RexWeather Documentation

RexWeather is a sample Android project designed to demonstrate the integration of two key libraries:

1. Retrofit (by Square): A REST client that turns a REST API into a Java interface using annotations. It handles the generation of the implementation for HTTP requests (e.g., converting GET /users/{userId}/posts into a method call).
2. RxJava (by Netflix): A library for composing asynchronous and event-based programs. It allows for building declarative pipelines that handle threading, synchronization, and error handling, preventing 'callback spaghetti' by managing complex sequences of events (like location changes triggering multiple web service calls) in a single stream.

A 7-day forecast can be retrieved using the OpenWeatherMap forecast/daily endpoint. Parameters include lat, lon, mode (e.g., json), units, and cnt (to specify the number of days, e.g., 7).

Example Request URL: http://api.openweathermap.org/data/2.5/forecast/daily?lat=-31.9522&lon=115.8589&mode=json&units=metric&cnt=7

Current weather data can be retrieved by making a GET request to the OpenWeatherMap weather endpoint. The request requires latitude (lat), longitude (lon), and optionally units (e.g., metric).

Example Request URL: http://api.openweathermap.org/data/2.5/weather?lat=-31.9522&lon=115.8589&units=metric
