Android Build a Weather App (2015) Networking Making an HTTP GET Request with OkHttp

Is there any way that I can send the data from OKHTTP thread to main thread? So I don't have to call runOnUIThread()?

I guess enqueue() method will start a new thread to handle everything with http request. And I'm wondering is there any way that I can send the data back to main thread so I can update UI or change anything in UI thread directly without using runOnUIThread() method? Seems like I don't have the reference to the thread that handles http...

I'm trying to write the code in the following way:

mJSONData = getJsonData(latitude, longitude);

mWeather = getWeather(mJSONData);

updateDispay(mWeather);

you have two options, inside your call back you can do

  MyActivity.this.runOnUiThread(new Runnable() {
         @Override
        public void run() {
           //Handle UI here                                  
        }
     });

or you can do it with a handler

have an insatance var private Handler handler = new Handler(Looper.getMainLooper());

then in your callback

handler.post(new Runnable() {
        @Override
        public void run() {
            Toast.makeText(getApplicationContext(), "email and Password were not correct", Toast.LENGTH_SHORT).show();
        }
    });
