performance - Unable to use retrofit android library getting error while compiling -

-

i using below code call api. have added custom key wont work: 

 string api_base_url="http://api.themoviedb.org/3/movie/popular?  api_key=adfasdfasd/";      retrofit retrofit = new retrofit.builder()             .baseurl(api_base_url)             .addconverterfactory(gsonconverterfactory.create())             .build();     moviesapi service = retrofit.create(moviesapi.class);     call<list<pictures>> pics = service.listpictures();

i have added below dependencies retrofit in gradle:

   compile 'com.squareup.retrofit2:retrofit:2.0.1'    compile 'com.squareup.retrofit2:converter-gson:2.0.2'

this interface 

   public interface moviesapi {      @get("results")      call<list<pictures>> listpictures();    }

i'm getting:

caused by: java.lang.illegalargumentexception: baseurl must end in /: http://api.themoviedb.org/3/movie/popular?api_key=adfasdfasd/ @ retrofit2.retrofit$builder.baseurl(retrofit.java:496) @ retrofit2.retrofit$builder.baseurl(retrofit.java:439) @ com.example.varunbehl.mymovies.mainactivity.oncreate(mainactivity.java:25) @ android.app.activity.performcreate(activity.java:6251) @ android.app.instrumentation.callactivityoncreate(instrumentation.java:1108) @ android.app.activitythread.performlaunchactivity(activitythread.java:2403) @ android.app.activitythread.handlelaunchactivity(activitythread.java:2510)  @ android.app.activitythread.-wrap11(activitythread.java)  @ android.app.activitythread$h.handlemessage(activitythread.java:1363)  @ android.os.handler.dispatchmessage(handler.java:102)  @ android.os.looper.loop(looper.java:148)  @ android.app.activitythread.main(activitythread.java:5459)  @ java.lang.reflect.method.invoke(native method) 

i have added / @ end of base url. solution?

the problem method of passing url:

you should pass url below:

string api_base_url="http://api.themoviedb.org/3/;

retrofit retrofit = new retrofit.builder()         .baseurl(api_base_url)         .addconverterfactory(gsonconverterfactory.create())         .build(); moviesapi service = retrofit.create(moviesapi.class); call<list<pictures>> pics = service.listpictures();

and interface this:

     public interface moviesapi {      @get("/movie/popular?{api_key}/results")      response getmovielist(@path("api_key") string api_key, callback<response> callback);

hope you.
