I found many postings concerning this error, but none of the solutions worked for me.
I have project A, B, and C. Projects A and B are marked as library projects, project B imports project A as a library, and project C imports project B. When running project C from eclipse, I get the below error. "java.lang.IllegalArgumentException: already added: projectA/R;" Upon investigation, the generated R files for projects A and B are contained in the jar file create for project B, which is included in project C's android dependencies. Also, projects C contains R files for both project A and project B in its /gen folder. I assume this is causing the error, the R files appear twice on the classpath because they are in the android dependencies and the gen folder. If this is the cause, is there any way to fix it? -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
