Implementing the Observer
</pre>
== Implementing the Observer Observer ==
Now that the conversion result is contained within a LiveData instance, the next step is to configure an observer within the UI controller which, in this example, is the MainFragment class. Locate the MainFragment.java class (app -> java -> <package name> -> MainFragment), double-click on it to load it into the editor and modify the onActivityCreated() method to create a new Observer instance named resultObserver:
                mViewModel.setAmount(Float.valueOf(
dollarText.getText().toString()));
                resultText.setText(mViewModel.getResult().toString());
            } else {
                resultText.setText("No Value");
