What method should be overridden to manage back navigation in an Android Activity?

To effectively manage back navigation in an Android Activity, the method that should be overridden is onBackPressed(). This method is part of the Activity class and is invoked when the user presses the back button on their device. By overriding this method, developers can customize the behavior that occurs when the back button is pressed, whether that means navigating to the previous screen, closing the activity, or implementing specific logic to determine how to handle the back press.

For example, within the overridden onBackPressed() method, you can check the current state of your application, such as whether a dialog is open or if there's any data that needs to be saved before exiting the activity. This level of control allows for a tailored user experience in response to back navigation actions.

In contrast, the other options do not correspond to default methods provided by the Android framework for handling back navigation. Methods like onBackNavigation(), onBackAction(), and onNavigateBack() are not recognized by the Android Activity lifecycle and will not be invoked automatically by the system when the back button is pressed. Therefore, overriding onBackPressed() is the appropriate choice for handling this functionality directly within an Android application.
