How to implement Android Volley with OkHttp 2.0?

Question

This OkHttpStack is no longer supported in OkHttp2.0: https://gist.github.com/JakeWharton/5616899

What is the current pattern to integrate OkHttp 2.0.0 with Volley?

Curiel

There is a comment already on that gist pointing to an OkHttp 2.0 version of HttpStack support. – Loseff

Yes, but the class that ceram1 posted has a customized cache handling. I was looking for the simplest way. And also, I have no idea if that implementation is optimal/standard/correct – Curiel

Answer 1

You must use okhttp-urlconnection module that implements the java.net.HttpURLConnection API, so:

• Download or set a dependency for okhttp-urlconnection

• Rewrite your OkHttpStack to make use of the OkUrlFactory class:

  public class OkHttpStack extends HurlStack {
     private final OkUrlFactory okUrlFactory;
     public OkHttpStack() {
         this(new OkUrlFactory(new OkHttpClient())); 
     }
     public OkHttpStack(OkUrlFactory okUrlFactory) {
         if (okUrlFactory == null) {
             throw new NullPointerException("Client must not be null.");
         }
         this.okUrlFactory = okUrlFactory;
     }
     @Override
     protected HttpURLConnection createConnection(URL url) throws IOException {
         return okUrlFactory.open(url);
     }
  }

I used this solution and added the following gradle dependencies: compile 'com.squareup.okhttp:okhttp:2.0.0' compile 'com.squareup.okhttp:okhttp-urlconnection:2.0.0' compile 'com.squareup.okio:okio:1.0.1' – Curiel

You can use this also

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

/**
 * 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);
    }
}

I think this is more readable than the @fjmontiel answer but besides that is exactly the same, isn't it? – Dyedinthewool

yes!, there are many gist available depending upon the requirement like for ssl gist.github.com/tbruyelle/0729aef4df2c11b21fdf – Clemens

Answer 3

You can also do this now without the dependency on HttpURLConnection:
