Android Lollipop网络API和OkHttp

Question

I running into an issue routing network calls using OkHttp. I'm trying to send HTTP requests to a local device (via the device's ip) using an Access Point that has no internet access. Due to some changes in Android 5.0, OkHttp will try to route the request over data instead, which then fails.

In Android 5.0's Network API, I could use the NetworkCapabilities class along with the NetworkRequest.Builder in order to tell the request to only go over Wi-Fi, However, I'm already using OkHttp and I don't want to overhaul my code. Is there anyway to do a similar thing with OkHttp?

Answer 1

I came up with a workaround:

final Network currentNetwork = (Network) network;
newClientBuilder.socketFactory(((Network)network).getSocketFactory())
    .dns(new Dns() {
          @Override
          public List<InetAddress> lookup(String hostname) throws UnknownHostException {
                        return Arrays.asList(currentNetwork.getAllByName(hostname));
                    }
                });

We'd like to eventually include such functionality directly in OkHttp, and you might be the first volunteer/victim to test things out. What you probably want to do is use OkHttp 2.6's new Dns interface to call through to the network of your choice. If that works, either the IP address will cause OkHttp to do the right thing anyway, or you'll also need to replace the SocketFactory .
