I just downloaded r90 today and exported a project. Also installed the latest version of appmobi's xdk on chrome, and their directcanvas sdk.
Tested on the Mac (also on pc), using appmobi browser simulator. Their sample do work, but Construct's exported do not work.
I think the problem is that the exported index.html references a _appmobi/appmobi.js which do not exist on appmobi's sdk, even the other ones not specific to directcanvas. Only xhr.js exists on the sdk.
Instead, their sample has a appmobi/appmobi_shim.js, so I copied it and modified the exported project to use it, but it still does not work, only does something partially (sound starts and the screen now is black, but nothing else).
Where can I get the missing _appmobi/appmobi.js ? or do I have to use the appmobi build? I think it is probably going to fail too.
