Question

But my description value has lot of spaces and line breaks. i have to rectify while passing that value as url without spaces. but it will posted on the facebook wall with the spaces. Is it possible?Any Idea.

Answer 1

When generating your URL parameters, use

 paramString = URLEncoder.encode(paramString, "utf-8");

Answer 2

I'm not sure if you're asking how to properly encode the URL so it has no whitespace, or if you want to remove line breaks from a string. If you want to remove line breaks from a string, do this:

yourString.replaceAll("\n", "");

Answer 3

I asked something similar a while ago. Maybe the answer to that question helps you some way.
