问题


I am using retrofit2 with Gson Converter.

my server response is :

     {
    "resonse": {
        "status": 200,
        "result": [
            {
                "video_id": "3c19979979",
                "video_title": "Sushil Kumar Modi press conference after serial bomb blasts at Modi rally in Patna",
                "video_description": "BJP at Patna serial blast in Bihar, Nitish government has stood in the dock. Former Deputy Chief Minister Sushil Kumar Modi said the blasts Narendra Modi were targeted. He said that Nitish Kumar look Modi as the enemy.<br />\r\n",
                "video_poster": "https://vbcdn.com/cdn/download/2013102913830306761810268995.jpg",
                "video_duration": "02:02",
                "video_category": "News/Politics"
    }
  ]}
}

ANd this is my pojo class:

public class ResponseVideoList implements  Serializable {

    @SerializedName("resonse")
    @Expose
    private Resonse resonse;
    private final static long serialVersionUID = -2645239251698186770L;

    public Resonse getResonse() {
        return resonse;
    }

    public void setResonse(Resonse resonse) {
        this.resonse = resonse;
    }

    public class Resonse implements Serializable {

        @SerializedName("status")
        @Expose
        private Integer status;
        @SerializedName("result")
        @Expose
        private List<VIdeoItem> result = null;
        private final static long serialVersionUID = 3604737417113897610L;

        public Integer getStatus() {
            return status;
        }

        public void setStatus(Integer status) {
            this.status = status;
        }

        public List<VIdeoItem> getResult() {
            return result;
        }

        public void setResult(List<VIdeoItem> result) {
            this.result = result;
        }
    }

}

VideoItem class:

 public class VIdeoItem implements Serializable
{

@SerializedName("video_id")
@Expose
private String videoId;
@SerializedName("video_title")
@Expose
private String videoTitle;
@SerializedName("video_description")
@Expose
private String videoDescription;
@SerializedName("video_poster")
@Expose
private String videoPoster;
@SerializedName("video_duration")
@Expose
private String videoDuration;
@SerializedName("video_category")
@Expose
private String videoCategory;
private final static long serialVersionUID = -7124444558733051869L;

public String getVideoId() {
return videoId;
}

public void setVideoId(String videoId) {
this.videoId = videoId;
}

public String getVideoTitle() {
return videoTitle;
}

public void setVideoTitle(String videoTitle) {
this.videoTitle = videoTitle;
}

public String getVideoDescription() {
return videoDescription;
}

public void setVideoDescription(String videoDescription) {
this.videoDescription = videoDescription;
}

public String getVideoPoster() {
return videoPoster;
}

public void setVideoPoster(String videoPoster) {
this.videoPoster = videoPoster;
}

public String getVideoDuration() {
return videoDuration;
}

public void setVideoDuration(String videoDuration) {
this.videoDuration = videoDuration;
}

public String getVideoCategory() {
return videoCategory;
}

public void setVideoCategory(String videoCategory) {
this.videoCategory = videoCategory;
}

}

the response is not fetched properly I think and I have also tried other answers like this but did not get any proper solution for this particular problem. the line 3 is "status": 200, this one but can't figure out the solution to this.

Retrofit client :

 OkHttpClient client = new OkHttpClient.Builder().addInterceptor(new Interceptor() {
            @Override
            public Response intercept(Chain chain) throws IOException {
                Request newRequest  = chain.request().newBuilder()
                        .addHeader("Authorization", "Bearer " + token)
                        .build();
                return chain.proceed(newRequest);
            }
        }).build();
       if (retrofit==null)
       retrofit = new Retrofit.Builder()
                .baseUrl(API_BASE_URL)
                .addConverterFactory(GsonConverterFactory.create())
               .client(client)
               .build();
        return retrofit;

API CLIENT :

  @Headers("Content-Type:application/json")
    @POST("video/list-video.php")
    Call<ResponseVideoList> getVideoListFromSearchText(@Body JsonObject jsonObject);

Remove every thing in ResponseVideoList class and just Put this; after that use this one class in your retrofit complete response will parse in this class 

public class ResponseVideoList  {


    /**
     * resonse : {"status":200,"result":[{"video_id":"3c19979979","video_title":"Sushil Kumar Modi press conference after serial bomb blasts at Modi rally in Patna","video_description":"BJP at Patna serial blast in Bihar, Nitish government has stood in the dock. Former Deputy Chief Minister Sushil Kumar Modi said the blasts Narendra Modi were targeted. He said that Nitish Kumar look Modi as the enemy.<br />\r\n","video_poster":"https://vbcdn.com/cdn/download/2013102913830306761810268995.jpg","video_duration":"02:02","video_category":"News/Politics"}]}

for helping you and find your issue use this library and see network logs and your response, then you can find your problem,

Add this to dependencies

 implementation 'com.squareup.okhttp3:logging-interceptor:3.12.0'

Now add it to your OkHttpClient

OkHttpClient client = new OkHttpClient.Builder()
       .addInterceptor(new HttpLoggingInterceptor().setLevel(HttpLoggingInterceptor.Level.BODY))
       .addInterceptor(new Interceptor() {
        @Override
        public Response intercept(Chain chain) throws IOException {
            Request newRequest  = chain.request().newBuilder()
                    .addHeader("Authorization", "Bearer " + token)
                    .build();
            return chain.proceed(newRequest);
        }
    }).build();

Now after call api you can see logs in logcat and finding your problem
