What I have done

Answer 1

The method execute(Request) is undefined for the type OkHttpClient

You are getting this exception because there is no such method ie.execute(Request) for OkHttpClient. Rather it is invoked on Call object which is obtained using OkHttpClient object as follows:

  Call call = client.newCall(request);
  Response response = call.execute();

I think you should be using

Response response = client.newCall(request).execute();

instead of Response response = client.execute(request);

Answer 2

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    new AsyncTask<String, Integer, String> (){

        @Override
        protected String doInBackground(String... params) {
            // TODO Auto-generated method stub
            try {
                client = new OkHttpClient();
                s = post("https://raw.github.com/square/okhttp/master/README.md","");
            } catch (Exception e) {
                // TODO: handle exception
                e.printStackTrace();
            }
            return null;
        }

        @Override
        protected void onPostExecute(String result) {
            super.onPostExecute(result);
            Log.e("ANSWER", "" + s);

        }
    }.execute();

}

Answer 3

I think you should use the new 2.0 RC of okHttp.

To make a POST petition, the best is :

String post(String url, String json) throws IOException {
    RequestBody body = RequestBody.create(JSON, json);
    Request request = new Request.Builder()
        .url(url)
        .post(body)
        .build();
    Response response = client.newCall(request).execute();
    return response.body().string();
}

Answer 4

You only need to replace: This:

Response response = client.execute(request);

By:

Response response = client.newCall(request).execute();

Answer 5

you are missing this line

OkHttpClient client = new OkHttpClient();

Answer 6

@Override
protected String doInBackground(String... ulr) {
    Response response = null;
    OkHttpClient client = new OkHttpClient();
    Request request = new Request.Builder()
    .url(ulr[0])
    .build();

    try {
        response = client.newCall(request).execute();
         return response.body().string();
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
    return null;        
}

use like this!
