Retrofit 2: Catch connection timeout exception

I have the following setup:

final OkHttpClient okHttpClient = new OkHttpClient();
okHttpClient.setReadTimeout(5, TimeUnit.SECONDS);
okHttpClient.setConnectTimeout(5, TimeUnit.SECONDS);

RestAdapter.Builder builder = new RestAdapter.Builder()
        .setEndpoint(ROOT)
        .setClient(new OkClient(okHttpClient))
        .setLogLevel(RestAdapter.LogLevel.FULL);

I am trying to handle the situation in which my server is down and the user gets a connection timeout exception, this is my logging:

java.net.SocketTimeoutException: failed to connect to /192.168.0.53 (port 3000) after 5000ms

Full logging: http://pastebin.com/gscCGb7x

Is there a way to route this into the retrofit failure method so I can handle it over there?

Thanks in advance!


For Retrofit 2

Define a listener in your web service instance:

public interface OnConnectionTimeoutListener {
    void onConnectionTimeout();
}

Add an interceptor to your web service:

public WebServiceClient() {
    OkHttpClient client = new OkHttpClient();
    client.setConnectTimeout(10, TimeUnit.SECONDS);
    client.setReadTimeout(30, TimeUnit.SECONDS);
    client.interceptors().add(new Interceptor() {
        @Override
        public Response intercept(Chain chain) throws IOException {
            return onOnIntercept(chain);
        }
    });
    Retrofit retrofit = new Retrofit.Builder()
            .baseUrl(BASE_URL)
            .addConverterFactory(GsonConverterFactory.create())
            .client(client)
            .build();
    webService = retrofit.create(WebService.class);
}

Enclose your intercep code with try-catch block and notify listener when exception happens:

private Response onOnIntercept(Chain chain) throws IOException {
    try {
        Response response = chain.proceed(chain.request());
        String content = UtilityMethods.convertResponseToString(response);
        Log.d(TAG, lastCalledMethodName + " - " + content);
        return response.newBuilder().body(ResponseBody.create(response.body().contentType(), content)).build();
    }
    catch (SocketTimeoutException exception) {
        exception.printStackTrace();
        if(listener != null)
            listener.onConnectionTimeout();
    }

    return chain.proceed(chain.request());
}

@Override
public void onFailure(Call call, Throwable t) {
    if(t instanceof SocketTimeoutException){
        message = "Socket Time out. Please try again.";
    }
}
