I'm trying to open an Android project that a close associate has developed using IntelliJ. He strongly recommends this IDE, whereas I'm an Eclipse user - but it sucks, so I want to switch.
However, I just cannot get the Android project to build, all I get is 100 'Package R does not exist' or 'cannot find symbol class R' errors (basically everywhere this R file is used). The R.java file is being generated, I can open it up and it looks fine - what am I doing wrong? Any ideas on how to troubleshoot this problem?
