Hello,
I have the same issue. Howver, I donot get the error frequently, but
on rare occassions.
The way my current code works is,
onMapReadyEvent(){
/*call some function wich in turn calls 3-4 functions and the last
function being
the one which fetches data (latitude and longitude) from database
and tries to instantiate markers.*/
}
As you see above, the markers initialization code is called only when
Map Ready event is fired.
Still, I am getting rare errors which is totally random.
Plz, give me the solution asap.
Regards,
Nayan.
