Yes, you are right that my book does not cover the API basics of J2ME/MIDP. However, for beginners, it provides a useful survey of the mobile
Java technology landscape (e.g., mobile database, security, web services beyond standard MIDP etc.) It may or may not be what you need. Just thought that I should mention that.
If you are looking for an API tutorial book, this book is very good
