I can’t solve a notification line

Question

The error is on the line: notification.setLatestEventInfo(context, contentTitle, contentText, contentIntent);. I couldn’t fix it. Any change I make makes a mistake.

// Define Notification's message and Intent
    CharSequence contentTitle = context.getString(R.string.notif_title);
    CharSequence contentText = String.format(context.getString(R.string.notif_text),
            iptext);

    Intent notificationIntent = new Intent(context, FTP_Start_Stop.class);
    notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP
            | Intent.FLAG_ACTIVITY_SINGLE_TOP);
    PendingIntent contentIntent = PendingIntent.getActivity(context, 0,
            notificationIntent, 0);
    notification.setLatestEventInfo(context, contentTitle, contentText, contentIntent);
    notification.flags |= Notification.FLAG_ONGOING_EVENT;
