Google Map SDK unreasonable amount of memory used when using markers

Question

I have a huge project, that has dozens of screens.

I had to include google maps into the project and show some markers on it.
The maximum number of markers is around 600, spread all over the town.

When I call this mapView, it increases memory consumption from 19 to 240mb. This is not reasonable at all, the app starts flooding with memory warnings and crashes soon.

What can I do to fix that?

iOS version is 7.1 and Google Maps SDK is 1.8.1

Answer 1

Each marker on Google Maps view has a bitmap. Adding marker creates a new bitmap for it. I believe you have a limited types of markers and this, can share the bitmap along them.

Another strategy could be combining close markers into one metamarker and then, while user zoom-in - expand this group.

Good luck.
