Retrofit: Attempted to deserialize a java.lang.Class. Forgot to register a type adapter?

[vyshnavkr]

This is regarding the StackOverflow question http://stackoverflow.com/q/39232330/6737655
The request is being done, but the response data seems empty. I guess it's due to an empty string fetched. Am I wrong?

[JakeWharton]

You have a list of Class in your model:

private List<Class> classes = new ArrayList<Class>();

This isn't supported by whichever serialization library you are using because you can't really serialize a class.

I am also receiving the same error when trying to POST some data.

You have a Class in your model:

Class<?> c = this.getClass();

This isn't supported by whichever serialization library you are using because you can't really serialize a class.

@nishantt12 as Jake told, you are using the word 'Class' in your model...generic words like Class, String, etc shouldn't be used like that... In my case, I had mistyped Classes as Class, which was the error..
@ JakeWharton thanx for clearing
