Part 1: Main Activity

The Main activity is responsible for the loading and displaying the different sources available at NewsAPI. The requirements are as follows (Figure 1):

1. Upon loading the Main Activity, the app should connect to the Sources NewsAPI api to retrieve the JSON list of the sources provided by the NewsAPI.
   1. Create a Source class containing variables: id and name, which should be populated from the retrieved JSON.
   2. The app should use a child thread (or AsyncTask) to perform data retrieval and data parsing. The parsed JSON should return a list of Source objects. The list of news sources should be then returned to the Main Thread to be displayed.
   3. Display a Progress Bar during the download and parsing of the JSON as indicated in Figure 1(a).
2. The Source items should be displayed in a ListView. See Figure 1(b).
3. Upon clicking a list item it should open the News Activity, you should also pass the news source Source object to the News Activity.
