title: Making a Snackbar Without a View?
body: <p>I want to show a snackbar as soon as the user opens the Google Maps activity, but the thing is that there's no views in the activity to use as the first parameter of the activity (in the <code>findViewById()</code> of <code>Snackbar.make()</code>). What do I put there?
  Here's the java class code:</p>
  
  <pre><code>public class MapsActivity extends FragmentActivity implements OnMapReadyCallback {
  
  private GoogleMap mMap;
  
  @Override
  protected void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.activity_maps);
  
      // Obtain the SupportMapFragment and get notified when the map is ready to be used.
      SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager()
              .findFragmentById(R.id.map);
      mapFragment.getMapAsync(this);
  }
  
  @Override
  public void onMapReady(GoogleMap googleMap) {
      mMap = googleMap;
      mMap.setBuildingsEnabled(true);
      mMap.getUiSettings().setZoomControlsEnabled(true);
      float cameraZoom = 17;
      LatLng location = new LatLng(43.404032, -80.478184);
      mMap.addMarker(new MarkerOptions().position(location).title("49 McIntyre Place #18, Kitchener, ON N2R 1G3"));
      CameraUpdateFactory.newLatLngZoom(location, cameraZoom);
      Snackbar.make(findViewById(/*WHAT DO I PUT HERE?*/), "Click the pin for more options", Snackbar.LENGTH_LONG).show();
  }
  }
  </code></pre>
  
  <p>Also, here is the activity xml code:</p>
  
  <pre><code>&lt;fragment xmlns:android="http://schemas.android.com/apk/res/android"
  xmlns:map="http://schemas.android.com/apk/res-auto"
  xmlns:tools="http://schemas.android.com/tools"
  android:id="@+id/map"
  android:name="com.google.android.gms.maps.SupportMapFragment"
  android:layout_width="match_parent"
  android:layout_height="match_parent"
  tools:context="ca.davesautoservice.davesautoservice.MapsActivity" /&gt;
  </code></pre>
  
  <p>And lastly, here's the stacktrace error:</p>
  
  <pre><code>08-03 11:42:21.333 3901-3901/? E/AndroidRuntime: FATAL EXCEPTION: main
