This course introduces the new features offered to developers and consumers in Android 4.1 Jelly Bean. Author Joseph Lowery first explains how you can expect the update to roll out to devices, and then shows how to install the Android SDK on Windows and Mac, select a device emulator, create a sample app, and prep it for publication on Google Play. Along the way, the course explores the smoother interface (codenamed Project Butter), notifications, advanced text manipulation, and security improvements that will be of interest to Android developers, and describes how those features translate for consumers on the device side.
Installing the Android SDK for Jelly Bean is an essential task for anyone developing an App. In this lesson we'll cover the steps for setting up the SDK on the Mac. And if you've already installed the SDK, but not the 4.1 API, I'll point out how to do that. Let's start by going to developer.android.com/SDK/index.html. The website automatically detects your platform. And the Big Blue button there is ready to be clicked.
However, if you scroll down a little bit, you'll see a download for other platforms link, and you can use that to get the SDK for any other platforms. Now you'll notice that this button not only downloads the SDK, but it also downloads the ADT bundle for Mac. ADT stands for Android Developer Tools, and in this bundle you get everything that you need, Eclipse plus the ADT plugin, the Android SDK Tools, and more. So let's go ahead and get started. I'll click Download the SDK, and then agree to the license agreement, and click Download the Bundle.
As with many applications these days the initial download is quite small. In this case you're actually downloading a ZIP file that contains the numerous tools we were talking about, the primary piece of which is the Android SDK Manager. Alright, now that it's downloaded, I'm going to Show in Finder, and there it is in my Downloads folder. I'll double-click it to uncompress. Now within the Android SDK MacOS X folder, you'll find a series of other folders.
Let's drill down into tools and then select android. Now you could open this up with just Terminal, but I'm going to just double-click it and open up Terminal automatically. And once you're in the Android SDK Manager we'll need to still get the essential tools that we'll need. This, by the way, is where you'd come if you'd already had the Android SDK Manager installed previously and just wanted to get the Jelly Bean API. So since we're just starting, we're going to go ahead and select the Android SDK Platform Tools that you see here.
Now Android 4.1.2, which is the latest version as of this recording, as you can see, is already selected for downloading and you can see also on the right that it's not installed yet. That's correct, we're going to want to get those, and you also want to get the earliest version of the API at your App will support. Google recommends that you choose Android 2.2, or Froyo, which is short for frozen yogurt. I want to stress that while Google recommends this as the earliest version for you to develop for, your needs may be different.
Now we're also going to want to get an item or so under the Extras category. So let me expand Extras and then scroll down. I'm going to go ahead and pick up the Android Support Library. And you'll notice that there is a Google USB Driver here. We don't need to get that for the Mac, but if you're developing for Windows you would need that. Once you have made all of your selections, click the Install button. The next screen that's shown shows which packages that you actually want to install.
The manager will pull out your selections and allow you to install them one at a time or all at once. We're going to install them all, so I'll click Accept All. Now although it will actually take 10 to 15 minutes for this to download and set up, in this lesson it will appear to take no time at all, thanks to the magic of editing. If you only have a limited amount of time to devote to this process when you do it, you should install one at a time. Alright, I'll click Install, and the downloading has begun.
Well it looks like all my installations went through. Let me just verify by scrolling up, and there are all the 4.1.2 elements installed, excellent! Your SDK is set up on your Mac, and now you're ready to create an emulator.
