• This is weather android app which uses worldweatheronline.com as data provider
• v1.0.0

• ./gradlew clean build
• and don't forget to setup your sdk.dir (via local.properties or direct specification)

The whole design of my app is based on Dependency Injections and EventBus concepts. I wanted to split all classes out from each other onto independent components.

Interaction with weather web-service is based on fetching forecast by latitude and longitude. I use shared preferences as a cache for forecast responses and update this cache in two cases:

1. user refreshed the list manually by pull-to-refresh action on the list of data
2. time of response is expired (it's 24 hours) and in the next scrolling action - application will try to fetch new data for this location

I used a lot of 3rd libraries and the main reason why I did it, just to speed up development process.

• rxjava - don't like to hassle with AsyncTask
• retrofit - quick bootstrap of any http webservice stub
• ormlite - quick bootstrap for database
• otto - eventbus
• dagger2 - DI
• com.etsy.android.grid - Staggered GridView for weather dashboard
• timber - very customizable logger for android

DI, EventBus, Observer, Builder

Applications consists of two screens:

1. main screen with weather dashboard
2. settings activity where the user can specify Temperature Units (Celcius or Fahrenheit)
3. and Debug activity to show how to override eventbus

Small clarification: To refresh weathers list - just pull down (I used SwipeRefreshLayout from support library)

To run & debug unit-tests in IDE you need to use Android Studio 1.4
