Retrieving Messages code challenge objective 1 of 3


I'm having an error with my code and I'm not sure what is the problem. Here's my code:

import android.app.Activity; import android.os.Bundle; import com.parse.ParseQuery; import com.parse.ParseObject; import com.parse.FindCallback;

public class MainActivity extends Activity {

public void onCreate(Bundle savedInstanceState) 

    /* Add code below! */
  ParseQuery<ParseObject> query = new ParseQuery("DoctorWhoEpisodes");



And here's the error I'm receiving:

Note: ./MainActivity.java uses unchecked or unsafe operations. Note: Recompile with -Xlint:unchecked for details.

Thanks in advance

You need to declare the type of data being passed back through the query in the constructor - don't forget that ParseQuery is a generic class that needs to have a specified type. So in this case:

new ParseQuery<ParseObject>("DoctorWhoEpisodes");

Hope this helps!
