The Survey Android App is a coding challenge project designed to showcase my expertise in Android development. The application demonstrates the ability to load a questionnaire from the network, and allow users to answer questions, and submit their responses. The primary goal is to create a seamless and intuitive survey-taking experience for users.

The Survey App employs the Clean Architecture, which is structured into three main layers:
The data layer encapsulates the details of data sources and persistence, shielding the internal layers. It is responsible for retrieving and storing data through a defined repository.
The domain layer defines the core elements of the software, independent of specific application layers. It includes business models, rules, entities, and use cases. This layer is crucial as it houses the business logic of our application, managing specific operational rules without knowledge from outer layers. In the domain layer, specific abstract use cases are defined, each with a single responsibility. These use cases encapsulate the business logic of the application, providing a clear separation from the outer layers. They are designed to be versatile and can be utilized across various sections of the application.
The presentation layer acts as the application's user interface design, involving user interaction and data presentation. Sportscaster follows the Unidirectional Data Flow (UDF) pattern, also known as State Hoisting. This architectural pattern ensures a uni-directional stream of information, where the state descends and the events ascend.
Encapsulates Android resources (fonts, animations, string values) for clean separation, enhancing maintainability and reusability.
Centralizes Jetpack Compose UI components and an app-specific design system for consistent UI across the app, simplifying component creation.
Manages navigation events using NavController, providing a clean structure and decoupling navigation concerns from other app parts.
Handles network data fetching logic, ensuring clean separation for easy modification or extension without affecting other app parts.
Bridges core-network and core-database etc .. , abstracting data retrieval intricacies. Ensures the caller remains agnostic to data origin for a clean, modular architecture.
Shapes high-level app functionality, exposing well-defined, abstract use cases with single responsibilities. Enables seamless integration across various app sections, fostering a modular architecture.
A module housing extension functions, utility classes, and constants for common tasks, providing reusable components across various core and feature modules.
