@Klatschen your answer is right,in Retrofit2 the abstarct function has changed.

public final class StringConverterFactory extends Converter.Factory {
@Override
public Converter responseBodyConverter(Type type, Annotation[] annotations, Retrofit retrofit) {
    if (String.class.equals(type)) {
        return new Converter() {
            @Override
            public Object convert(ResponseBody responseBody) throws IOException {
                return responseBody.string();
            }
        };
    }

    return null;
}

@Override
public Converter requestBodyConverter(Type type,
                                                      Annotation[] parameterAnnotations, Annotation[] methodAnnotations, Retrofit retrofit) {
    if (String.class.equals(type)) {
        return new Converter() {
            @Override
            public RequestBody convert(String value) throws IOException {
                return RequestBody.create(MediaType.parse("text/plain"), value);
            }
        };
    }
    return null;
}
}
