Eclipse activity error?

Hi!
Just implemented my android project and the lib into eclipse but got this error_:


Any idea to solve it?
Thanks!

Refresh project folder in eclipse if you have been running cocos compile command before.

Try Project->Clean->Clean All

Oh yea, thanks for mention that I should compile, forgot that…
But do you know why this is happening then>

Thanks!

I will create a new topic about this error.

Wrong ant installation/configuration :slight_smile: probably you should point to executable of it in cocos config
