  2. The Reason for Creating the Application • Everyone occasionally gets calls from unknown numbers. • Sometimes need to know which carrier’s network a number is on. • Knowing whether the number is a land line or a cellular signal can be helpful. • Knowing where a number originated geographically can help identify calls.

  3. What the Application Does • Takes a 10 digit phone number as input from the user. • Finds information about the number including: • The number’s carrier network • The numbers location (landline) or place of registration (cellular) • The ZIP code native to the phones location • The country the number is from • Finds a list of major cities in the area code to give the user an idea of the numbers geographic area.

  4. How the Application Works: The Big Picture • Takes a 10 digit numeric phone number as input • Performs two concurrent http get requests • One request gets information related to the number from the website http://www.melissadata.com/lookups/phonelocation. • The other request get a list of major cities located in the number’s area code from the website http://www.allareacodes.com/reverse-phone-directory/. • A GUI is updated to display the information.

  5. How the Application Works: The Details • The programs main Activity is called. • The Activity implements the OnClickListener interface. • The “Find Info” button is added to the listener.

  6. How the Application Works: The Details • When the “Find Info” button is pressed, the onClick method is called. • The onClick method creates two threads that run the information finding tasks concurrently.

  7. How the Application Works: The Details • The InfoFinderTask and CityFinderTask classes implement the Runnable and HttpCallback interfaces. • Their constructors take a parent Activity and a GUI handler as parameters. • Both have run, onResponse, and onError methods.

  8. How the Application Works: The Details • The city finder and info finder tasks perform http get requests in their run methods. • Because the tasks themselves implement HttpCallback, the task objects are passed into the respective get requests. • After the request is performed, the onResponse method of each task is called. • The GUI is updated with the information accordingly in the onResponse methods using the handler.
