android - java.lang.IllegalArgumentException: 'retrofit2.Response' is not a valid response body type. Did you mean ResponseBody? -


my question similar retrofit 2.0 beta 4 response illegalargumentexception answer didn't me.

i'm migrating retrofit 1.9 2.0.2. i'm registering app messaging once launches.

    /**      * synchronous method register gcm token on backend server      *      * @return true, in case of success response, false otherwise.      */     public boolean registergcmtoken()     {         ...          try         {             call<response> call = mservice.registergcmtoken(sessionid, this.additional_query);             final response response = call.execute().body(); // <<< error points here             final defaultresponse defaultresponse = defaultresponse.newinstance(response);             return defaultresponse.issuccess();         }         catch (ioexception ignored)         {          }          return false;     }

my interface looks like:

    @get("my/url")     call<response> registergcmtoken(@header(constant.header_wildcard) string accesstoken,                     @querymap map<string, string> additionalquery);

once launch app i'm getting error:

java.lang.illegalargumentexception: 'retrofit2.response' not valid response body type. did mean responsebody?

and points line mentioned above.

my newinstance method looks like:

    public static final defaultresponse newinstance(final response response)     {         final defaultresponse defaultresponse = new defaultresponse();         if (response != null)         {             defaultresponse.status = response.code();         }          return defaultresponse;     }

so see, need know http status code. changing response generic responsebody i'm not able http status code. so, recommendation? thanks

what got while reading answers post suggested instead of :

@get("my/url")     call<response> registergcmtoken(@header(constant.header_wildcard) string accesstoken,                     @querymap map<string, string> additionalquery);

try :

@get("my/url")     call<responsebody> registergcmtoken(@header(constant.header_wildcard) string accesstoken,                     @querymap map<string, string> additionalquery);

because getting responsebody , not response here :

        final response response = call.execute().body();

like did : how can handle empty response body retrofit 2?

scala - 'wrong top statement declaration' when using slick in IntelliJ -

Image
i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
