Error unfortunately Stormy has stopped working

I followed all the instructions in the videos however when I try to run the app it crashes and says unfortunately stormy has stooped working not sure what I did wrong. Here is my code

MainActivity

package kharlmccatty.com.stormy;

import android.support.v7.app.ActionBarActivity; import android.os.Bundle; import android.util.Log; import android.view.Menu; import android.view.MenuItem;

import com.squareup.okhttp.Call; import com.squareup.okhttp.Callback; import com.squareup.okhttp.OkHttpClient; import com.squareup.okhttp.Request; import com.squareup.okhttp.Response;

import java.io.IOException;

public class MainActivity extends ActionBarActivity {

public static final String TAG = MainActivity.class.getSimpleName();
@Override
protected void onCreate(Bundle savedInstanceState) {
    String apiKey = "219970594bd1ef4c15dd623ae9828e93";
    double latitude = 37.8267;
    double longitude = -122.423;
    String forecastUrl = "https://api.forecast.io/forecast/" + apiKey +
            "/" + latitude + "," + longitude;

    OkHttpClient client = new OkHttpClient();
    Request request = new Request.Builder()
            .url(forecastUrl)
            .build();
    Call call = client.newCall(request);
    call.enqueue(new Callback() {
        @Override
        public void onFailure(Request request, IOException e) {

        }

        @Override
        public void onResponse(Response response) throws IOException {
            try {
                if(response.isSuccessful()){
                    Log.v(TAG, response.body().string());
                }
            } catch (IOException e) {
                Log.e(TAG, "Exception caught:", e);
            }

        }
    });

}

}

Have a look in the logs for pointers as to which bit of code is causing the problem.

(I remember in this course there were times when the app was deliberately broken and then fixed to explain some concepts, so watch out for those too.)

Make sure you have this in your manifests/AndroidManifest.xml file:

<uses-permission android:name="android.permission.INTERNET" />

Im in the section of the video where it is suppose to run and I do have that kline of code.In the log cat it gives me this error android.app.SuperNotCalledException: Activity {kharlmccatty.com.stormy/kharlmccatty.com.stormy.MainActivity} did not call through to super.onCreate()

Not sure what it means

I figured out the problem I forget my super.onCreate method in the onCreate method. I think I deleted it by accident. Thanks for your help though.
