Could you explain what is meant by the term Target Fragment in the context of Android development?

In the context of Android development, the term Target Fragment usually refers to a fragment that is the recipient of a result or interaction from another fragment.

When one fragment launches another (for example, to get data or make a selection), it can set itself as the "target fragment" of the called fragment. This allows the called fragment to send a result back to the caller.

Example of usage:

// In the calling fragment
val fragment = SomeDialogFragment()
fragment.setTargetFragment(this, REQUEST_CODE)
fragment.show(parentFragmentManager, "dialog")

// In SomeDialogFragment upon completion
val target = targetFragment
if (target != null) {
    val intent = Intent()
    intent.putExtra("result", data)
    target.onActivityResult(targetRequestCode, Activity.RESULT_OK, intent)
}

Thus, Target Fragment is a fragment that expects to receive a result from another fragment, enabling communication between them without the need to use an Activity as an intermediary.
