Lab 12: Weather Viewer App ( Due 08 Apr 2013 )

This app allows the user to obtain the city's current weather conditions or its five-day weather forecast. The app uses WeatherBug web services. The Android's JsonReader is used to read the weather data returned by the WeatherBug web services. The weather data is in JSON (JavaScript Object Notation) format.

Using the AddNewCity option in the action bar new cities can be added. The user can switch from current conditions to five-day forecast using the action bar's tabbed navigation. A list of cities is displayed as a ListFragment that contains a ListView.

The app has a companion app widget that can be installed on your home screen and your preferred city's current weather conditions can be viewed.

With this app you will be learning the following technologies on the Android platform:

• Use WeatherBug web services to get the current conditions and five-day forecast for a specified city and process that data using an Android JsonReader.
• Use Fragments to create reusable components and make better use of the screen real estate in a tablet app.
• Implement tabbed navigation using ActionBar.
• Create a companion app widget that can be installed on the user's home screen.
• Broadcast changes of the app's preferred city to the companion app widget.

Realize that the instructions in the book is for an older version of eclipse and android api. One of the challenges that you will have to face is to map the older features mentioned in the instructions to the newer features of both eclipse and the android platform.
