Retrofit: How to wait for response

I have AsyncTask and the doInBackground method inside which, I sending POST request using Retrofit. My code looks like:

    //method of AsyncTask
    protected Boolean doInBackground(Void... params) {
        Retrofit restAdapter = new Retrofit.Builder()
                .baseUrl(Constants.ROOT_API_URL)
                .addConverterFactory(GsonConverterFactory.create())
                .build();
        IConstructSecureAPI service = restAdapter.create(IConstructSecureAPI.class);
        //request
        Call<JsonElement> result = service.getToken("TestUser", "pass", "password");
        result.enqueue(new Callback<JsonElement>() {
            @Override
            public void onResponse(Call<JsonElement> call, Response<JsonElement> response) {

            }

            @Override
            public void onFailure(Call<JsonElement> call, Throwable t) {

            }
        });

        return true;
    }

The problem is: Retrofit sending request asynchronously and while it, the doInBackground method returning the value. So I need to send a request in the same thread with all executions in the sequence. One by one. And returning from doInBackground occurs after the request finished. How can I send a request in the same thread using Retrofit?

Answer

The Call class has an execute() method that will make your call synchronously.

enqueue() is explicitly for making an asychronous call.
