PersistentCookieJar for OkHttp 3

A persistent CookieJar implementation for OkHttp 3 based on SharedPreferences.

If you're looking for a OkHttp 2/HTTPUrlConnection persistent CookieStore it can be found at this Gist.

Download

Step 1. Add the JitPack repository in your root build.gradle at the end of repositories:

allprojects {
    repositories {
        ...
        maven { url "https://jitpack.io" }
    }
}

Step 2. Add the dependency

dependencies {
    compile 'com.github.franmontiel:PersistentCookieJar:v1.0.1'
}

Usage

Create an instance of PersistentCookieJar passing a CookieCache and a CookiePersistor:

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

Then just add the CookieJar when building your OkHttp client:

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

Features

This is a really simple library but here are some of the things that it provides:

  • Possibility to clear the jar: PersistentCookieJar implements ClearableCookieJar interface that declares a clear() method for removing all cookies from the jar.

  • Possibility to clear session cookies: PersistentCookieJar implements ClearableCookieJar interface that declares a clearSession() method for removing session cookies from the jar.

  • Decoupled and extensible: CookieCache and CookiePersistor are interfaces so you can provide your own implementation for each one.

    • CookieCache represents an in-memory cookie storage. SetCookieCache is the provided implementation that uses a Set to store the Cookies.
    • CookiePersistor represents a persistent storage. SharedPrefsCookiePersistor is the provided implementation that uses a SharedPreferences to persist the Cookies.
  • Thread-safe: PersistentCookieJar public methods are synchronized so there is no need to worry about threading if you need to implement a CookieCache or a CookiePersistor.

ProGuard

The following configuration is only needed for version 0.9.2 and below:

-dontwarn com.franmontiel.persistentcookiejar.**
-keep class com.franmontiel.persistentcookiejar.**

-keepclassmembers class * implements java.io.Serializable {  
    static final long serialVersionUID;  
    private static final java.io.ObjectStreamField[] serialPersistentFields;  
    !static !transient <fields>;  
    private void writeObject(java.io.ObjectOutputStream);  
    private void readObject(java.io.ObjectInputStream);  
    java.lang.Object writeReplace();  
    java.lang.Object readResolve();  
}
