Android Interface Description Language (AIDL)​

AIDL (Android Interface Definition Language) allows you to define the programming interface that both the client and service agree upon in order to communicate with each other using interprocess communication (IPC). On Android, one process cannot normally access the memory of another process. So to talk, they need to decompose their objects into primitives that the operating system can understand, and marshall the objects across that boundary for you. The code to do that marshalling is tedious to write, so Android handles it for you with AIDL.

Repository Pattern​

Why the Repository Pattern ?​

  • decouples the application from the data sources
  • provides data from multiple sources (DB, API) without clients being concerned about this
  • isolates the data layer
  • single place, centralized, consistent access to data
  • testable business logic via Unit Tests
  • easily add new sources

HILT​

Hilt provides a standard way to incorporate Dagger dependency injection into an Android application.

The goals of Hilt are:

  • To simplify Dagger-related infrastructure for Android apps.
  • To create a standard set of components and scopes to ease setup, readability/understanding, and code sharing between apps.
  • To provide an easy way to provision different bindings to various build types (e.g. testing, debug, or release).
