Installing and configuring the Eclipse plugin - Smartphone Development
Have you ever had the urge to develop your own apps for the Android platform? If so, this tutorial will help you begin setting up the foundation to do so. You will need various components before you can begin developing your applications, and we will show you how to install each component step by step, beginning with the Java SE Development Kit and the Eclipse IDE.
Locate the executable file for Eclipse. It will be located in the Eclipse folder in your Android directory:
C:\Android\eclipse\eclipse.exe
Double-click or run the file to load the program. Before the program fully loads, you will be asked to select a workspace. Browse to the workspace folder you previously created:
C:\Android\workspace
Click OK. The Eclipse IDE should load and you should see a welcome screen. At the top of the screen, click Help and select Install New Software. In the Work with field, paste one of the following addresses:
Click Add. In the middle of the screen, you should see Developer Tools appear. Expand it to see four sub-categories. Click Select All. Click Next.
The Install Details page will show you what you are about to install. Click Next.
Accept the license and click Finish. The software installation will begin. Give it some time to finish. After it is finished, you will be asked to restart Eclipse for the changes to take effect. Click Restart Now.
Eclipse will restart and ask you to select a workspace. Select the C:\Android\workspace and click OK. In the Eclipse interface, click on Window then Preferences. Click on the Android section on the left. Click Browse. Select your Android SDK folder. It is one of the three folders in the Android directory you created earlier. Click OK.
You should now be able to begin developing Android projects. To develop a new project in the Eclipse interface, simply go to File > New > Project. Select Android Project and you can start immediately.
