it seems have not created own api key. first have generate api key using sha1 certificate keystore try.
if want generate sha1 certificate using keystore follow :
how can md5 fingerprint java's keytool, not sha-1?
to enable service , generating key visit : https://code.google.com/apis/console/
and make sure enable "google maps android api v2" in service tab of google api console.
