Question

I am writing an Android app and need some help.

I have a string that contains a URL. Sometimes I get extra text before the url and need to trim that off.

I get this “Some cool sitehttp://somecoolsite.com”

And want this “http://somecoolsite.com”

First, I need to detect if the string does not start with http:// and then if not, I need to trim everything in front of http://

Is there an easy way to do this?

I can do the first part.

if (url.startsWith("http://") == false) {
url.replace("", replacement) 
}

Any help?

Use this:

if(inputURL.contains("http://")
    inputURL = inputURL.substring(inputURL.indexOf("http://"));
