I would say most of it IS appropriate. A lot of the advice is good for Java development in general, regardless of platform. Enums are one area that is hotly debated in the Android community, but there is no consensus on it.
Generally, I would say follow the advice in Effective Java, but be aware of some potential performance issues and how you can avoid/fix them if need be.
Edit: I noticed there is a chapter on serialization. This can be ignored by Android developers in favor of Parcelable.
