That works if you are only making res edits to normal png's. However, I am also trying to edit the .9.png's and the xml's. In order to not lose the integrity of those files, the apk must be decompiled and recompiled. Mostly this is done using the apktool v1.4.3. But, with ICS it is giving me some issues during the recompiling and producing errors. Not sure why. Before, with GB roms, this was never an issue, just started with the ICS ports. I read that there are changes to the smali with ICS roms, and read more as to the fix, but none of the fixes are working for me and I keep getting errors, as with most of the people I have researched trying to use the fixes. Just looking to find out how Phoenix is doing it.

As far as just editing the png's, NinjaMorph works great if I don't mess with the xml files or the .9.png's.
Depends on the apk you're trying to decompile/reompile.
I found a guide somewhere on XDA that explained using AutoAPKTool 2.0.0 (HAS TO BE THAT VERSION) and you can decompile Framework-res and twframework-res.apks ok, but to recompile I have to edit a line in the plurals.xmls (there are like 5 or 6 inside Framework-res.apk) basically one of the lasts lines look like this (in all of them)...
<plurals name="matches_found">
<item quantity="other">%1$1$d von %2$2$d</item>
<item quantity="one">1 Übereinstimmung</item>
</plurals>
</resources>
On THIS line....
<item quantity="other">%1$1$d von %2$2$d</item>
YOu have to add another % at the end to look like this...
<item quantity="other">%1$1$d von %%2$2$d</item>
Save and recompile once you've changed all of them (again, this is for framework-res.apk only)
Sammy messed up some and this is the fix I found, another member edited my theme with some things I missed and fixed this problem so once I up those they should recompile normally, I think.
FOR the SystemUI.apk you have to open it in something like winrar and take out the classes.dex file, save it somewhere, then delete it from inside the APK, then it will decompile/recompile fine, again using this AutoAPKtool 2.0.0 (you have to google it, its a pain to find, sorry, not at home atm to upload for you)
Once you're done and the SystemUI.apk is resigned, you can use WinRAR to put the classes.dex back.
Sorry this is a mess of an explanation, I did a LOT of googling when I started this theme because of these very problems. I am at work and don't have much time to really get into explaining everything thoroughly but hope this helps.
