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

Here's another thing to watch out for: I registered the same SHA1 hash with two different API projects. (Yes, I know this is silly, but I was experimenting with different ways to fix a problem.)

I mention this here, because you may have everything properly configured but you have MORE THAN ONE key for your project on Google's API console. (Here's hoping this silly mistake doesn't happen to you.)

Answer 2

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.

Answer 3

As this time you are using

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

are you sure that you package name is com.example, if not then replace com.example with actual package_name

Answer 4

I had the same problem. I was using google maps api v1 key. I swithced it with google maps android api v2 key and problem solved.

Answer 5

Make sure a different key is generated for different applications..

Answer 6

I had the same problem and nothing worked. Then I have found Google Play Services in the Application Manager and cleared the data. Suddenly new API key started working!

Answer 7

If you are using Xamarin remember to create the API key using the debug.keystore stored in:

Windows users: C:\Users[USERNAME]\AppData\Local\Xamarin\Mono for Android\debug.keystore

OSX: Users/[USERNAME]/.local/share/Xamarin/Mono for Android/debug.keystore
