Retrofit 2/OkHttp: Cancel all running requests

Question

I\'m using Retrofit 2-beta2 with OkHttp 2.7.0.

To get the OkHttpClient object from Retrofit I\'m using the Retrofit .client() method and to cancel all it

Answer 1

UPDATE: This is now much easier to achieve in OkHttp 3 by using Dispatcher which has a cancelAll() method. The dispatcher is returned from OkHttpClient.dispatcher().

Old Solution: The only way to do this (that I could find) is to create a subclass of OkHttpClient and use that with Retrofit.

class OkHttpClientExt extends OkHttpClient {
    static final Object TAG_CALL = new Object();

    @Override
    public Call newCall(Request request) {
        Request.Builder requestBuilder = request.newBuilder();
        requestBuilder.tag(TAG_CALL);
        return super.newCall(requestBuilder.build());
    }
}

The following line cancels all requests with tag TAG_CALL. Since the class above sets TAG_CALL on all requests, so all requests are cancelled.

retrofit.client().cancel(OkHttpClientExt.TAG_CALL);
