How to set connection timeout with OkHttp

Question

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 OkHttpCl         


        

Answer 1

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.
 *
 * 
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).
