Installing Android SDK on Windows XP – Hello World Application

You’ll find the full details for installing Android SDK at http://developer.android.com/sdk/installing.html. The purpose of this blog entry is to summarize what I had to do to install Android development environment (Android 2.3 SDK (Gingerbread)) on Windows XP. Before installing the Android SDK per se, you’ll need to install some set of tools used by the SDK. Here are the steps to setup your Windows XP computer for Android development: 1. Install Java Developer Kit (JDK) You need to go to http://www.oracle.com/technetwork/java/javase/downloads/index.html, select your OS (e.g. Linux, Windows, MAC…) and the file you want to download. I selected Java Platform (JDK), then downloaded Java SE Development Kit 6u23. I got the jdk-6u23-windows-i586.exe which I installed in the default directory, i.e. C:\Program Files\Java\jdk1.6.0_23). 2. Install Eclipse Classic Then you’ll need to install Eclipse, and open source IDE. Several versions are available at http://www.eclipse.org/downloads/, but since Google recommends Eclipse Classic, I just download […]
