Method

StringshortenContent(String s, int maxLength)
shorten Content 
if (s.length() > maxLength) {
    return s.substring(0, maxLength - 3) + "...";
} else {
    return s;
StringshortenCount(final long count)
Changes a large number into a binary postfixed version. 
int unit = 1000;
if (count < unit) {
    return Long.toString(count);
int exponential = (int) (Math.log(count) / Math.log(unit));
char postfix = "KMBT".charAt(exponential - 1);
return String.format("%.1f%c", (count / Math.pow(unit, exponential)), postfix);
StringshortenCount(int count)
shorten Count 
int shortCount = count;
String postFix = "";
if (count >= 1000000) {
    shortCount /= 1000000;
    postFix = "M";
} else if (count >= 1000) {
    shortCount /= 1000;
    postFix = "k";

Start by removing all vowels, then pull 1 letter at a time off the end of each _ separated segment, go until it is less than or equal to the desired length 
StringBuilder dbBuf = new StringBuilder(dbName);
if (dbBuf.length() > desiredLength) {
    for (int i = dbBuf.length() - 1; i > 0; i--) {
        if (dbBuf.charAt(i - 1) == '_') {
