[Android Software Development] RL77LUC:
I've do "apktool if framework-res.apk". So, yes, I think.

EDIT: I've try with aapt.exe of platform-tools from SDK. I get this error :

W: Could not find sources
I: Checking whether resources has changed...

Thx for your help.

EDIT2: Finally, I've done.

Tip: Decompile with apktool 1.4.2 and recompile with 1.4.3 ... Works fine. But how can I set DPI of on-screen buttons to 48dpi, with no keyboard problem ? Like 3rd update of this : http://xdaforums.com/showpost.php?p=20967433&postcount=171

EDIT3: With global DPI to 230, no keyboard bug anymore, but quality isn't very good (icons/status bar). And an other question : How Can I ake a flashable zip ? I've followed your links, but I get a Status 0 : Installation Aborted ...
