Image Fetcher is a sample Android application, built to demonstrate use of Modern Android development tools.
It simply searches images. You can choose image categories from different sections or you can enter a search string to find the right image for you. It loads searched Images data from Imgur API and displays in a Grid format. The user can tap on the image which opens the next screen where users can see total likes, dislikes, scores, and descriptions associated with that image. The application supports the lazy loading of images so users can have a seamless data loading experience. Users can also apply filters to include viral and non-viral images. Implemented Lifecycle aware view holder for image list which respects the lifecycle of row's view components.

This app uses MVVM (Model View View-Model) architecture.
The philosophy behind this architecture is to enable separation of concerns and ultimately a very modular application. This architecture was chosen because it provides the opportunity to separate concerns and implement "SOLID" principles which makes the application more robust and the code base scalable and maintainable.
This due separation of moving parts makes the app more testable with unit tests.
