android - Bug with Override annotations in Eclipse

Question

I have a annoying problem with @Override annotations in Eclipse. Often when i import working projects on a new PC, Eclipse marks some of the @Override annotations as wrong. If i remove the annotations everything is fine and Eclipse also indicates that the methods are overriding the parents methods but adding the Override annotation causes the error again. I am currently working on an Android project so it might be a problem with Android and not with Eclipse..

This is most likely because you are switching between Java 1.5 and Java 1.6. In 1.5 you couldn't mark interface implementations with @Override, but you can in 1.6.

A quick Google search turned up this good explanation of the difference in this annotation between the two versions: http://www.techienuggets.com/CommentDetail?tx=38155

Semantics of @Override is different in JDK 1.5 and JDK 1.6. In JDK 1.5, the @Override annotation is not allowed for implementations of methods declared in an interface, while they are allowed in JDK 1.6. For more information, see:

It is fact that the description of the Override annotation was not updated in the JDK API docs. This has been reported as a bug:
