Implement it in try catch block also check your response string if it has expected value:

try {
    JSONObject jsonObject = new JSONObject(response);
    JSONObject responseObj = jsonObject.getJSONObject("Response");
    message = responseObj.getString("message");
    String url = responseObj.getString("url");
    orgId = responseObj.getString("cor");
    orgName = responseObj.getString("headerMsg");
    String subheadMsg = responseObj.getString("subheadMsg");

} catch (JSONException e) {
    e.printStackTrace();
    Toast.makeText(getApplicationContext(), "Error: " + e.getMessage(),
                    Toast.LENGTH_LONG).show();              
}
