Ribbit crashes when "edit friends" is selected

When I select "Edit friends" from the menu, the app crashes. LogCat says "your content must have ListView whose id attribute is 'android.R.id.list'". I've replaced each of my .java files with the project files posted with the video - none resolve the error. Anyone else experiencing this issue?

In layout/activity_edit_friends.xml, try changing android:id property to android:id="@android:id/list"

I am also having the smae error. I changed the array adapter rrayAdapter<String> adapter = new ArrayAdapter<String>(EditFriendsActivity.this, android.R.layout.simple_list_item_checked, usernames);


rrayAdapter<String> adapter = new ArrayAdapter<String>(EditFriendsActivity.this, android.R.id.list, usernames);

no change in outcome.

Help please

What I did to fix the solution was to add a ListView to activity_edit_friends.xml. I just copied the same one from the fragment_friends.xml and then everything worked properly!

Here is the code i used:

        android:layout_alignParentTop="true" >

Comparing my file to the files in the solution, it appears I had extra code that was auto generated.

In EditFrindsActivity, commented out the following blocks and it stopped crashing.

In onCreate: /* if (savedInstanceState == null) { getFragmentManager().beginTransaction() .add(R.id.container, new PlaceholderFragment()).commit(); } */

AND at the bottom of the file: /** * A placeholder fragment containing a simple view. */

public static class PlaceholderFragment extends Fragment {

    public PlaceholderFragment() {

    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
        View rootView = inflater.inflate(R.layout.activity_edit_friends,
                container, false);
        return rootView;
