TODO: Before you run your application, you need a Google Maps API key.

To get one, follow this link, follow the directions and press "Create" at the end:

https://console.developers.google.com/flows/enableapi?apiid=maps_android_backend&keyType=CLIENT_SIDE_ANDROID&r=00:ED:1B:E2:03:B9:2E:F4:A9:0F:25:7A:2F:40:2E:D2:89:96:AD:2D%3Bcom.natarajan.locationalarm

You can also add your credentials to an existing key, using these values:
Package name:
 00:ED:1B:E2:03:B9:2E:F4:A9:0F:25:7A:2F:40:2E:D2:89:96:AD:2D
SHA-1 certificate fingerprint:
 00:ED:1B:E2:03:B9:2E:F4:A9:0F:25:7A:2F:40:2E:D2:89:96:AD:2D

Alternatively, follow the directions here:
 https://developers.google.com/maps/documentation/android/start#get-key

Once you have your key (it starts with "AIza"), replace the "google_maps_key"
 string in this file.
