What are the steps for building an MVVM framework in Android?

The steps to set up an MVVM framework are as follows:

1. Add dependencies: Add library dependencies for the MVVM framework, such as LiveData and ViewModel, in the build.gradle file of the project.
2. Create a ViewModel: Develop a class that inherits from ViewModel to manage data and business logic.
3. Create a data model: Establish a data model class that is used to store data, which can be a POJO class or an entity class.
4. Create a Repository: Set up a Repository class to serve as the origin for retrieving and processing data.
5. Develop the UI layer: Create UI interfaces such as Activities or Fragments, and bind them with ViewModels.
6. Set up data binding: Use a data binding library (such as DataBinding library) to connect data with UI elements, enabling bidirectional binding.
7. Monitor the data: observe the changes in the LiveData object in the ViewModel at the UI layer to update the UI interface.
8. Manage user interactions: handle user input events in the UI layer and process corresponding business logic through the ViewModel.
9. Render UI: Updating the data from the ViewModel to the UI interface in order to display the latest data.
10. Testing and debugging: Conduct unit tests and integration tests to ensure the stability and functionality of the framework.

The above are the general steps to build an MVVM framework, with specific implementations varying depending on framework choices and project requirements.
