[Android Q&A, Help & Troubleshooting] MaxFTW:
I had been looking before for the same thread I created, but I hadn't found so I created this one. I want to mod some apps for my Jelly Sandwich ROM. Decompiling goes well, but recompiling - error!

This what I exactly do:

apktool if framework-res.apk (success)

apktool d SystemUI.apk (success)

apktool b SystemUI.apk (error)

This is what I get after recompiling command:

I: Checking whether sources has changed...
I: Smaling...

Even without changing anything, apktool doesn't recompile my apk.

I have tried to recompile on two PCs - both of them have latest Java software installed.

-----------------EDIT------------------------

I got something like that once also:

I: Checking whether sources has changed...
I: Smaling...
I: Checking whether resources has changed...
