2.Notepad ++ or Editor Alternatives
3.Apktool to Decompile apk
4.A Little Common sense


1. Decompile Settings.apk

2.Open to res/xml/settings_headers.xml

3.Lets take an example i want to Add "Maddy" as a activity header

add this line

 <header android:icon="@drawable/ic_settings_maddy" android:id="@id/maddy_settings" android:title="@string/maddy_settings" android:fragment="" />
The layout in settings_headers.xml is categorized. If you want submenu "Maddy" to appear after 'Apps' as shown,add the line after the line that says <header android:icon="@drawable/ic_settings_applications"..... as shown

 <header android:icon="@drawable/ic_settings_applications" android:id="@id/application_settings" android:title="@string/applications_settings" android:fragment="" />
 <header android:icon="@drawable/ic_settings_maddy" android:id="@id/maddy_settings" android:title="@string/maddy_settings" android:fragment="" />

3.1-@drawable/ic_settings_maddy=This refers to the png in res/drawable-*dpi/ folder

Add a new png named ic_settings_maddy.png in res/drawable-*dpi/
It will be the Image that will show up in settings menu (The Wifi like icon in my case)

* = hdpi / mdpi /xhdpi /xxhdpi /xxxhdpi (Depends on your device)

3.2-@id/maddy_settings=This refers to id value in /res/values/ids.xml

Open res/values/ids.xml and add this code

<item type="id" name="maddy_settings">false</item>

3.3 - @string/maddy_settings = Refers to a string in res/values/strings.xml

Open strings.xml and add this code

<string name="maddy_settings">Your String here</string>
Add the string you wish to see in settings Submenu in place of 'Your String Here' = Refers to the smali file in smali/com/android/settings/

4. Open res/values/public.xml
and find the last line that says
<public type="xml" ...

<public type="xml" name="somethig_something" id="0x7f050053" />
Note the Hex code in Blue.It can be different for you
and now add this line just after the last line of type="xml"

<public type="xml" name="maddy_settings" id="0x7f050054" />
Also Note that the previous address in my case was 0x7f050053
so the new address will be "Previous address + 1(Hex addition)" i.e 0x7f050054

Replace 0x7f050054 with your calculated Address.

If your Address is 0x7f050039
Next Addres = 0x7f05003a

if your address is 0x7f05003f
next address = 0x7f050040
and so on..

5.Go to res/xml/
and add a new file named maddy_settings.xml

This xml would contain the Apps/Actions you wish to see inside the Submenu "Maddy"

Just like you see

Screen timeout
etc etc

options when you click Display in Settings Menu
an example of what maddy_settings.xml may contain

PHP Code:
<?xml version="1.0" encoding="utf-8"?>
<PreferenceScreen android:title="@string/maddy_settings"
    <com.sonymobile.settings.preference.PreferenceCategory android:title="@string/uipref_title">
        <PreferenceScreen android:icon="@drawable/cust_bar_wallpapers" android:title="@string/wallpaper_settings_title" android:key="wallpaper" android:fragment="" />
        <com.sonymobile.settings.preference.IntentPreference android:icon="@drawable/ic_lighteffects" android:title="@string/light_effects_settings_title" android:key="light_effects" settings:dependOnIsValidIntent="true" settings:after="theme">
            <intent android:targetPackage="com.sonymobile.settings.illumination" android:action="android.intent.action.MAIN" android:targetClass="com.sonymobile.settings.illumination.IlluminationSetting" />
        <com.sonymobile.settings.preference.IntentPreference android:icon="@drawable/homescreen_application_launcher" android:key="lockscreen" settings:dependOnIsValidIntent="true" settings:hasMetaData="true">
            <intent android:action="com.sonyericsson.settings.intent.action.LOCKSCREEN" />
    <com.sonymobile.settings.preference.PreferenceCategory android:title="@string/systemuipref_title">
        <com.sonymobile.settings.preference.IntentPreference android:icon="@drawable/ic_systemui1" android:key="quicksettings" settings:dependOnIsValidIntent="true" settings:hasMetaData="true">
            <intent android:action="com.sonymobile.intent.action.TOOLBAR_SETTINGS" />
        <com.sonymobile.settings.preference.IntentPreference android:icon="@drawable/ic_systemui2" android:key="power_toggles" settings:dependOnIsValidIntent="true" settings:hasMetaData="true">
            <intent android:action="com.serajr.powertoggles.preferences.intent.PREFERENCES" />

To Add these Apps/shortcuts to the submenu you just created,refer this guide [Tutorial] How to add any App/Option in Settings.apk by saqib nazm
Just use the new maddy_settings.xml to link your new apps/actions.

6.Open smali/com/android/settings/ and add a new file named Maddy.smali

paste this code in it

.class public Lcom/android/settings/Maddy;
.super Lcom/android/settings/SettingsPreferenceFragment;
.source ""

# direct methods
.method public constructor <init>()V
    .locals 0

    .line 17
    invoke-direct {p0}, Lcom/android/settings/SettingsPreferenceFragment;-><init>()V

.end method

# virtual methods
.method public onCreate(Landroid/os/Bundle;)V
    .locals 1
    .parameter "savedInstanceState"

    .line 21
    invoke-super {p0, p1}, Lcom/android/settings/SettingsPreferenceFragment;->onCreate(Landroid/os/Bundle;)V

    .line 23
    const v0, 0x7f050054

    invoke-virtual {p0, v0}, Lcom/android/settings/Maddy;->addPreferencesFromResource(I)V

    .line 24
.end method
Find and replace "Maddy" with your smali name.
Smali names should always start with Capital Letters.

Also note the Hex code you added in Step 5.
replace 0x7f050054 with your Hex value.

7.Recompile your Apk and Done!

Should work with any versions of Xperia.
Also may work on other Devices,Please try and report.
