[Q] Porting L Calculator to 4.1.2

I am trying to port the Android L Calculator to 4.1.2

I have successfully decompiled, edited XML, and recompiled (without using my framework-res.apk in CMD prompt)View attachment Calculator_signed_zipaligned.apk

I have tried decompiling, editing XML, and recompiling using the framework-res.apk from my phone but i get an error:

I am using these two tutorials to try to port this app: http://xdaforums.com/showthread.php?t=2476050, http://xdaforums.com/show....php?t=2195680

This is my first time trying to port anything, so forgive me if I'm way off track.

Here is my successful (?) compilation of the edited apk. [SEE ATTACHED FILE]
If a Dev could take a look (or someone more knowledgeable than myself) and perhaps give me a tip or two I'd appreciate it.
Trying to show my fellow JB users some love in getting us some newer apps. If I can backport this successfully I will gladly try backporting many other apps from Lollipop and other OS.

Thanks for any help I may receive!

I've tried installing this signed apk but I get a parsing error...

No one? Wow.... Please someone help me out here. I'm using the cyanogenmod calculator but I would like a smaller foot print on my device. I'm trying to do this myself with no prior experience so that maybe I can learn something. Is this a developer forum or what?
