How to force PreferenceActivity to deal with my SharedPreferences?

Question

I'm using SharedPreferences to store my data across all Activities within my application. I get access to it like this:

SharedPreferences mSharedPreferences = getSharedPreferences("MyPrefs", 0);

I've implemented PreferenceActivity so users can change values through it but it happens it reads/writes data not to "MyPrefs" but to:

PreferenceManager.getDefaultSharedPreferences(getApplicationContext());

Which is a bit unexpected for me. Is that possible to force PreferenceActivity to deal with my "MyPrefs" preferences? And what is the point to have several preferences within single application? Thank you.

It is possible and simple. This worked for me

public class SettingsActivity extends PreferenceActivity {
    @SuppressWarnings("deprecation")
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        getPreferenceManager().setSharedPreferencesName("MyPrefs");
        //getPreferenceManager().setSharedPreferencesMode(MODE_WORLD_WRITEABLE);
    addPreferencesFromResource(R.xml.preferences);
    }
}
