OkHttp in android for making network requests

Question

What I am trying to do::

I am trying to learn the usage of Okhttp for making networking calls in android

---

What I have done::

• I have read their documentation here
• I have downloaded and added the JAR in the project
• I am using their sample code from here

---

MyCode::

MainActivity.java

import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
import com.squareup.okhttp.OkHttpClient;
import com.squareup.okhttp.internal.http.Request;
import com.squareup.okhttp.internal.http.Response;
    public class MainActivity extends Activity {

        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_main);

             Request request = new Request.Builder()
                .url("https://raw.github.com/square/okhttp/master/README.md")
                .build();

            Response response = client.execute(request);

            Log.d("ANSWER", response.body().string());

        }

    }

Error i am facing::

In the line Response response = client.execute(request); I am getting error as :

client cannot resolved to a variable

How to resolve this !

---

{Update}

public class MainActivity extends Activity {

    OkHttpClient client = new OkHttpClient();


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

         Request request = new Request.Builder()
            .url("https://raw.github.com/square/okhttp/master/README.md")
            .build();

        Response response = client.execute(request);

        Log.d("ANSWER", response.body().string());

    }

}

Now I am facing error as :

in the line Response response = client.execute(request); as The method execute(Request) is undefined for the type OkHttpClient

Answer 1

The method execute(Request) is undefined for the type OkHttpClient

You are getting this exception because there is no such method ie.execute(Request) for OkHttpClient. Rather it is invoked on Call object which is obtained using OkHttpClient object as follows:

  Call call = client.newCall(request);
  Response response = call.execute();

I think you should be using

Response response = client.newCall(request).execute();

instead of Response response = client.execute(request);
