OkHttp: The Underlying Network Library

Beginning with Mobile SDK 4.2, the Android REST request system uses OkHttp (v3.2.0), an open-source external library from Square Open Source, as its underlying architecture. This library replaces the Google Volley library from past releases. As a result, Mobile SDK no longer defines the WrappedRestRequest class.

Example

The following examples show how to perform some common network operations with OkHttpClient.

Common Imports

1import okhttp3.Headers;
2import okhttp3.HttpUrl;
3import okhttp3.OkHttpClient;
4import okhttp3.Call;
5import okhttp3.Dispatcher;
6import okhttp3.Request;
7import okhttp3.RequestBody;
8import okhttp3.Response;

Obtain the Current OkHttp Client Handle

To get the handle of the OkHttpClient that the current RestClient instance is using:

Kotlin

1var okClient = restClient.getOkHttpClient()

Java

1OkHttpClient okClient = restClient.getOkHttpClient();

Obtain the OkHttp Dispatcher

Kotlin

1var dispatcher = restClient.getOkHttpClient().dispatcher()

Java

1Dispatcher dispatcher = restClient.getOkHttpClient().dispatcher();

Cancel All Pending Calls

Kotlin

1var dispatcher = restClient.getOkHttpClient().dispatcher()
2dispatcher.cancelAll()

Java

1Dispatcher dispatcher = restClient.getOkHttpClient().dispatcher();
2                              dispatcher.cancelAll();

Store the OkHttp Handle to a REST Request

Kotlin

1var call = restClient.sendAsync(restRequest, callback)

Java

1Call call = restClient.sendAsync(restRequest, callback);

Cancel a Specific REST Request Using a Stored Handle

Kotlin

1var call = restClient.sendAsync(restRequest, callback)

Java

1Call call = restClient.sendAsync(restRequest, callback);
2                              ...
3                              call.cancel();
