The error is something like this:
[2014-11-02 15:43:23 - GoogleMap] C:\Users\woon\workspace\appcompat_v7\res\values-v21\themes_base.xml:79: error: Error: No resource found that matches the given name: attr 'android:colorPrimary'.


Anyone of you can help me solve it? I already struggle for it for few days~
