Android unable to write datetime to sqllite database

I'm using the Google Tasks API in my app. One of the fields in my app "due date" requires a DateTime object. Im using the Android datepicker dailog and an EditText view to capture the due date and then converting the user input into the datetime format. When I try to write to my SQLite database I get the following exception.

Error inserting due=2015-06-14T15:58:38.572-04:00 title=Test app _id=TaskId0.07429873487580996 status=needsAction notes=Test write
    android.database.sqlite.SQLiteException: table tasks has no column named due (code 1): , while compiling: INSERT INTO tasks(due,title,_id,status,notes) VALUES (?,?,?,?,?)

which is confusing because I do define a column named "due". Further up in the logs there is another exception.

06-14 15:58:38.607  15395-15395/com.github.idclark.forgetmenot E/EDITFRAGMENT﹕ null
    java.text.ParseException: Unparseable date: "06/14/15" (at offset 8)
            at java.text.DateFormat.parse(DateFormat.java:579)
            at com.github.idclark.forgetmenot.EditFragment.getTaskDueDate(EditFragment.java:64)

The Schema is defined as

public static final class TaskEntry implements BaseColumns {

        public static final String TABLE_NAME = "tasks";
        public static final String COLUMN_TASK_ID = "_id";
        public static final String COLUMN_TASK_TITLE = "title";
        public static final String COLUMN_TASK_UPDATED = "updated";
        public static final String COLUMN_TASK_SELFLINK = "selfLink";
        public static final String COLUMN_TASK_PARENT = "parent";
        public static final String COLUMN_TASK_POSITION = "position";
        public static final String COLUMN_TASK_NOTES = "notes";
        public static final String COLUMN_TASK_STATUS = "status";
        public static final String COLUMN_TASK_DUE = "due";
        public static final String COLUMN_TASK_COMPLETED = "completed";
        public static final String COLUMN_TASK_DELETED = "deleted";
        public static final String COLUMN_TASK_HIDDEN = "hidden";

so the "due" column does exist. And the table is created by

@Override
    public void onCreate(SQLiteDatabase db) {

        //status must be either needsAction or completed

        final String CREATE_TASK_TABLE =
                "CREATE TABLE " + TaskEntry.TABLE_NAME + " (" +
                        TaskEntry._ID + " INTEGER PRIMARY KEY," +
                        TaskEntry.COLUMN_TASK_ID + "TEXT NOT NULL, " +
                        TaskEntry.COLUMN_TASK_TITLE + "TEXT NOT NULL, " +
                        TaskEntry.COLUMN_TASK_COMPLETED + "TEXT, " +
                        TaskEntry.COLUMN_TASK_NOTES + "TEXT, " +
                        TaskEntry.COLUMN_TASK_STATUS + "TEXT NOT NULL, " +
                        TaskEntry.COLUMN_TASK_DUE + "DATETIME, " +
                        TaskEntry.COLUMN_TASK_UPDATED + "DATETIME, " +
                        TaskEntry.COLUMN_TASK_PARENT + "TEXT, " +
                        TaskEntry.COLUMN_TASK_DELETED + "BOOLEAN, " +
                        TaskEntry.COLUMN_TASK_SELFLINK + "TEXT, " +
                        TaskEntry.COLUMN_TASK_POSITION + "TEXT, " +
                        TaskEntry.COLUMN_TASK_HIDDEN + "TEXT" + ")";

        db.execSQL(CREATE_TASK_TABLE);
    }

The due date conversion takes place in this method.

public DateTime getTaskDueDate() {
        mDueDate = (EditText) getActivity().findViewById(R.id.task_due_date);

        Date date = new Date();
        DateTime googleDate = new DateTime(date);
        try {
            SimpleDateFormat sdf = new SimpleDateFormat();
            Date taskDueDate = sdf.parse(mDueDate.getText().toString());
            googleDate = new DateTime(taskDueDate);
        } catch (ParseException ex) {
            Logger.getLogger("EDITFRAGMENT").log(Level.SEVERE, null, ex);
        } finally {

        }
        return googleDate;
    }

The data is then finally written to the database with

public boolean insertRow(Task task) {
        ContentValues values = new ContentValues();
        values.put(TaskContract.TaskEntry.COLUMN_TASK_STATUS, task.getStatus());
        values.put(TaskContract.TaskEntry.COLUMN_TASK_ID,task.getId());
        values.put(TaskContract.TaskEntry.COLUMN_TASK_TITLE,task.getTitle());
        values.put(TaskContract.TaskEntry.COLUMN_TASK_DUE, task.getDue().toString());
        values.put(TaskContract.TaskEntry.COLUMN_TASK_NOTES, task.getNotes());

        SQLiteDatabase db = this.getWritableDatabase();
        boolean createSuccessful = db.insert(TaskContract.TaskEntry.TABLE_NAME, null, values) > 0;
        db.close();
        return createSuccessful;
    }

I'm confused as to why this write fails, and sql claims that there is no "due" column. Even though there is a parse exception, I see a timestamp in the logs as well. Is part of the problem that i'm calling .toString() on the datetime object before writing it to the db? I don't have a lot of sql experience and am genuinely confused as to what to make of these exceptions.
