Short Overview on what App does:

Clima weather app is a simple weather forecast app that uses api to get json the openweather.org website. The openweather website is a weather forecast website and allows user to integrate weather apis into your app. These api requries to send parameters to get the weather data which is usually in json format. The data can be fetched using api’s given by the openwaeather website itself by which we can send parameters to get weather data. However, to get access to api. you have to sign in and request for app_key to openweather.org website.

In my case, i used longitude and latitude and city name as parameter for api to get the result from the open weather database. The app displays current temperature and weather status in image as weather forecast for specifice city. When the app starts, user will get a toast message “”fetching location” which get your current longitude and latitude data and send those params to get weather for your current area.
