This is part 5 of a 5-part series on introductory Android development. If you’re just arriving, you should head on over to Part 1. Warning: While the general ideas and Android-specific code contained here still apply, the Twitter-specific portions are now outdated thanks to the so-called “OAuthocalypse,” Twitter’s phasing out of HTTP basic auth.
In Part 4, we dug into accessing our Views from our Activity’s code, and registered an OnClickListener to handle the user’s interactions with our button. In the final part (a big one!) we’ll cover using J2SE libraries, debugging, and Android permissions.
So far we’ve gotten a lot done without too much “boilerplate” coding, and that’s great. But what we don’t have (yet) is an application that leaves its mark on the world. After all, what’s a Twitter application if people can’t benefit from your 140 characters of deep, meaningful insight into the state of the world (or what you ate for breakfast)?
