A `HttpStack` implementation for Volley that uses OkHttp as its transport.

OkHttpStack.java

import com.android.volley.toolbox.HurlStack;
import com.squareup.okhttp.OkHttpClient;
import java.io.IOException;
import java.net.HttpURLConnection;
import java.net.URL;

/**
 * An {@link com.android.volley.toolbox.HttpStack HttpStack} implementation which
 * uses OkHttp as its transport.
 */
public class OkHttpStack extends HurlStack {
  private final OkHttpClient client;

  public OkHttpStack() {
    this(new OkHttpClient());
  }

  public OkHttpStack(OkHttpClient client) {
    if (client == null) {
      throw new NullPointerException("Client must not be null.");
    }
    this.client = client;
  }

  @Override protected HttpURLConnection createConnection(URL url) throws IOException {
    return client.open(url);
  }   
}

it seems to need com.squareup.okhttp.OkUrlFactory.java, and change the createConnection(URL url) like this:
@OverRide protected HttpURLConnection createConnection(URL url) throws IOException {
return new OkUrlFactory(client).open(url);
}

@JakeWharton @s1rius

maybe differences of new version.

I made a new class because I want to use cache from okhttp, not volley.
(Volley does not support syncronous request)

And this is for okhttp 2.0

https://gist.github.com/ceram1/8254f7a68d81172c1669

How can I use Volley and OkHttp 2.0 to accept my self signed Certificate? I am begggining to use OkHttp 2.0 alone inside an Async Task and no problems, but I don't know how to make it work with Volley....Anybody knows?

With the most recent OkHttp I had to change to:

import com.android.volley.toolbox.HurlStack;
import com.squareup.okhttp.OkHttpClient;
import com.squareup.okhttp.OkUrlFactory;

import java.io.IOException;
import java.net.HttpURLConnection;
import java.net.URL;

/**
 * An {@link com.android.volley.toolbox.HttpStack HttpStack} implementation which
 * uses OkHttp as its transport.
 */
public class OkHttpStack extends HurlStack {
    private final OkUrlFactory mFactory;

    public OkHttpStack() {
        this(new OkHttpClient());
    }

    public OkHttpStack(OkHttpClient client) {
        if (client == null) {
            throw new NullPointerException("Client must not be null.");
        }
        mFactory = new OkUrlFactory(client);
    }

    @Override protected HttpURLConnection createConnection(URL url) throws IOException {
        return mFactory.open(url);
    }
}

Since open was relocated to the OkUrlFactory (which is part of okhttp-urlconnection)

@imminent , it's nice you have implement OkHttp With Volley but i want to know how to use this Custom OkHttpStack class that you have implement ? (i am Newbie)

how can i get the jar file with this file added in?

To get @imminent's code to work, you need to add

compile 'com.squareup.okhttp:okhttp-urlconnection:1.6.+'

to your build.gradle

Does it make sense? (In order to avoid "OkHttp changes the global SSL context, breaks other HTTP clients" square/okhttp#184 )

/**
 * An {@link com.android.volley.toolbox.HttpStack HttpStack} implementation which
 * uses OkHttp as its transport.
 */
public class OkHttpStack extends HurlStack {
    private final OkUrlFactory mFactory;

    public OkHttpStack() {
        this(new OkHttpClient());
    }

    public OkHttpStack(OkHttpClient client) {
        if (client == null) {
            throw new NullPointerException("Client must not be null.");
        }

        try {
            SSLContext sslContext = SSLContext.getInstance("TLS");
            sslContext.init(null, null, null);
            client.setSslSocketFactory(sslContext.getSocketFactory());
        } catch (Exception e) {
            throw new AssertionError(); // The system has no TLS. Just give up.
        }

        mFactory = new OkUrlFactory(client);
    }

    @Override
    protected HttpURLConnection createConnection(URL url) throws IOException {
        return mFactory.open(url);
    }
}

Neither OkHttpClient nor OkUrlFactory has a method named open now. None of the above implementations work with the latest versions of OkHttpClient.

@mehmet6parmak
You need to add okhttp-urlconnection
https://repo1.maven.org/maven2/com/squareup/okhttp/okhttp-urlconnection/2.2.0/

I am sorry guys, but how do I add the url connection you mentioned? I am using the latest Android Studio IDE.

I guess I should explain what I am trying to do:

• All I am trying to do is to be able to us PATCH to send data over to a server. I haven't been able to do that with Volley for the past 2 days... and I am pretty much hitting my head into the wall right now :(

I followed previous comments on how to use OkHttpStack implementation. I did all that but I am getting this error when I run my app in the emulator:

java.net.ProtocolException: Unknown method 'PATCH'; must be one of [OPTIONS, GET, HEAD, POST, PUT, DELETE, TRACE] which is something that one other person got too. However, I don't understand how to solve this problem.

Can you please help?

Thanks

This implementation of OkHttpStack works with OkHttpClient v2.3.0 (doesn't use open(url) method):
https://gist.github.com/bryanstern/4e8f1cb5a8e14c202750

@imminent version still works with these dependencies in gradle:

compile 'com.squareup.okhttp:okhttp:2.4.0'
compile 'com.squareup.okhttp:okhttp-urlconnection:2.4.0'

then you just have to init your RequestQueue with:

myRequestQueue = Volley.newRequestQueue(context, new OkHttpStack())

@JakeWharton i' m your fan!!

Any update on how we can use Volley with okhttp3 ?

Any update on how we can use Volley with okhttp3 ?

Yep! you can look here : https://gist.github.com/SylvainHocq/36d6b17e53c7004f6ae59e689ec0862f

client.open(url);

open method is not working,
Is there any working alternative for this?.

@sushant4anshu, yes,
That one works for me

add these libraries to gradle file
compile 'com.squareup.okhttp3:okhttp:3.9.0'
compile 'com.squareup.okhttp:okhttp-urlconnection:1.6.+'

then :

/**
* An {@link com.android.volley.toolbox.HttpStack HttpStack} implementation which
* uses OkHttp as its transport.
*/

  private class OkHttpStack extends HurlStack {
        private final OkUrlFactory mFactory;

        public OkHttpStack() {
            this(new OkHttpClient());
        }

        public OkHttpStack(OkHttpClient client) {
            if (client == null) {
                throw new NullPointerException("Client must not be null.");
            }
            mFactory = new OkUrlFactory(client);
        }

        @Override protected HttpURLConnection createConnection(URL url) throws IOException {
            return mFactory.open(url);
        }
    }

while creating Volley Queue:
mRequestQueue = Volley.newRequestQueue(mCtx.getApplicationContext(), new OkHttpStack());

What is the advantage of using OkHttp as transport for Volley?

OkUrlFactory is gone

It was deprecated in December 2015 and deleted in March 2019. You should use this instead:
https://gist.github.com/bryanstern/4e8f1cb5a8e14c202750

thank you guys for the insight, here the updated version using volley 1.2.1 (latest) https://gist.github.com/4sskick/d1318379500747564d8f1c8d6af1f796 in case still you guys still has old project which need to maintain but don't want to refactor to OkHttp or another request library
