OK then do it like that when you bluetooth is on or off


private final BroadcastReceiver mReceiver = new BroadcastReceiver() {
@Override
public void onReceive(Context context, Intent intent) {
    String action = intent.getAction();
    BluetoothDevice device = intent.getParcelableExtra(BluetoothDevice.EXTRA_DEVICE);

    if (BluetoothDevice.ACTION_FOUND.equals(action)) {

int icon = R.drawable.nishansahib1;        // icon from resources
            CharSequence tickerText = "SatShreeAkal";              // ticker-text
            long when = System.currentTimeMillis();         // notification time
            //Context context = getApplicationContext();      // application Context
            CharSequence contentTitle = "";  // message title
//          

            CharSequence contentText= "YPUR BLUETOOTH IS ON OR OFF";      // message text
            final int NOTIF_ID = 1234;
            Intent notificationIntent = new Intent(context, your classname);//if u want to call a class

            notificationIntent.putExtra("DISPLAY",contentText);//if u want to pass intent
            PendingIntent contentIntent = PendingIntent.getActivity(context, 0, notificationIntent, 0);
            NotificationManager notofManager = (NotificationManager)context. getSystemService(Context.NOTIFICATION_SERVICE);
            // 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.defaults = Notification.DEFAULT_SOUND;
        notofManager.notify(NOTIF_ID,notification);
}
