Android studio doesn't show google maps

Question

I am trying to display google maps on my app using Android Studio but even when I run just the default project of google maps it doesn't want to show the map. I have an API key and the necessary dependencies. I have inserted the meta-data into the manifest, but I still can't get a map on my app. Any help please?

Answer 1

1- In Android Studio project, you have to insert:

<meta-data
        android:name="com.google.android.geo.API_KEY"
        android:value="API_KEY GOES HERE"/>

2- In your Google Developer Console project you have to add certificate fingerprint and your application id.

Example:

BB:0D:AC:74:D3:21:E1:43:67:71:9B:62:91:AF:A1:66:6E:44:5D:75;com.example.android.mapexample

Explained in details in the following Google guide (Expand this part: Displaying the release certificate fingerprint ):
