If you are just blindly scaling images, it is worth thinking about whether it is worth including them as separate densities. If you don't provide the appropriate density, Android will at the point of loading the drawable generally scale it to match the density it needs. So if you do things right, you will take some overhead at load time for the scaling but that is it.
Of course there is an unfortunate trade-off -- if you do this you will want to include the highest-density images, but devices with lower-density screens tend to be the lower-end ones and you are then putting more of a burden on them when loading the asset. I don't think it should be too much of a problem, though I haven't tried it extensively. The other negative is that the device's run-time scaling is not going to be as good as the stuff you will get with high quality time-insensitive graphics manipulation on a desktop machine. And in either case you need to be careful with 9-patches. Well if you are doing the scaling yourself, you of course need to be careful that the marks around the edge stay at one pixel in size. And if you are letting the device do the scaling, it is not hard to make 9-patches that when scaled have bad artifacts. For example, you would want to make sure that every section as at least 2 pixels in size so that they don't disappear when scaled, and more than that if you are going to let things scale by more than 2x down.
