Maps

The Google Maps Android API v2 provides interactive maps for Android apps.
You must get a Google Maps API key. Follow the instructions. You must have a Google account.
Create a new project as explained in the Google instructions but use Empty Views Activity (as normal) so you can make it a Java project (which makes some extra work to remove the unnecessary main activity).
- Add a new Google->Google Maps View Activity
- Delete the default MainActivity and layout/activity_main
- Edit the manifest to make the MapsActivity the main one
- A MapFragment will have been added to the layout, e.g.,
```
    <fragment
        android:id="@+id/the_map"
        android:name="com.google.android.gms.maps.SupportMapFragment"
        android:layout_width="match_parent"
        android:layout_height="match_parent">
    </fragment>
```
- See the Map Object documentation for all the options.
- Add a line (might already be done automatically) in build.gradle dependencies
  implementation 'com.google.android.gms:play-services-maps:18.2.0'
