Architectures

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 🔑

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.
