[Q] How to change Mms.apk background - Galaxy S II Q&A, Help & Troubleshooting

Hello to all of you!
I have to ask you some advice, because I really don't know how to solve my problem, even if I have looked a lot for a solution.
I would like to change background color of my Mms.apk. I attached the one Mms.apk I am using.
This is what I did several time:
1. Decompiling Mms.apk
2. Editing listitem_background.xml in /res/drawable/, replacing transparent with bright_foreground_light, a color I have found in my framework-res.apk.
3. Recompiling my Mms
4. Putting it in /system/app with 644 permissions
Every time I follow these steps, my new Mms.apk results to be not installed and I don't know what to do!
Can you help me?

Just use secondary messaging app, like GO SMS Pro or Handcent. You can tweak those settings in these apps.

Thanks for your advice, but I really would like to learn something about modding apk.

I think you need to sign the apk to make it install!

I have followed advices in that post but my apk still doesn't work. Maybe I am wrong with something about signing apk, I have generated a signature called like the one in that post and use it, but, if I decompile Mms.apk and rebuild it, without editing anything, my apk still doesn't work.

---

I have solved the issue of signature by replacing META-INF and AndroidManifest.xml in the modified apk with the ones in the original one.

delca85,
I'd like to change my background color to black. Can you explain to me what you did to change yours?
I looked at the res/drawable/listitem_background.xml and I see three colors.
Which one did you modify?

I'm sorry but I haven't been able to find the way to edit Mms background. Maybe you can find something in Google, I will keep on trying, if I'll find something, I am going to write it here.

When i change message (and phone, home and contact) icon to look like s2 on my galaxy ace i do this.
1. Copy mms.apk in /system/app folder to pc
2. Rename it to mms.zip and unzip
3. Edit icon and put edited .png file back to mms.zip (dont create new zip)
4. Rename mms.zip back to mms.apk and put it to /system folder and now change file permissions
5. Move mms.apk to /system/app folder and overwrite
6. Reboot
sorry my english

Sepp82, I don't have any problem to change png, but, in this situation, I have to edit some xml and I don't know which and how.

ALWAYS BACK UP ORIGINAL APK FILE!!!
I use ninja morph from the market, edit what i want and then exit out, open root explorer,go into androidthemes/workspace,delete the META-INF folder,exit root explorer. Open ninja morph, goto Finish Project, and select project you're working on. Boom done. Open Signapk from market, hit next choose your file,platfom,next,let it do its thing hit finish at the end, root explorer install or copy paste to system.
