5159-5192/teamtreehouse.com.iamhere E/Google Maps Android API﹕ Failed to load map. Error contacting Google servers. This is probably an authentication issue (but could be due to network errors).

I've 2 app. The one i've made from your blog following your tutorial. And the one i take from your github repo the refactored one.

When i start the copied one, it works. But when i start the refactored one it give me the error.

Don't know why. On the same phone by the way
