I just had a successful test !!!!!
My 145Mb game downloaded from google play, installed and launched
I guess that Intel will officially publish the plugin soon.
delaflaquita - for now, completing the process requires manual editing of intelxdk.config.additions.xml with some app data from your google play developer console, but this is not too complicated.
Interesting, would you like to tell us how to do this?
It would be a big news to community when we can make apk expansion.
