Retrofit 1.9 with OkHttp 2.2 and interceptors

Question

I thought that these recent versions were supposed to be compatible. There is this tweet; https://twitter.com/JakeWharton/status/553066921675857922 and the changelog of Retrofit 1.9 mentions it too.

However when I try this:

        OkHttpClient httpClient = new OkHttpClient();
        httpClient.interceptors().add(new TokenExpiredInterceptor());

        mRestAdapter = new RestAdapter.Builder()
                .setEndpoint(API_ENDPOINT)
                .setClient(httpClient)
                .setLogLevel(BuildConfig.DEBUG ?
                        RestAdapter.LogLevel.FULL :
                        RestAdapter.LogLevel.NONE)
                .setRequestInterceptor(new AuthorizationInterceptor())
                .build();

It still doesn't work. The setClient method complains about an incompatible Client object;

Error:(29, 21) error: no suitable method found for setClient(OkHttpClient)
method Builder.setClient(Client) is not applicable
(argument mismatch; OkHttpClient cannot be converted to Client)
method Builder.setClient(Provider) is not applicable
(argument mismatch; OkHttpClient cannot be converted to Provider)

What am I missing? I also see OkHttpClient does not implement the Client interface.

I am using this approach for now; https://medium.com/@nullthemall/execute-retrofit-requests-directly-on-okhttp-2-2-7e919d87b64e

Did I misinterpret the changelog? Maye Retrofit 1.9 can uses OkHttpClient 2.2 when it's in the classpath but the interface isn't adapted yet?

Answer 1

You are passing OkHttpClient to the RestAdapter.Builder which accepts Client implementations. OkHttpClient, solely, is not related to Retrofit if not used in Client implementations.

You should pass OkHttpClient to OkClient instance that implements Client

.setClient(new OkClient(httpClient))

OkHttpClient httpClient = new OkHttpClient();
httpClient.interceptors().add(new TokenExpiredInterceptor());

mRestAdapter = new RestAdapter.Builder()
        .setEndpoint(API_ENDPOINT)
        .setClient(new OkClient(httpClient))
        .setLogLevel(BuildConfig.DEBUG ?
                RestAdapter.LogLevel.FULL :
                RestAdapter.LogLevel.NONE)
        .setRequestInterceptor(new AuthorizationInterceptor())
        .build();
