to create and build a Request. Declare a new Request variable, and then set it by chaining a few methods together.

import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;

public class MovieActivity extends Activity {
   String apiUrl; 
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_movie);
      OkHttpClient a = new OkHttpClient();
      Request request=new Request.Builder()
                                  .url(apiUrl)
                                  .build();

        // Get some movie information!
        String apiUrl = "http://api.rottentomatoes.com/api/public/v1.0/movies.json?apikey=xyz&q=hobbit";
    }
}
