Add music controls to lockscreen (GOT 2.2.1)

I need to contact with someone with enough experience in smali editing to port music controls to lockscreen. I got the smali with the controls (from a Droid). I only need this to finish a theme. Anybody?

PD: I don't speak German, sorry.

Post the files and I will look into it.

Is the source code for this available?

In cyanogen is related to CMParts.apk, in my source mod its only in android.policy.jar->lockscreen.smali

Ill post em on a zip

Attached the zip with the smalis.

with MOD:

Lockscreen.smali
Lockscreen$1.smali
Lockscreen$2.smali
Lockscreen$3.smali
Lockscreen$4.smali
Lockscreen$5.smali
Lockscreen$6.smali
Lockscreen$7.smali

my smalis:

Lockscreen.smali
Lockscreen$1.smali
Lockscreen$2.smali
Lockscreen$3.smali
Lockscreen$4.smali

Note: the MODED lockscreen has a lot of extra mods. I just want the music controls, and in some part of the music controls mod the code calls for some lockscreen$x(some numbers), thats why i added em.

You may want to compile it from source instead of hacking around with smali bytecode. It's in the cyanogen sources and it should be possible to merge with the aosp sources.
