Help to port MOD Touchwiz from AT&T to i9300 intl

[cybdani]

Hi all!
I'm trying to port a touchwiz mod from AT&T to i9300 intl. The goal is to center all apps icon in touchwiz. Hotseat.smali are very different from one version to other.
The problem is (I think) ".field private static final sAllAppsButtonRank:I" doesn't exists in hotseat international version.

Originally the how-to was made by magn2o in this post http://forum.xda-developers.com/showpost.php?p=30909479&postcount=70

And this is the code to modify:

I just want to make sure I'm interpreting your message correctly: The purpose of that mod is to cause the app drawer icon on the home screen to be in the center of the dock instead of the right side of the dock?

How familiar with smali are you?

You might have to get the proper apk from an AT&T firmware, decompile it, and study the smali, and then do the same with an international apk. Use the AT&T one just to provide "hints" on the general things to look for in the international one.

Take care

Yes, that is.

I started learning a month ago (totally noob). I've published a rom (based on stock) in my blog site with some modifications. Learned some mod tutorials and how-to from xda.

I've decompiled SecLauncher2.apk modified (from AT&T MOD thread) compared some files and code and no luck with that.
For example, mod is based in this: private static final sAllAppsButtonRank:I = 0x2 (change 0x4 to 0x2). But intl version does not have sAllAppsButtonRank in code. Tried to add this code in hotseat.smali and modified LauncherModel$LoaderTask and LauncherProvider$DatabaseHelper. Of course (because I'm noob), it doesn't works. I've found some web sites to start learning smali code but not a "complete" guide.

Thanks a lot for your help!

You cant just drop in a variable and expect code to suddenly use it just because it exists. Chances are that the international version does nearly the same thing, but without the constant variable. You'll have to figure out how the code works; it's not enough to just copy things. That's the difference between developing and just taking stuff from other people.

When I get to my PC later, I'll give you a link that explains what the smali commands do, and you can reverse engineer from that.

The expectation is that you'd rather learn HOW to do this type of thing... Not just have someone do it for you (or give you the exact steps for it.)

Thank you very much.
Time to learn now :good:
