PreferenceScreen see domentation here

PreferenceScreen class can appear in two places:

• When a PreferenceActivity points to this, it is used as the root and is not shown (only the contained preferences are shown).
• When it appears inside another preference hierarchy, it is shown and serves as the gateway to another screen of preferences (either by showing another screen of preferences as a Dialog or via a startActivity(android.content.Intent) from the getIntent()). The children of this PreferenceScreen are NOT shown in the screen that this PreferenceScreen is shown in. Instead, a separate screen will be shown when this preference is clicked.

PreferenceManager see documentation here:

Difference :

getPreferenceManager () returns the current preference manager associated with the fragment.

getPreferenceScreen () returns the root PreferenceScreen i.e. root preference screen used in the fragment from preference xml file(preferences.xml).
