See #123 for original discussion.

I have now added in the ability for android to click on circles and ground overlays.

Cheers,

Merged into the issue123 branch by hand, then I will test.
Thank you

@lookaflyingdonkey Thank you for sending the pull request. Unfortunately, there is a bug.
When the polygon crosses over the dateline, rayCrossesSegment() function does not detect correctly.
Could you fix this?

const POINTS = [
  new plugin.google.maps.LatLng(38.548852, 139.784086),
  new plugin.google.maps.LatLng(32.548852, 139.784086),
  new plugin.google.maps.LatLng(18.332898, -157.921418),
  new plugin.google.maps.LatLng(24.332898, -157.921418),
];

map.moveCamera({
  'target': POINTS
});
map.addPolygon({
  'points': POINTS,
  'strokeColor' : '#AA00FF',
  'strokeWidth': 5,
}, function(polygon) {
  polygon.on(plugin.google.maps.event.OVERLAY_CLICK, function() {
    polygon.setFillColor("blue");
    alert("clicked");
  });
});

I'm trying to fix this using map.getProjection() now.

I finally managed to implement the OVERLAY_CLICK event for Polyline, Polygon, Circle, and GroundOverlay both Android and iOS.
Thank you for your encouragement, @lookaflyingdonkey 👍

For me this PR is not working on iOS. See this issue:
