Android Build a Weather App (2015) Concurrency and Error Handling Building an Alert Dialog

I'm not sure what I am doing wrong here.

I get a compiler error, but I can't figure out what I am doing wrong

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

public class AlertDialogFragment extends DialogFragment {

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

        // Insert code here!
      AlertDialog.Builder builder = new AlertDialog.Builder(context);
      builder.setTitle("Sorry!");
      builder.setMessage("Ty again!")
        .setPositiveButton("OK", new DialogInterface.setOnClickListener(null) 

        return null;
    }
}
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 { }
        });
    }
}

Hi Bryan,

there were a few errors in your code. First, in the message string you misspelled "Try again". Also, instead of new DialogInterface just pass null. After this statement, you forgot a semicolon and a closing brace. I improved your code by using method chaining, no need to type builder several times.

This code should work for you:

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

public class AlertDialogFragment extends DialogFragment {

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

        // Insert code here!
      AlertDialog.Builder builder = new AlertDialog.Builder(context)
        .setTitle("Sorry!")
        .setMessage("Try again!")
        .setPositiveButton("OK", null);

      AlertDialog dialog = builder.create();

        return dialog;
    }
}

With my best regards,

Philip
