Java: The Good Parts Version
Well, OK, actually, that last one is another Mark Murphy. But, I digress.
If you are in need of a crash course in Java to get involved in Android development, here are the concepts I would focus upon, with links to relevant sections of the Java Wikibook:
- Language fundamentals (flow control, etc.)
- Classes and objects
- Methods and data members
- Public, private, and protected
- Static and instance scope
- Threads and concurrency control
- File I/O
