illeal unquoted character (CTRL-CHAR, code 9)): has to be escaped using backslash to be included instring value: nested exception is com.fasterxml.jackson.core.sonParseException: Illeeal uncuoted character

抱歉，这个错误信息是由于字符串中存在非法的字符导致的。它提示你需要在字符串中使用反斜杠转义这个字符。例如，如果字符串中包含引号，你需要使用反斜杠来转义它，像这样：

String str = "This is a string with a \"quote\" character.";

如果你在代码中使用了 JSON 解析器，那么这个错误可能是由于 JSON 字符串中存在非法字符导致的。你需要检查 JSON 字符串中是否有非法字符，并进行相应的转义。

: error: Parse error. Expected a command name, got unquoted argument with text "release-build:".

这个错误通常出现在Makefile中，当你试图使用未加引号的文本作为命令名或者参数时。"Parse error. Expected a command name, got unquoted argument with text 'release-build':"的意思是解析阶段遇到了问题，它期望看到的是一个命令名，但是遇到了未加引号的字符串"release-build:"，这通常用于定义一个新的目标或任务。

比如，可能是你尝试这样编写Makefile规则：

release-build: some-targets
    # ... your commands here

在这个例子中，`release-build:`看起来像一个目标，但实际上应该放在等号后面，像是这样：

release-build:
    some-targets
    # ... your commands here

或者是：

.PHONY: release-build
release-build:
    some-targets
    # ... your commands here

如果你的规则不是这样的，检查一下是否在不期望的地方用了未加引号的文本作为了命令名或参数。如果还是不清楚问题出在哪里，提供更多的上下文可能会有帮助。

可以通过使用定时器或者Handler来实现每秒更新一次秒数。具体实现方法如下：

1.在构造函数或onCreate()方法中初始化定时器或Handler。

2.定时器或Handler中的回调方法中，调用invalidate()方法刷新UI界面。

示例代码如下：

private final CharSequence getSmallTime() {
    Context context = getContext();
    boolean is24 = DateFormat.is24HourFormat(context);
    LocaleData d = LocaleData.get(context.getResources().getConfiguration().locale);

    final char MAGIC1 = '\uEF00';
    final char MAGIC2 = '\uEF01';

    SimpleDateFormat sdf;
    String format = is24 ? d.timeFormat24 : d.timeFormat12;

    // Add seconds to the format string
    format += ":ss";

    if (!format.equals(mClockFormatString)) {
        /*
         * Search for an unquoted "a" in the format string, so we can
         * add dummy characters around it to let us find it again after
         * formatting and change its size.
         */
        if (AM_PM_STYLE != AM_PM_STYLE_NORMAL) {
            int a = -1;
            boolean quoted = false;
            for (int i = 0; i < format.length(); i++) {
                char c = format.charAt(i);
                if (c == ''') {
                    quoted = !quoted;
                }
                if (!quoted && c == 'a') {
                    a = i;
                    break;
                }
            }
            if (a >= 0) {
                // Move a back so any whitespace before AM/PM is also in the alternate size.
                final int b = a;
                while (a > 0 && Character.isWhitespace(format.charAt(a-1))) {
                    a--;
                }
                format = format.substring(0, a) + MAGIC1 + format.substring(a, b) + "a" + MAGIC2 + format.substring(b + 1);
            }
        }
        mClockFormat = sdf = new SimpleDateFormat(format);
        mClockFormatString = format;
    } else {
        sdf = mClockFormat;
    }

    mCalendar.setTimeInMillis(System.currentTimeMillis()); // 更新Calendar对象

    String result = sdf.format(mCalendar.getTime());

    if (AM_PM_STYLE != AM_PM_STYLE_NORMAL) {
        int magic1 = result.indexOf(MAGIC1);
        int magic2 = result.indexOf(MAGIC2);
        if (magic1 >= 0 && magic2 > magic1) {
            SpannableStringBuilder formatted = new SpannableStringBuilder(result);
            if (AM_PM_STYLE == AM_PM_STYLE_GONE) {
                formatted.delete(magic1, magic2+1);
            } else {
                if (AM_PM_STYLE == AM_PM_STYLE_SMALL) {
                    CharacterStyle style = new RelativeSizeSpan(0.7f);
                    formatted.setSpan(style, magic1, magic2, Spannable.SPAN_EXCLUSIVE_INCLUSIVE);
                }
                formatted.delete(magic2, magic2 + 1);
                formatted.delete(magic1, magic1 + 1);
            }
            return formatted;
        }
    }
    return result;
}

在构造函数或onCreate()方法中添加以下代码：

// 定义Handler
private Handler mHandler = new Handler();

// 定义Runnable
private Runnable mRunnable = new Runnable() {
    @Override
    public void run() {
        invalidate(); // 刷新UI界面
        mHandler.postDelayed(mRunnable, 1000); // 每秒执行一次
    }
};

// 在构造函数或onCreate()方法中启动定时器
mHandler.postDelayed(mRunnable, 1000);

这样就可以实现每秒更新秒数了。
