Weather Application

An android Weather Application that uses android MVVM clean architecture using Kotlin

How to enable the API https://api.openweathermap.org/ to your application

• Since we cannot expose the api token to our github repo, I implemented a apikey.properties file which will hold the api key and this copy is only available to your local machine.
• Create a file from the root project named apikey.properties
• After creating apikey.properties, please put variable and value of your openweathermap api and name the variable this OPEN_WEATHER_API_KEY = """
• Clean project and build. If you encounter compilation error, it means that you didn't created the property file or variable name is incorrect.
• How did I load the property file can be seen in app/build.gradle
• You can access the api key by accessing BuildConfig.OPEN_WEATHER_API_KEY
