Android realtime messaging app written in Kotlin that features user login/registration and the ability to add friends. Realtime messaging utilizes a WebSocket when app is in the foreground and Firebase Cloud Messaging when in the background.

- Tinder/Scarlet: A Retrofit inspired WebSocket client for Kotlin, Java, and Android
- Firebase Cloud Messaging: A cross-platform messaging solution that lets you reliably deliver messages at no cost
- Room Persistence Library: An abstraction layer over SQLite to allow for more robust database access
- Navigation Component: A framework for navigating between 'destinations' within an Android application
- Retrofit: A type-safe HTTP client for Android and Java
- RxJava: Reactive Extensions for the JVM
- Dagger2: A fast dependency injector for Android and Java
Testing libraries include:
- Mockito: Mocking framework for unit tests in Java
- Roboelectric: Brings fast and reliable unit tests to Android
- Espresso: Write concise, beautiful, and reliable Android UI tests.
