I am trying to use retrofit with android, which is kind of forcing me to use gson.
I am trying to get the data from the payload["response"]["docs"][0]["web_url"] in my code.
Issue : the key getResponse(), from below model class, always gives me {}. Whats the right way to handle this in android? Also note, the getCopyright() & getStatus() are working fine.
I am also providing the sample payload.
I have the model class like this :
public class ArticleSearchResponseModel {
#SerializedName("status") private String status;
#SerializedName("copyright") private String copyright;
#SerializedName("response") private JSONObject response;
public String getStatus() {
return status;
}
public String getCopyright() {
return copyright;
}
public JSONObject getResponse() {
return response;
}
public void setStatus(String status) {
this.status = status;
}
public void setCopyright(String copyright) {
this.copyright = copyright;
}
public void setResponse(JSONObject response) {
this.response = response;
}
}
My payload :

Before start, I'm not familiar with retrofit.
If you want serialize/unserialize json to pojo, you better make pojo object.
class Response {
Meta meta;
List<Docs> docs;
}
class Docs {
String webUrl;
Mutimedia multimedia;
...
}
The issue the key getResponse(), from below model class, always gives me {} happens because gson cannot determine proper object to convert json to plain old java object.
In order to make your Response model class use http://www.jsonschema2pojo.org/.
Making POJO simple
you no need to make exact structure in model
you can go ahead with your code just need small change
Use
#SerializedName("response") private JsonObject response;
instead of
#SerializedName("response") private JSONObject response;
and in the import
import com.google.gson.JsonObject;
I'm using the LinkedIn Android SDK downloaded from here (version 1.1.4) and have set up authentication already like this:
liSessionManager.init(activity,
Scope.build(Scope.R_BASICPROFILE, Scope.R_EMAILADDRESS), authListener);
and everything works fine, but when I want to get the profile data, returned json is missing fields like summary in job positions and general summary for the given profile.
The request is made like this:
apiHelper.getRequest(activity, GET_LINKED_IN_PROFILE_URL, apiListener);
where GET_LINKED_IN_PROFILE_URL is https://api.linkedin.com/v1/people/~:(id,first-name,last-name,email-address,formatted-name,headline,location,industry,current-share,num-connections,num-connections-capped,summary,specialties,positions,phone-numbers,public-profile-url,picture-url,picture-urls::(original))?format=json.
The response is as follows:

Which shows that the Android SDK's response is missing some job positions and a summary for a profile.
It turned out LinkedIn is not returning fields that have no value. If you don't setup a summary in your profile, then there won't be a field named summary in the response. (Don't expect anything like "summary" : null)
Additionally only first position is returned for a given profile while using r_basicprofile scope. It's confusing since this one profile is returned in the positions array.
based on https://developer.linkedin.com/docs/fields/basic-profile :
Positions - An object representing the member's current position.
See Position Fields for a description of the fields available within this object.
The reason why the API Console's response was having all job positions is because it asked for r_fullprofile scope while authenticating
