Install Eclipse, the ADT Plugin and the most recent Android SDK

[cesine]

This is usually a gig of downloading, so be sure you plan to do this when you have reliable internet (ie at home before going to a workshop or hackathon)

0 If you dont already have Eclipse, download Eclipse for Java Developers

• http://www.eclipse.org/downloads/packages/eclipse-ide-java-developers/junosr1

1 Install the Android Development Tools Plugin

1. Start Eclipse, then select Help > Install New Software.
2. Click Add, in the top-right corner.
3. In the Add Repository dialog that appears, enter "ADT Plugin" for the Name and the following URL for the Location:
   https://dl-ssl.google.com/android/eclipse/
4. Click OK.
   If you have trouble acquiring the plugin, try using "http" in the Location URL, instead of "https" (https is preferred for security reasons).
5. In the Available Software dialog, select the checkbox next to Developer Tools and click Next.
6. In the next window, you'll see a list of the tools to be downloaded. Click Next.
7. Read and accept the license agreements, then click Finish.
   If you get a security warning saying that the authenticity or validity of the software can't be established, click OK.
8. When the installation completes, restart Eclipse.
