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 video, we'll cover the steps for setting up the SDK on Windows, from scratch. If you've already installed the SDK, but not the 4.1 API, I'll point out how to do that. So I have opened here the developer.android.com/SDK/index.html page where we can get the Android SDK. You can see by looking at the big blue button that the website has already detected our operating system.
If for any reason you need to download for another platform, you'll find a link if you scroll down just a little bit under the System Requirements and using an existing IDE listing. I want to point out that when you do this download you are not just getting the SDK, you're also getting Eclipse, along with the ADT, that's the Android Developer Tools plugin, the Android SDK Tools, the Android Platform-tools, the latest Android platform, and the latest Android system image for the emulator.
So let's go ahead and start the download. I'll agree to the licensing agreement and click Download the SDK ADT. As with many applications these days the initial download is quite small. In this case, you're actually downloading a ZIP file that will contain the various component parts. Once the download is complete we'll be able to uncompress up and continue. Alright, looks like we're done. I'm going to go ahead and show in folder. So there's my download. I'll double-click to uncompress and you'll see a very handy link that appears up top that says For instructions about setting up your Android SDK for first time, read Setting Up the ADT Bundle.
And if we go there you'll see a few steps outlined. So let's head back to Windows Explorer, and then I'm actually going to take this and put it on the desktop, so it will be pretty easy to find. You of course might want to put it in your root directory under another subfolder, perhaps one named Android or development. The move is complete, so let's go to desktop now. I'll open up that folder, and you can see there are two subfolders, eclipse and sdk. Let's go into sdk, and there you'll see five more subfolders. Drill down into tools, and once you see android, double-click that, and click Run.
That will start the command prompt, which in turn will launch the Android SDK manager. Now I want to point out right away that you may notice that instead of Android 4.1, you see Android 4.2 at the top here. Google has just released this, literally the day that we are recording this course. Unfortunately, there are no devices available with 4.2 installed on them, so we can't do any real testing and demonstration with them. So we're going to keep our focus on Android 4.1, which is beginning to enjoy a lot of devices using it now.
So I'll collapse Android 4.2 and open up Android 4.1.2. I'll select the main option, which will in turn choose all the other options there. And that's our latest platform that we're going to be developing for. We also want to select the earliest version that we want to develop for. And Google recommends that you choose android 2.2, which is Froyo, or frozen yogurt. Now I want to scroll down a little bit further to in the Extras folder and point out Google USB Driver.
You'll want to select this one also, as that will be needed for doing any testing of your device. Okay, with all those options checked, click the Install13 packages button. And the next dialog box that appears asks which packages of the selected do you want to actually install? Now we want to go ahead and choose Accept All here, because we're going to install them all. This can take upto 10 to 15 minutes to actually download and do the setup. However, if you only have a limited amount of time to devote to this process when you do it, you can install one at a time. Alright! Let's go ahead and click Install, and the process will begin.
Okay, the download is complete. And let's just verify that. I'll scroll down a little bit and now you can see the Google USB Driver is Installed. There is Android 2.2 Installed, and there's Android 4.1.2. Now you're ready to establish an emulator.
