OkHttpClient "open" method missing in v2.0

Question

If you are upgrading from OkHttp library from 1.x to 2.x, glaringly the OkHttpClient method "open" is missing. The below code will NOT compile.

        OkHttpClient client = new OkHttpClient();
        HttpURLConnection conn = client.open(url);

Answer 1

As per the official change log:

URLConnection support has moved to the okhttp-urlconnection module. If you're upgrading from 1.x, this change will impact you. You will need to add the okhttp-urlconnection module to your project and use the OkUrlFactory to create new instances of HttpURLConnection:

// OkHttp 1.x:
HttpURLConnection connection = client.open(url);

// OkHttp 2.x:
HttpURLConnection connection = new OkUrlFactory(client).open(url);

Just remember to add the dependency as below to the Gradle file.

compile 'com.squareup.okhttp:okhttp-urlconnection:2.5.0'
