PreferenceActivity not associated with "Settings"

I have my simple PreferenceActivity class and its onCreate passes my R.xml.preferences screen to ((PreferenceActivity)super).addPreferencesFromResource. Finally, in my AndroidManifest.xml my activity as follows:

<activity android:name="com.criticalrf.jwalkietalkie.PreferenceServerActivity" >
    <intent-filter>
       <action android:name="android.intent.action.MANAGE_NETWORK" />
       <category android:name="android.intent.category.DEFAULT" />
    </intent-filter>
</activity>

On the device, the menu button will trigger a menu with only the word "Settings." Clicking on Settings makes the Settings button go away but does not show anything. Do I need to add something in my MainActivity? I followed this guide, I'm not sure what I missed.

If you want to open this preference activity from your main activity you should call somewhere in your MainActivity: 

startActivity(new Intent(this, PreferenceServerActivity.class));

and preference activity will show.

Typical implementation would be doing it with options menu. Like:

    private static final int SettingsId = 1;

    @Override
    public boolean onCreateOptionsMenu(Menu menu)
    {
        menu.add(0, SettingsId, 0, "Settings");

        return true;
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item)
    {
        switch (item.getItemId())
        {
            case SettingsId:
                startActivity(new Intent(this, PreferenceServerActivity.class));
                return true;
            default:
                return false;
        }
    }

Intent filter in your manifest from tutorial just says, that this activity can be opened from system settings when user browse data usage of your app.
