Google Maps Android API v2: Failed to Load Map. Could not contact Google Servers

Question

I'm trying to use Google Maps Android API v2, and I have already created the SHA1 key from my release cert.

I've read the comments from here and have made everything right, including the permissions for READ_GSERVICES which wasn't stated in Google's instructions here

However I'm still having the error of

E/Google Maps Android API(12334): Failed to load map. Could not contact Google servers.

Can anyhow enlighten me if I still have something left out?

I've included this as well:

<permission
      android:name="com.example.permission.MAPS_RECEIVE"
      android:protectionLevel="signature"/>
    <uses-permission android:name="com.example.permission.MAPS_RECEIVE"/>

and

<meta-data
        android:name="com.google.android.maps.v2.API_KEY"
        android:value="my_api_key"/>

in my applcation tag.

UPDATE: Just Managed to remove that error, realied that I typed my READ_GSERVICES wrongly.

However, now I'm having this problem:

01-24 16:58:08.628: E/Google Maps Android API(28025): Authorization failure.

What is causing this problem? my SHA1 is obtained from my release cert, is that wrong?

Answer 1

Did you solve the problem? May be this is the problem ->

Wrong service was enabled. Make sure the "Google Maps Android API v2", not "Google Maps API v2" is enabled and re-generate the API key. (https://stackoverflow.com/a/13805807/1300982)

If this is the problem, do not forget to Regenerate the API Key.
