1 | ### Weather
2 | This is a demo app built for teaching concepts. It shows the weather for various cities by zip.
3 |
4 | ### Usage
5 |
6 | 1. Add a zip code.
7 | 2. It reverse geocodes the lat/long and location name from the zip code.
8 | 3. Uses the [darksky.net](https://darksky.net) weather API to fetch current forecast data.
9 | 4. Stores all of the data on device, persistent across launches.
10 | 5. Weather forecast data is cached, but refreshed by the repository on launch.
11 |
12 | ### Libraries + Concepts
13 | * *Architectural Patterns* - Model-View-ViewModel, Repository, Dependency Injection.
14 | * *Android GeoCoder API* - For reverse geocoding the zip code.
15 | * *Architecture Compnents* - LiveData, Room, ViewModel, Navigation Architecture Components.
16 |
17 | ### Screenshots
18 | .
19 |
20 | ### Status
21 | This is a work in progress, still adding tests and cleaning up organization.
22 |
23 | ### What this app is and isn't
24 |
25 | #### Features
26 | This app is meant for educational purposes as a reference to blog posts and other teachings.
27 | It is not meant to be a feature complete product.
28 |
29 | #### Best Practices
30 | The code, while is meant to be written and tested with best practices, may not always reflect the latest.
31 | For example, this project makes use of Anko and an early version of Coroutines that may not reflect current best practices.
32 |
33 | #### Collaboration
34 | Since this app is a personal playground used for teaching purposes, I would prefer not to accept any PRs or Issues at this time. Though suggestions are always welcome. You can reach out to me on Twitter @[emmax](https://twitter.com/emmax).
