java.util.UnknownFormatConversionException #1734
Description
I use rest like this:
@Rest(rootUrl = "http://xxx.com",converters = GsonHttpMessageConverter.class)
public interface APIService {
@Get("/app/api/json.php?param={%22limit_a%22:0,%22limit_b%22:10,%22flag%22:6,%22m%22:101}")
MyBean getObj();
}Error:(16, 12) 错误: Something went wrong: Unexpected error in AndroidAnnotations 4.0.0!

this is two issues in one run.
{}is uesed to detect an url variable. therefore your json string is assumed to be an url varialbe (and as your method does not have a parameter the error should have been printed - but caused this exception due to the AA bug)dodgex commentedon Mar 21, 2016
correction to 1) due to the content of your json and therefore the with
{}detected url variable name the json (more precise the%22inside) causes the exception due to the use ofString.format()with that string being part of theformatparameter...@WonderCsabo any idea if we can fix that?
WonderCsabo commentedon Mar 21, 2016
Well, there are two considerations here:
{}s in the url, but sometimes they are not url variables, as we seen here. Maybe we should not validate from this direction? Maybe we should check what Retfofit does.dodgex commentedon Mar 21, 2016
it cant escape the string in this case as it is concatenated to the String that is used as
formatparameter.WonderCsabo commentedon Mar 21, 2016
Yes, we should introduce some new api for that.
dodgex commentedon Mar 21, 2016
it would be good to have an override of
addErrorthat allows to pass parameters to be passed toString.formatbe used to do the formattingWonderCsabo commentedon Mar 21, 2016
Yes, we should add an overload, i agree!
dodgex commentedon Mar 21, 2016
yeah... overload is what i meant no idea why i wrote override. sorry :D

@WonderCsabo @dodgex @linwoain Is this bug supposed to be an enhancement then? Could you please mark it accordingly? Thanks!
WonderCsabo commentedon Dec 30, 2016
@gauravsak i labelled this issue.
