How can you perform pre-configuration of a task before starting the main application?

In Android, to perform pre-configuration of a task before launching the main application, you can use the Application class and its onCreate() method. This method is called at the start of the application before any activities are created, making it convenient to initialize necessary components, settings, or services.

Example:

class MyApp : Application() {
    override fun onCreate() {
        super.onCreate()
        // Initialize settings, libraries, logging
    }
}

You can also use a ContentProvider for initialization, as it is created earlier than Application, but this is less common.

If you need to perform a task immediately before launching a specific Activity, you can use a SplashScreen or ViewModel to prepare data.
