Insert Record JSON Android in localhost environment


  • This tutorial is the continuation of Login JSON Android using Login Activity
  • STEP 1: Preparing the online database facilities in localhost.
  • STEP 2: Preparing the PHP script to insert a new record.
  • STEP 3: Coding of The Android client



STEP 1: Preparing the online database facilities in localhost.

Our Localhost environment is on Xampp as usual.

Importing the database to the online database. Download the full code below and you will find the SQL-dump file. Import the file and it will create a database named training.


STEP 2: PHP script

Preparing the PHP script to insert a new record. We have lots of files, insertrecord.php are the one in use for this tutorial.

// include connect class
require_once __DIR__ . '/connect.php';

// connecting to db
$db = new DB_CONNECT();

//capture all values from client

//sql query
$q = mysql_query("INSERT INTO a_training VALUES ('$id','$trainingname', '$website','$contact','$trainingdesc')");

//echo (mysql_error());

if ($q==true) {
    // match found
	//send success to client if save went thru
		echo "success";

	}//end match found

	else{//no match found
		//send status fail
		echo "fail";




STEP 3: Coding of The Android client

As in the screenshot, the layout is in the layout xml file. This activity is created from the Basic Activity. Kindly download the project folder for the complete code.

insert-record-screen is the helper class to manage the online connection. Copy and paste to the package folder.


The is the file to handle the GUI and the AsyncTask (multi-threading) code. We are just providing the segment code where the multi-threading of storing the new record in the online database, kindly download the project folder for the complete code.

You may call this class from onClick button by

    public void onClick(View v){
        if (v.getId() {
            id = txtid.getText().toString();
            trainingname = txttrainingname.getText().toString();
            contact = txtcontact.getText().toString();
            website = txtwebsite.getText().toString();
            trainingdesc = txttrainingdesc.getText().toString();

            //call the AsyncTask
            new SaveNewRecord().execute();
        }//end btnsave


The complete SaveNewRecord asynctask

//****************************** Save record process ASYNCTASK, starts here
    public class SaveNewRecord extends AsyncTask<String, Void, String> {
        //the progressdialog
        ProgressDialog progress = new ProgressDialog(InsertRecord.this);
        protected void onPreExecute(){
            //set message of the dialog
            progress.setMessage("Saving record to online database...");
            //show dialog

        protected String doInBackground(String... arg0) {

            try {
                // here is your URL path, change the IP number to
                // point to your own server
                URL url = new URL("");

                JSONObject postDataParams = new JSONObject();
                //add name pair values to the connection
                postDataParams.put("id", id);
                postDataParams.put("trainingname", trainingname);
                postDataParams.put("contact", contact);
                postDataParams.put("website", website);
                postDataParams.put("trainingdesc", trainingdesc);


                HttpURLConnection conn = (HttpURLConnection) url.openConnection();
                conn.setReadTimeout(15000 /* milliseconds */);
                conn.setConnectTimeout(15000 /* milliseconds */);
                conn.connect();//execute the connection

                OutputStream os = conn.getOutputStream();
                BufferedWriter writer = new BufferedWriter(
                        new OutputStreamWriter(os, "UTF-8"));


                int responseCode=conn.getResponseCode();
                Log.e("responseCode", "responseCode "+responseCode);
                if (responseCode == HttpsURLConnection.HTTP_OK) {
                    //code 200 connection OK
                    //code 500 server not responding
                    //code 404 file not found
                    //this part is to capture the server response
                    BufferedReader in=new BufferedReader(new

                    StringBuffer sb = new StringBuffer("");
                    String line="";

                        Log.e("MSG sb",sb.toString());

            //call method to handle after verification
            if(progress != null && progress.isShowing()){

    public String getPostDataString(JSONObject params) throws Exception {

        StringBuilder result = new StringBuilder();
        boolean first = true;

        Iterator<String> itr = params.keys();

            String key=;
            Object value = params.get(key);

            if (first)
                first = false;

            result.append(URLEncoder.encode(key, "UTF-8"));
            result.append(URLEncoder.encode(value.toString(), "UTF-8"));

        return result.toString();
    }//end sendPostData

    public void saveVerification(String svrmsg){
        String savemsg="";
        //if new record successfully saved
        Toast.makeText(this, "svrmsg:"+svrmsg, Toast.LENGTH_LONG).show();
        if (svrmsg.equals("success")){

Since HttpClient is not supported any more in Android SDK 23, I have to resort to org.json.JSONObject and library to do online database with JSON. The objective of this tutorial is to log-in from a mobile client with the username and password stored in an online database facility. STEP 1: Create a new Android project, this time choose the LoginActivity .
