- Why do you need 200 design time Markers? It is possible to reuse Markers. Your app probably does not need 200 but it would need a list of 200 coordinates.
- you can instead, at an increased coding complexity, use run time Markers. You still need a List of your run time Markers.
Here is a way to generate LOTS of markers that might be advice appropriate for your Project.
"What you do depends on whether you use design time or run time markers; how you create them and how you use them in your app and why you need 200 (not the 5 you originally asked about).
