My first book C Programing Techniques for the Macintosh was pretty niche. For example, it required third-party compilers and other tools to do self-hosted development on a 512k Mac. But you had to buy it because Apple's documentation had no tutorial content at all, just an API reference.

If you look at Google's documentation of Android now, you don't need to supplement it.
