above sample json array , how to get the 204, 203 and 202?

No, current String is JSONObject instead of JSONArray. you should get Iterator using JSONObject. keys () if inner JSONObject keys dynamic as:

JSONObject issueObj = new JSONObject(jsonContent);
Iterator iterator = issueObj.keys();
   while(iterator.hasNext()){
    String key = (String)iterator.next();
    JSONObject issue = issueObj.getJSONObject(key);

    //  get id from  issue
        String _pubKey = issue.optString("id");
    }
