Android - Map not showing up - "Ensure that the following Android Key exists:"

[RoDo777]

Map shows only "google" in the left button corner and the + and + buttons.
(e.g. Accounts -> choose an account -> MAP)

Build with this source, no package updated. Only changed to Android SDK V18, after it didnt work with V15 (gave this a try).

"Google Play services" are installed (Rev.22). Any other Google SDK package neccessary?
In Android 4.3.1 "Google APIs" also installed (V18 Rev.3)

Its seems to be the Verveta/debug.keystore is not valid (anymore).
Is it still active under the project "com.xamarin.Meetum" ?

Googled, found "deinstall app, clean and rebuild it", no change.
Tried it on a Samsung S3 and a Samsung S5, map not working.

I could try to put in a package name from me and build a debug.keystore file.
But normally it should work with the one here, right?

@stevenyix no need to hurry

You will need to get your own API key from google and update the keys. Here is our guide:

For whoever arrives here after me
Ensure you have an API key that isn't restricted for Google maps.
Go to google cloud platform dashboard.
Click and open the navigation menu.
Select google maps -> apis.
Select Google map API for android/ios (your required platform).
Click on enable.
