The Eclipse Integrated Development Environment (IDE) is essential for creating your Android apps. Prior to jumping in and using it, there are some accompanying programs that are necessary. With that being said, let's start our journey on the road to Android development by downloading and installing some prerequisites first.
Download and install the Java SE Development Kit
The Java SE Development Kit (JDK) allows you to develop Java programs. You will need to have it installed for the Android SDK to work properly. Having just the Java Runtime Environment, which lets you run Java applications and applets, is not enough. So, if you do not already have the JDK installed, do so now. Visit the following link to install the program:
http://www.oracle.com/technetwork/java/javase/downloads/index.html
Click on Download JDK. You will be taken to a page where you must select the platform for your download. You can choose between Linux, Solaris, and Windows. We will use Windows for this installation. Check the box to agree to the license agreement and click Continue.
On the next page, click on the .exe file to begin the download. Depending on your browser, you will be asked to either save or run the file. Since we are using Firefox, we will save the file. After the file has downloaded, double-click it to begin the installer.
The JDK installation wizard will appear. Click Next
