Cannot Resolve Symbol OkHttpClient

So basically my code kept crashing so I downloaded his code and replaced MainActivity.java with Ben's code. Now it doesn't recognize anything from OkHttpClient like it's imports, Objects, and classes. This is bad, and I still get that error.

** package com.tsm.stormy; //test import android.content.Context; import android.net.ConnectivityManager; import android.net.NetworkInfo; import android.os.Bundle; import android.support.v7.app.ActionBarActivity; import android.util.Log; import android.widget.Toast;

            "/" + latitude + "," + longitude;

    if (isNetworkAvailable()) {
