Forgive me if this is a duplicate, but the questions I find don't have an answer (I hope to simplify those questions).
Given two circles on a GoogleMap, how do I tell if they overlap and "smash" them into one image?
I have a lot of data points (~14K) and that many circles are not rendering well. Can they also be drawn just once, instead of 14k draw calls?
There is Google Maps API Clustering Utility. That should handle clustering your items for you.
And there is a SOF Question addressing the same issue and solutions as well.

In my project, I have to show more than 3000 overlays on the map, each of them got a unique position, which causes the program too laggy.. I guess the problem would be my program has to update or refresh the shape of each overlay individually for the screen. My idea is to combine the 3000 overlays together into one, but I still don't really know how to make it out.
Could anybody give me any ideas?
You may use 'Polygon', A 'Polygon' is like a poly-line. A series of connected coordinates in an ordered sequence, It also form a closed loop and define a filled region.
For more information, please view Official Google Documentation for Combining and visualising multiple data sources: https://developers.google.com/maps/articles/combining-data

I have checked a lot of SO questions but none really answered it.
I am looking to add google map with animated markers. This means sprite display 3-4 frames while fixed at the location and while moving.
I thought about using AnimationDrawable but that didn't work. The other 2 solutions I have in mind are:
1-Use marker.setPosition and marker.setIcon in a "loopy handler". Inclined to use this but for some reason I feel it is an over kill especially that I may have 100 Markers
2-Add SurfaceView on the map and draw bitmaps using LocationToPixels functionality of the map. But that may be cumbersoms when gestures are moving.
Do you recommend any of the above or even a new solution? Please justify why so it is not an oppinionated answer.
Thank you
lets say I have a situation where I have a few polygons ontop of eachother like this
is there a way to know what polygon is on-top aka the z-index of it? I didn't see anything in the docs but I was hoping I just missed it somewhere
Here it is - http://developer.android.com/reference/com/google/android/gms/maps/model/Polygon.html#getZIndex()
StackOverflow wants 30 characters out of me, so here they are.
Is there a way to check the visibility of an OverlayItem? So all I want to know is, if a overlay Item is shown on the map or already outside of the projection.
I'm afraid using the bounding box method of my original object which is represented by the overlay is a bit slow and since the MapView is doing this anyway...
(like hereHow can I determine if a geopoint is displayed in currently viewable area?)
Hopefully someone knows an answer.

I believe the best approach is the one you're already using (linking to). Perhaps you could look into ways to optimize the speed of it or reduce the amount of overlays you're using?
I have two markers on a map. The code is found on The developer site here. What I want to do is draw a line in between the two points. I have no idea what is to be done here. If I could get an example or tutorial site on this that would be great
-thanks
This question looks like it answers your question Drawing line between two points since the markers are set using geopoints I assume this will work for you
