Answer 1

I had the same problem and I did the mistake to only add one of the 2 following tags. Note that you are also missing one of these two

        <meta-data
            android:name="com.google.android.geo.API_KEY"
            android:value="<YOUR VALUE>"/>
        <meta-data
            android:name="com.google.android.gms.version"
            android:value="@integer/google_play_services_version" />

The actual error is really misleading, as you might be thinking of some API level UI issue.

Answer 2

Make sure you have declared the fragment in your layout. Like following.

<fragment
          android:id="@+id/map"
          android:layout_width="match_parent"
          android:layout_height="match_parent"
          android:name="com.google.android.gms.maps.MapFragment"/>

Also that you have added Google Play services library in your project.
