Collecting weather forecast data

Now that our application's user interface is completed, we can proceed to implement the logic to store the user's location while fetching weather data from the RESTful web service. This implementation could be organized in the following steps:

  1. Update the Preset class to store the user's location.

  2. Handle voice recognition results when the user clicks on the weather_status TextView parameter.

  3. Add a new scheduled thread that fetches weather data and updates the user interface using the onWeatherChanged() callback.

We start updating the Preset class and realizing it with the following steps:

  1. Add, at the top of the class, the highlighted declaration used as a key to store and retrieve the location set by users:

    private static final String CURRENT_PRESET = "__CURRENT__";
private static final String CURRENT_LOCATION = "__LOCATION__";

  2. At the bottom of the class, add the following setter to store the given location:

    public static void setLocation(Context ctx, String name...
