Hi friends i cant able to understand how to do this method please help me out. i am using the retrofit for the Json parsing its working well when the data is there but when there is no data in it then the response will be different like below where when i use the Volley then i used has method to know that data is there or not but i cant do that in the retrofit
{
"messae": "No Friends Found",
"status": "failure"
}
But When data is there the response will be like this
{
"friends": [
{
"username": "tester",
"user_id": "7",
"profile": "http://54.202.3.127/parallel_space/uploads/noimage.png",
"city": "kakinada",
"phone": "7894561231",
"status": "1"
},
{
"username": "tester",
"user_id": "9",
"profile": "http://54.202.3.127/parallel_space/uploads/http://54.202.3.127/parallel_space/uploads/pic-91488861905.jpg",

You have to check either success or failure from server. So you have to make another Model class and then check success or not
for e.g.
public class FriendsResposne implements Serializable {
@SerializedName("status")
private String status;
@SerializedName("messae")
private String message;
@SerializedName("friends")
private List< Friend_Request_adapter > friendsArr;
public String getStatus() {
return status;
}
public void setStatus(String status) {
this.status = status;
}
public String getMessage() {
return message;
}
public void setMessage(String message) {
this.message = message;
}
public List<Friend_Request_adapter> getFriendsArr() {
return friendsArr;
}
public void setFriendsArr(List<Friend_Request_adapter> friendsArr) {
this.friendsArr = friendsArr;
}
}
and then call like
private void frdreq_method() {
Constant.showloader(Friend_request.this);
Retrofit frq_reqretrofit = new Retrofit.Builder().baseUrl(Constant.url).client(Constant.okClient()).addConverterFactory(GsonConverterFactory.create()).build();
Api fre_req_api = frq_reqretrofit.create(Api.class);
Call<FriendsResposne> frq_req_call = fre_req_api.frdreqcall(Session.getUserID(getApplicationContext()));
frq_req_call.enqueue(new Callback<FriendsResposne>() {
@Override
public void onResponse(Call<FriendsResposne> call, Response<FriendsResposne> response) {
Constant.l(String.valueOf(response));
FriendsResposne fr = response.body();
if(fr.getStatus.equals("Success")){// check here success or not
List<Friend_Request_adapter> frdlistadapter = fr.getFriends();
friend_request_adapter.add(frdlistadapter);
}else{
Toast.makeText(this, fr.getMessage(), Toast.LENGTH_SHORT).show();
}
Constant.dismissloader();
}
@Override
public void onFailure(Call<FriendsResposne> call, Throwable t) {
Constant.l(t.toString());
Constant.dismissloader();
}
});
}
Let me know if you are facing any issue.
