[android-developers] Re: memory issue with Google Maps API v2
Thanks Everyone for the reply. We are stress testing our app. We do it in all platform and seems like Android has a poor performance(or my implementation is poor). We do not do any special thing for iOS, but the all the 20/40K markers are rendered within 5-10 secs. Now I agree that the A6 chip can have better performance than the Qualcomm ones(i read an article about how that Samsung will boost its clock speed when it detects any benchmark apps). Leaving that aside, I have done everything that the Google IO talked about memory management, and not sure where I am wrong(or what am missing). On another note, If say i am using the app for sometime(to create lot of objects) and then connect the device to DDMS and 'cause GC', i see that it works fine, which means that those objects could have been collected. But the system is not able to collect them automatically. Any ideas?

Re: [android-developers] Re: memory issue with Google Maps API v2
Not sure about your actual requirement of placing thousand's of marker, as far i implemented, I have considered a radius based marker, like searching for Hotel,fuel stations in a radius of 10 miles or 5 miles.

[android-developers] Re: memory issue with Google Maps API v2
Have a look at how it is done in iOS. There you can have as many annotations as you want, and the system will only render the associated markers if they are actually on screen. In addition you want to limit the number of visible markers when you zoom out. Generally anything over 50 will be illegible on a phone screen. So have a round robin buffer of 50 annotations that you update based on the proximity to your current map center.
