Multi Screen Hell in Android

One small quibble: ONLY declare which screen sizes your app supports if it really does not support some screen sizes. You should usually consider that a bug. You need not declare non-support of an obscure size or configuration if not having size-specific resources is the only issue. Scaled images are not ideal, but it's better for the app to work and look a little fuzzy than to try to specify exactly where it does not look perfect.
