问题
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)

I followed this tutorial and I was able to fix it: https://www.youtube.com/watch?v=sJBlQv6IptQ. The video makes references to this tutorial: http://ramsandroid4all.blogspot.com/2016/01/google-maps-android-example-in-android.html.
In my case, what I did was to create a new project at https://console.developers.google.com/. I used Android apps for Application restrictions:
For the Restrict usage to your Android apps section, I had to provide a Package name and a SHA-1 certificate fingerprint. The Package name was in my app/build.gradle, specifically here:
applicationId "[my package name]"
The SHA-1 certificate fingerprint I found it from Android Studio by running signingReport:
The result included something like this:
Alias: AndroidDebugKey
MD5: [The value]
SHA1: [The value]
SHA-256: [The value]
Valid until: Wednesday, May 5, 2049

BUILD SUCCESSFUL in 0s
1 actionable task: 1 executed
16:31:44: Task execution finished 'signingReport'.
Now the map works correctly in my Android app:
UPDATE 1: To my surprise, the maps were working correctly only on the Android Studio Emulator but not on real Android physical devices. The solution was what I posted at https://stackoverflow.com/a/56307654/4242086.

I got the exact same symptoms when I moved the project to a new computer. My solution was to generate a new key based on the error message. The google_maps_api.xml file had an URL in a comment to generate key but that is a static thing, so after moving the project to a new computer I rewrote the URL to match the error message's version.
https://console.developers.google.com/flows/enableapi?apiid=maps_android_backend&keyType=CLIENT_SIDE_ANDROID&r=[put-the-thing-here]
Generated the key, put it in the XML file and it worked well.
