Dear All, I have a situation where I need to tell users where the nearby ATMs are located. The problem is if the bank has 10000 ATMs.
When I use Maps for web programmings, I usually only load ATMs on visible area. When user do panning or zooming out, I request back-end server to provide more ATMs and redraw all overlay items. But I don't think we can use this technique on mobile device. If I use technique from https://developers.google.com/maps/documentation/android/hello-mapview, I get a performance hit. What is the best way to handle this? We know that there are some concerns: 1. Loading all ATMs will eat memory a lot. 2. Loading ATMs on visible area may eat a lot of data connection as users do panning. (I don't know either how to get the visible coordinate border) I've done some experiments. Loading 1000 overlay items (ATMs) (1000 x itemizedOverlay.addOverlayItem(anAtm); and 1 x populate()) has consumed 5 seconds. Is there any best practice in doing this? I really hope Google would give developers the best practice. I've also posted this question here http://stackoverflow.com/questions/12196158/best-practice-in-handling-huge-overlay-items-on-android-maps Thanks -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
