Automatic cookie handling with OkHttp 3

If you want to use the new OkHttp 3 CookieJar and get rid of the okhttp-urlconnection dependency you can use this PersistentCookieJar.

You only need to create an instance of PersistentCookieJar and then just pass it to the OkHttp builder:

CookieJar cookieJar =
                    new PersistentCookieJar(new SetCookieCache(), new SharedPrefsCookiePersistor(context));

OkHttpClient okHttpClient = new OkHttpClient.Builder()
                    .cookieJar(cookieJar)
                    .build();

Here you have a simple approach to create your own CookieJar. It can be extended as you wish. What I did is to implement a CookieJar and build the OkHttpClient using the OkHttpClient.Builder with this this CookieJar.

public class MyCookieJar implements CookieJar {

    private List<Cookie> cookies;

    @Override
    public void saveFromResponse(HttpUrl url, List<Cookie> cookies) {
        this.cookies =  cookies;
    }

    @Override
    public List<Cookie> loadForRequest(HttpUrl url) {
        if (cookies != null)
            return cookies;
        return new ArrayList<Cookie>();

    } 
}

Here is how you can create the OkHttpClient

OkHttpClient.Builder builder = new OkHttpClient.Builder();
builder.cookieJar(new MyCookieJar());
OkHttpClient client = builder.build();

right now I'm playing with it. try PersistentCookieStore, add gradle dependencies for JavaNetCookieJar:

compile "com.squareup.okhttp3:okhttp-urlconnection:3.0.0-RC1"

and init

    // init cookie manager
    CookieHandler cookieHandler = new CookieManager(
            new PersistentCookieStore(ctx), CookiePolicy.ACCEPT_ALL);
    // init okhttp 3 logger
    HttpLoggingInterceptor logging = new HttpLoggingInterceptor();
    logging.setLevel(HttpLoggingInterceptor.Level.BODY);
    // init OkHttpClient
    OkHttpClient httpClient = new OkHttpClient.Builder()
            .cookieJar(new JavaNetCookieJar(cookieHandler))
            .addInterceptor(logging)
            .build();

`

Adding compile "com.squareup.okhttp3:okhttp-urlconnection:3.8.1" to your build.gradle.

And then adding

 CookieManager cookieManager = new CookieManager();
 cookieManager.setCookiePolicy(CookiePolicy.ACCEPT_ALL);

 OkHttpClient defaultHttpClient = new OkHttpClient.Builder()
                                 .cookieJar(new JavaNetCookieJar(cookieManager))
                                 .build()

helped me without adding any third-party dependency except the one from OkHttp.
