Getting JSON.typeMismatch trying to convert string coming from an HTTP Get to JSON object

I have looked at multiple other answers here but I still have not been able to resolve this issue.

I call a PHP restful server to get a JSON string from a database. Here is the log output of the string that comes back:

"{\"pat_list\":[{\"id\":\"1\",\"name\":\"John Deere\",\"gender\":\"M\",\"child\":\"N\",\"email\":\"\",\"patientid\":\"12657\",\"pridiag\":\"Sick\"}]}"

This looks like valid JSON (it validates) and looks properly escaped to me (it was created using json_encode in PHP on the server)

However, when I try to execute this code:

    if (json_pat_list != null) {


        try {

            JSONObject jsonObj = new JSONObject(json_pat_list);

I get:

W/System.err﹕ org.json.JSONException: Value {"pat_list":[{"id":"1","name":"John Deere","gender":"M","child":"N","email":"","patientid":"12657","pridiag":"Sick"}]} of type java.lang.String cannot be converted to JSONObject ... W/System.err﹕ at org.json.JSON.typeMismatch(

Can anyone see what I am missing here?


Your code seems legit. As far as I can see. What I can suggest is that because you say that it is generated on the PHP server, it might be putting in characters that malformat the string completely.

There are 2 things I can suggest:

    if (json_pat_list != null) {


    //Either this

    String formattedString = json_pat_list.replaceAll("\n", "\\n");

     //or you can do this
     String formattedString = json_pat_list.substring(s.indexOf("{")); 

    try {

        JSONObject jsonObj = new JSONObject(json_pat_list);
