You can hardly say iOS supports only one resolution now can you? Thing is - Apple dictates certain limitations AND provides the tools and api's to make it more convenient to support those different resolutions and dpi. On Android you not only have to worry about resolution and dpi, which you could do on simulators, but you also have to take into account which display technology is used. Text on pentile displays can look horrible on the real device, while looking perfect on the "same resolution" in a simulator (real world story here). That and designing a good UI which's size is dictated by an unpredictable aspect ratio, size (resolution + DPI) is bloody hard. Just look at the total lack of tablet apps for Android. So yes, if a developer pours the same effort into an Android app as it does in an iOS app, you get poor results. Welcome to the real world.
