How to set timeout in Retrofit library?

Question

I am using Retrofit library in my app, and I'd like to set a timeout of 60 seconds. Does Retrofit have some way to do this?

I set Retrofit this way:

RestAdapter restAdapter = new RestAdapter.Builder()
    .setServer(BuildConfig.BASE_URL)
    .setConverter(new GsonConverter(gson))
    .build();

How can I set the timeout?

Answer 1

You can set timeouts on the underlying HTTP client. If you don't specify a client, Retrofit will create one with default connect and read timeouts. To set your own timeouts, you need to configure your own client and supply it to the RestAdapter.Builder.

An option is to use the OkHttp client, also from Square.

1. Add the library dependency

In the build.gradle, include this line:

compile 'com.squareup.okhttp:okhttp:x.x.x'

Where x.x.x is the desired library version.

2. Set the client

For example, if you want to set a timeout of 60 seconds, do this way for Retrofit before version 2 and Okhttp before version 3 (FOR THE NEWER VERSIONS, SEE THE EDITS):

public RestAdapter providesRestAdapter(Gson gson) {
    final OkHttpClient okHttpClient = new OkHttpClient();
    okHttpClient.setReadTimeout(60, TimeUnit.SECONDS);
    okHttpClient.setConnectTimeout(60, TimeUnit.SECONDS);

    return new RestAdapter.Builder()
        .setEndpoint(BuildConfig.BASE_URL)
        .setConverter(new GsonConverter(gson))
        .setClient(new OkClient(okHttpClient))
        .build();
}

EDIT 1

For okhttp versions since 3.x.x, you have to set the dependency this way:

compile 'com.squareup.okhttp3:okhttp:x.x.x'

And set the client using the builder pattern:

final OkHttpClient okHttpClient = new OkHttpClient.Builder()
        .readTimeout(60, TimeUnit.SECONDS)
        .connectTimeout(60, TimeUnit.SECONDS)
        .build();

EDIT 2

Retrofit versions since 2.x.x also uses the builder pattern, so change the return block above to this:

return new Retrofit.Builder()
    .baseUrl(BuildConfig.BASE_URL)
    .addConverterFactory(GsonConverterFactory.create())
    .client(okHttpClient)
    .build();

If using a code like my providesRestAdapter method, then change the method return type to Retrofit.

ps: If your minSdkVersion is greater than 8, you can use TimeUnit.MINUTES:

okHttpClient.setReadTimeout(1, TimeUnit.MINUTES);
okHttpClient.setConnectTimeout(1, TimeUnit.MINUTES);
