Alert Message

I created a new alertDialog as asked and then tried to return the variable.......Why am I getting an invalid type error?

AlertDialogFragment.java
import android.content.Context;
import android.os.Bundle;

public class AlertDialogFragment extends DialogFragment {

    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState) {
        Context context = getActivity();

        AlertDialog.Builder builder = new AlertDialog.Builder(context);

          builder.setTitle("Sorry!")
                 .setMessage("Try again!")
                 .setPositiveButton("OK", null);
      AlertDialog.Builder build = new AlertDialog.Builder();

        return build;
    }
}
MovieActivity.java
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import java.io.IOException;

public class MovieActivity extends Activity {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_movie);

        // Get some movie information!
        String apiUrl = "http://api.rottentomatoes.com/api/public/v1.0/movies.json?apikey=xyz&q=hobbit";
        OkHttpClient client = new OkHttpClient();
        Request request = new Request.Builder()
                .url(apiUrl)
                .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 { }
        });
    }
}

The method onCreateDialog returns a Dialog, as indicated after the "public" for the method. Right now, you are returning 'build' which is an object of the AlertDialog.Builder class. You can use your builder object to create a Dialog object using builder.create();

I figured it out, I realized after I wrote this that it was a simple mistake........Thank you for the answer though!
