GET 请求 OkHTTP 抛出异常

Question

I have GET request OkHTTP in android studio.

public class ReceiveMessage {
OkHttpClient client = new OkHttpClient().newBuilder()
        .build();

public void getReceiveRequest(String user) {
    Request request = new Request.Builder()
            .url("localhost:8080/tuk_tuk/4353453465")
            .method("GET", null)
            .build();

    client.newCall(request).enqueue(new Callback() {
        @Override
        public void onFailure(Call call, IOException e) {
            call.cancel();
        }

        @Override
        public void onResponse(Call call, Response response) throws IOException {
            assert response.body() != null;
            Log.d("TAG",response.body().string());
        }
    });

}

}

I create object ReceiveMessege. Then I call method getReceiveRequest in MainActivity. But i get Exception:

Uncorrect url format!
