what is the problem, I think it's in string encoding ?!

Update:

The code is here

//Download text -------------------------------------------------------------
private String DownloadText(String urlString){
    InputStream in = null;
    StringBuilder sb = new StringBuilder();
    try{
        in = OpenHttpConnection(urlString);
        BufferedReader br = new BufferedReader(new InputStreamReader(in));
        String line="";
        while((line = br.readLine())!= null){
            sb.append(line);
        }
    }catch(IOException ex){

    }
    return sb.toString();
}

//Parse JSON text -----------------------------------------------------------
private FBUser pasreJSON(String url){
    FBUser user = null;
    JSONArray json;
    Log.d("JSON----------------",DownloadText(url));
    try {
        user = new FBUser();
        json = new JSONArray(DownloadText(url));
        for(int i=0;i<json.length();i++){
            JSONObject object = json.getJSONObject(i);
            user.id = object.getString("id");
            user.name = object.getString("name");
            user.first_name = object.getString("first_name");
            user.last_name = object.getString("last_name");
            user.link = object.getString("link");
            user.username = object.getString("username");
            user.gender = object.getString("gender");
            user.locale = object.getString("locale");
        }
    } catch (JSONException e) {
        e.printStackTrace();
    }

    return user;
}

Please include your source code – Jason Robinson Apr 24 '12 at 21:20
I'm not sure if the JSONArray can parse a string that does not contain a bunch of primitives - the elements of your array are name-value pairs. EDIT: so please inclued your source code, like Jason already mentioned – axel Apr 24 '12 at 21:23

at this line:

json = new JSONArray(DownloadText(url));

change it to:

json = new JSONObject(DownloadText(url));

And obviously change json to be a JSONOBject

Looks like pit.opensource.readjson.D0ReadJSONWebServiceActivity.pasreJSON is trying to decode a facebook user info repsonse into a JSONArray type.

You should be storing it in a JSONObject instead.

The error is that this is not a JSONArray, but a JSONObject. arrays are surrounded by square brackets, while objects by curly brackets.

Take a look at json.org, the official site.

Try

JSONObject object = new JSONObject (DownloadText(url));
                     user.id = object.getString("id");   
               user.name = object.getString("name");  
                user.first_name = object.getString("first_name"); 
                 user.last_name = object.getString("last_name"); 
                 user.link = object.getString("link");         
         user.username = object.getString("username");        
          user.gender = object.getString("gender");            
      user.locale = object.getString("locale");
