MovieHunt

MovieHunt is a sample Android project using The Movie DB API based on MVVM architecture. It showcases the latest Android tech stacks with well-designed architecture and best practices.

> The new v2 re-design is available. πŸŽ‰ Check it out now!

MovieHunt

Features

  • 100% Kotlin
  • MVVM architecture
  • Reactive pattern
  • Android architecture components and Jetpack libraries
  • Single activity pattern
  • Dependency injection
  • CI support (Upcoming)
  • Testing (Upcoming)

Tech Stacks

  • Retrofit + OkHttp - RESTful API and networking client.
  • Koin - Dependency injection.
  • Android Architecture Components - A collections of libraries that help you design rebust, testable and maintainable apps.
    • Room - Local persistence database.
    • Paging - Pagination loading for RecyclerView.
    • ViewModel - UI related data holder, lifecycle aware.
    • LiveData - Observable data holder that notify views when underlying data changes.
    • Data Binding - Declarative way to bind data to UI layout.
    • Navigation component - Fragment routing handler. (Upcoming)
    • WorkManager - Tasks scheduler in background jobs. (Upcoming)
  • ~RxJava - Asynchronous programming with observable streams.~ Replaced by Coroutine + Flow.
  • (Upcoming) Flow Stream of value that returns from suspend function.
  • (Implementing) Coroutine Concurrency design pattern for asynchronous programming.
  • ~Epoxy - Simplified way to build complex layout in RecyclerView.~ Replaced by Jetpack Compose.
  • Coil - Image loading.
  • Timber - Extensible API for logging.
  • (Implementing) Jetpack Compose - Declarative and simplified way for UI development.

Architectures

MVVM

We follow Google recommended Guide to app architecture to structure our architecture based on MVVM, reactive UI using LiveData / RxJava observables and data binding.

  • View: Activity/Fragment with UI-specific logics only.
  • ViewModel: It keeps the logic away from View layer, provides data streams for UI and handle user interactions.
  • Model: Repository pattern, data layers that provide interface to manipulate data from both the local and remote data sources. The local data sources will serve as single source of truth.

API Key πŸ”‘

You will need to provide developer key to fetch the data from TMDB API. * Generate a new key (v3 auth) from here. Copy the key and go back to Android project. * Create a new kotlin file

ApiKey.kt
in path
./buildSrc/src/main/kotlin/
. * Define a constant
TMDB_API_KEY
with the double quotes, it looks like
const val TMDB_API_KEY = "\"90c05******************655\""
  • Add the key to build config in
    ./buildSrc/src/main/kotlin/Config.kt
    :
defaultConfig {
    ...
    buildConfigField("String", "TMDB_API_KEY", TMDB_API_KEY)
    ...
}
  • Perform gradle sync.

NOTE: It's important to keep the double quotes for this value, since it's used as String type build config fields, the field name in quotes, the field value in escaped quotes additionally. If you're missing the double quotes, it will build fail.
