Question

Ok I kinda got stucked on the basics.I have a method in class that shows a notification in the notification bar. I tried to make it static but if I make it static,some functions won’t work.

So if I have the following function in x.class,how can I access it from y.class? Because I tried with static,and with objects,but all failed.

 void notify(String i) {

        String ns = Context.NOTIFICATION_SERVICE;
        NotificationManager mNotificationManager = (NotificationManager) getSystemService(ns);


        int icon = R.drawable.icon;        // icon from resources
        CharSequence tickerText = "gogu la telefon";              // ticker-text
        long when = System.currentTimeMillis();         // notification time
        Context context = getApplicationContext();      // application Context
        CharSequence contentTitle = "My notification";  // message title
        CharSequence contentText = "Hello World!";      // message text



        Intent notificationIntent = new Intent(this, MilkyWaySearcherActivity.class);
        PendingIntent contentIntent = PendingIntent.getActivity(this, 0, notificationIntent, 0);

        // the next two lines initialize the Notification, using the configurations above
        Notification notification = new Notification(icon, tickerText, when);
        notification.setLatestEventInfo(context, contentTitle, contentText, contentIntent);
        notification.ledARGB = 0xff00ff00;
        notification.ledOnMS = 300;
        notification.ledOffMS = 1000;
        notification.flags |= Notification.FLAG_SHOW_LIGHTS;

        mNotificationManager.notify(BIND_AUTO_CREATE, notification);
    }

You either need to create an instance, or make the method static.

Static methods cannot access instance methods unless there’s an instance.

Static methods cannot use the this keyword, because there is no instance to refer to.

In this case, it might be enough to pass in a replacement for where you use this.
