The LogCat refers to this line of code01-15 22:13:08.277: ERROR/AndroidRuntime(28747): at com.mohit.geo2do.adapters.TasksAdapter.bindView(TasksAdapter.java:60). Here is my task adapter's bindView method:

@Override
public void bindView(View view, Context context, Cursor cursor) {
    CheckBox checkbox = (CheckBox)view.findViewById(R.id.completed);
    TextView due_date = (TextView)view.findViewById(R.id.due_date);

    String title = cursor.getString(cursor.getColumnIndex(Tasks.TITLE));
    boolean completed = Util.intToBool(cursor.getInt(cursor.getColumnIndex(Tasks.COMPLETED)));

    SimpleDateFormat format = new SimpleDateFormat("EEEEEE, MMM dd yyyy hh:mm aa");
    long unixTime = Calendar.getInstance().getTimeInMillis();
    if (cursor.getLong(cursor.getColumnIndex(Tasks.DUE_DATE)) > 0) {
        Log.v("TasksAdapter", "Unix time is " + unixTime);
        unixTime = cursor.getLong(cursor.getColumnIndex(Tasks.DUE_DATE));
        Calendar due = Util.timestampToDate(unixTime);

        due_date.setText(format.format(due.getTime()));
    }
    checkbox.setText(title);
    checkbox.setChecked(completed);
    due_date.setText("No Deadline");
}

I have verified 100% that the column does exist. What could be the problem?

UPDATE:
The cursor is from a bindView method, so I have not created the query for the cursor myself. I recreated the database and now I get this error:

I have verified that the column index is -1:

01-16 09:46:39.434: VERBOSE/TasksAdapter(32563): The index is -1

And that the due_date column exists:

Ensure that the query that generated your Cursor includes the field which Tasks.DUE_DATE refers to. If it does not, getColumnIndex will return -1. You can also use getColumnIndexOrThrow, which allows you to catch an IllegalArgumentException.
