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();

As of OkHttp3 you can do this through the Builder like so

client = new OkHttpClient.Builder()
    .connectTimeout(10, TimeUnit.SECONDS)
    .writeTimeout(10, TimeUnit.SECONDS)
    .readTimeout(30, TimeUnit.SECONDS)
    .build();

You can also view the recipe here .

For older versions, you simply have to do this

OkHttpClient client = new OkHttpClient();
client.setConnectTimeout(15, TimeUnit.SECONDS); // connect timeout
client.setReadTimeout(15, TimeUnit.SECONDS);    // socket timeout

Request request = new Request.Builder().url(url).build();
Response response = client.newCall(request).execute();

Be aware that value set in setReadTimeout is the one used in setSoTimeout on the Socket internally in the OkHttp Connection class.

Not setting any timeout on the OkHttpClient is the equivalent of setting a value of 0 on setConnectTimeout or setReadTimeout and will result in no timeout at all. Description can be found here .

As mentioned by @marceloquinta in the comments setWriteTimeout can also be set.

As of version 2.5.0 read / write / connect timeout values are set to 10 seconds by default as mentioned by @ChristerNordvik. This can be seen here .

For okhttp3 this has changed a bit.

Now you set up the times using the builder, and not setters, like this:

OkHttpClient client = new OkHttpClient.Builder()
        .connectTimeout(10, TimeUnit.SECONDS)
        .writeTimeout(10, TimeUnit.SECONDS)
        .readTimeout(30, TimeUnit.SECONDS)
        .build();

More info can be found in their wiki: https://github.com/square/okhttp/blob/b3dcb9b1871325248fba917458658628c44ce8a3/docs/recipes.md#timeouts-kt-java

For Retrofit retrofit:2.0.0-beta4 the code goes as follows:

OkHttpClient client = new OkHttpClient.Builder()
    .addInterceptor(logging)
    .connectTimeout(30, TimeUnit.SECONDS)
    .readTimeout(30, TimeUnit.SECONDS)
    .writeTimeout(30, TimeUnit.SECONDS)
    .build();

Retrofit retrofit = new Retrofit.Builder()
    .baseUrl("http://api.yourapp.com/")
    .addConverterFactory(GsonConverterFactory.create())
    .client(client)
    .build();

For Retrofit 2.0.0-beta1 or beta2 , the code goes as follows:

OkHttpClient client = new OkHttpClient();

client.setConnectTimeout(30, TimeUnit.SECONDS);
client.setReadTimeout(30, TimeUnit.SECONDS);
client.setWriteTimeout(30, TimeUnit.SECONDS);

Retrofit retrofit = new Retrofit.Builder()
    .baseUrl("http://api.yourapp.com/")
    .addConverterFactory(GsonConverterFactory.create())
    .client(client)
    .build();

Adding in gradle file and sync project :

compile 'com.squareup.okhttp3:okhttp:3.2.0'
compile 'com.google.code.gson:gson:2.6.2'

Adding in Java class:

import okhttp3.OkHttpClient;
import okhttp3.OkHttpClient.Builder;


Builder b = new Builder();
b.readTimeout(200, TimeUnit.MILLISECONDS);
b.writeTimeout(600, TimeUnit.MILLISECONDS);
// set other properties

OkHttpClient client = b.build();

OkHttp Version: 3.11.0 or higher

From okhttp source code:

/**
 * Sets the default connect timeout for new connections. A value of 0 means no timeout,
 * otherwise values must be between 1 and {@link Integer#MAX_VALUE} when converted to
 * milliseconds.
 *
 * <p>The connectTimeout is applied when connecting a TCP socket to the target host.
 * The default value is 10 seconds.
 */
public Builder connectTimeout(long timeout, TimeUnit unit) {
    connectTimeout = checkDuration("timeout", timeout, unit);
    return this;
}

unit can be any value of below

TimeUnit.NANOSECONDS
TimeUnit.MICROSECONDS
TimeUnit.MILLISECONDS
TimeUnit.SECONDS
TimeUnit.MINUTES
TimeUnit.HOURS
TimeUnit.DAYS

example code

OkHttpClient client = new OkHttpClient.Builder()
    .connectTimeout(5000, TimeUnit.MILLISECONDS)/*timeout: 5 seconds*/
    .build();

String url = "https://www.google.com";
Request request = new Request.Builder()
    .url(url)
    .build();

try {
    Response response = client.newCall(request).execute();
} catch (IOException e) {
    e.printStackTrace();
}

Updated

I have add new API to OkHttp from version 3.12.0 , you can set timeout like this:

OkHttpClient client = new OkHttpClient.Builder()
    .connectTimeout(Duration.ofSeconds(5)) // timeout: 5 seconds
    .build();

NOTE: This requires API 26+ so if you support older versions of Android, continue to use (5, TimeUnit.SECONDS) .

It's changed now. Replace .Builder() with .newBuilder()

As of okhttp:3.9.0 the code goes as follows:

OkHttpClient okHttpClient = new OkHttpClient()
    .newBuilder()
    .connectTimeout(10,TimeUnit.SECONDS)
    .writeTimeout(10,TimeUnit.SECONDS)
    .readTimeout(30,TimeUnit.SECONDS)
    .build();

Like so:

//New Request
HttpLoggingInterceptor logging = new HttpLoggingInterceptor();
logging.setLevel(HttpLoggingInterceptor.Level.BASIC);
final OkHttpClient client = new OkHttpClient.Builder()
    .addInterceptor(logging)
    .connectTimeout(30, TimeUnit.SECONDS)
    .readTimeout(30, TimeUnit.SECONDS)
    .writeTimeout(30, TimeUnit.SECONDS)
    .build();

This worked for me:

OkHttpClient client = new OkHttpClient.Builder()
    .connectTimeout(10, TimeUnit.SECONDS)
    .readTimeout(10, TimeUnit.SECONDS)
    .writeTimeout(10, TimeUnit.SECONDS)
    .retryOnConnectionFailure(false) <-- not necessary but useful!
    .build();

If you want to customize the configuration then use the below methodology of creating OKhttpclient first and then add builder on top of it.

private final OkHttpClient client = new OkHttpClient();

// Copy to customize OkHttp for this request.
OkHttpClient client1 = client.newBuilder()
    .readTimeout(500, TimeUnit.MILLISECONDS)
    .build();
try (Response response = client1.newCall(request).execute()) {
    System.out.println("Response 1 succeeded: " + response);
} catch (IOException e) {
    System.out.println("Response 1 failed: " + e);
}

您可以设置调用超时以涵盖从解析 DNS、连接、写入请求正文、服务器处理和读取响应正文的整个周期。

val client = OkHttpClient().newBuilder().callTimeout(CALL_TIMEOUT_IN_MINUTES, TimeUnit.MINUTES).build()
