WHY ItemizeOverlay produce ArrayOutOfBoundException Not Always Occure This issue?

Question

I am showing POI's List on google map as:-

1- User Zoom-In or Zoom-Out a webservice call which responce xml of properties in perticular location.

2- After getting property we have to filter those properties which have same lat,long and show those number on bubbles on map(say 3 list have same lat ,long put that list into a arrayList and show on bubbles 3).

3- but when I seldom not always I am zooming map following Exception occurs:

Anyone help me I unable to solve this issue till now near about 10 hours I have been spends plaese see this..

Answer 1

After spend more time I have reach that My problem due to this post:- Async Task throw ConCurrent Modification Exception?

Answer 2

java.lang.ArrayIndexOutOfBoundsException: index=0 length=0 means that you are trying to access an element of an ArrayList when the size is zero. Go back through your code and make sure you're not trying to access an empty list.

EDIT:

Okay, I think I know what you're problem is. I think you're using createItem to try and add overlays to your ItemizedOverlay. This function is poorly named, and does not actually create an item. It simply returns an item from your array of OverlayItems. You need to use GoogleMapViewOverlay.addOverlay(OverlayItem) to truly add an OverlayItem to the map. Try creating a couple test Overlays with random coordinates and see if that works out. Remember to stop using createItem() and start using addItem(). If this isn't your problem then post all of of your code and maybe we can help you out a little better.

Answer 3

I'm not sure at what point in your code the error is arising, but you could try changing:

if (size == 1) {
} else {
}

to:

if (size == 1) {
} else if (size > 1) {
}

That might get rid of your ArrayIndexOutOfBoundsException
