ILLEGALSTATEEXCEPTION : Target host must not be null

Question

I have tried multiple solutions here but none seem to work. I am getting error at String imageJsonStr = sh2.makeServiceCall(imgUrl[i], ServiceHandler.GET); There are no special characters in string and variable imageId is a string containing only numbers like '98546214265231'

                             imgUrl[i] = "https://graph.facebook.com/v2.2/"
                                        + imageId
                                        + "?access_token="
                                        + static_token;                                                 
                                try {

                                    try {
                                        imgUrl[i] = URLEncoder.encode(imgUrl[i],"UTF-8");
                                    } catch (UnsupportedEncodingException e) {
                                        // TODO Auto-generated catch block
                                        e.printStackTrace();
                                    }
                                    String imageJsonStr = sh2.makeServiceCall(
                                            imgUrl[i], ServiceHandler.GET);

log the value of imgUrl[i] after encoding it using URIEncoder .. — Dinesh Kannan

so u have to encode only your url parameters..the whole uri could not be encoded.. — Dinesh Kannan

I can also do it manually right? like this ?"access_token%33DCAAK43Qt9dQUBAF0ZC3LYE***..." — Harshil Pansare

Java URL encoding of query string parameters refer this.. you need not encode the entire url .. encode only the parmaters

do i need to encode Url even if there are no special characters after '?' ?

Dinesh Kannan Over a year ago

if there is no special characters then no need to encode..special chars includes spaces also..parameter encoding will be safe..

Harshil Pansare Over a year ago

I removed URLEncoder. I am getting "Illegal character in path at " starting of imageId .My imageId is a string containg all numbers

Dinesh Kannan Over a year ago

if your accesstoken doesn't have any spaces try this. don't do any encoding stuffs

Harshil Pansare Over a year ago

yes removing URLEncoder solved that problem. can you please tell me why am I getting "Illegal character in path" ?
