So I should set it to true even when my app doesn't include resources to accommodate any screen density (suppose I'm lazy so I don't create any size- or density specific resources)?
I'm wondering this because taken from: http://developer.android.com/guide/topics/manifest/supports-screens-element.html it says that if you set "anyDensity" to true it means "the application includes resources to accommodate any screen density". But I'm not including any of these explicitly, so what happens then scaling wise when anyDensity="true"?
