Ribbit crashes when "edit friends" is selected

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);

to

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:

<ListView
        android:id="@android:id/list"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_alignParentLeft="true"
        android:layout_alignParentTop="true" >
    </ListView>

Also having this issue

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() {
    }

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