addPreferencesFromResource deprecated - any other solution?

Question

I'm trying to create a preferences page to save user preferences.

Currently I am sat with this in preferences.xml:

<?xml version="1.0" encoding="utf-8"?>
<PreferenceScreen 
    xmlns:android="http://schemas.android.com/apk/res/android">

    <PreferenceCategory android:title="User Preferences">
        <CheckBoxPreference
            android:title="Save Credentials"
            android:defaultValue="true"
            android:summary="Save User Login Details"
            android:key="credentialsPref" />
        </PreferenceCategory>                

</PreferenceScreen>

And this in PreferencesActivity.class:

public class PreferencesActivity extends PreferenceActivity {

    @SuppressWarnings("deprecation")
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        addPreferencesFromResource(R.layout.preferences);
    }

}

That all works ok but it states that addPreferencesFromResource is deprecated, is there a better way of doing this - I have seen use of PreferenceFragment but it looks like an incredibly long winded way of going about this task, unless I'm mistaken?

Thanks
