Android How to Program, 3/e

7.7 Class MainActivity

Class MainActivity defines the app’s user interface, the logic for interacting with the OpenWeatherMap.org daily forecast web service and the logic for processing the JSON response from the web service. The nested AsyncTask subclass GetWeatherTask performs the web service request in a separate thread (Section 7.7.5). MainActivity does not require a menu in this app, so we removed the methods onCreateOptionsMenu and onOptionsItemSelected from the autogenerated code.
