Wear for Android is not showing

I have a problem. My Android clothes emulator doesn't show notification. Here is my mobile code:

private void notifyToWear() {
        NotificationCompat.WearableExtender wearableExtender = new NotificationCompat.WearableExtender()
                .setHintShowBackgroundOnly(true);

        NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
                .setSmallIcon(R.drawable.ic_launcher)
                .setContentTitle("Request text")
                .setContentText("Speak something then your phone will search it.")
                .extend(wearableExtender);

        NotificationManagerCompat notificationManager = NotificationManagerCompat.from(this);
        notificationManager.notify(0, notificationBuilder.build());
    }

      

        
        
        
      

    

I call it when the MainActivity button is clicked. On my phone, it shows a notification, but not on the Android wearable emulator. Notes: + I connected between android phone and android wear emualtor. I tested with a sample card in the Android Wear App. He works.

Thank.

- Update - The code executes the click button:

(findViewById(R.id.btn_request_text)).setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                Toast.makeText(MyActivity.this, "Call request", Toast.LENGTH_SHORT).show();
                notifyToWear();
            }
        });

      

        
        
        
      

    

When I click the "Toast is show" button.

--- Update --- I am also running ElizaChat and RecipeAssistant in Wear Sample. But it doesn't work either.
