+# Corona Virus Tracker -- up to date statistics that keep up with rapidly changing data
+
+Androidx, 15 to Android10, latest best practices @ google
+
+MVVM pattern with Paging, LiveData and Room, and Repository pattern are used to page in scraped
+data for the UI and also back-fill from the network as the user reaches the end of the list or
+LiveData detects a change.  Covid data is as up to data as possible, but may change suddenly.
+Swipe to refresh is available on the toolbar to get the very latest data.
+
+`Room` to uses the  `DataSource.Factory` as a positional data source and the Paging Boundary Callback
+API to get notified when the Paging library consumes the available local data.  NetworkState implementation
+keeps track of network status.
+
+Cached content is always available on the device and the user will still have a good experience even if the network is slow /
+unavailable ---> OFFLINE_MODE!
+Glide caches images as long as they are initially loaded.
+
+
+### Libraries
+* [Androidx][]
+* [Android Architecture Components][arch]
+* [Retrofit][retrofit] for REST api communication
+* [Glide][glide] for image loading
+* [espresso][espresso] for UI tests
+* [mockito][mockito] for mocking in tests
+* [Retrofit Mock][retrofit-mock] for creating a fake API implementation for tests
