Hi,
I have a fatal error with my application demo. My application is a
simple MapView that shows a track. In this track I have add proximity
alerts at interesting points. When an alert is launched it shows a
Toast with information of this interesting point.
The application works correctly the first time that I run it, but if I
go to the home screen and run the application or I run another time
the application from Eclipse, the emulator is restarted. In DDMS
perspective I see these errors when this happen:

I see that occurs a ConcurrentModificationException but I don't know
where is the cause of the problem.
There is somebody that knows when / why this exception happens?.
Thanks.
