Android Map does not work when apk is not installed from Eclipse

Issue

In a project, when I install the app on a handset directly through the Eclipse IDE, I can see the Map functioning perfectly.

But if I send the apk to someone through email and they install it on the device, altough the app works they are not able to see the map but only a blank grid!

We already have the MapKey in the project. For a non-market app, how can I show the map if the app is not installed through the Eclipse IDE on my system?

Solution

Each api key is tied to that certificate. When you run a project in eclipse, it uses your debug keystore. When you export it, you most likely are using a different keystore, so your maps api key is no longer valid. Take the keystore you used to signed the exported apk and get a new api key. You'll need to swap the map api key back and forth when you are developing and releasing your app. Hope that helps.
