Hey these perspectives have gone (no longer available). How do I get them back? thanks
Assuming you have the correct versions of Eclipse, the ADT plugin, and the SDK installed:
Window > Open Perspective > Other > DDMS
The main android coding perspective is just the Java Perspective.
The standard Android perspective in Eclipse Juno (Version: 4.2.2) is at:
Window > Open Perspective > Java
More than a version of Eclipse may be conflicting. Just Change the workspace folder or choose a new one.
