8. Follow Part III by iamareebjamal

If you were successful in accomplishing the above procedure. Be happy, but not too much because the key part is left, and that is - Adding those custom ICS Buttons in Settings by overriding the default GB tickview. Or else, you will get checkboxes instead of Switches. You don't wanna do that? Do you?

Enough talking let's roll

Part III (a)

1. Open AndroidManifest.xml located in decompiled Settings.apk

2. Find this:

Code:

<activity android:label="@string/settings_label_launcher" android:name="Settings"

3. Modify it like this:

Code:

<activity android:theme="@style/Switch" android:label="@string/settings_label_launcher" android:name="Settings"

It means you have to add android:theme="@style/Switch" between <activity and android:label="@string/settings_label_launcher"

4. Save the file.

5. Now, as you have edited the AndroidManifest.xml . Android system won't accept your app and refuse to load it as its signature should be changed.

So, sign the recompile the apk and sign it

6. But again, there's one little problem. Android doesn't load system apps with modified signatures for stability of OS, so your app will disappear from app drawer and if you try to open it from any other source, it will say "App isn't installed"

So?

So, sign ALL system apps and framework apps with same key

...OR...

Follow the workaround in (b) part

You may have accomplished the above thing but still something needs to be done to complete the procedure. Believe me, it's the last thing
Android System doesn't accept the apks that are signed by default. So we, here, will render that option obsolete by editing some files.

Let's start

Part III (b)

1. Pull services.jar from /system/framework/

2. Extract it's classes.dex and decompile it via my ROM Tolls

3. Go to com/android/server/PackageManagerService.smali

4. Open it and search for

Code:

.method checkSignaturesLP([Landroid/content/pm/Signature;[Landroid/content/pm/Signature;)I

5. Look below it, you should see something like this

Code:

    .prologue
    .line 1936

    if-nez p1, :cond_1

6. Add this below .line 1936

Code:

    const/4 v6, 0x0
    return v6

Finally, it should look like this:

Code:

.method checkSignaturesLP([Landroid/content/pm/Signature;[Landroid/content/pm/Signature;)I
    .locals 7
    .parameter "s1"
    .parameter "s2"

    .prologue
    .line 1936
    const/4 v6, 0x0

    return v6

    if-nez p1, :cond_1

7. Save the file and recompile classes.dex and then add it to services.jar

8. Now push services.jar and Settings.apk in their respective places and reboot the phone so that signature check changes are affected

9. Enjoy

Q: SGS3 Switches are small even if the image is large enough?

Solution :

1. Go to Res/layout/icon_check box_preference.xml
2. Find android:layout_width="68.0 px"
3. Change it to "85.0 px"
4. Find android:layout_height="20.0px"
5. Change it to "40.0 px"

Actually changing those pixels will not resize the switch pngs. It will make height's and width's available space larger, therefore switches can be strechted easily on their original size.

Q: On Part II, when editing .method onPause()V, should I delete only the title "method on pause()V" or from method on pause to .end method?

Solution :

You must replace whole method. Delete the on pause()V method then place the code I have written on the same place.
