google-maps-markers

Trying to make a small Android app that shows the locations of people as Google Maps markers. when the user presses a button to appear on the map, the app retrieves the users data from the Firebase JSON and shows the users on the map in real time. If a user moves, the marker moves with him (removed and recreated when his location changes). Everything works great, except that when the user presses to leave the map, his marker remains in all the other phones even though it's deleted from the Firebase JSON. Can anyone explain how to fix this problem? My code for retrieving the users and create

I have a bounds to a place and created a polygon of that place. How can I generate a random point inside the bounds of that polygon? One way of doing it. This will calculate the bounds of the polygon, then guess a random point inside that bounds, if the point is contained by the polygon, it will put a marker there. // calculate the bounds of the polygon var bounds = new google.maps.LatLngBounds(); for (var i=0; i < polygon.getPath().getLength(); i++) { bounds.extend(polygon.getPath().getAt(i)); } var sw = bounds.getSouthWest(); var ne = bounds.getNorthEast(); // Guess 100 random points inside

I'm trying to Spiderfy my markers and adding listeners to them. The Spidefying works fine that means I get the overlapping markers spiderfied but the problem is that I can't seem to figure how to add listeners to these markers. In other words I have tried the following: Putting the oms.addListener() in a loop. This way, upon clicking on a marker would open all infoWindow s on the same marker which isn't delightful. Putting the oms.addListener() outside the loop like the example on the OMS Git repo. https://github.com/jawj/OverlappingMarkerSpiderfier/blob/gh-pages/demo.html . This way all the
