publish app with expansion file

I have referred many related links but i was not successful yet .
I have an app with 615 mb , so i have optimized such that my main .apk has 24 mb and rest in the extension file as .zip . Now i could not find where to upload my extension .zip file in the Play Store .
I have referred :
http://docs.xamarin.com/guides/android/deployment,_testing,_and_metrics/publishing_an_application/part_2_-_publishing_an_application_on_google_play
http://developer.android.com/google/play/expansion-files.html
can you please suggest me where to upload this extension file . It would be helpful if any tutorial or step by step process is explained .
Thanks in advance .
Sometimes the extension file upload simple don't appear. I have solved it by switching to advanced mode, unpublish the current version, and when I upload the new version it ask for extension file.

You need to build them yourself. See /jni/build.bat and /jni/build.sh.
for individual andengine examples:
http://code.google.com/p/andengineexamples/source/browse/src/#src%2Forg%2Fanddev%2Fandengine%2Fexamples%253Fstate%253Dclosed
the jar is located here. right-click and choose "save as":

What is resources.ap_ and why does it have a penchant for not existing?

Every once in a while a borked Eclipse build gets nailed down to the absence of this file, with the simple fix of cleaning the build, or occasionally doing a deeper clean on the project's metadata. I can live with this state of affairs, but the curious side of me has to ask why.
A search for it on developer.android.com turns up nothing :(, and a search on Google turns up various threads by folks wondering why their build is broken.
This guy is the closest thing I've found to an explanation of the thing itself. Hopefully some nice, patient guru can shed some light on the fundamentals here without this noob digging too far into the source :)
The resource.ap_ is all the resources for you file zipped up. Everything from the res, assets folders and the Manifest file.
The apk file added in the class.dex (all your compiled code) and any linked .so (native code).
Both of these files are in .zip format. They can easily be view by changing the extension to .zip and opening them.
The .ap_ file is probably your apk before it is signed with your certificate (by default, a debug certificate generated by ADT in your home directory.)
here is a picture which may give you the answer.
