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While the general ideas and Android-specific code contained here still apply, the Twitter-specific portions are now outdated thanks to the so-called “OAuthocalypse,” Twitter’s phasing out of HTTP basic auth.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)?

In Part 3, we defined our layout and prettied up our app’s main screen. Now let’s get to the business of real coding – the stuff that makes the app tick behind the scenes.

In the first part of the tutorial, we got Eclipse, the Android SDK, and the ADT set up. In this part, we’ll get into our environment, create our first project and poke around in it, and test out the Android emulator.

Fire It Up

Go ahead and fire up Eclipse, and if it asks, choose a workspace (the default’s probably fine for now). Click on the “new android project” button or go to File -> New -> Android Project.

Click the New Android Project button.

Thinking about testing the waters with Android development? Jump right in. We’ll build a neat little application that interacts with a web service.

Yup.

Which one? Twitter, of course.

This is a web form of a talk I gave with Henry Cipolla, CTO of Localytics, at BarCamp Boston 4 and in a longer form at FITC Mobile 2009, updated to cover the 1.6 (“Donut”) release of the Android SDK. The slideshow portion of that talk covers the basic concepts of the platform and slides are available online. I recommend checking it out.
