The resource compiler was changed in r14 so that the identifiers in a library project's R.java are no longer declared "final". This prevents the constants from being inlined into library bytecode, and instead forces these references to be resolved at runtime. In theory this should allow your library to continue to use R. values. Though, as explained in the r14 change docs, you won't be able to use resource ids in switch statements.
