无法在 Android 中将 CallLog.calls.DATE 转换为日期格式？

Question

我正在使用 Content Provider 从 CallLog.Calls.Date 获取日期，但出现以下错误

java.lang.NumberFormatException: For input string: "date"
        at java.lang.Long.parseLong(Long.java:594)
        at java.lang.Long.parseLong(Long.java:636)

        at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:1130)

这是我用来将日期（以毫秒为单位）转换为特定日期格式的代码

        SimpleDateFormat formatter = new SimpleDateFormat("dd/MM/yyyy hh:mm:ss.SSS");
        Calendar calendar = Calendar.getInstance();
        calendar.setTimeInMillis(Long.parseLong(CallLog.Calls.DATE));
        String convertedDate = formatter.format(calendar.getTime());

解决此问题并消除此错误的解决方案是什么
