Decompiling 2.2 files

---

Hello,

I am trying to edit settings.apk and some of the library files such as libskia.so for the new firmware in order to localize them. apktool isn't succeeding decoding the settings.apk file for 2.2 even though it was fine with 2.1 firmware. Does anyone know how I can decode the 2.2 files by using windows or cygwin? Thanks...

Do you have add Froyo's framework-res to the apktool?

apktools if system/framework/framework-res.apk

I did that but I still get errors such as:

W: Could not decode attr value, using undecoded value instead: ns=android, name=
textColorHint, value=0x02050001
Can't find framework resources for package of id: 2. You must install proper fra
mework files, see project website for more info.

Here is another question, how can I find samsung galaxy s 2.2 resources? I believe that's what I am missing to get it working. I think it might be a file like this com.samsung.resources.apk or similar.

EDIT: I managed to decode settings.apk successfully by adding twframework-res.apk to apktool. Now I just need to figure out how to edit libskia.so for 2.2.

Have you edited it in firmware 2.1?

Nearly impossible: it's native code, you know. Even worst: ARMs aren't so popular as PC, so there aren't too many ARM disassemblers/decompilers for them.

But I think it's just a image processing library, so... what to localize in it?

it has been done using linux. however, I am trying to use cygwin to do it but I can't seem to have the dpkg command installed in cygwin.

I am trying to add another language to 2.2. We managed to add it to 2.1 but 2.2 seems to use different encryption method which we haven't managed to successfully decode.

Encryption? It's a library file, like .dll on Windows. It's not encrypted, it's just compiled, like any .dll, .exe, etc. on your PC.

Did you succeed in "decrypting" libskia.so from 2.1?

Encryption might not be the correct word. When you "compile" these files, sometimes there are headers associated with them, without them, it would be very difficult to "decompile" them in order to edit it.

Ok, but Skia is an open source project, it's a part of AOSP :) Of course Samsung may modified something in it, but I doubt it.

EDIT:
And still it's illogical to me, that there is something to localize in image processing library.
