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

  • Using the 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 transition history.

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

  • Save state in ViewModel or database — to restore history after restarting the app.

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()

This way, when pressing the "Back" button, the user will return to the previous screen, preserving the transition history.
