The process for retrieving data from an API call and passing it to a ViewModel in Android Studio can be broken down into the following steps:
Step 1: Create an API interface Create an interface that defines the API endpoints and the parameters necessary for each endpoint.
Step 2: Set up Retrofit Retrofit is a type-safe HTTP client for Android that makes it easy to consume RESTful web services. Include Retrofit dependencies in the build.gradle file and initialize Retrofit in the Application class.
Step 3: Make the API call Using the API interface created in step 1, make the API call in the ViewModel using Retrofit.
Step 4: Parse the response Parse the response from the API call using Gson or another JSON parsing library.
Step 5: Store the data in the ViewModel Store the parsed data in the ViewModel to make it available to the UI.
Step 6: Observe the ViewModel in the UI Observe the ViewModel in the UI to update the UI with the retrieved data.
By following these steps, you can successfully retrieve data from an API call and pass it to a ViewModel in Android Studio.
