Im getting this error:
error: No resource identifier found for attribute 'showAsAction' in package 'com.myapp' add.xml /myapp/res/menu
But I cant figure out how to fix it. I didn't have this error on my previous computer which ran this package fine. I have looked at some fixes on here which so far haven't worked, for example, I cant change build path: here
maybe there is something else I should try? Thanks
