     <!-- Q: Why put style resources under values-v17/ ?
          A: Problem:
             1. paddingStart causes a crash on Galaxy Tab&Note b/8351339.
             2. So we wrote a build script(generate_v14_compatible_resources.py) to convert
                paddingStart to paddingLeft for pre-v17 (crbug.com/235118).
             3. However, style files are not overrided by the corresponding generated style files,
                but merged when we pass them to aapt unlike layout files.
 
             So we decided to keep style resources under values-v17/ so that it is not merged with
             the generated style resources under res_v14_compatibility/values/ (crbug.com/243952).
