What I have tried:

public String URL = "http://localhost:61511:8010/api/Feedback/5" ;
protected void onCreate(Bundle savedInstanceState) {
   final Button start =(Button)findViewById(;
   final TextView textView =(TextView)findViewById(;
   final EditText ee =(EditText)findViewById( ;
    start.setOnClickListener(new View.OnClickListener() {
        public void onClick(View v) {
            JsonObjectRequest jsonObjectRequest = new JsonObjectRequest(Request.Method.GET, URL, null, new Response.Listener<JSONObject>() {
                public void onResponse(JSONObject response) {
                    try {
                        JSONArray jsonArray = response.getJSONArray("User");
                        for(int i= 0 ;i < jsonArray.length();i++){
                            JSONObject User = jsonArray.getJSONObject(i);

                    }catch (JSONException e ) {

                    new Response.ErrorListener() {
                        public void onErrorResponse(VolleyError error) {
                            Log.e("Volley", "ERROR");

In the onResponse() method, does response actually contain the backslash characters? If not, then it should look something like:

    "OfGroup":"a "
And your code to extract the various keys would look something like:

String userID = response.getString("UserID");
String userName = response.getString("UserName");
String pwd = response.getString("Password");

It looks like you're storing passwords in plain text. Don't do that!

There is NEVER a valid reason to return the user's password to them.

And given the other details you're returning, I hope you've added code on the server to ensure that the request is coming from an authenticated user who has permission to view those details. If not, you're going to get hammered with fines for breaching GDPR and other data protection laws.

Volley is just an interface to manage the network traffic in a managed way, it won't do much for you to parse and generate the response. You would need to use the library to parse the JSON—see this link on Android Developer[^] website to see how they are demonstrating this—and as for SQLite, Android has another amazing tool, Room database ORM, in this way, you will be using everything by Google starting with request management by Volley, then Gson and then lastly Room to persist the data in the database.

I recommend that you use Gson to parse this String to objects. However this also requires that you first create a class that matches the signature of that JSON document, the following is what you need,
{"UserID\":5,\"UserName\":\"asd\",\"Password\":\"asd\",\"Email\":\"ss@asd\",\"PhoneNumber\":\"1213\",\"Logtit\":0.0,\"Latitle\":0.0,\"OfGroup\":\"a \"}"
public class User {
    // I won't go in encapsulation, you can set these to private
    // and create getter/setters.
    public int UserId;
    public String UserName;
    public String Password;
    public String Email;
    public String PhoneNumber;
    public double Logtit;
    public double Latitle;
    public String OfGroup;
Now you can go ahead and use Gson to parse the JSON document as an object of User type.
GsonBuilder builder = new GsonBuilder();
Gson gson = builder.create();

// Capture the JSON document as a variable, I do not know where and how you do that.
User user = gson.fromJson(jsonString, User.class);
This way, you can convert the JSON to a runtime object. See here for an example of this,[^]
