Specifying what assets go into Expansion file in Android
According to https://coronalabs.com/blog/2013/04/17/expansion-file-support-for-android/, it seems to be a Corona feature which takes all assets except lua scripts and put them in a downloadable package.
This is a problem for us since some assets need to be in the main apk file. We only have two options usesExpansionFile = true (or false), but no option to specify how to prevent certain assets to be included in the expansion file ( and be part of the main apk). This is causing a few problems and it would be great to have this feature.
