Android Build a Weather App (2015) Concurrency and Error Handling Executing an Asynchronous Call

concurrency and Error Handling

Next, execute the call by calling the enqueue() method. This method requires a Callback as the parameter. Copy and paste the following code as the Callback:

new Callback() { @Override public void onFailure(Request request, IOException e) { }

@Override
public void onResponse(Response response) throws IOException { }

}

my answer should be correct pliz check it out.

MovieActivity.java
import android.app.Activity;
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 { }
}
                   }

You need to close off the enqueue call and add another brace to end the class definition:

//...

call.enqueue(new Callback() {
            @Override
            public void onFailure(Request request, IOException e) { }

            @Override
            public void onResponse(Response response) throws IOException { }
        });
    }
}

thank you sir sorry for a rather belated thank you message.

sorry im still failing to understand this..please explain if its not too much to ask

import android.app.Activity; 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 { }
    });
}

}

You should be fixed in NO TIME!
