small icon because setSmallIcon() which requires id to a locally stored resource as from it's definition:

/**
 * Set the small icon to use in the notification layouts.  Different classes of devices
 * may return different sizes.  See the UX guidelines for more information on how to
 * design these icons.
 *
 * @param icon A resource ID in the application's package of the drawable to use.
 */
public Builder setSmallIcon(int icon) {
    mNotification.icon = icon;
    return this;
}

When the app is in the background the launcher icon is used from the manifest (with the requisite Android tinting) for messages sent from the console.

Apparently you see the icon specified in the manifest for your application

Look here and here
