private Button btnCreateProduct;    
private ProgressDialog pDialog;


JSONParser jsonParser = new JSONParser();


// JSON Node names
private static final String TAG_SUCCESS = "success";
private static final String TAG_MESSAGE = "message";

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

//   new MyAsyncTask().execute();


inputCompanyID = (EditText) findViewById(R.id.inputCompanyID);
inputBranchID = (EditText) findViewById(R.id.inputBranchID);
inputLName = (EditText) findViewById(R.id.inputLName);
inputFName = (EditText) findViewById(R.id.inputFName);

btnCreateProduct = (Button) findViewById(R.id.btnAddCustomer);

    }



    public void sendCustomer() {
        List<NameValuePair> params = new ArrayList<NameValuePair>();
        params.add(new BasicNameValuePair("oAuth", "test123"));
        params.add(new BasicNameValuePair("action", "add-customer"));
        params.add(new BasicNameValuePair("company_id", inputCompanyID.getText().toString()));
        params.add(new BasicNameValuePair("branch_id", inputBranchID.getText().toString()));
        params.add(new BasicNameValuePair("lastname", inputLName.getText().toString()));

         Log.e("PARAMS",""+response);

         return;

                                }

                            }
                        }).start(); 
                        return null;

Few things you can adjust in your code:

SendCustomer does not return anything, but your asyncTask returns a String for doInbackground().

Also no need to convert to a string when you getText(), it's redundant.

So change sendCustomer like this:

public String sendCustomer() {
    List<NameValuePair> params = new ArrayList<NameValuePair>();
    params.add(new BasicNameValuePair("oAuth", "test123"));
    params.add(new BasicNameValuePair("action", "add-customer"));
    params.add(new BasicNameValuePair("company_id", inputCompanyID.getText()));
    params.add(new BasicNameValuePair("branch_id", inputBranchID.getText()));
    params.add(new BasicNameValuePair("lastname", inputLName.getText()));
    params.add(new BasicNameValuePair("firstname", inputFName.getText()));
    params.add(new BasicNameValuePair("gender_id", inputGenderID.getText()));
    params.add(new BasicNameValuePair("birth_date", inputBirthdate.getText()));
    params.add(new BasicNameValuePair("email", inputEmail.getText()));
    params.add(new BasicNameValuePair("mobile", inputMobile.getText()));
    params.add(new BasicNameValuePair("item_id", inputItemID.getText()));
    params.add(new BasicNameValuePair("voucher_id", inputVoucherID.getText()));

    String url = "http://192.168.0.110/teezly/API/1.0/customer.php";  
    String response = ISparkLib.getHttpResponse(url, params);
    Log.e("PARAMS",""+response);

 return response;
}

AsyncTask is already a thread no need to use a thread inside of it, thats the whole point.

Change `doInbackground like this:

@Override
protected String doInBackground(String... params) {
    return sendCustomer();
}

you can read the result inside of onPostExecute

protected void onPostExecute(String result) {
   // do something with the result
    Log.e("PARAMS","result =" + result);
 }

When posting to PHP server it is very easy to read the POST variable

in customer.php do this

 <?php
 if(isset($_POST)){
    //to check the data
    var_dump($_POST);
    //get the value assign them to variables
    $oAuth = $_POST['oAuth'];
    $action = $_POST['action'];
    $company_id = $_POST['company_id'];
    $branch_id = $_POST['branch_id'];
    $lastname = $_POST['lastname'];
    $firstname = $_POST['firstname'];
    $gender_id = $_POST['gender_id'];
    $birth_date = $_POST['birth_date'];
    $email = $_POST['email'];
    $mobile = $_POST['mobile'];
    $item_id = $_POST['item_id'];
    $voucher_id = $_POST['voucher_id'];
 }
 ?>

There are other things you could do to improve your code. I hope this is helpful to get you started!
