  • 0

I am trying to get a java.net.URI object from a String. The string has some characters which will need to be replaced by their percentage escape sequences. But when I use URLEncoder to encode the String with UTF-8 encoding, even the / are replaced with their escape sequences.

How can I get a valid encoded URL from a String object?

http://www.google.com?q=a b gives http%3A%2F%2www.google.com… whereas I want the output to be http://www.google.com?q=a%20b

Can someone please tell me how to achieve this.

I am trying to do this in an Android app. So I have access to a limited number of libraries.

  1. You might try: org.apache.commons.httpclient.util.URIUtil.encodeQuery in Apache commons-httpclient project

    Like this (see URIUtil):

    URIUtil.encodeQuery('http://www.google.com?q=a b')

    will become:

    http://www.google.com?q=a%20b

    You can of course do it yourself, but URI parsing can get pretty messy…
