Let's add the same Intent flags from the video to flag this new activity as a new task and to clear the current task.

Hi guys, i need help here. Thanks in advance!

import android.app.Activity;
import android.content.Intent;

public class CodeChallengeActivity extends Activity {

    // Some code has been omitted

    public void addComment() {
      Intent intent = new Intent(this, CommentActivity.class);

The variable was misspelled.

Change intnet to intent and it should work.

Hope this helps!
