The how Encode it? Is the entire url into them yet? I just tried it, something like this:
(To maintain secrecy, I put the URL replaced baidu)

 
String url = "http://baidu.com?name=han&content=hello world"; 
HttpGet get = new HttpGet (URLEncoder.encode (url, "UTF-8")); 

Then reported the anomaly:
java.lang.IllegalStateException:. Target host must not be null, or set in parameters scheme = null, host = null, path = http://baidu.com?name=han&content=hello world

Is not the whole url should not give Encode, ah? If only Encode behind the request, then the statement, and then how and in front of http://baidu.com fight together?

URLEncoder.encode (). This method of all non-alphanumeric characters changed to% sequence (in addition to spaces, underscores, hyphens, dots and asterisks), if the entire url to encode it, =, & these characters will be encoded . So the best part of the coding-by.

 
String query = URLEncode.encode ("name"); 
query + = "="; 
query + = URLEncode.encode ("han"); 
query + = "&"; 
query + = URLEncode.encode ("content"); 
query + = "="; 
query + = URLEncode.encode ("hello world"); 

String url = "? Http://baidu.com" + query;

For example http://baidu.com?name=han&content=hello world then this treatment
url = "http://baidu.com?name=han&content =" + URLEncoder.encode ("hello world", "utf-8");
