android httpGet issue

Question

I am trying to execute the following link using following code:

class httpget{
HttpGet httpGet=null;

public void linkexecute(){
String url="http://<server>/<path>/action=send&msg=new message";
httpGet= new HttpGet(url); // line 1
....
}

at line 1 it is giving error "Illegal arguement exception"    
java.lang.IllegalArgumentException: Illegal character in query at index 77: http://<server>/<path>/sms.json?action=send&msg=new message    
at java.net.URI.create(URI.java:970)    
at org.apache.http.client.methods.HttpGet.<init>(HttpGet.java:75)    
at com.sms.login.LoginService.sendSms(LoginService.java:143)

Whereas there's no error for given below URL which has no gaps in words of "msg="

String url="http://<server>/<path>/action=send&msg=newmessage";

How can I resolve the issue of gap in words in URL?

Answer 1

Here, i give you one function that will remove all invalid characters from the url . Please pass your url in this function and you will get a new url with encoded strings.

public static String convertURL(String str) {

    String url = null;
    try{
    url = new String(str.trim().replace(" ", "%20").replace("&", "%26")
            .replace(",", "%2c").replace("(", "%28").replace(")", "%29")
            .replace("!", "%21").replace("=", "%3D").replace("<", "%3C")
            .replace(">", "%3E").replace("#", "%23").replace("$", "%24")
            .replace("'", "%27").replace("*", "%2A").replace("-", "%2D")
            .replace(".", "%2E").replace("/", "%2F").replace(":", "%3A")
            .replace(";", "%3B").replace("?", "%3F").replace("@", "%40")
            .replace("[", "%5B").replace("\\", "%5C").replace("]", "%5D")
            .replace("_", "%5F").replace("`", "%60").replace("{", "%7B")
            .replace("|", "%7C").replace("}", "%7D"));
    }catch(Exception e){
        e.printStackTrace();
    }
    return url;
}

You should definitely use URLEncoder.encode(String, String)
