Consuming rest api using Retrofit

Question

I am working on android studio. I am trying to consume Rest API. Right now I am using Postman for doing my work.

Body Part

Header Part

Response

{
"data": [
    {
        "global_device_id": "982010",
        "msn": "002998002010",
        "relay_operate": "1"
    }
],
"message": "Auxiliary Relay Status",
"transactionid": "Abdfqwe332432423ti", 
"status": "1"
}

What I have done?

@POST("UIP/on_demand_parameter_read")
Call<UIPResponse> getRelayResponse(@Header("transactionid") String tid, @Header("privatekey") String pk, @Header("Content-Type") String ct,
                              @Body OnDemand onDemand);

OnDemand class

public class OnDemand {

@SerializedName("global_device_id")
@Expose
private String global_device_id;
@SerializedName("type")
@Expose
private String type;



public String getGlobal_device_id() {
    return global_device_id;
}

public void setGlobal_device_id(String global_device_id) {
    this.global_device_id = global_device_id;
}


public String getType() {
    return type;
}

public void setType(String type) {
    this.type = type;
}


public OnDemand(String global_device_id, String type) {
    this.global_device_id = global_device_id;
    this.type = type;
}
}

UIP Response Class

package com.thumbsol.accuratemobileassetsmanagament.model;



import com.google.gson.annotations.Expose;
import com.google.gson.annotations.SerializedName;

import java.util.List;


public class UIPResponse
{
@SerializedName("data")
@Expose
private List<Datum> data = null;
@SerializedName("message")
@Expose
private String message;
@SerializedName("transactionid")
@Expose
private String transactionid;
@SerializedName("status")
@Expose
private String status;

public List<Datum> getData() {
    return data;
}

public void setData(List<Datum> data) {
    this.data = data;
}

public String getMessage() {
    return message;
}

public void setMessage(String message) {
    this.message = message;
}

public String getTransactionid() {
    return transactionid;
}

public void setTransactionid(String transactionid) {
    this.transactionid = transactionid;
}

public String getStatus() {
    return status;
}

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

}

class Datum {

@SerializedName("global_device_id")
@Expose
private String globalDeviceId;
@SerializedName("msn")
@Expose
private String msn;
@SerializedName("relay_operate")
@Expose
private String relayOperate;

public String getGlobalDeviceId() {
    return globalDeviceId;
}

public void setGlobalDeviceId(String globalDeviceId) {
    this.globalDeviceId = globalDeviceId;
}

public String getMsn() {
    return msn;
}

public void setMsn(String msn) {
    this.msn = msn;
}

public String getRelayOperate() {
    return relayOperate;
}

public void setRelayOperate(String relayOperate) {
    this.relayOperate = relayOperate;
}

}

Retrofit Class

public static Retrofit getOnDemandRequest() {
    if (retrofitSignalStrength == null) {
        HttpLoggingInterceptor logging = new HttpLoggingInterceptor();
        logging.setLevel(HttpLoggingInterceptor.Level.BODY);
        OkHttpClient client = new OkHttpClient.Builder()
                .addInterceptor(logging)
                .connectTimeout(1000, TimeUnit.SECONDS)
                .readTimeout(1000,TimeUnit.SECONDS)
                .build();
        retrofitSignalStrength = new
                Retrofit.Builder().baseUrl(BASE_URL_STAT)
                .addConverterFactory(GsonConverterFactory.create())
                .client(client)
                .build();
    }
    return retrofitSignalStrength;
}

Then Finally In my button onClick I have done

 OnDemand onDemand = new OnDemand(global_device_id, type);

            Retrofit retrofit = RetrofitClient.getOnDemandRequest();
            RetrofitInterface retrofitInterface = retrofit.create(RetrofitInterface.class);
            Call<UIPResponse> call = retrofitInterface.getRelayResponse(transactionid, privatekey, content_type, onDemand);

            call.enqueue(new retrofit2.Callback<UIPResponse>() {
                @Override
                public void onResponse(Call<UIPResponse> call, Response<UIPResponse> response) {

                    boolean isSuccess = false;

                    if(response.isSuccessful())
                    {

                    }


                }

                @Override
                public void onFailure(Call<UIPResponse> call, Throwable t) {

                }
            });

Debugging

While debugging I am getting below log

   2020-08-12 14:06:29.551 18991-19117/com.thumbsol.accuratemobileassetsmanagament D/OkHttp: --> POST    http://port:IP/program/on_demand_parameter_read

I must be missing something that I don't know

Any help would be highly appreciated.

Hey, just add Log.d("AndroidNetworking", "response received: " + response.toString()); to onResponse() callback and Log.d("AndroidNetworking", "error occured: " + error.toString()); to onError callback. And make sure you added Internet Permission to AndroidManifest.xml file: developer.android.com/training/basics/network-ops/connecting — Mariusz Brona

But can your debugger access those Logs (stop at the line where the logs are)? — Mariusz Brona

Use @FormUrlEncoded

@Headers("Content-Type: application/x-www-form-urlencoded")
@FormUrlEncoded
@POST("UIP/on_demand_parameter_read")
Call<UIPResponse> getRelayResponse(
    @Header("transactionid") String tid, 
    @Header("privatekey") String pk,
    @Field("global_device_id") String deviceId,  
    @Field("type") String type
);

It does works but still I am unable to go inside the call.enqueue(new retrofit2.Callback<UIPResponse>()

Bek Over a year ago

It's because your json response model UIPResponse is wrong. Use jsonschema2pojo.org to create your model.

Faisal Qayyum Over a year ago

Yes I have created it with jsonpojo.

Faisal Qayyum Over a year ago

I have update my question please see my UIPResponse

Bek Over a year ago

Now your response model is correct. What error are you having?

If you havent, please add Internet permission in your manifest. You can look it up https://developer.android.com/training/basics/network-ops/connecting

Have you tried using other api? if not, please try it first. Just find some Dummy API in google. this is an example for you https://reqres.in/

I remember that okttp asks for secure api. i can see that yours is not using it. Please refer to this link https://developer.android.com/training/articles/security-config to trust all connection. You need to add it in your manifest but please read it first. Good luck

Did you initialize the library like it's described here? https://amitshekhar.me/Fast-Android-Networking/adding_fan_to_your_project.html

Also you can enable logging and check in logcat if it's executing the call:

Yeah I see, and when you debug you are getting onResponse or onFailure event? Maybe use logcat to print throwable or response

Accessing REST API is given in the Android developers guide. Try the example given here: https://developers.google.com/android/guides/http-auth
