Google Map on Android do not load

since 2 different machines have two different debug keys, you should copy your old debug.key file from previous machine android sdk to new machine android sdk folder or else you should go to new map api key with new machine debug.key file

go to your GoogleMapsAPI credential and input your package along with your android keyhash.

Make sure you have enabled Google Maps Android API v2 in the APIs list on your project's Google page.

This generated the same error you got. I wasted a couple of hours with this so hopefully it will save someone's time in the future.
