unfortunately app has stopped working, first android app, using google maps api

unfortunately app has stopped working, first android app, using google
maps api

Making my first android app, just followed the instructions on the google
maps api version 2 official site step by step. Did everything as it said.
Including getting the api key, making emulators, installing all the SDK,
google services etc.. Not sure why I get an error message as soon as I
attempt to start the application: "Unfortunately googleMaps has stopped
working".
Can't say the error output is very helpful to me as this is my first
android app. I could use some guidance.
Here is LogCat output:
