The following is the first few sections of a chapter from The Busy Coder's Guide to Android Development, plus headings for the remaining major sections, to give you an idea about the content of the chapter.
Oh, what a tangled web we weave
When first we practice to work with SMS on Android, Eve
(with apologies to Sir Walter Scott)
Android devices have had SMS capability since Android 1.0. However, from a programming standpoint, for years, SMS and Android were intensely frustrating. When the Android SDK was developed, some aspects of working with SMS were put into the SDK, while others were held back. This, of course, did not stop many an intrepid developer from working with the undocumented, unsupported SMS APIs, with varying degrees of success.
After much wailing and gnashing of teeth by developers, Google finally formalized a more complete SMS API in Android 4.4. However, this too has its issues, where some apps that worked fine with the undocumented API will now fail outright, in irreparable fashion, on Android 4.4+.
This chapter starts with the one thing you can do reasonably reliably
across Android device versions –
send an SMS, either directly or by invoking the user’s choice
of SMS client. The chapter then examines how to monitor or receive
SMS messages (both pre-4.4 and 4.4+) and the SMS-related
(both pre-4.4 and 4.4+).
Understanding this chapter requires that you have read the core chapters,
particularly the chapters on broadcast
