JSONObject cannot be converted to JSONArray in android

Question

I am new in android developing. I faced a error like:- JSON Object cannot be convert in jsonArray:-

My ProductInner.java:

public class ProductInner extends AppCompatActivity {

TextView textView;
ImageView imageView;
LinearLayout linearLayout;
String s,s1;
List<String> mainImage = new ArrayList<>();
List<String> outerlist = new ArrayList<>();

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.product_inner);

    textView = (TextView)findViewById(R.id.product_inner_page_product_name);
    imageView = (ImageView)findViewById(R.id.product_inner_page_product_main_image);
    linearLayout = (LinearLayout)findViewById(R.id.sub_images_show_section);

    new ProductInnerDisplay().execute("http://opencart.codeniques.com/shopping/?route=feed/web_api/product&id=80&key=test123$");
}

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

    ProgressDialog dialog;
    @Override
    protected void onPreExecute() {
        super.onPreExecute();

        dialog = new ProgressDialog(ProductInner.this);
        dialog.show();
    }

    @Override
    protected Void doInBackground(String... params) {
        try {
            HttpClient client = new DefaultHttpClient();
            HttpPost post = new HttpPost(params[0]);
            HttpResponse response = client.execute(post);

            int status = response.getStatusLine().getStatusCode();

            if(status==200){

                HttpEntity entity = response.getEntity();
                String data = EntityUtils.toString(entity);

                JSONObject jsonObject = new JSONObject(data);
               JSONArray jsonArray = jsonObject.getJSONArray("rproducts");
                JSONArray jsonArray1 = jsonObject.getJSONArray("productdata");

public class SetImage extends AsyncTask<String,Void,Bitmap>{

    ImageView bitmap;


    public SetImage(ImageView bitmap){
        this.bitmap = bitmap;
    }
    @Override

        super.onPreExecute();

    }

    @Override
    protected Bitmap doInBackground(String... params) {

        String urldisplay = params[0];
        Bitmap bitmap = null;
        try{
            InputStream in = new java.net.URL(urldisplay).openStream();
            bitmap = BitmapFactory.decodeStream(in);
        }catch (IOException e ) {
            e.getMessage();
            //    Log.e("Error :",e.getMessage());
        }
        return bitmap;
    }

    @Override
    protected void onPostExecute(Bitmap result) {
        bitmap.setImageBitmap(result);
        //super.onPostExecute(bitmap);
    }

}

}

My Json Array Link is here

My Logcat show this error:-

E/Error: Value {"id":"80","name":"Bag_80","model":"
","reward":"0","points":"0","image":"http://opencart.codeniques.com/shopping/image/cache/data/product/bag_81_1-1000x1000.JPG","images":["http://opencart.codeniques.com/shopping/image/cache/data/product/bag_80_2-80x80.JPG"],"price":1175,"minimum":"1","newprice":1163.25,"qty":4,"rating":0,"description":""} at productdata of type org.json.JSONObject cannot be converted to JSONArray`

productdata is not a JSONArray but a JSONObject, so you have to change

JSONArray jsonArray1 = jsonObject.getJSONArray("productdata");

to

JSONObject jsonObject1 = jsonObject.getJSONObjct("productdata");

As in log :

productdata of type org.json.JSONObject cannot be converted to JSONArray

means productdata key is used for JSONObject in response json of server instead of JSONArray .

So get productdata key value as JSONObject instead of JSONArray :

JSONObject jsonObject1 = jsonObject.getJSONObject("productdata");

You are getting productData as a JSONArray while it's a JsonObject which contains a JsonArray of images as I can see in the json link that you provided

JSONArray jsonArray1 = jsonObject.getJSONArray("productdata");

that line of code should be a JsonObject
