Is map key generated in one machine cannot be used in another machine?

Issue

I have an Android map view application. In order to view the mapview, I have generated a map key and has able to view Google map. When I install the same apk in another machine's emulator, the map is not showing. Why so? Is it because of the map key?

Solution

Yes, because each debug.keystore of your ADT is associated with a unique Google Maps API key.

If you want to reuse this Google Maps API keys, simply copy you debug.keystore (locate in C:\Documents and Settings\YOUR_USERNAME\ .android) and replace your debug.keystore in other PC with this one.
