1. JDK Installation and configuration

First go here http://www.oracle.com/technetwork/java/javase/downloads/index.html download, and then the next step to complete the installation.

After the download is complete, you will see Eclipse, SDK, and then launch Eclipse.

Next, download and install some SDK packages as needed, and click on the SDK Manager icon in the toolbar

When the Android SDK Manager window pops up, the SDK packages that can be installed and updated (depending on the time of the network) are refreshed and selected for installation.

OK, come here first, next time we'll have a HelloWorld and run on the simulator.
