This app was made for training purposes. It was created to learn Kotlin language and some of popular Android frameworks and libraries.
Due to its training purpose application could evolve in future.
Application is basically a simple REST client for TMDb API.
Before first launch, a special API key should be provided. It can be placed in a file key.txt in the project's main directory. During building process it will be copied in the app's resources.
The key is private, so it should not be shared publicly. More information about the key and how to receive it under link: TMDb developers
