        // Example of a common mistake: not disposing of subscriptions.
        
        // Subscribing to an Observable without proper disposal can lead 
        // to memory leaks in your application.
        
        Observable observable = Observable.create(emitter -> {
            emitter.onNext("Hello");
            emitter.onComplete();
        });

        Disposable disposable = observable.subscribe(
            item -> Log.d("TAG", "Received: " + item),
            Throwable::printStackTrace
        );

        // Common mistake: not disposing
        // Ideally, we should dispose of the `disposable` in onDestroy(), 
        // to prevent memory leaks.
        
        // In Android, utilize CompositeDisposable for managing multiple disposables.
        CompositeDisposable compositeDisposable = new CompositeDisposable();

        compositeDisposable.add(disposable);
        
        // In onDestroy()
        @Override
        protected void onDestroy() {
            super.onDestroy();
            compositeDisposable.clear(); // Clears all disposables
        }
