Mavericks
Mavericks is an opinionated Android state management framework that structures screen-level state as a single immutable object and processes user actions through a unidirectional data flow. It enforces state immutability to prevent unintended mutations and simplify debugging, while managing state subscriptions and cleanup based on Android lifecycle events to prevent memory leaks.
The framework uses a ViewModel-driven architecture where business logic and state management are encapsulated in ViewModels that survive configuration changes. User actions are handled through dedicated intent objects that update state in a controlled, predictable manner, and state changes are exposed reactively via LiveData or RxJava observables to ensure the UI layer always reflects the latest data.
Mavericks enables building reactive Android screens of any complexity without increasing debugging difficulty, as the entire UI state is defined as a single immutable object that automatically updates the UI through reactive subscriptions. The framework's documentation covers installation and setup for integrating this state management approach into Android applications.
