An HTTP+SPDY client for Android and Java applications. OkHttp an http & spdy client for android and java applications

Is Retrofit+Okhttp using httpCaching as a default in Android?

I use retrofit and okhttp in one of our applications.

I can't really find a good explanation for the default behaviour of Retrofit.

If Okhttp is on the class path it will be automatically used. But as far as I can see it the default HttpResponseCache is null.

Do I need to explicitly enable caching with Retrofit and Okhttp?

How to implement cookie handling on Android using OkHttp?

Using OkHttp by Square https://github.com/square/okhttp, how can I:

  1. Retrieve a cookie returned from the server
  2. Store the cookie for upcoming requests
  3. Use the stored cookie in subsequent requests
  4. Update the cookie returned by the subsequent request

Ideally the cookie would be stored, resent and updated automatically with every request.

Is it possible to disable following redirects in OkHttp 2.0?

In Android, I'd like to use the new OkHttp 2.0 to request some URLs, but I'd like more control over redirects. I've already found the option to enable or disable following HTTPS → HTTP or HTTP → HTTPS redirects, but I'd like to not follow any redirects, so I can update my GUI as soon as possible, and choose whether to follow them from application logic. I don't see an option to do this. Is it possible, and if so, how can I achieve this?

How to set connection timeout with OkHttp

I am developing app using OkHttp library and my trouble is I cannot find how to set connection timeout and socket timeout.

   OkHttpClient client = new OkHttpClient();

   Request request = new Request.Builder().url(url).build();

   Response response = client.newCall(request).execute();

Retrofit connection failure returns RetrofitError.response as null

Using Retrofit 1.6.0, OkHTTP 2.0.0, and OkHTTP-UrlConnection 2.0.0.

I am doing a POST to a service using Retrofit to a URL that does not exist. The failure callback is called, as expected. However, the RetrofitError parameter does not have a response. I would really like to grab the HTTP status code that was returned by using


but since getResponse() returns null, I can't.

Why is getResponse() null and how can I get the status?


Also, the error I am receiving is UnknownHostException, as expected. Repeat: I am expecting this error. I want to know how to get the HTTP status code or why error.getResponse() returns null.

Edit: Here's some code:

    RestAdapter restAdapter = new RestAdapter.Builder()
    sService = restAdapter.create(ServiceInterface.class);

    void login(@Body JsonObject body, Callback<String> callback);

    public void failure(RetrofitError error) {
        if (error.getResponse() == null) {

            // error.getResponse() is null when I need to get the status code
            // from it.

OkHttp how to log request body

I'm using an interceptor, and I would like to log the body of a request I'm making but I can't see any way of doing this.

Is it possible ?

public class LoggingInterceptor implements Interceptor {
    public Response intercept(Chain chain) throws IOException {
        Request request = chain.request();

        long t1 = System.nanoTime();
        Response response = chain.proceed(request);
        long t2 = System.nanoTime();

        double time = (t2 - t1) / 1e6d;

        if (request.method().equals("GET")) {
            Logs.info(String.format("GET " + F_REQUEST_WITHOUT_BODY + F_RESPONSE_WITH_BODY, request.url(), time, request.headers(), response.code(), response.headers(), response.body().charStream()));
        } else if (request.method().equals("POST")) {
            Logs.info(String.format("POST " + F_REQUEST_WITH_BODY + F_RESPONSE_WITH_BODY, request.url(), time, request.headers(), request.body(), response.code(), response.headers(), response.body().charStream()));
        } else if (request.method().equals("PUT")) {
            Logs.info(String.format("PUT " + F_REQUEST_WITH_BODY + F_RESPONSE_WITH_BODY, request.url(), time, request.headers(), request.body().toString(), response.code(), response.headers(), response.body().charStream()));
        } else if (request.method().equals("DELETE")) {
            Logs.info(String.format("DELETE " + F_REQUEST_WITHOUT_BODY + F_RESPONSE_WITHOUT_BODY, request.url(), time, request.headers(), response.code(), response.headers()));

        return response;

and the result :

POST  [some url] in 88,7ms
    ZoneName: touraine
    Source: Android
    body: retrofit.client.OkClient$1@1df53f05 <-request.body().toString() gives me this, but I would like the content string
    Response: 500
    Date: Tue, 24 Feb 2015 10:14:22 GMT
    body: [some content]

This is a stack trace I get when running an android app I recently inherited. We're not using okhttp as an explicity dependency, and the com.android.okhttp in the trace makes me think the aosp is using okhttp now internally?

How to get response body to retrofit exception?

I am trying to connect to rest service via retrofit in android application. I am getting responses. But when there is some error response from the service, conversion exception occurs and now I want to do some actions based on the response body. But I am getting response body as NULL. But retrofit log has a error message. Why is this happening.

  public void failure(RetrofitError arg0) {
                String response = null;

                TokenError r = (TokenError) arg0
                response = r.getErrorDetails();

                Log.e(TAG, response);
                if (response != null
                        && response.contains("Invalid Token ID"))


Here I am getting r as NULL. I don't know why? Do I need to set something with rest adapter so that the response will be passed to retrofit error object.

How to specify a default user agent for okhttp 2.x requests

I am using okhttp 2.0 in my Android app and didn't find a way to set some common User Agent for all outgoing requests.

I thought I could do something like

OkHttpClient client = new OkHttpClient();

...but there's no such method or similar. Of course I could provide some extension utility method which would wrap a RequestBuilder to attach .header("UserAgent") and then I would use it for building all my requests, but I thought maybe I missed some existing and simpler way?

Using OKHttp, what is the difference between synchronous request in AsyncTask and OKhttp Asynchronous request?

OKHttp supports both synchronous and asynchronous api. If I want to issue an async request, I can:

  1. Use a AsyncTask, and issue OKhttp synchronous api.
  2. Issue a OKhttp asynchronous api.

What is the difference between these 2 options? And which one is better?

Retrofit + RxJava fails to cache responses, suspected response headers

I'm trying to configure cache with Retrofit 1.9.0 and OkHtttp 2.5.0.

Here is how I provide OkHttpClient for my RestAdapter:

public OkHttpClient provideOkHttpClient() {
    OkHttpClient okHttpClient = new OkHttpClient();
    okHttpClient.setConnectTimeout(TIMEOUT_IN_SECONDS, TimeUnit.SECONDS);
    okHttpClient.setReadTimeout(TIMEOUT_IN_SECONDS, TimeUnit.SECONDS);
    okHttpClient.setWriteTimeout(TIMEOUT_IN_SECONDS, TimeUnit.SECONDS);

    File cacheDir = new File(context.getCacheDir(), "http");
    final Cache cache = new Cache(cacheDir, DISK_CACHE_SIZE_IN_BYTES);

    okHttpClient.interceptors().add(new Interceptor() {
        public Response intercept(Chain chain) throws IOException {

            Response response = chain.proceed(request);
            Response finalResponse = response.newBuilder()
                    .header("Cache-Control", String.format("public, max-stale=%d", 604800))

            Log.d("OkHttp", finalResponse.toString());
            Log.d("OkHttp Headers", finalResponse.headers().toString());
            return finalResponse;

    return okHttpClient;

I did not forget to setClient on RestAdapter.Builder. Also made sure, that I'm actually using instance of RestAdapter with this client set.

Even checked if the files are created under "http" folder. They are.

However after I turn of WIFI and reload my screen I end up in OnError callback of Observable endpoint with this message:

retrofit.RetrofitError: failed to connect to / (port 8888) after 10000ms: connect failed: ENETUNREACH (Network is unreachable)

DISCLAIMER: I should probably mention that the final Observable is combined from 5 others, with flatMap and zip on the way.

retrofit + okhttp : Retrieve GZIPInputStream

I have a problem when i activate gzip on WS using retrofit 1.4.1 and okhttp 1.3.0.

RequestInterceptor requestInterceptor = new RequestInterceptor() {

Retrofit 1.9 with OkHttp 2.2 and interceptors

I thought that these recent versions were supposed to be compatible. There is this tweet; https://twitter.com/JakeWharton/status/553066921675857922 and the changelog of Retrofit 1.9 mentions it too.

However when I try this:

        OkHttpClient httpClient = new OkHttpClient();
        httpClient.interceptors().add(new TokenExpiredInterceptor());

        mRestAdapter = new RestAdapter.Builder()
                .setLogLevel(BuildConfig.DEBUG ?
                        RestAdapter.LogLevel.FULL :
                .setRequestInterceptor(new AuthorizationInterceptor())

It still doesn't work. The setClient method complains about an incompatible Client object;

Error:(29, 21) error: no suitable method found for setClient(OkHttpClient)
method Builder.setClient(Client) is not applicable
(argument mismatch; OkHttpClient cannot be converted to Client)
method Builder.setClient(Provider) is not applicable
(argument mismatch; OkHttpClient cannot be converted to Provider)

What am I missing? I also see OkHttpClient does not implement the Client interface.

I am using this approach for now; https://medium.com/@nullthemall/execute-retrofit-requests-directly-on-okhttp-2-2-7e919d87b64e

Did I misinterpret the changelog? Maye Retrofit 1.9 can uses OkHttpClient 2.2 when it's in the classpath but the interface isn't adapted yet?
