Cpu over head for generate in android #43

Hi,

I am using CloudinaryService generate to generate url in my android app, and while profiling. I found this computation too costly in terms of cpu cycle and it is blocking my main thread. Is there any way to optimise it.

CloudinaryService.getCloudinary().url().transformation(transformation.fetchFormat("auto")).generate(name);

In some cases it takes 100 of milli seconds to just generate an url.
