Gson from JSon OutOfMemmoryError

I have a web service that returns a image in Base64 format. The body response, as Fiddler says has a Content-Length: 383143.

The response is like: {... two strings... and... ImageBase64":"iVBORw0KGgoAAAANSUhEUgAAAZAAAAGQCAYAAACAvzbMAAAAAXNSR0IArs4c.....}

I request data from the web service and I receive it in a string format. When I try the following:

LargeImage trackLargeImage = new Gson().fromJson(webServiceStringResponse, LargeImage.class);

It takes a while and I get this error:

n.JsonParser.parse(JsonParser.java:54)

n.JsonParser.parse(JsonParser.java:54)

If the image is a not complex, then it works fine, if the image is complex the out of memory error occurs. Any ideas ? Thank you for your time.
