    if (dateStr.equals("")) {
        return "";
    }
    Log.d("date", dateStr + "---" + sourceFormat + "---" + targetFormat);
    SimpleDateFormat form = new SimpleDateFormat(sourceFormat);
    Date date = null;
    try {
        date = form.parse(dateStr);
    } catch (Exception e) {
        e.printStackTrace();
    }

You need to use 'HH' instead of 'hh' in sourceFormat if your source time in 24 hours format. — Haresh Chhelana, May 31 '18 at 06:05
@AkshayBarodia if it's not working then why you accept Venki WAR answer. — Haresh Chhelana, May 31 '18 at 06:39

private static final String sourceFormat = "hh:mm:ss";

change to

private static final String sourceFormat = "HH:mm:ss";

It's working I checked in My IDE

private static final String sourceFormat = "HH:mm:ss";
    private static final String targetFormat = "hh:mm a";

public static String convertTimeFormat(String dateStr)  {

        if (dateStr.equals("")) {
            return "";
        }
        Log.d("date", dateStr + "---" + sourceFormat + "---" + targetFormat);

        **SimpleDateFormat form = new SimpleDateFormat(sourceFormat, Locale.US);**


        Date date = null;
        try {
            date = form.parse(dateStr);
        } catch (ParseException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

        **SimpleDateFormat postFormater = new SimpleDateFormat(targetFormat, Locale.US);**

        String newDateStr = postFormater.format(date);
       Log.d("Lead Response", newDateStr);
        return newDateStr;
    }
