I'm developing an app that uses ActionBarSherlock. The app works fine when run on SDK v15(ICS), but crashes with SDK v8 (Froyo)!

Here is the error I'm getting: 

```

Here is the relevant XML in question (line 10 is when the first TextView is declared):

```
<?xml version="1.0" encoding="utf-8"?>

<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:padding="10dp">
    <TextView xmlns:android="http://schemas.android.com/apk/res/android"
        android:id="@+id/title"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:textSize="16dp"
        android:textColor="#000000"
        android:gravity="center_vertical"
        android:paddingLeft="?android:attr/listPreferredItemPaddingLeft"
        android:paddingRight="?android:attr/listPreferredItemPaddingRight"
    />

    <TextView xmlns:android="http://schemas.android.com/apk/res/android"
        android:id="@+id/source_date"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:textSize="10dp"
        android:textColor="#666666"
        android:gravity="center_vertical"
        android:paddingLeft="?android:attr/listPreferredItemPaddingLeft"
        android:paddingRight="?android:attr/listPreferredItemPaddingRight"
    />
</LinearLayout>

```

And here is the relevant my HeadlineAdapter.java code (line 44 is noted with a comment):

```
class HeadlineAdapter extends ArrayAdapter<SyndEntryEnhanced> {
    private int mLayoutResourceID;
    private Context mContext;
    private class HeadlineHolder {
        TextView title;
        TextView source_date;
    }

    public HeadlineAdapter(Context context, int textViewResourceId, ArrayList<SyndEntryEnhanced> list) {
        super(context, textViewResourceId, list);
        this.mContext = context;
        this.mLayoutResourceID = textViewResourceId;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        View row = convertView;
        HeadlineHolder holder = null;

        if (row == null) {
            LayoutInflater infl = (LayoutInflater)((SherlockFragmentActivity)mContext).getLayoutInflater();
            row = infl.inflate(mLayoutResourceID, parent, false);  // LINE 44

            holder = new HeadlineHolder();
            holder.title = (TextView)row.findViewById(R.id.title);
            holder.source_date = (TextView)row.findViewById(R.id.source_date);
            row.setTag(holder);
        } else {
            holder = (HeadlineHolder)row.getTag();
        }

        SyndEntry entry = super.getItem(position).getEntry();
        String title = super.getItem(position).getFeedTitle().trim();
        Date date = entry.getPublishedDate();
        SimpleDateFormat formatter = new SimpleDateFormat("MMM d", Locale.US);

        holder.title.setText(StringEscapeUtils.unescapeHtml(entry.getTitle()));
        if (date == null) {
            holder.source_date.setText(title);
        } else {
            holder.source_date.setText(title + " - " + formatter.format(date));
        }

        return row;
    }
}

```

Any ideas?
