android api portability error

Issue

I have a little problem. I have created an android api that uses google maps(mapview) on my pc with eclipse and the android emulator. Everything seems to be running fine on my pc, but when I try to install and run the same api on my laptop everything runs great, except that when I navigate to the activity using the mapView, the map shows grey with grids on the screen and not as a map. Could the problem be, that because I am running the api on a different pc, I should create a new api key to use? In another topic, I have seen that a possible solution could be, to change the version of the java compiler to the one that the program was originally compiled. I tried this too to no effect. Any help would be useful.

Solution

The Google Maps API key corresponds to your app key, when running the app locally without signing it with a keystore the app is signed by the eclipse debug key (which is different for every computer), so you need to create a new API key for every debug keystore you're using. To sum it up, you need a different API key for each development computer and off-course another API key for your release keystore.
