Updating Sunshine to use AsyncTaskLoader

Let's update Sunshine, replacing the FetchWeatherTask with an AsyncTaskLoader.
SOLUTION:
  • Have MainActivity implement the loader callbacks
  • Create a loader ID
  • Fill out the loader callbacks using the code from FetchWeatherQuery
  • Call initLoader in onCreate (whether or not the loader already exists)
  • Restart the loader if refresh is triggered from the menu
