How can you ensure the preservation of the entire transition history in a navigation system?

To save the entire navigation history in an Android navigation system, you can use the following approaches:

• Using Fragment back stack — add transactions to the back stack during navigation so that the user can return to previous screens.

• Navigation Component — a modern tool from Google that automatically manages the navigation stack and allows saving the transition history.

• Custom navigation stack — implement a data structure (e.g., stack or list) to manually store information about each transition.

• Saving state in ViewModel or database — for restoring history after the app restarts.

Example of adding a fragment to the back stack:

supportFragmentManager.beginTransaction()
    .replace(R.id.container, newFragment)
    .addToBackStack(null) // adds the transaction to the back stack
    .commit()

Thus, when the "Back" button is pressed, the user will return to the previous screen, preserving the transition history.
