density-specific resources on Android in Alloy

So, i'm having problems with Android resolutions in Alloy, i just read the documentation and is a total lie, this is the link:

http://docs.appcelerator.com/titanium/latest/#!/guide/Using_density-specific_resources_on_Android

The High, Medium and low folder options, doesn't work at all.

The "res-land-hdpi" folder estructure neither.

So, how the actual hell you do that?, i have no idea, for real.

Thanks for your help.

I'm testing the App in:

Samsung Galaxy Note 3

Motorola XT910
