You haven’t posted the LogCat output, so it’s hard to know why it is crashing, but it’s probably because you’ve left the comment in there for the Maps key.

Here’s a tutorial explaining how to get a (free) Google Maps API key, to insert into your app. Note that you generally need TWO. One is for your app when it’s in debug mode (using the debug signing key). the other is for when you use a production version of the app (signed with a production signing key).
