title: Traditional and Simplified Chinese languages not being picked up separately
body: <p>I am trying to pick up languages for my app. I have <strong>Traditional and Simplified Chinese</strong> as languages too. All other languages are working but in case of Chinese, where I have 2 values folders, named <strong>zh-rCN and zh-rTW</strong>, its not taking the languages. Where as if I rename any folder to just <strong>zh</strong>, it will start picking up that folder string. Also when I rename the folders to <strong>zh-CN</strong> and <strong>zh-TW</strong>, that is showing <strong>Error in res folder (AAPT Problem)</strong>.? 
  What can be done to show both languages separately.? </p>
