Type R is already defined error

Import a project today. The system prompts "type R is already defined error, Google, stackoverflow" during compilation and finds a solution,

"The type R is already defined"

That's the message you get in eclipse if you try to build the funambol Android sync client. reason is that you have checked two builders that try to generate the same class. you just have to uncheck the Java-builder from project-> properties-> builders. then the application even works fine in the emulator.

When Java-builder is removed, a warning occurs. After the compilation is finished, the compilation is OK. However, the wierd error occurs during the debugging process, such as clean and rebuild, which does not take effect,

All go crazy ~ @ [Email protected] # [email protected] # $. Later, I remembered the warning and decided to restore the original settings. Then google found that there was an R under the src directory. caused by Java, Clean & rebuild, test OK after Delete.
