I am having trouble adding my polygon with holes to my google map.

Here is all the code and it happens after the map is setup.

The problems seems to be that
addHoledoes not guard against a zero length array for holes. So, you should check to make sure you do not pass it a zero length array, because you are passing a zero-length array. Putting that guard in and logging your caught exceptions reveals your parsing is going awry in for your holes.Specifically,
is throwing —
So, you are trying to parse an array as a
double. I think your problem is that this line —should be something else. My previous suggestion got it to work, but I don’t think it was semantically correct, because it was repeating the same array as above. It is not clear from your
JSONwhere holes should be, but that it line is where you should start to look. Perhaps something like,
