Code Challenge: Trying Code and Catching Exceptions

Third task: Log the exception using the Log.e() method that takes an exception variable as its 3rd parameter. Use the String "CodeChallenge" for the 1st parameter and any String for the 2nd parameter.

I have no idea what I'm doing wrong here.

This is my code: 

package com.example;

import android.os.Bundle;
import android.view.View;
import java.net.MalformedURLException;
import android.util.Log;

public class MainListActivity extends ListActivity {

public static final String URL = "teamtreehouse.com";
public static final String CodeChallenge = MainListActivity.class.getSimpleName();  

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main_list);
  try{
    URL treehouseUrl = new URL(URL);
  }
  catch(MalformedURLException e){
    Log.e(CodeChallenge, randomString, e);
  }


}

}

Never mind, the next code challenge had the answer.

Log.e("CodeChallenge", "MalformedURLException caught!", e);

It might be helpful to say in the description for the third task that CodeChallenge needs the quotes around it.

Agree, had all my code right except for those quotes. Glad I wasn't the only one or I might have been stuck on that one a while.

Hi Jasper van Riet,

Glad you were able to figure it out! Sorry for the confusion. I'll pass this feedback along to Ben Jakuben, our Android teacher.

Oh got it, if you follow the instructions it says "CodeChallenge" and for any string you put " " .

The answer is

Log.e("CodeChallenge", "MalformedURLException caught!", e);

And it fits into the rest of the code like this 

package com.example;

import android.os.Bundle;
import android.view.View;
import java.net.MalformedURLException;
import android.util.Log;



public class MainListActivity extends ListActivity {

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

        // Add Task 2 code here
        try {
            URL treehouseUrl = new URL(URL);
        } 
        catch(MalformedURLException e) {
            Log.e("CodeChallenge", "MalformedURLException caught!", e);
        }

    }
  public static final String URL ="teamtreehouse.com";
}
