Here you can use following classes to parse your Response:
Create Two classes:
1. DepartmentAndCategory
2. ProductsAndDeals
//DepartmentAndCategory class
public class DepartmentAndCategory {

How to parse Array of Objects in Android

I am parsing the following json response but there is some problem in parsing,the code I'm trying is not parsing and I am not getting any exception or response.
The code that I had applied to parse it is:
ArrayList<Model_BarcodeDetail> DownloadBarcode(String api_token) {
ArrayList<Model_BarcodeDetail> barcodeList = new ArrayList<Model_BarcodeDetail>();
HttpClient httpClient = new DefaultHttpClient();
HttpPost postRequest = new HttpPost(Utility.BASE_URL
+ "?q=webservice/barcode_list&token=" + api_token +"&page="+"1"
+ "&return=json");
String url = Utility.BASE_URL
+ "?q=webservice/barcode_list&token=" + api_token +"&page="+"1"
+ "&return=json";
System.out.println("======url::"+url);
String result = "";
ArrayList<Model_BarcodeDetail> group_list = null;
ArrayList<Model_BarcodeList_Child> child_list = null;
try {
group_list = new ArrayList<Model_BarcodeDetail>();
ResponseHandler<String> responseHandler = new BasicResponseHandler();
result = httpClient.execute(postRequest, responseHandler);
JSONObject root = new JSONObject(result);
JSONObject obj = root.getJSONObject("");
System.out.println("====objjjj: "+obj.toString());
JSONArray arraylist=obj.names();
for (int i = 0; i < arraylist.length(); i++) {
child_list = new ArrayList<Model_BarcodeList_Child>();
JSONObject jsonObj = arraylist.getJSONObject(i);
System.out.println("---json" + jsonObj);
Model_BarcodeDetail data = new Model_BarcodeDetail();
data.setReference((jsonObj.getString("ref")));
System.out.println("======refinprsing--"+data.getReference());
// data.setName((jsonObj.getString("name")));
// data.setDescription((jsonObj.getString("desc")));
// data.setPrice((jsonObj.getString("price")));
// data.setTotal(data.getPrice().trim());
// data.setFixedTotal(data.getPrice().trim());
JSONArray obj2 = jsonObj.getJSONArray("barcodes");
for (int j = 0; j < obj2.length(); j++) {
JSONObject json = obj2.getJSONObject(j);
System.out.println("---json" + json);
Model_BarcodeList_Child data2 = new Model_BarcodeList_Child();
data2.setBarcode((json.getString("barcode")));
System.out.println("=======barcodeinparsing: "+data2.getBarcode());
data2.setColor((json.getString("color")));
data2.setSize((json.getString("size")));
data2.setPrice(json.getString("price"));
data2.setStock(json.getString("stock"));
data2.setAlis_code(json.getString("alias_code"));
child_list.add(data2);
}
data.setChildItems(child_list);
group_list.add(data);
}

According to your json Response do parsing like below
JSONObject root = new JSONObject(result);
JSONArray array = root.getJSONArray("array");
String boolean = root.getString("boolean");
String null= root.getString("null");
String number= root.getString("number");
String string = root.getString("string");
JSONArray array_1 = root.getJSONArray("object");
first check your result is not getting null ? please check log.

Based on the json provided change this:
JSONObject root = new JSONObject(result);
JSONObject obj = root.getJSONObject("");
System.out.println("====objjjj: "+obj.toString());
JSONArray arraylist=obj.names();
To this:
JSONObject root = new JSONObject(result);
JSONArray arraylist= root.names();
for (int i = 0; i < arraylist.length(); i++) {
child_list = new ArrayList<Model_BarcodeList_Child>();
JSONObject jsonObj = root.getJSONObject(arrayList.getString(i));
I would also add a check to see if the name equals pager, in that case continue;

Here is solution
JSONObject root = new JSONObject(result);
if(root != null){
Iterator iter = root.keys();
while (iter.hasNext()){
try {
String key = (String) iter.next();
JSONObject itemObject = root.getJSONObject(key);
} catch (JSONException e) {
}
}
}

Try this code
Bitmap src = BitmapFactory.decodeResource(getResources(), R.drawable.yourimage); // the original file yourimage.jpg i added in resources
Bitmap dest = Bitmap.createBitmap(src.getWidth(), src.getHeight(), Bitmap.Config.ARGB_8888);
String yourText = "3+5 = ?";
Canvas cs = new Canvas(dest);
Paint tPaint = new Paint();
tPaint.setTextSize(35);
tPaint.setColor(Color.BLUE);
tPaint.setStyle(Style.FILL);
cs.drawBitmap(src, 0f, 0f, null);
float height = tPaint.measureText("yY");
float width = tPaint.measureText(yourText);
float x_coord = (src.getWidth() - width)/2;
cs.drawText(yourText, x_coord, height+15f, tPaint); // 15f is to put space between top edge and the text, if you want to change it, you can
try {
dest.compress(Bitmap.CompressFormat.JPEG, 100, new FileOutputStream(new File("/sdcard/ImageAfterAddingText.jpg")));
// dest is Bitmap, if you want to preview the final image, you can display it on screen also before saving
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
This code generates image from custom text
Don't forget to add permission in Manifest file
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

You have several options. A couple of them:
Use a Map
Keep a Map where the keys is the Question ID in your data base. The values stored in the map for each key could be the Images Views (loaded as resources for instance)
Add a field in DB
Add a field with the relative path of the image and load the corresponding image for every question.
You can store the path as an String in your DB and then recover the image as this:
File imgFile = new File("/path/of/image/image.jpg");
if(imgFile.exists()){
Bitmap myBitmap = BitmapFactory.decodeFile(imgFile.getAbsolutePath());
// This image view is defined as a resource.... just set the bitmap
ImageView myImage = (ImageView) findViewById(R.id.anyImageView);
myImage.setImageBitmap(myBitmap);
}

Thank you very much for your help.

Replace
JSONObject discoverObj = (JSONObject) discoverArray.opt(i);
with
JSONObject discoverObj = discoverArray.getJSONObject(i);
Review the below code

JSONArray discoverArray = (JSONArray) response.optJSONArray("users");
ArrayList<Discover> discovers = new ArrayList<Discover>();

discover.setMutualFriend(discoverObj.optInt("mutualFriend"));
