The line which I am getting this error is : 

 JSONObject object = new JSONObject(result);

Here is my code:

 import android.os.AsyncTask;
 import android.util.Log;

 import org.json.JSONArray;
 import org.json.JSONException;
 import org.json.JSONObject;

 import java.io.IOException;
 import java.io.InputStream;
 import java.io.InputStreamReader;
 import java.net.HttpURLConnection;
      import java.net.MalformedURLException;
 import java.net.URL;


 public class FlightDataModel extends AsyncTask<String, Void, String>{


    private String data = "https://api.themoviedb.org/3/movie/550?api_key=f1d314280284e94ff7d1feeed7d44fdf&callback=test";

URL mURL;
HttpURLConnection mHttpURLConnection;
String result = "" ;
String main;
JSONArray mArray = null;
private String mImageIcon;
private String movieTitle;
private String movieDesc;
private String movieRating;


@Override
protected String doInBackground(String... strings) {

    try {

        Log.d("FlightDemo", "doInBackground method called");
        mURL = new URL(data);
        mHttpURLConnection = (HttpURLConnection)mURL.openConnection();
        mHttpURLConnection.connect();
        InputStream inputStream = mHttpURLConnection.getInputStream();
        InputStreamReader inputStreamReader = new InputStreamReader(inputStream);

        int data = inputStreamReader.read();

        while (data != -1){

            char current = (char) data;

            result += current;

           data = inputStreamReader.read();

        }



    } catch (MalformedURLException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    }


    return result;
}

@Override
protected void onPostExecute(String s) {

    //What to do when the doInBackground Method is executed..

    try {

        //JSONObject json = new JSONObject(result);

        JSONObject object = new JSONObject(result);

       // JSONArray array = new JSONArray(result);



        Log.d("FlightDemo", object.toString());




    } catch (JSONException e) {
        e.printStackTrace();
    }


    super.onPostExecute(s);
}

public String getImageIcon() {
    return mImageIcon;
}

public String getMovieTitle() {
    return movieTitle;
}

public String getMovieDesc() {
    return movieDesc;
}

public String getMovieRating() {
    return movieRating;
}

public String getData() {
    return data;
}
 }

I have been working on this code for a few days.. I am a beginner in android app development. So any help is much appreciated.

Many Thanks

  • Can you please check if you string is in the format new JSONObject("{your string}"). Same question has been asked before https://stackoverflow.com/questions/10267910/jsonexception-value-of-type-java-lang-string-cannot-be-converted-to-jsonobject – user8271644 Jul 18 '17 at 19:17
  • Looks like you're new here. Welcome! People are reluctant to help if you don't show what you have tried and reduce the code you present to the bare minimum amount that still shows the issue. – zetavolt Jul 18 '17 at 22:50

There might be some special/invisible characters in your json string. You can print the result string before converting to JSONObject or open it in some editor to display hidden characters and see if the json is proper. You can also use UTF 8 standards for the input stream.
