Answer 1

Whyt don't you use RIM's URLEncodedPostData?

private String encodeUrl(String hsURL) {
    URLEncodedPostData urlEncoder = new URLEncodedPostData("UTF-8", false);
    urlEncoder.setData(hsURL);
    hsURL = urlEncoder.toString();
    return hsURL;
}

Great solution but not portable. Given he wants to run his software on a different mobile, he'll be asking the same question again. Best is to steer clear of classes which only run on one platform. – Quintin

Can't tell for sure... In this case you're right, cause it's not platform dependent functionality. But still simple is good, implement it when they ask you. – Accentor

He doesn't actually say he's writing cross-platform mobile code so in this case I'd side with coldice - it seems safer to me (less likely to introduce bugs) to use a native API over a homebrew approach. – Egwin

Maybe I'm misunderstanding the question here, but I don't think this answer does what the question asks, at all. URLEncodedPostData is meant for URL encoding sets of POST params (key/value pairs), to be written as content bytes in a POST request. It looks to me (and to a couple other answers here) that the OP is asking to encode the URL itself. For example, http://maps.google.com/?addr=123 Main St, New York, NY -> http://maps.google.com/?addr=123+Main+St,+New+York,+NY. This doesn't do that. – Finnie

I am not able to get a proper URL encoded string from this solution : here is my link maps.google.com/maps?saddr=HD5&DT4 8TA – Terryterrye

here you go ;^)

public static String URLencode(String s)
{
    if (s!=null) {
        StringBuffer tmp = new StringBuffer();
        int i=0;
        try {
            while (true) {
                int b = (int)s.charAt(i++);
                if ((b>=0x30 && b<=0x39) || (b>=0x41 && b<=0x5A) || (b>=0x61 && b<=0x7A)) {
                    tmp.append((char)b);
                }
                else {
                    tmp.append("%");
                    if (b <= 0xf) tmp.append("0");
                    tmp.append(Integer.toHexString(b));
                }
            }
        }
        catch (Exception e) {}
        return tmp.toString();
    }
    return null;
}

Answer 4

the reply using "URLEncodedPostData" above is incorrect. Corrected sample:

public static String encodeUrl(Hashtable params)
{
    URLEncodedPostData urlEncoder = new URLEncodedPostData("UTF-8", false);
    Enumeration keys = params.keys();
    while (keys.hasMoreElements()) {
        String name = (String) keys.nextElement();
        String value = (String) params.get(name);
        urlEncoder.append(name, value);
    }

    String encoded = urlEncoder.toString();
    return encoded;
}

Cheers!
