(Android Volley) JSONObject cannot be converted to JSONArray

Question

I had issue with parsing the JSON data in android.

my android code

JsonObjectRequest jsonObjectRequest = new JsonObjectRequest(Request.Method.GET, server_url,null,
            new Response.Listener<JSONObject>() {
                @Override
                public void onResponse(JSONObject response) {
                    try {

                JSONArray jsonArray1=response.getJSONArray("employee");

                        for(int i=0;i<jsonArray1.length();i++)
                        {
                  JSONObject employe=jsonArray1.getJSONObject(i);

                 Log.d(TAG, "onResponse emp: "+employe.getString("name"));
                        }
                        }
                    catch (JSONException e) {
                        e.printStackTrace();
                    }
                }
            }

my JSON data

{"orgs":[{"id":1551,"employeeId":1501,"orgId":"1151","employeeOrgMembershipStatus":"MEMBER","employeeRole":"SUPER_ADMIN","lMb":"alvin","lMd":"2019-06-01T05:41:00Z"}],"employee":{"id":1501,"employeeStatus":"ACTIVE","userId":"SU9iegDhr3b9r3gCUZzXl9eQjEJ2","name":"Alvin J Babu","cB":"alvin","cD":"2019-06-24T05:41:00Z","lMb":"alvin","lMd":"2019-06-27T05:41:00Z","computedTotalActivityScore":5,"stars":2,"jobTitle":"Developer","visibility":"ORGANIZATION","asset":null,"reportsTo":null},"teams":[{"id":1601,"employeeId":1501,"teamId":"1251","employeeTeamMembershipStatus":"MEMBER","lMb":"alvin","lMd":"2019-06-25T05:41:00Z"}],"status":1}

i need to parse the employee array and get name from it.

Firstly use websites like jsonprettyprint.com to read the json easily.

This is your json in a much more readable form:

{
  "orgs": [
    {
      "id": 1551,
      "employeeId": 1501,
      "orgId": "1151",
      "employeeOrgMembershipStatus": "MEMBER",
      "employeeRole": "SUPER_ADMIN",
      "lMb": "alvin",
      "lMd": "2019-06-01T05:41:00Z"
    }
  ],
  "employee": {
    "id": 1501,
    "employeeStatus": "ACTIVE",
    "userId": "SU9iegDhr3b9r3gCUZzXl9eQjEJ2",
    "name": "Alvin J Babu",
    "cB": "alvin",
    "cD": "2019-06-24T05:41:00Z",
    "lMb": "alvin",
    "lMd": "2019-06-27T05:41:00Z",
    "computedTotalActivityScore": 5,
    "stars": 2,
    "jobTitle": "Developer",
    "visibility": "ORGANIZATION",
    "asset": null,
    "reportsTo": null
  },
  "teams": [
    {
      "id": 1601,
      "employeeId": 1501,
      "teamId": "1251",
      "employeeTeamMembershipStatus": "MEMBER",
      "lMb": "alvin",
      "lMd": "2019-06-25T05:41:00Z"
    }
  ],
  "status": 1
}

Inside JSON anything which is bounded by {} is a JSONObject and anything which is bounded by [] is a JSONArray.

In your case as you can see in the above JSON the key "employee" has a JSONObject value not JSONArray as you have written in your code.

After you get "employee" key's JSONObject you can directly get the "name" String from it using employee.getString("name").

Your code after making above changes will look something like this:

public void onResponse(JSONObject response) {
    try {
        JSONObject employee=response.getJSONObject("employee");
        String employeeName=employee.getString("name");
        Log.d(TAG, "onResponse emp: "+employeeName);
    }
    catch (JSONException e) {
        e.printStackTrace();
    }
}
