Google Maps Android API: Authorization failure. Ensure that the "Google Maps Android API v2" is enabled. Ensure that the following Android Key exists

Question

I am getting this error:

E/Google Maps Android API: Authorization failure.  Please see https://developers.google.com/maps/documentation/android-api/start for how to correctly set up the map.
E/Google Maps Android API: In the Google Developer Console (https://console.developers.google.com)
Ensure that the "Google Maps Android API v2" is enabled.
Ensure that the following Android Key exists:
    API Key: [The key...]
    Android Application (<cert_fingerprint>;<package_name>):

Instead of the map working correctly, this is what I see:

In my app/build.gradle, I have this:

implementation 'com.google.android.gms:play-services-base:16.1.0'
implementation 'com.google.android.gms:play-services-analytics:16.0.8'
implementation 'com.google.android.gms:play-services-awareness:16.0.0'
implementation 'com.google.android.gms:play-services-cast:16.2.0'
implementation 'com.google.android.gms:play-services-gcm:16.1.0'
implementation 'com.google.android.gms:play-services-location:16.0.0'

play-services-location is what I need for the Google Maps, correct? I was looking at the list at https://developers.google.com/android/guides/setup and I assume that Google Location and Activity Recognition - com.google.android.gms:play-services-location:16.0.0 is what I need for Google Maps. Is this correct?

UPDATE 1: I already have Maps SDK for Android enabled:

The error says: Ensure that the "Google Maps Android API v2" is enabled.. Is it referring to the Maps SDK for Android that I am showing in the screenshot in this UPDATE 1?

UPDATE 2: I have Maps SDK for Android enabled:

When I click the MANAGE button, I can go to the section to configure credentials that I showed in UPDATE 1.

UPDATE 3: I see the Map displayed correctly on all versions of Android on the Emulator. But on physical devices, the map never shows up. I see the Google logo and the red balloon, but now the map when I run the app on physical phones. Only on the Emulator everything works. Any ideas why?

UPDATE 4: See my solution at https://stackoverflow.com/a/56307654/4242086.

Hey I had the same problem today!,I solved it very easy for first you have to go https://console.developers.google.com and enable the android SDK maps and then create the api key, return in xamarin go to your manifest and add the google maps api key

https://docs.microsoft.com/it-it/xamarin/android/platform/maps-and-location/maps/obtaining-a-google-maps-api-key?tabs=windows

This is the documentation (I typed this fast because am on mobile now sorry)
