Sunshine with Architecture Components

About

This app is for the Build an App with Architecture Components Codelab.

Starting Classes

Below is a description of the different packages and classes in the starting app code.

data package

Contains all classes related to local and network app data.

data.network package

All classes related to fetching data from the network.

  • The network fetching and parsing functions are all written for you.
  • You will not modify the NetworkUtils, OpenWeatherJsonParser and WeatherResponse classes.
  • WeatherNetworkDataSource manages everything to do with the network. It's a singleton. It contains:
    • scheduleRecurringFetchWeatherSync() - Makes a repeating JobService using FirebaseJobDispatcher. This repeating job will eventually sync weather information in the background.
    • startFetchWeatherService() - IntentService for doing an immediate fetch of weather data.
    • fetchWeather() - Actually gets weather forecast data. This method uses the JSON parsing classes and network classes to make the fetch. It currently doesn't do anything with the fetched weather data.
data.database package

All classes related to caching the data locally (it's pretty empty right now).

  • WeatherEntry - A simple Java object representing one day of weather.

ui package

All activities and adapters - anything to do with display.

ui.detail package
  • DetailActivity - Activity for a single day of forecast.
ui.list package
  • MainActivty - Activity for a list of WeatherEntry forecasts.
  • ForecastAdapter - RecyclerView.Adapter for displaying the list of WeatherEntry forecasts.

utilities package

  • You will not modify SunshineDateUtils or SunshineWeatherUtils.
  • SunshineDateUtils - Utility methods for normalizing dates across time zones; this helps us to "round" to the nearest date, so that when you store a date in the database, it always refers to that date at 12:00am, GMT.
  • SunshineWeatherUtils - Utility methods related to displaying the weather, such as picking the right image resource to show a cloudy sky or rain.

AppExectuors class

This class provides a global executor pool. You can learn more about thread pools here. In short, this class provides an easy and efficient way to run code off of the main thread.
