Android Architecture

Stateful Android features are managed by standardizing project architecture with a TEA-based pattern. This provides a lifecycle-aware Store using immutable State and pure Reducers to enforce predictable state across large codebases.

The TEA pattern for Android state management models UI logic using State, Commands, and SideEffects. It processes Actions through pure Reducers and handles SideEffects asynchronously via dedicated EffectHandlers.

Android project modularization with Jetpack Compose is structured using a BaseStoreViewModel and ViewStateMapper. This maps immutable State to UI-driven screens within container-based fragments or activities to enforce composition.

This Android architecture works with both Views and Jetpack Compose. It establishes a defined Store-driven architecture with ViewState mapping to support predictable UI rendering across both UI toolkits.

Side effects in an Android MVVM architecture are handled using dedicated EffectHandlers. The Store dispatches Commands processed by pure Reducers, routing SideEffects asynchronously to keep state transitions predictable.

A Store-based architecture should be used when building Android apps with stateful features at a large team scale. It enforces lifecycle-aware state management and modularization to manage multi-file interdependencies.
