contact | integrated Android Architecture Components as the ViewModel

contact is a Kotlin library. contact has no bugs, it has no vulnerabilities and it has low support. You can download it from GitHub.

In this project, I've integrated Android Architecture Components as the ViewModel layer to separate the business logic. I've also demonstrated how to unit test ViewModel and Repository. The DataSource is an interface that if we want to put it into real production environment we can quickly change the DataSource, so it is scalable to add network or local database implementations. The UT cases are extremely limited, due the lack of time to consider all the details, but still I've added as many as I can to get the best result.
