Android Syntax Highlighting?

I managed to create a syntax highlighter for Android, based on the Prettify. It was easy, actually, when I found the Java Prettify. Just download it (sadly, it is not published for maven) and add its jar to the build path of you application.

The syntax highlighter I created based on it:

public class PrettifyHighlighter {
    private static final Map<String, String> COLORS = buildColorsMap();

    private static final String FONT_PATTERN = "<font color=\"#%s\">%s</font>";

    private final Parser parser = new PrettifyParser();

    public String highlight(String fileExtension, String sourceCode) {
        StringBuilder highlighted = new StringBuilder();
        List<ParseResult> results = parser.parse(fileExtension, sourceCode);
        for(ParseResult result : results){
            String type = result.getStyleKeys().get(0);
            String content = sourceCode.substring(result.getOffset(), result.getOffset() + result.getLength());
            highlighted.append(String.format(FONT_PATTERN, getColor(type), content));
        }
        return highlighted.toString();
    }

    private String getColor(String type){
        return COLORS.containsKey(type) ? COLORS.get(type) : COLORS.get("pln");
    }

    private static Map<String, String> buildColorsMap() {
        Map<String, String> map = new HashMap<>();
        map.put("typ", "87cefa");
        map.put("kwd", "00ff00");
        map.put("lit", "ffff00");
        map.put("com", "999999");
        map.put("str", "ff4500");
        map.put("pun", "eeeeee");
        map.put("pln", "ffffff");
        return map;
    }
}

The colors of the syntax are hardcoded, but may be also set by i.e. application preferences. In order to display a Java source code in a TextView, just do:

// code is a String with source code to highlight
// myTextView is a TextView component
PrettifyHighlighter highlighter = new PrettifyHighlighter();
String highlighted = highlighter.highlight("java", code);
myTextView.setText(Html.fromHtml(highlighted));

The Java Prettify library made my application around 50kB bigger.
