无法加载地图。 无法联系Google服务器

Question

I got the SHA 1 certificate from the debug keystore .

Using that I generated the Google Map V2 Api key .

I extended Fragment Activity.

I used "com.google.android.gms.maps.SupportMapFragment" in my xml.

When I run this , it shows the following errors. "Failed to load map. Could not contact Google servers" Authorization failed.

Can anybody help me to recover from this issue.

Answer 1

On Google Api Console you need to go to services tab and ON Google Map Android API v2 . have you done it ?

Answer 2

Failed to load map. Error contacting Google servers issue with android google maps api v2 if you are getting this message with release api key - it means it is in debug mode. So export your app from eclipse and install the app.

Answer 3

It turns out that Google Play Console is probably signing your uploaded app with its own certificate and creating another SHA1 fingerprint different to the one you use for enable your API Map. Use the one that you can find in your Google Play Console>Release Management>App Signing setting up that one in your Google Developer Console
