        if (greetingTask != null){
            greetingTask.cancel(true);
        }
    }
    public void greetHello(){
        cancelGreetingTaskIfRunning();

        greetingTask = new GreetingGeneratorTask("Hello", new GreetingGeneratorTask.GreetingTaskListener() {
            @Override
            public void onGreetingGenerated(String greetingText) {
                if (isViewAttached()) {
