This cannot be impossible: We have four developers on an android app that uses the google maps api. We have generated a maps key that works for the one who generated it. All the others, however, see a tiled MapView without the actual map. Since my debug.keystore was used to generate, I was suspecting that the others need the same keystore. So I moved it into the repository so that everyone has a copy of it now. Then, everyone pointed eclipse towards that keystore using the custom keystore setting in Android->Build. This still does not work. What do we have to do? Surely we don't have to each use our own key and keep replacing it after every pull?
This site (and the web in general) contains tons of information on Google Maps API keys, but none answered my question unfortunately.
Rather than trying to point Eclipse to a different keystore, just replace your local debug.keystore with the shared copy.
