我收到以下错误“E / Sync：java.text.ParseException：Unparseable date：”“（在偏移0处）”

Question

我收到以下错误  “E / Sync：java.text.ParseException：Unparseable date：”“（在偏移0处）” 我在堆栈溢出中经历了很多解决方案。但无法获得适当的解决方案

Following is the code:
  public void execute() {
    if (mTableName.contentEquals("removed")) {
        String query = "Select * from removed";
        Cursor cursor = LODatabaseUtility.getInstance().cursorFromQuery(
                query);
        List<String> tableName = LODatabaseUtility.getInstance()
                .dataListfromCursor(cursor, "table_name");
        cursor = LODatabaseUtility.getInstance().cursorFromQuery(query);
        List<String> number = LODatabaseUtility.getInstance()
                .dataListfromCursor(cursor, "number");
        cursor = LODatabaseUtility.getInstance().cursorFromQuery(query);
        List<String> removedTimestamp = LODatabaseUtility.getInstance()
                .dataListfromCursor(cursor, "timestamp");
        if (number.size() == 0 || tableName.size() == 0) {
            cursor.close();
        }
        for (int i = 0; i < tableName.size(); ++i) {
            query = "Select timestamp from " + tableName.get(i) + " where "
                    + tableName.get(i) + "_id = " + number.get(i);
            cursor = LODatabaseUtility.getInstance().cursorFromQuery(query);
            String tableTimestamp = LODatabaseUtility.getInstance()
                    .dataStringfromCursor(cursor);
            try {

                SimpleDateFormat df = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss");
                Date removedDate, tableDate;
                removedDate = df.parse(removedTimestamp.get(i));
                tableDate = df.parse(tableTimestamp);

                if (removedDate.compareTo(tableDate) > 0) {
                    query = "Delete from " + tableName.get(i) + " where "
                            + tableName.get(i) + "_id = " + number.get(i);
                    LODatabaseUtility.getInstance().getDatabase()
                            .execSQL(query);
                }
            } catch (ParseException e) {
                Log.e("Sync", "" + e);
                e.printStackTrace();
            }
        }
        cursor.close();
    }
    getSyncTimeFromServer(mTableName);
}

I get the error pointing to the following line of code:
tableDate = df.parse(tableTimestamp);

仅对于特定表，时间戳值给出错误。对于我有时间戳值的其余表，正确插入值。任何帮助都是有用的
