title: square - okhttp - OkHttpClient cannot be resolved
body: <p>Currently I am working on the <a href="https://teamtreehouse.com/library/build-a-weather-app/networking/making-an-http-get-request-with-okhttp" rel="noreferrer">Stormy Treehouse Android app</a>. I want to use the <a href="https://github.com/square/okhttp" rel="noreferrer">square OkHttpClient</a> but I get an error "cannot resolve symbol okhttp3" when importing the class : <code>import com.squareup.okhttp3.OkHttpClient;</code>. Replacing okhttp3 with okhttp does not fix the error. Thanks for you help.</p>
  
  <h3>MainActivity.java</h3>
  
  <pre><code>package com.trainerworkout.stormy;
  
  import android.support.v7.app.AppCompatActivity;
  import android.os.Bundle;
  
  // cannot resolve symbol 'okhttp3'
  import com.squareup.okhttp3.OkHttpClient;
  
  public class MainActivity extends AppCompatActivity {
  
      @Override
      protected void onCreate(Bundle savedInstanceState) {
          String apiKey = "f9d033c3cdeab16b95cecdeb6721a093";
          double latitude = 45.5124;
          double longitude = -73.5547;
          String forecastUrl = "https://api.forecast.io/forecast/" + apiKey + "/" + latitude + "," + longitude;
          // Cannot resolve symbol
          OkHttpClient client = new OkHttpClient();
  
          super.onCreate(savedInstanceState);
          setContentView(R.layout.activity_main);
      } // onCreate()
  } // MainActivity
