- A simple splash screen added in the start with application theme.
- Shimmer layout added for loading view while loading data from server
- Kotlin Coroutines is used for background operations with different dispatcher.
- Dagger Hilt is used for dependency injection.
- Navigation UI component was used for loading starting fragment and is scalable in future.
- Retrofit is used for networking.
- Gson and GsonConverterFactory is used for JSON parsing with retrofit.
- Retrofit cache interceptor is used for cache mechanism and offline support.
- Glide is used for image loading and caching.
- A custom designed parent-child adapter was implemented for the recyclerview as it can handle multiple type of layout managers (depending upon the type).

I had to use the retrofit cache interceptor for offline caching mechanism. Initially I tried working with Room DB for quite a while but unfortunately I couldn't get along with only one issue that I was facing almost from the beginning. I still couldn't fix it even finishing the whole task! So, this was the first challenging task. The work with the room DB is in another branch named "feature/caching-using-room-db", i will fix it when I get time.
Another one is UI testing. After worked the network testing and repository testing, when I moved to the UI testing I found it challenging enough. I have tried with less complex UI than the current one. To resolve this, I also tried mocking the FragmentBinding to access the child view ID but I couldn't succeed but I can check the immediate view hierarchy and test it. I needed some more research on it but as I have some deliverable form my office, I couldn't.
Adding gamification to the lessons so that people become more engaged to the course they are enrolling into. I have gone through some course's details page where both video player and information like course outline situated but when ever user scrolls down or go back from current page, the video gts hidden and stopped respectively but as of my perspective I would like watch what I was watching while traversing the whole application. From this idea a PiP (Picture in Picture) Mode will be a very good choice of features to improve Midnvalley app overall.
